34 = 10 + 4q<br> Solve<br> Need help
LiRa [457]

Simplifying

34 = 10 + 4q

Solving

34 = 10 + 4q

Solving for variable 'q'.

Move all terms containing q to the left, all other terms to the right.

Add '-4q' to each side of the equation.

34 + -4q = 10 + 4q + -4q

Combine like terms: 4q + -4q = 0

34 + -4q = 10 + 0

34 + -4q = 10

Add '-34' to each side of the equation.

34 + -34 + -4q = 10 + -34

Combine like terms: 34 + -34 = 0

0 + -4q = 10 + -34

-4q = 10 + -34

Combine like terms: 10 + -34 = -24

-4q = -24

Divide each side by '-4'.

q = 6

Simplifying

q = 6

Data consistent with summary quantities in the article "Effects of Fast-Food Consumption on Energy Intake and Diet Quality Among
Olegator [25]

Answer:

a) X[bar]₁=  1839.20 cal

b) X[bar]₂= 1779.07 cal

c) S₁= 386.35 cal

Step-by-step explanation:

Hello!

You have two independent samples,

Sample 1: n₁= 15 children that did not eat fast food.

Sample 2: n₂= 15 children that ate fast food.

The study variables are:

X₁: Calorie consumption of a kid that does not eat fast food in one day.

X₂: Calorie consumprion of a kid that eats fast food in one day.

a)

The point estimate of the population mean is the sample mean

X[bar]₁= (∑X₁/n₁) = (27588/15)= 1839.20 cal

b)

X[bar]₂= (∑X₂/n₂)= (26686/15)= 1779.07 cal

c)

To calculate the sample standard deiation, you have to calculate the sample variance first:

S₁²= \frac{1}{n_1-1}[∑X₁² - (( ∑X₁)²/n₁)]= \frac{1}{14} + [52829538 - (\frac{27588^{2} }{15}) = 149263.4571 cal²

S₁= 386.35 cal

I hope it helps!
