Answer: how about 90
Step-by-step explanation:
Its a 360 if you multiply 90×4 you get 360 every side is 90 degrees
Answer:
The upper limit of a 95% confidence interval for the population mean would equal 83.805.
Step-by-step explanation:
The standard deviation is the square root of the variance. Since the variance is 25, the sample's standard deviation is 5.
We have the sample standard deviation, not the population, so we use the t-distribution to solve this question.
T interval:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 15 - 1 = 14
Now, we have to find a value of T, which is found looking at the t table, with 14 degrees of freedom(y-axis) and a confidence level of 0.95(
). So we have T = 1.761
The margin of error is:
M = T*s = 1.761*5 = 8.805.
The upper end of the interval is the sample mean added to M. So it is 75 + 8.805 = 83.805.
The upper limit of a 95% confidence interval for the population mean would equal 83.805.
3/(3 - 12i)
To simplify this, multiply both sides by (3 + 12i)
(3 - 12i)(3 + 12i)
<em><u>Distributive property.</u></em>
3(3 + 12i) - 12i(3 + 12i)
9 + 36i - 36i - 144i^2
<em><u>Simplify.</u></em>
9 - 144i^2
i^2 can be interpreted as -1.
9 + 144
<em><u>Combine like terms.</u></em>
153 is the simplified version of the bottom half of the expression.
Now for the top half.
3(3 + 12i)
<em><u>Distributive property.</u></em>
9 + 36i
We can simplify this further by factoring.
3(3 + 12i)/153
1 + 4i/17
1/17 + 4i/17 is the simplified version of the expression. (This is your answer.)
Let me know if you have any other questions.
1 Gallon is equal to 4 Quarts.

Quarts is equal to 10 Cups.

There are 7 Cups left.
7 Cups is equal to 56 Fluid Ounces.
Therefore, the answer is B.
