1 lb = $2.50
3.5 lbs = $x
3.5 x 2.50 = x
3.5 x 2.5 = $8.75

Step-by-step explanation:
Plugging it in the slope formula we get -6+6 = 0, meaning the division will be 0. This the slope is 0
Answer:
The 99% confidence interval for the fraction of U.S. adult Twitter users who get some news on Twitter is between 49.34% and 60.66%, which means that we are 99% sure that the true percentage of US adult Twitter users who get some news is in this interval.
Step-by-step explanation:
Confidence interval:
A confidence interval has the following format:
In which M is the sample mean, z is related to the confidence level and s is the standard error.
55% of U.S. adult Twitter users get at least some news on Twitter (Pew, 2013). The standard error for this estimate was 2.2%.
This means that
99% confidence level
So , z is the value of Z that has a pvalue of , so .
Lower bound of the interval:
Upper bound:
The 99% confidence interval for the fraction of U.S. adult Twitter users who get some news on Twitter is between 49.34% and 60.66%, which means that we are 99% sure that the true percentage of US adult Twitter users who get some news is in this interval.
Answer:
The answer to your question is: 228 in²
Step-by-step explanation:
Data
length = 8 in
Wide = 6 in
height = 6 in
Total area = ?
Formula
Area = base x height
There are 3 kinds of rectangles
1st rectangle
Area = 8 x 6
= 48 in² x 2 = 96 in²
2nd
Area = 8 x 6
= 48 in² x 2 = 96 in²
3rd
Area = 6 x 6
= 36 in²
Total area = 96 + 96 + 36
= 228 in²
