Answer:
2
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is

Here [ a, b ] = [ 0, 2 ], thus
f(b) = f(2) = -(2)² + 4)(2) + 2 = - 4 + 8 + 2 = 6
f(a) = f(0) = 2
average rate of change =
=
= 2

For this case, the first thing we are going to do is add the number of students in each of the disciplines.
We have then:
walk = 9
bike = 8
skateboard = 3
Total: 20
The percentage sought is then:
(3/20) * (100) = 15%
Answer:
percentage of the total students chose skateboarding is:
D.) none of these
Flip the situation:
X + 3.25 = 4.72
Subtract 3.25 from both sides
X + 3.25 - 3.25 = 4.72 - 3.25
X = 1.47
Answer:
The first option is correct.
