If 6 goes to 12, if it remains proportional, it should be x2. So 8 x 2 = 16. X = 16

Below are the data collected from two random samples of 500 American adults on the number of hours they spend doing leisure and

ElenaW [278]

From the question we are told that:

Total Sample size n=500

Dan's mean \=x_D= 3hr

Bret's mean \=x_D= 4hr

Generally, the Total hours spent doing leisure and sports activities is mathematically given by

For Sample A

$T_a=(1*70)+(2*90)+(3*135)+(4*140)+(5*65)\\\\$

$T_a=1540 hours$

For Sample B

$T_b=(1*80)+(2*80)+(3*130)+(4*135)+(5*75)$

$T_b=1545$

Therefore

Average Time spent doing leisure and sports activities by an American Adult

For Sample A

$T_A=\frac{T_a}{n}$

$T_A=\frac{1540}{500}$

$T_A=3.08$

$T_A \approx 3$

For Sample B

$T_A'=\frac{T_b}{n}$

$T_A'=\frac{1545}{500}$

$T_A'=3.09$

$T_A' \approx 3$

Therefore

Dan is Correct because 3.08 or 3.09 is approximately equal to 3

Slav-nsk [51]

4d = 24 would be the right equation. To double check you would divide both sides by 4 (the number of legs) to find the amount of dogs.

Divide both by a number that can go into both terms so it will be 5 .
$\frac{5c-15}{5}$ which is 5(c-3)
