Step-by-step explanation:
Here, since the age of the crab is given in months and the regression line was computed using the age in months, we just have to replace the value of the age in the formula to estimate the size.
The formula obtained for the estimated size Y was
Y = 9.1411 + 0.4775X
where X is the age in months
Replacing X with 23.2417, we get
Y = 9.1411 + 0.4775*23.2417 = 20.24 cm
The hypotenuse is always opposite the right angle and it is always the longest side of the triangle. You are trying to find the Hypotenuse.
4*4 + 3*3 = x
16 + 9 = 25
25 divide by 2
= 5
X=5
