Answer: 
Step-by-step explanation:
Given: Sample size: n = 41
Sample mean
degrees
Population standard deviation
degrees
Confidence level (c) = 80% =0.80
Significance level (a) = 1- c = 1-0.80 = 0.20
z-score for 80% confidence level : z = 1.2816 [from z-table]
Confidence level for population mean :-







Hence, 80% confidence interval for the temperatures in the freezer 
Answer: x = 8
Step-by-step explanation:
Hello again XD.
This is a coordinate plane and all the angles on a coordinate plane add up to 360°
Divide 360 by 4 to get the measurement of the section we are working in.
360/4 = 90°
This means it is complementary and complementary angles state that both separate angles added together = 90°
therefore,
6x + 2 + 40 = 90
combine like terms:
6x + 42 = 90
now subtract 42 from both sides
6x = 48
divide 6 from both sides to get:
x = 8
Let me know if you have any more questions you want answered and I hope I explained this well.
6, 9, 9, 12, 18, 24, 24, 24, 37
37-6= 31
Answer:
Diverges
Step-by-step explanation:
We can solve this by using integral by parts:
Let



We can add
to both sides

We can evaluate the limit between 2 and infinity.
If x tends to infinity the limit will be infinity and therefore the integral diverges to ∞
