Answer:
15 maybe?
Step-by-step explanation:
42 - 14 = 28
18 - 5 = 13
28 - 13 = 15
subtract the 14 because it says it is in neither.
Subtract 5 from 18 because 18 are in math and only 5 are in both math and science.
Subtract 13 from the 28 because those 13 are in math and wont be in science also.
For this question you have to find how many heartbeats are in 1 minute.
So if you divide 210 by 3 you get 70

Answer:
Option A is correct.
y = 35.4 bushels per acre when rainfall = 7.1 inches
Step-by-step explanation:
An image of the steps to obtain the equation that relates x to y is attached to this answer.
n = number of variables = 9
μₓ = mean of variable x (rainfall in inches)
μᵧ = mean of variable y (yield in bushels per acre)
σₓ = standard deviation of variable x (rainfall in inches)
σᵧ = standard deviation of variable y (yield in bushels per acre)
y = 4.379x + 4.268
when x = 7.1
y = 4.379(7.1) + 4.268 = 35.3589 = 35.4 bushels per acre.
