Answer:
40%
Step-by-step explanation:
To find the percentage difference between the families with 2 dogs and the families with no dogs, we need to find their difference first.
Difference = 45 - 27
= 18
Now that we know the difference, we just have to put the difference over the total as a fraction and multiply by 100%.
Percentage difference = × 100%
= 40%
Answer:
34
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ 1, 6 ], thus
f(b) = f(6) = 6³ - 9(6) = 216 - 54 = 162
f(a) = f(1) = 1³ - 9(1) = 1 - 9 = - 8
average rate of change = =
= 34
