Find the concavity changes of f(x).
Give the x-coordinates.
So, the answer to the multiple choice question is -1 and 5 since those points are where f''(x) changes sign.
Note: You can tell that you're supposed to find the concavity changes of f(x) and not f''(x) because from the graph it's obvious that the concavity of f"(x) doesn't change.
Range for boys = 20-8 = 12
Range for girls = 15-3 = 12
Range is same for both boys and girls.
median of boys = 12.5
median for girls = 6.5
Median is greater for the boys.
Hope it helps!
Answer:
150 miles
Step-by-step explanation:
375 divided by 7.5 is 50
50 time 3 is 150
8 so it would be 2/8 plus 3/8
