Find each missing length to the nearest tenth.​

8.944

Step-by-step explanation:

To find the missing Length, Use Pythagorean Theorem!

so it is approximately 10 but not quiet

hope this helps

To begin with, there are few values that we need to work out first. We need:
∑xy ⇒ in words, multiply each pair of value x and y, then add the answers)
∑x² ⇒ in words, square each value of x, then add the answers)
∑x ⇒ in words, add all values of x
∑y ⇒ in words, add all values of y

in total, we have 16 pairs of data, so we have n=16

∑xy = 10466
∑x² = 120207
∑x = 1379
∑y = 120

The regression equation is given by , where
and a=(mean of y)+b(mean of x)

∑xy-(∑x∑y)/n

∑x²-((∑x)²/n)

then

Mean of x = ∑x/n = 1379/16 = 86.1875
Mean of y = ∑y/n = 120/16 = 7.5

Hence the equation is
