Answer:

b 15 gallons of fuel for $60.50

Step-by-step explanation:

because 1 gallon of fuel is for $4.299

and when you multiply 15×4.299 the answer is 64.485 which is greater than the offer you are getting it for.

you could explain lets say over the holidays Miss. So and So's class's kids got an average of around 4-6 Christmas presents while Miss. Mary Sue's class had  kids with 2 presents and kids with 12, since the range between 2-12 is bigger it had a greater standard of deviation

(hopefully this helps and I am not overcomplicating or incorrecting the standard of deviation, good luck)

Answer:

  (x, y) = (10, 2)

Step-by-step explanation:

The upper angle marked with an expression in x and y is supplementary to the angle marked 70°. The lower angle marked with an expression in x and y is an alternate interior angle with respect to the one marked 70°, is equal to that. This gives the two equations in x and y:

  6x +10y +30 = 110

  4x +10y +10 = 70

Subtracting the second equation from the first gives ...

  2x +20 = 40

  x +10 = 20 . . . . . divide by 2

  x = 10 . . . . . . . . . subtract 10

Substituting into the second equation gives ...

  4(10) +10y +10 = 70

  4 + y + 1 = 7 . . . . . . . . divide by 10

  y = 2 . . . . . . . . . . . . . . subtract 5

The values of x and y are 10 and 2, respectively.

To make 100 ml of 25% saline solution, Riley will need 50 ml = 12% saline mixture and 50 ml= 38% saline mixture.

Given,

We have 12% and 38% of saline mixtures.

We need to find the amount in ml from each saline mixture which would give us 100 ml of 25%.

What are the methods to solve a system of linear equations?

There are a number of methods but the most and easiest used method is the substitution method and the elimination method.

We can make two linear equations from the given statements.

Let x = amount from 12% saline mixture and y = amount from 38% saline mixture.

Now we need to make 100 ml of 25% saline.

so,

x + y = 100.

So we have two equations.

x + y = 100..............(1)

12% of x + 38% of y = 100 x 25%

0.12x + 0.38 = 25 ...............(2)

Using the substitution method we have,

x = 100 - y

Putting x = 100 - y in {2}

0.12 ( 100 - y ) + 0.38y

= 2512 - 0.12y + 0.38y

= 250.38y - 0.12y

= 25 - 120.26y = 13y

= 13 / 0.26y = 50.

Putting y = 50 in (1)

x + y = 100x

100 -50x = 50.

So Riley will need 50 ml = 12% saline mixture and 50ml = 38% saline mixture to make 100 ml of 25% saline solution.

Answer:

1/2 or 50% probability

Step-by-step explanation:

There are just two players, player A and player B. Since it is between this two players, for player A to score first we would have:

AB where player A is the first player to score, we wouldn't have BA since player would not be the first here

Probability = number of favorable outcomes/total number of outcomes

Therefore probability of A being the first player = number of A/total number of players

=1/2 = 0.50

There is therefore a 50% chance of A being the first player

Answer:

g = 6

Step-by-step explanation:

5.2g + 10 = 2.2g + 28 (Given)

3g + 10 = 28 (Subtracted 2.2g on both sides)

3g = 18 (Subtracted 10 on both sides)

g = 6 (Divided 3 on both sides)

To check to make sure you are correct, simply substitute your answer for g:

5.2(6) + 10 = 2.2(6) + 28

31.2 + 10 = 13.2 + 28

41.2 = 41.2

You'll know you're correct if they both equal the same. In this case, the solution works.

Answer:

(40+ 19) – 38

Step-by-step explanation:

We need to find the expression for "thirty-eight less than the sum of forty and nineteen".

Sum of forty and nineteen = 40 + 19

38 less than the above is 40 + 19 - 38

Overall expression is :

(40 + 19) - 38

Hence, the correct option is (d) "(40+ 19) – 38".

Answer:

x = 14

Step-by-step explanation:

(6x - 12)° + (8x - 4)° = 180° (Supplementary angles)

6x - 12 + 8x - 4 = 180

Add like terms

14x - 16 = 180

14x = 180 + 16

14x = 196

x = 196/14

x = 14

Answer:

[tex]f^{-1}(x)= \frac{3}{2}(x+6)[/tex]

[tex]f(f^{-1}(x)) = f^{-1}(f(x))= x[/tex]

Step-by-step explanation:

Given

[tex]f(x) = \frac{2}{3}x - 6[/tex]

Required

Determine [tex]f^{-1}(x)[/tex]

[tex]f(x) = \frac{2}{3}x - 6[/tex]

Represent f(x) as y

[tex]y=\frac{2}{3}x - 6[/tex]

Swap the positions of x and y

[tex]x=\frac{2}{3}y - 6[/tex]

Add 6 to both sides

[tex]x+6=\frac{2}{3}y - 6+6[/tex]

[tex]x+6=\frac{2}{3}y[/tex]

Multiply both sides by 3

[tex]3(x+6)=\frac{2}{3}y * 3[/tex]

[tex]3(x+6)=2y[/tex]

Divide both sides by 2

[tex]\frac{3}{2}(x+6)=\frac{2y}{2}[/tex]

[tex]\frac{3}{2}(x+6)=y[/tex]

[tex]y= \frac{3}{2}(x+6)[/tex]

Replace y with [tex]f^{-1}(x)[/tex]

[tex]f^{-1}(x)= \frac{3}{2}(x+6)[/tex]

Justify the result:

First, we solve for [tex]f(f^{-1}(x))[/tex]

[tex]f(x) = \frac{2}{3}x - 6[/tex]

[tex]f(x) = \frac{2}{3}x - 6[/tex] becomes

[tex]f(f^{-1}(x)) = \frac{2}{3}x - 6[/tex]

Substitute [tex]\frac{3}{2}(x + 6)[/tex] for x

[tex]f(f^{-1}(x)) = \frac{2}{3}(\frac{3}{2}(x + 6)) - 6[/tex]

[tex]f(f^{-1}(x)) = \frac{2*3}{3*2}(x + 6)- 6[/tex]

[tex]f(f^{-1}(x)) = \frac{6}{6}(x + 6)- 6[/tex]

[tex]f(f^{-1}(x)) = 1*(x + 6)- 6[/tex]

[tex]f(f^{-1}(x)) = x + 6- 6[/tex]

[tex]f(f^{-1}(x)) = x[/tex]

Next, we solve [tex]f^{-1}(f(x))[/tex]

[tex]f^{-1}(x)= \frac{3}{2}(x+6)[/tex]

[tex]f^{-1}(x)= \frac{3}{2}(x+6)[/tex] becomes

[tex]f^{-1}(f(x))= \frac{3}{2}(x+6)[/tex]

Substitute [tex]\frac{2}{3}x - 6[/tex] for x

[tex]f^{-1}(f(x))= \frac{3}{2}(\frac{2}{3}x) - 6+6[/tex]

[tex]f^{-1}(f(x))= \frac{3}{2}(\frac{2}{3}x)[/tex]

[tex]f^{-1}(f(x))= \frac{2*3}{3*2}x[/tex]

[tex]f^{-1}(f(x))= \frac{6}{6}x[/tex]

[tex]f^{-1}(f(x))= 1*x[/tex]

[tex]f^{-1}(f(x))= x[/tex]

Hence:

[tex]f(f^{-1}(x)) = f^{-1}(f(x))= x[/tex]

Answer:

Each fudge cookie has 80 calories.

Each lemon cream has 65 calories.

Step-by-step explanation:

We will let [tex]\ell[/tex] represent the calories in lemon creams and [tex]f[/tex] represent the calories in fudge cookies.

Two lemon creams and four fudge cookies together have 450 calories. So, we can write the following equation:

[tex]2\ell+4f=450[/tex]

And four lemon creams plus two fudge cookies together have 420 calories. So, we can write the following equation:

[tex]4\ell+2f=420[/tex]

We now have a system of equations. We can solve this by elimination.

For the first equation, we can multiply both sides by -2. This way, the [tex]\ell[/tex] will cancel when we add the two equations together.

So, the first equation becomes:

[tex]-4\ell-8f=-900[/tex]

Add this to the second equation. Hence:

[tex](-4\ell+4\ell)+(-8f+2f)=(-900+420)[/tex]

Simplify:

[tex]-6f=-480[/tex]

Divide both sides by -6. Hence:

[tex]f=80[/tex]

So, there are 80 calories in one cookie.

We can use the first equation again to find the amount of calories in one cream. We have:

[tex]2\ell+4f=450[/tex]

Substituting 80 for [tex]f[/tex] yields:

[tex]2\ell+320=450[/tex]

Then it follows that:

[tex]\ell=65[/tex]

So, there are 65 calories in each lemon cream.

Answer:

69.04

Step-by-step explanation:

Given that:

Mean (m) = 69.0

Standard deviation (s) = 2.8

Zscore = 0.2

Find the corresponding height (x) ;

Using the relation :

Zscore = (x - m) / s

0.2 = (x - 69.0) / 0.2

0.04 = x - 69.0

0.04 + 69.0 = x

69.04 = x

Hence, the height of a man with a Zscore of 0.2 is 69.04

Answer:

We conclude that the price is 3.5 times the number of board games.

Hence, option B is true.

Step-by-step explanation:

We know that when y varies directly with x, the equation is

y ∝ x

y = kx

k = y/x

where 'k' is called the proportionality constant.

From the table,

For the point (2, 7)

k = y/x

  = 7/2

  = 3.5

For the point (4, 14)

k = y/x

   = 14 / 4

   = 7/2

    = 3.5

For the point (5, 17.50)

k  = y/x

   = 17.5 / 5

   = 3.5

For the point (9, 31.50)

k  = y/x

   = 31.50 / 9

   = 3.5

From the above calculations, we computed that the value of the proportionality constant remains the same.

Thus, the table of numbers represents a proportional relationship.

Therefore, the equation becomes

y = kx

The price of 2 board game

y = 3.5 (2)

  = 7

The price of 4 board game

y = 3.5 (4)

  = 14

Therefore, we conclude that the price is 3.5 times the number of board games.

Hence, option B is true.

Answer:

  70°

Step-by-step explanation:

Angles 2 and 13 are alternate exterior angles, so are congruent. The value of x can be found by solving the equation that equates the expressions for the measures of these angles. Once x is found, the measure of angle 13 can be determined. The measure of angle 9 is the supplement of angle 13.

So, ...

  m∠2 = m∠13

  8x +14 = 10x -10

  24 = 2x  . . . . . . . .  add 10-2x

  12 = x

  m∠13 = 10x -10 = 10·12 -10 = 110

  m∠9 = 180° -110°

  m∠9 = 70°
