Answer:
d. We are 95% confident that the proportion of adults (ages 17-26) who attended college is between 53% and 59%.
Step-by-step explanation:
Confidence interval of a proportion p.
We build a confidence interval at the x% level from a sample.
With this, we can say that we are x% sure that the true population propotion is in the interval.
The 95% confidence interval is (0.53, 0.59).
This means that we are 95% sure that the true population proportion is between 0.53 and 0.59.
So the correct answer is:
d. We are 95% confident that the proportion of adults (ages 17-26) who attended college is between 53% and 59%.
The length of AB would be 38 units
<h3>How to determine the length AB?</h3>
The attached image represents the missing piece in the question
Considering the triangle BCD;
Calculate the length BC using the following Pythagoras theorem
BC^2 = CD^2 + BD^2
This gives
BC^2 = 10^2 + 8^2
Evaluate
BC^2 = 164
Considering the triangle CBA;
Calculate the length AB using the following Pythagoras theorem
AB^2 = AC^2 - BC^2
This gives
AB^2 = 40^2 - 164
Evaluate
AB^2 = 1436
Take the square root
AB = 38 (approximated)
Hence, the length of AB would be 38 units

I don’t understand if this is a math problem or a statement.
Answer:
A.) $10,400
Contribution every payday = $60
Pay periods in a year = 26
Step-by-step explanation:
Assume her salary, that is total cost = y
Percentage deduction 15% of total cost
biweekly paychecks = $60
Therefore, 15% of y = $60
(15/100)y = 60
15y = 6000
y = 400
Total value of contribution:
$400 × number of biweeks in a year
If number of weeks in a year = 52
No of bi-weeks = 52/2 = 26
$400 × 26 = $10400
Answer:
growth because 'b' > 1 b decay because 'b' is < 1
