Araceli uses 9.6 pints of blue paint and white paint to paint her bedroom walls. Three fourths of this amount is blue paint , an

Soloha48 [4]

Answer:

2.4 pints

Step-by-step explanation:

Araceli uses 9.6 pints of blue paint and white paints, that means the total volume of paint is 9.6 pints

If Three fourths of this amount is blue paint ,

Then $\frac{3}{4} X 9.6=7.2 pints$

7.2 pints of blue paint was used.

We want to find out how much white paint was used by Araceli

Volume of Blue Paint+Volume of White Paint=Total Volume of Paint

7.2+Volume of White Paint=9.6

Volume of White Paint=9.6-7.2=2.4 pints

Answer:

Step-by-step explanation:

a systems of equations can be made from the information on the problem

x+y=48

x=2y+3

since x= 2y+3 substitute 2y+3 in the firat equation to get:

(2y+3)+y=48 -> 3y+3=48 -> 3y=45 -> y=15

plug in 15 for y in the second equation to solve for x

x+15 =48 --> x=33

Complete Question

The mean finish time for a yearly amateur auto race was 186.94 minutes with a standard deviation of 0.305 minute. The winning car, driven by Roger, finished in 185.85 minutes. The previous year's race had a mean finishing time of 110.7 with a standard deviation of 0.115 minute. The winning car that year, driven by Karen, finished in 110.48 minutes.

Find their respective z-scores.

Who had the more convincing victory?

A. Roger had a more convincing victory because of a higher z-score.

B. Karen a more convincing victory because of a higher z-score.

C. Roger had a more convincing victory, because of a lower z-score.

D. Karen a more convincing victory because of a lower z-score.

Answer:

The correct option is D

Step-by-step explanation:

From the question we are told that

The mean of the current year is $\mu_c = 186.32 \ minutes$

The standard deviation is $\sigma_c = 0.305 \ minutes$

The time taken by the winning car for the current year is $x = 185.85 \ minutes$

The mean of the previous year is $\mu_p = 110.7 \ minutes$

The standard deviation the previous year is $\sigma_p = 0.115 \ minutes$

The time taken by the winning car for the previous year is $y = 110.48 \ minutes$

Generally the z-score for current year is mathematically evaluated as

$z_c = \frac{x- \mu_c}{\sigma_c }$

=> $z_c = \frac{ 185.85- 186.32}{0.305 }$

=> $z_c = -1.536$

Generally the z-score for previous year is mathematically evaluated as

$z_p = \frac{y- \mu_p}{\sigma_p }$

=> $z_p = \frac{ 110.48-110.7}{0.115 }$

=> $z_p = -1.913$

From the value obtained we see that $z_p < z_c$ , Hence Karen had a more convincing victory because of the lower z -score.

The win-loss record for a football team is 15 wins and 9 losses. What percent of their games did they win?

Burka [1]

Answer:

62.5%

Step-by-step explanation:

To find percentage of win, we simply need to find the number of games won and divide it by the total number of games played. Then we will multiply that answer by 100 (to get percentage).

So,

Number of games won = 15

Total number of games = 15 + 9 = 24

Percentage of Win = $\frac{15}{24}=0.625=62.5$

Answer is 62.5%
