Answer:
The equation relates the variables is y = 8x ⇒ D
Step-by-step explanation:
If x and y vary directly (y ∝ x), then y = k x, where
- k is the constant of variation
- k can be found using the initial value of x and y
∵ The variable x and y vary directly
∴ y ∝ x
→ By using the rule above
∴ y = k x
∵ y = 40 when x = 5
∴ The initial values of x and y are x = 5 and y = 40
→ Substitute them in the equation above to find k
∵ 40 = k(5)
∴ 40 = 5k
→ Divide both sides by 5
∵ 
= 
∴ 8 = k
→ Substitute the value of k in the equation above
∴ y = 8x
∴ The equation relates the variables is y = 8x

Answer:
D.
Width = 11 yards
Length = 15 yards
Step-by-step explanation:
P = 2(l + w)
Consider the width to be x.
The length would then be x+4.
We know that P = 52 yd
52 = 2(x + x + 4)
52 = 2(2x + 4)
52 = 4x + 8 (Subtract 8 from both sides)
44 = 4x (Divide both sides by 4)
x = 11
The width is x, so the width is 11 yards.
The length is x+4, so the length is 15 yards.
Answer:
A. A binomial distribution with n=25 and p=0.58
Step-by-step explanation:
We're looking at the number of tails, not the proportion. The probability of tails is 0.58, and the number of tosses is 25.
