Answer 1

A.11

Step-by-step explanation:

Here apply the interpolation formula to find the value of y

From the table, you can interpolate the value of y where x is 92 by using the points (91,10) and (98,15)

The formula to apply is;

$y-y_1=\frac{y_2-y_1}{x_2-x_1} *(x-x_1)$

where

(x₁,y₁)=(91,10)

(x₂,y₂)=(98,15)

(x,y)=(92,?)

Substitute values in the equation;

$y-10=\frac{15-10}{98-91} *(92-91)\\\\y-10=\frac{5}{7} *(1)\\\\7(y-10)=5\\7y-70=5\\7y=5+70\\\\7y=75\\\\y=75/7=10.71\\\\y=11$
