Answer:
f(3) = 26
Step-by-step explanation:
Average rate of change of a function on an interval is;
f(a) - f(b)/(a-b)
Here, we want to find the value of f(-3)
To find the average rate of change on the given interval;
we have;
f(3) - f(-2)/3-(-2) = 17/5
f(3)-9/5 = 17/5
Since denominator is same, we equate numerator;
f(3)-9 = 17
f(3) = 17 + 9
f(3) = 26

Answer:
He performed better in the 800 m race
Step-by-step explanation:
Obtain the standardized score for each event :
Zscore = (score - mean) / standard deviation
1000 meter :
Mean = 4.5 ; Standard deviation = 0.75 ; x = 4.1
Zscore = (4.1 - 4.5) / 0.75
Zscore = - 0.4 / 0.75 = - 0.5333
800 meter :
Mean = 3.2 ; Standard deviation = 0.4 ; x = 3
Zscore = (3 - 3.2) / 0.4
Zscore = - 0.2 / 0.4 = - 0.5
-0.5 > - 0.533
Hence, he performed better in the 800 m race
