Answer:
The height of a puppy to be an adult is about 60 inches tall.
Step-by-step explanation:
Dog's height was predicted as y = 4.5 + 0.7(x1) + 0.55(x2). Given than mother's height(x1) is 40.3in and father's height(x2) is 45.9in, so you can just substitute x1 & x2 value into the equation :
x1 = 40.3in
x2 = 45.9in
y = 4.5 + 0.7(40.3) + 0.55(45.9)
= 4.5 + 28.21 + 25.245
= 57.955in
≈ 60in (3s.f)
Answer:the height of the puppy would be 57.955 inches
Step-by-step explanation:
The equation used to predict how tall a dog will be as an adult is
y =4.5 + 0.7x1 + 0.55x2,
where x1 is the height of the mother and
x2 is the height of the father.
We want to predict the height of a puppy whose mother is 40.3 inches tall and whose father is 45.9 inches tall. We would do this by substituting x1 = 40.3 and x2 = 45.9 into the given equation. It becomes
y =4.5 + 0.7 × 40.3 + 0.55 × 45.9
y = 4.5 + 28.21 + 25.245
y = 57.955 inches
