Answer:
And replacing we got:
Step-by-step explanation:
For this case we have the following info given:
represent the sample size selected
represent the population proportion
We want to find the standard error and we can use the distribution for the sample proportion and for this case since the sample size is large enough and we satisfy np>10 and n(1-p) >10 we have:
And the standard error is given;
And replacing we got:
Answer:
A₁ = $150.
Step-by-step explanation:
We know that:
Sarah has saved $150 at the moment.
She wants to double the amount that she saves each month, so the next month she needs to save 2*$150 = $300
And if she saves the $300, then her grandma will give her another $50.
Then, if the previous month Sarah saved A, then the next month she will get the double of A plus $50, which is:
2*A + $50
Then the recursive relation is just:
Where Aₙ is the amount that she saves in the n-th month, and the first term of the sequence is the initial amount that she saved, so we have:
A₁ = $150.

Answer:
The answer is 5
Step-by-step explanation:
I had the test, and what you meant was probably: 1/2(4x-5)+5/2=10
but yes, the answer is 5
