<h3>
Answer: 69.1 cm</h3>
Work Shown:
C = 2*pi*r
C = 2*3.14*11
C = 69.08
C = 69.1
This is the approximate distance around the circle, aka the perimeter.
Answer:
24 square feet
Step-by-step explanation:
To find the amount of square feet, find the area, using the formula A = lw
Plug in the length and width:
A = lw
A = (4)(6)
A = 24
So, the quilt is 24 square feet
I made $120 a week. How much money would I be able to make in 75 weeks?
120 x 75 = 1040
I would make $1040 in 75 weeks.
Hope this was ok enough. :)
Using the z-distribution, the estimate for how much the drug will lower a typical patient's systolic blood pressure is:
<h3>What is a z-distribution confidence interval?</h3>
The confidence interval is:
In which:
- is the sample mean.
- is the standard deviation for the population.
In this problem, we have a 80% confidence level, hence, z is the value of Z that has a p-value of , so the critical value is z = 1.28.
The other parameters are given by:
Then the bounds of the interval are:
Hence the interval is:

Answer:
For the one including 4w the answer is - 7
The one with n/2 is - 12
Step-by-step explanation:
4w=-13-15
4w=-28
w=-7
Multiply by 2 on both sides
-24=n-12
-24+12=n
Always write it in the variables perspective.
n=-12
