Hey there!
In order to calculate the mean you have to add up all up your given numbers (its the average number in total) then divide it by the total numbers you have
Example ⬇
Given: 3, 10, 45
Setting them up (Add) 3 + 10 + 45
Total numbers (Divide) : 3
➡ 3 + 10 + 45 = 58
➡ 58 / 3 = 19.3(repeated of 3)
Good luck on your assignment and enjoy your day!

Answer:1
Step-by-step explanation:
Y=-x^10 Is the correct Answer. D.
Answer:

Step-by-step explanation:
Given equation is
………………(1)
we use derivative formula 


And also apply 'u v' formula

Differentiating equation (1) partially with respective to 'x' , we treated 'y' as constant.
( here y treated as constant so the derivative of constant function is zero in addition but in multiplication the constant is keep as like 'y').
on simplification , we get

again simplification, we get

taking common '
on left on side , we get

dividing '
on both sides, we get

<u>Final answer</u>:-

Answer:
With a .95 probability, the sample size that needs to be taken if the desired margin of error is .04 or less is of at least 216.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
The margin of error:

For this problem, we have that:

95% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
With a .95 probability, the sample size that needs to be taken if the desired margin of error is .04 or less is
We need a sample size of at least n, in which n is found M = 0.04.







With a .95 probability, the sample size that needs to be taken if the desired margin of error is .04 or less is of at least 216.
