9 numbers of nickels
13 numbers of quarters
The Answer is a b¹⁰
Simplify the following:
(a^5 b^6 b^4)/a^4
Combine powers. (a^5 b^6 b^4)/a^4 = a^(5 - 4) b^(6 + 4):
a^(5 - 4) b^(6 + 4)
5 - 4 = 1:
a b^(6 + 4)
6 + 4 = 10:
Answer: a b^10
Given
49, 34, and 48 students are selected from the Sophomore, Junior, and Senior classes with 496, 348, and 481 students respectively.
To find:
Which of these types of sampling is used: random, stratified, systematic, cluster, convenience?
Explanation:
It is given that,
49, 34, and 48 students are selected from the Sophomore, Junior, and Senior classes with 496, 348, and 481 students respectively.
That implies,
Since Stratified random sampling is a method of sampling that involves dividing a population into smaller groups–called strata.
Then, the random sampling used is Stratified Random Sampling.
Answer:
We conclude that:
The average rate = -1
Step-by-step explanation:
We need to find the Average Rate of Change from x = -2 to x = 1.
From the table it is clear that:
at x₁ = -2, f(x₁) = 3
at x₂ = 1, f(x₂) = 0
The formula to determine the average rate of change from x = -2 to x = 1.
Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]
= [0 - 3] / [1-(-2)]
= -3 / 3
= -1
Therefore, we conclude that:
The average rate = -1
