Sameera predicted that she would sell 38 blankets, but she actually sold 28 blankets. which expression would find the percent error? use the table below to answer the question. percent error item approximate value exact value error absolute error ratio percent error blankets 38 28 10 10

c

Step-by-step explanation:

Solution: We are given:

Predicted Sales by Sameera

Actual Sales by Sameera

Now to find the Percent error, we have to use the below formula:

Therefore, the percent error is      

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
