determine whether the property is true for all integers, true for no integers, or true for some integers and false for other integers. justify your answers. the average of any two odd integers is odd.

Answers

Answer 1

The property of the average of any two odd integers being odd is true for all integers.

This is because the sum of any two odd integers is always an even integer. For example, if we take any two odd integers, say 3 and 7, then the sum of these two is 10, an even integer. Therefore, the average of 3 and 7, which is (3 + 7)/2, is also an even integer, in this case, 5.

Since all even integers are divisible by 2, the average of any two odd integers must be an odd integer.

Therefore, the property is true for all integers.

Answers

Answer:

y = 8x-19

Step-by-step explanation:

The first step is to find the slope.

m= ( y2-y1)/(x2-x1)

  = ( 13-5)/(4-3)

   = 8/1

  = 8

Then we can use the slope intercept formula.

y = mx+b

y = 8x+b

Substitute a point to find the intercept.

5 = 8*3+b

5 = 24+b

-19 = b

The formula is

y = 8x-19

Answer:

y = 8x - 19

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (3, 5 ) and (x₂, y₂ ) = (4, 13 )

m = [tex]\frac{13-5}{4-3}[/tex] = [tex]\frac{8}{1}[/tex] = 8 , then

y = 8x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (3, 5 )

5 = 8(3) + c = 24 + c ( subtract 24 from both sides )

- 19 = c

y = 8x - 19 ← equation of line

the combined area of the garden and the walkway when the width of the walkway is 4 feet is LW + 8L + 8W + 64 square feet.

why it is?

Let's assume that the length of the rectangular garden is L and the width is W. Let the width of the walkway be x.

a. The area of the rectangular garden is L x W. The combined area of the garden and the walkway is the area of the larger rectangle formed by the outer boundary of the walkway. The length of this larger rectangle is (L + 2x) and the width is (W + 2x). Therefore, the polynomial that represents the combined area of the garden and the walkway is:

(L + 2x)(W + 2x)

Expanding this expression, we get:

LW + 2Lx + 2Wx + 4x²2

So, the polynomial that represents the combined area of the garden and the walkway is LW + 2Lx + 2Wx + 4x²2.

b. If the width of the walkway is 4 feet, then x = 4. Substituting this value in the polynomial we obtained in part (a), we get:

LW + 2L(4) + 2W(4) + 4(4)²2

Simplifying this expression, we get:

LW + 8L + 8W + 64

Therefore, the combined area of the garden and the walkway when the width of the walkway is 4 feet is LW + 8L + 8W + 64 square feet.

There is only one possible triangle that can be drawn with one angle measuring 30 deg and another measuring 110°. This is because all triangles have a sum of 180° for the three angles.

What is triangle ?

Triangle is a three-sided polygon with three straight sides that intersect at three vertices. It is one of the basic shapes in geometry, and is considered to be a building block of other shapes. Triangles can be classified according to their sides, angles, and area. The most common types of triangles are equilateral, isosceles, and scalene triangles, which are classified according to the length of their sides. Triangles can also be classified according to their angles, as acute, right, and obtuse triangles, which are classified according to the size of their angles. Additionally, the area of a triangle is determined by its base, height, and side lengths.

Therefore if one angle is 30° and the other is 110°, the third angle must be 40° for the triangle to be valid.

b 5000 c 3174 d 1/2 of the area of 1 standard deviation

Answers

Correct option is (c) 3174

The probability that a randomly selected case will have a score beyond either +1.00 or -1.00 standard deviation of the mean depends on the type of distribution and the area under the curve beyond these values.

Assuming a normal distribution, approximately 68% of the cases fall within one standard deviation from the mean, and approximately 32% of the cases fall beyond either +1.00 or -1.00 standard deviation of the mean.

To calculate the probability of a randomly selected case falling beyond either +1.00 or -1.00 standard deviation of the mean, we need to calculate the area under the curve beyond these values. Since the distribution is symmetric, we can calculate the area on one side of the mean and multiply it by 2.

Using a standard normal distribution table or calculator, we can find the area under the curve beyond +1.00 standard deviation from the mean as 0.1587 and the area under the curve beyond -1.00 standard deviation from the mean as 0.1587.

Therefore, the total probability of a randomly selected case falling beyond either +1.00 or -1.00 standard deviation of the mean is 0.1587 + 0.1587 = 0.3174, which is approximately 32%.

Hence, the correct option is (c) 3174.

As a result, there is a about 74.53 degree elevation difference between the ladder and the ground.

what is angle ?

A geometric shape known as an angle is created when two rays or line segments come together at a location known as the vertex. The sides of the angle are the rays or line segments. Angles are used to define the amount of rotation or inclination between two lines or planes and are commonly measured in degrees or radians. The most popular unit of measurement for angles is the degree, which is derived from the 360 equal divisions of a circle. Angles are measured in degrees using a protractor, and each component is referred to as a degree.

given

We may resolve this issue using trigonometric functions. The elevation angle between the ladder and the ground will be denoted by the symbol. Next, we have

opposite/hypotenuse of sin()

adjacent/hypotenuse = cos()

The building's height in this instance serves as the opposing side, and the length of the ladder serves as the hypotenuse. We thus have:

height/35 cos() = 9.7/35 sin()

By rearranging the first equation, we can find the height:

height equals 35*sin()

The second equation can then be changed to include the following expression:

cos(θ) = 9.7/35

cos(θ) = 0.2771

By taking the inverse cosine of both sides, we can now solve for :

θ = cos^(-1)(0.2771) (0.2771)

7.453 degrees

As a result, there is a about 74.53 degree elevation difference between the ladder and the ground.

a bridge hand consists of 13 cards from a deck of 52. find the probability that a bridge hand includes exactly 4 aces and exactly 3 kings.

Answers

The probability that a bridge hand includes 4 acres and exactly 3 kings is 0.028%

To find the probability of getting exactly 4 aces and 3 kings in a bridge hand, we can use the following formula:

P(4 aces and 3 kings) = (number of ways to get 4 aces and 3 kings) / (number of ways to select 13 cards from a deck of 52)

To calculate the numerator, we can first find the number of ways to choose 4 aces from the 4 available in the deck, and then the number of ways to choose 3 kings from the 4 available in the deck. The remaining 6 cards can be any of the 44 non-ace, non-king cards. Therefore:

Number of ways to get 4 aces and 3 kings = (4 choose 4) x (4 choose 3) x (44 choose 6) = 1 x 4 x 44,380,776 = 177,523,104

To calculate the denominator, we can find the total number of ways to choose any 13 cards from the 52-card deck:

Number of ways to select 13 cards from a deck of 52 = (52 choose 13) = 635,013,559,600

Therefore, the probability of getting exactly 4 aces and 3 kings in a bridge hand is:

P(4 aces and 3 kings) = (number of ways to get 4 aces and 3 kings) / (number of ways to select 13 cards from a deck of 52) = 177,523,104 / 635,013,559,600 = 0.0002799 or approximately 0.028%.

Step-by-step explanation:

The red graph is obtained by shifting the graph of f(x) = 4 - x² upwards by some amount. We can see that the highest point on the red graph occurs at x = 0, where the value is 4.

To shift the graph of f(x) upwards by 3 units, we can add 3 to the entire function:

f(x) + 3 = 4 - x² + 3

= 7 - x²

So the equation of the red graph is:

g(x) = 7 - x²

Therefore, the correct answer is option C: g(x) = 7 - x².

cubic feet. The box has a length of
(x + 8) feet, a width of x feet, and a height of (x − 2) feet. Find the dimensions of the box.

Answers

Answer:

Step-by-step explanation:

To find the dimensions of the box, we need to solve for the value of x in the expressions given for its length, width, and height.

The volume of a box is given by multiplying its length, width, and height, so we can write:

V = (x+8) * x * (x-2)

Expanding the expression, we get:

V = (x^3 + 6x^2 - 16x)

We know that the volume of the box is measured in cubic feet, so we can assume that V is a positive value. Therefore, we can set V equal to some positive number, such as 1000 or 2000, and solve for x using algebraic techniques such as factoring or the quadratic formula.

For example, if we set V = 1000, we can write:

1000 = x^3 + 6x^2 - 16x

Simplifying and rearranging the terms, we get:

x^3 + 6x^2 - 16x - 1000 = 0

Using a graphing calculator or other mathematical software, we can find that the real solution to this equation is approximately x = 10.5.

Therefore, the dimensions of the box are:

- Length: x+8 = 18.5 feet

- Width: x = 10.5 feet

- Height: x-2 = 8.5 feet

how many 3-digit numbers can be formed using the digits 0, 1, 2, 3, 4, 5, 6, if repetition of digits is not allowed?

Answers

There are 35 different 3-digit numbers that can be formed using the digits 0, 1, 2, 3, 4, 5, 6, if the repetition of digits is not allowed.

What is probability?

Probability is a branch of mathematics that deals with the study of randomness and uncertainty in events. It is the measure of the likelihood or chance that an event will occur. Probability is expressed as a number between 0 and 1, where 0 indicates that the event will not occur and 1 indicates that the event will occur with certainty.

According to the given information :

To form a 3-digit number using the given set of 7 digits (0, 1, 2, 3, 4, 5, 6) without repetition, we need to choose 3 different digits from the set.

We can count the number of ways to select 3 distinct digits from the set of 7 using the combination formula, which is:

C(n, k) = n! / (k! * (n-k)!)

Where n is the total number of items in the set, and k is the number of items we want to choose.

In this case, n = 7 (because we have 7 digits to choose from), and k = 3 (because we want to choose 3 digits to form a 3-digit number).

Therefore, the number of ways to select 3 distinct digits from the set of 7 is:

C(7, 3) = 7! / (3! * 4!)

= (7 * 6 * 5 * 4 * 3 * 2 * 1) / ((3 * 2 * 1) * (4 * 3 * 2 * 1))

= (7 * 6 * 5) / (3 * 2 * 1)

= 35

Therefore, there are 35 different 3-digit numbers that can be formed using the digits 0, 1, 2, 3, 4, 5, 6, if the repetition of digits is not allowed.

Answers

By the 46th day, there are 400 water lilies in the pond. the estimate you made: a). close to 46 (or exactly right) because it was estimated well.

We know that the regression equation is: y = 3.915(1.106)ˣ and that the pond can hold 400 water lilies.

y = 3.915(1.106)ˣ

Here, y is equal to the number of water lilies the pond can hold.

So, y = 400

And,  x is the required time taken.

So,

400 = 3.915(1.106)ˣ

⇒ (1.106)ˣ = 400/3.915    

⇒ (1.106)ˣ = 102.17

Taking logarithm on both sides, we get

log (1.106)ˣ = log (102.17)

⇒ x log (1.106) = log (102.17) .............. [log aˣ = x loga]

⇒ x = [log (102.17)/log (1.106)]    

⇒ x = 45.92

Answer:

We can check which dimensions are possible for the rectangle by finding the product of the width and length and seeing if it equals the given area of (24x + 30) square units.

Let's check each option:

width 6 units; length (4x + 5) units

Area = 6(4x + 5) = 24x + 30

This option is possible.

width 4 units; length (6x + 7) units

Area = 4(6x + 7) = 24x + 28

This option is not possible since the area is not equal to (24x + 30).

width 3 units; length (21x + 27) units

Area = 3(21x + 27) = 63x + 81

This option is not possible since the area is not equal to (24x + 30).

width 8 units; length (3x + 4) units

Area = 8(3x + 4) = 24x + 32

This option is not possible since the area is not equal to (24x + 30).

width 2 units; length (15 + 12x) units

Area = 2(15 + 12x) = 30 + 24x

This option is not possible since the area is not equal to (24x + 30).

Therefore, the only possible dimension for the rectangle is width 6 units and length (4x + 5) units.

is tderiv one-to-one? explain the significance of this result in terms of the derivative on polynomials.

Answers

The total derivative of a function is not necessarily one-to-one. The total derivative represents the change in a function with respect to all of its input variables.

If a function has multiple input variables, the total derivative is a matrix, called the Jacobian matrix, whose entries represent the partial derivatives of the function with respect to each input variable.

A function with a non-invertible Jacobian matrix is not one-to-one, since multiple input values can result in the same output value. For example, consider the function f(x,y) = (x^2, y^2). The total derivative of f is given by the Jacobian matrix:

| 2x 0 |

| 0 2y|

This matrix is non-invertible when x=0 or y=0, since it has a determinant of zero. Thus, the function f is not one-to-one when x=0 or y=0.

In terms of polynomials, the total derivative is important for determining whether a polynomial has multiple roots. A root of a polynomial is a value of the input variable that causes the polynomial to equal zero. If a polynomial has multiple roots, it is not one-to-one, since different input values can result in the same output value.

The total derivative of a polynomial can be computed using the power rule of differentiation. For example, consider the polynomial p(x) = x^3 - 6x^2 + 11x - 6. The total derivative of p with respect to x is:

p'(x) = 3x^2 - 12x + 11

If p'(x) has multiple roots, then p(x) has multiple roots as well. In this case, p'(x) has roots at x=1 and x=11/3, so p(x) has multiple roots at x=1 and x=3. Thus, the total derivative is useful for identifying when a polynomial is not one-to-one.

a children's liquid medicine contains 100 mg of the active ingredient in 5 ml . if a child should receive 300 mg of the active ingredient, how many milliliters of the medicine should the child be given? for the purposes of this question, assume that these numbers are exact.

Answers

The child should be given 15 ml of the medicine to receive 300 mg of the active ingredient.

The given problem requires us to determine the number of milliliters of a liquid medicine that a child should receive in order to obtain a specific dosage of the active ingredient. We are given that the medicine contains 100 mg of the active ingredient in 5 ml.

The child needs to receive 300 mg of the active ingredient, and there are 100 mg of the active ingredient in 5 ml of the medicine. Therefore, the child should be given:

[tex]\frac{300 mg}{100mg/5ml} = \frac{300\text{ mg} \times 5\text{ ml}}{100\text{ mg}} = 15\text{ ml}$$[/tex]

So the child should be given 15 ml of the medicine to receive 300 mg of the active ingredient.

An airplane is 5,000 ft above ground and has to land on a runway that is 7,000 ft away as shown above. Let x be the angle the pilot takes to land the airplane at the beginning of the runway. Which equation is a correct way to calculate x?

Answers

The fourth equation which is tan x = [tex]\frac{7000}{5000}[/tex] is the correct way to calculate x. This has been obtained by using trigonometry.

What is trigonometry?

Trigonometry is the study of right-angled triangles, which includes the sides, angles, and connections of each triangle.

We are given that the airplane is 5,000 ft above ground and has to land on a runway that is 7,000 ft away with an angle x.

Since, we are not given the hypotenuse so, we will use tan θ.

We know that in trigonometry, tan θ is calculated as the ratio of the opposite side to the adjacent side.

So,

tan x = [tex]\frac{7000}{5000}[/tex]

Hence, the fourth equation is the correct answer.

Kelly is flying a kite to which the angle of elevation is 70 degrees. The string on the kite is 65 meters long. How far is the kite above the ground?

Answers

If Kelly is flying a kite to which the angle of elevation is 70 degrees. The string on the kite is 65 meters long. The kite is about 61 meters above the ground.

How to find the height?

We can use trigonometry to solve the problem. Let's call the height of the kite above the ground "h".

Using trigonometry, we can write:

sin (70) = h / 65

Solving for h, we get:

h = 65 * sin(70)

h= 65 * 0.9397

h ≈ 61 meters

Therefore, the kite is about 61 meters above the ground.

To make balloon animals at birthday parties, Ani charges $3 for each balloon animal plus $8 to cover travel costs. If she made $53 at a party, how many balloon animals did she make?

Answers

Without the travelling cost being $8, Ani made a total of $45 and she made 15 animal balloons.

We know that the total cost Ani charges for travelling is $53

and the total amount Ani made at the party = $53

therefore, first to find the number of balloons she made we need to subtract the travelling cost from the total amount she made:

= 53 - 8 = 45

therefore, now we know that Ani made a total amount $45 from balloons alone:

also, we know that each balloon costs $3 each therefore we need to divide $45 by 3, we get 15,

hence, we can say that Ani made a total of 15 animal balloons for the party.

The percentage of adults who planned to file their taxes electronically is approximately 63%.

A random telephone survey of 1,051 adults (aged 18 and older) was conducted by an online tax preparation and e-filing service. The survey results showed that 664 of those surveyed planned to file their taxes electronically.

Total number of adults surveyed = 1,051

Number of adults who planned to file their taxes electronically = 664

Percentage of adults who planned to file their taxes electronically is;

= (Number of adults who planned to file their taxes electronically / Total number of adults surveyed) x 100%

=(664/1051) x 100%

= 63.16 %

Therefore, the percentage of adults who planned to file their taxes electronically is approximately 63%.
