Lus Payton thought the mix would make 36
cookies, but it only made 28. What was
her percent error?
Round to the nearest percent .

Percent error=29%

Step-by-step explanation:

Percent error=(Estimated value-Actual value/ Actual value) × 100

Estimated value = amount of cookies Payton thought the mix could make = 36

Actual Value= Amount of cookies made= 28

Percent error= (36- 28)/ 28 x 100

=8/28 x 100

=0.2857 x 100

=28.57 rounded to 29%

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
