Answer:
9
Step-by-step explanation:
The factors of 9 are: 1, 3, 9
The factors of 45 are: 1, 3, 5, 9, 15, 45
Then the greatest common factor is 9.
= 2+2+7+10 = 21 . Hope this helps and answers your question! :) :D
Answer:
10z - 24y
Step-by-step explanation:
4z + 3(2z - 8y)
first distribute
4z + 6z - 24y
then combine like terms
10z - 24y
Answer:
Point estimate: 0.391
Margin of error: 0.042
Step-by-step explanation:
A confidence interval has two bounds, a lower bound and an upper bound.
A confidence interval is symmetric, which means that the point estimate used is the mid point between these two bounds, that is, the mean of the two bounds.
The margin of error is the absolute difference between these bounds and the point estimate.
In this question:
Lower bound: 0.349
Upper bound: 0.433
Point estimate: (0.349 + 0.433)/2 = 0.391
Margin of error: |0.349 - 0.391| = |0.433 - 0.391| = 0.042
