The probability of selecting a vowel from a hat with letters of the alphabet is 5/26 or approximately 0.1923. There are 5 vowels and 26 total letters.

There are 5 vowels in the English alphabet: A, E, I, O, and U. Therefore, the number of favorable outcomes (i.e., the number of vowels in the hat) is 5.

There are a total of 26 letters in the English alphabet. Therefore, the number of possible outcomes (i.e., the number of letters in the hat) is 26.

The probability of selecting a vowel is the ratio of the number of favorable outcomes to the number of possible outcomes:

P(vowel) = number of favorable outcomes / number of possible outcomes

P(vowel) = 5 / 26

Therefore, the probability of selecting a vowel is 5/26 or approximately 0.1923 (rounded to four decimal places).

Because the critical region is all on one side in a one-tailed test and needs to be split between the two tails in a two-tailed test.

In a one-tailed test, the alternative hypothesis is directional and the critical region is all on one side of the distribution. In a two-tailed test, the alternative hypothesis is non-directional and the critical region is split between the two tails of the distribution.

It is easier to reject the null hypothesis with a one-tailed test because the critical region is all on one side of the distribution, making it more likely to observe a significant difference and reject the null hypothesis. In contrast, the critical region is split between the two tails in a two-tailed test, making it less likely to observe a significant difference and reject the null hypothesis.

Answer:

The diameter of the circle is 12 inches, which means the radius of the circle is half of the diameter, or 6 inches.

The formula for the area of a circle is:

A = πr^2

where A is the area of the circle and r is the radius.

Plugging in the value for the radius, we get:

A = π(6 in)^2

A = π(36 in^2)

A = 113.1 in^2 (rounded to one decimal place)

Therefore, the area of the circle is approximately 113.1 square inches.

The effect on the graph of the function f(x) = 2^x when f(x) is replaced with f(x − 3) is that it translates horizontally 3 units right.

When a function is replaced with f(x - c), where c is a positive constant, the graph of the function shifts horizontally c units to the right. Similarly, if c is negative, the graph shifts horizontally c units to the left.

Therefore, replacing f(x) with f(x - 3) in the function f(x) = 2^x shifts the graph of the function horizontally by 3 units to the right.

Step-by-step explanation:

If the population growth rate is 3.5 percent every year then the population of the town after 7 years would be 14940.

Given that population grows 3.5 percent every year.

So, the increase in population after one year

= 3.5% of 12000

= (3.5/100) × 12000

= 420

Thus the increase in population after 7 year would be,

= population increase in one year × 7

= 420×7 = 2940

Hence population of the town after 7 years = (present population + increase in population)

= 12000 + 2940

= 14940

So the population of the town after 7 years with 3.5 % growth every year would be 14490.

Answer:

Step-by-step explanation:

For each increase of one unit on the x-axis (the horizontal axis), the amount on the y-axis (the vertical axis) increases by the slope of the line.

Slope is the amount of change in the y-axis that occurs as a result of a one-unit change in the x-axis. It is also known as the rise over run.

A positive slope indicates that the line rises from left to right, while a negative slope indicates that the line falls from left to right. If the slope is zero, the line is horizontal.

The slope of a horizontal line is zero, and the slope of a vertical line is undefined because the x or y coordinate does not change as the other changes.

Therefore, the slope of a line represents the amount by which the value on the y-axis increases for every increase of one unit on the x-axis

Around noon, when the forecast temperature is about 4 degrees Celsius higher than the measured temperature, the difference is at its greatest.

The strength and direction of the linear connection between two variables are measured by the correlation coefficient. Its value goes from -1 to 1, and it is represented by the symbol "r". A perfect negative correlation, or r = -1, implies that as one variable rises, the other variable falls in an exact predictable manner. There is no linear relationship between the two variables if r = 0, which implies there is no correlation between the two variables. When r = 1, there is a perfect positive correlation, meaning that when one measure rises, the other rises in an exact predictable manner.

Answer:

  5. 3 cm × 2 cm × 7 cm

  6. f(x) = x³ -3x² -x +3

Step-by-step explanation:

You want the dimensions of a cuboid with edges marked (x-1), (x-2), and (x+3) and a volume of 42 cm³. You also want the coefficients of a monic cubic f(x) with values f(2) = -3, f(-3) = -48, and f(-1) = f(1).

The volume of the cuboid is the product of its dimensions, so we have ...

  V = LWH

  42 = (x -1)(x -2)(x +3)

The value of x can be found as the solution to this equation. A graphical solution is attached. It shows x=4, so the dimensions are ...

  4 -1 = 3

  4 -2 = 2

  4 +3 = 7

The dimensions of the cuboid are 3 cm by 2 cm by 7 cm.

Note that the prime factors of 42 are 2, 3, 7, which have the required differences. You don't really need a polynomial to guess these are the dimensions.

The expanded polynomial is x³ -7x -36 = 0, so potential rational roots will be from the set {1, 2, 3, 4, 6, 9, 12, 18, 36}. An estimate of the upper bound of the real root puts it at ∛36 +√7 ≈ 5.9. We require x > 2, so the viable choices for testing are 3 and 4. x=4 is the solution.

The remainder theorem tells you that the remainder from dividing f(x) by (x-a) is f(a). To obtain linear equations in b, c, d, we can rearrange the function to ...

  bx² +cx +d = -x³ +f(x)

For x = ±1, we know the remainders f(x) are the same, so we can look at the difference of the equations for these x-values.

  (b(-1)² +c(-1) +d) - (b(1)² +c(1) +d) = (-(-1)³ +f(-1)) - (-(1)³ +f(1))

  b -b -c -c +d -d = 1 -(-1)

  -2c = 2

We can fill in values x=2, x=-3 to get two more equations in b, c, d. The coefficients of the three equations we have for the three unknowns are shown in the second attachment. The third attachment shows the solution of these equations is (b, c, d) = (-3, -1, 3).

The table in the first attachment confirms the remainders using these coefficients.

5)The dimensions of the rectangular prism are 3 , 7 and 2.

6) f(x) = x³ - 3x² - x + 3

Step-by-step explanation:

5) The volume of rectangular prism = l*w*h.

    l*w*h= 42

(x- 1)(x -2)(x+3) = 42

We can find (x - 2) *(x + 3) using the identity (x + a)(x + b) = x² + (a +b)*x + ab

(x - 2)(x + 3) =x² + (-2 +3)x + (-3)*2

                   = x² + 1x - 6

(x -1)(x + 3)(x - 2) = 42

(x - 1)(x² + x - 6) = 42

x*x² + x*x - 6*x + (-1)*x² + (-1) *x + (-1)(-6) = 42

x³ + x² - 6x - x² - x + 6 - 42 = 0

x³ + x² - x² - 6x - x + 6 -42 = 0

Combine the like terms,

   x³ - 7x - 36 = 0

Find the zeros of the cubic polynomial by synthetic division method.

                      4       16       36

              1       4       9          0

x - 4 is zero of the polynomial.  

Ignore the quadratic polynomial x² + 4x  + 9 as it will have irrational roots(zeros) and dimensions will be always positive integer.

x - 4 = 0

x = 4

length =  x - 1     =  4 - 1 = 3

Width  =   x + 3 = 4 + 3 = 7

Height =  x - 2 = 4 - 2  = 2

The dimensions of the rectangular prism are 3 , 7 and 2.

It is given that when f(x) is dived by x + 1 and x- 1, the remainders are same.

   x + 1 = 0              ; x - 1 = 0

         x = -1             ;      x = 1

                       f(-1) =  f(1)

         -1 + b -  c + d = 1 + b + c + d

-1 -1 + b - b - c - c + d - d = 0

The sum of the deviations of the individual data elements from their mean is always equal to zero. Correct option is A.

This is because the deviation is defined as the difference between each data point and the mean of all the data points.

Since the mean is calculated as the sum of all the data points divided by the total number of data points, the positive deviations from the mean must be balanced out by the negative deviations from the mean. In other words, for every data point that is above the mean, there is a corresponding data point that is below the mean.

When we add up all the deviations from the mean, the positive deviations will cancel out the negative deviations, resulting in a sum of zero. This property of the sum of deviations from the mean is fundamental to many statistical concepts, such as variance and standard deviation.

Therefore, the correct answer to the question is (a) equal to zero, since the sum of the deviations from the mean is always zero.

The area of the figure composing of a rectangle and a semi-circle is 105.12 ft².

The figure in the image composes of a rectangle and a semi-circle.

The area of a rectangle is expressed as;

Area = Length × Width

The area of a semi-circle is expressed as;

Area = 1/2 × πr²

First, we find the area of the rectangle.

Area = Length × Width

Plug in Length = 10ft and Width = 8ft

Area = 10ft × 8ft

Area = 80ft²

Next, find the area of the semi-circle.

Area = 1/2 × πr²

Since diameter = 8ft, radius r = diameter/2 = 8ft/2 = 4ft

Area = 1/2 × 3.14 × (4ft)²

Area = 1/2 × 3.14 × 16 ft²

Area = 25.12 ft²

Now, area of the composite figure will be:

Area of the rectangle + Area of the semi-circle.
