IS THERE LIFE ON MARS? A random sample of 160 scientists is asked whether they believe that life once existed on Mars. Eight of

them do, and 152 do not. If the true proportion of scientists who believe life once existed on Mars is 5%, what is the probability of eight or fewer answering "yes" in a sample of this size? What sampling distribution(s) can we use to compute this probability?

A) choose the linear model that passes through the most data points on the scatterplot.
irina1246 [14]
Answer: b

Explanation:
The line of best fit to a scattergram is obtained in linear regression analysis by minimizing the sum of the squared errors.
For example, in the diagram shown below, there are n data points in the scattergram.
The error for the i-th data point is e_{i}.
The coefficients (a and b) for the line of best fit are determined using calculus, to minimize \sum_{i=1}^{n} e_{i}^{2}.

Find the number to sides of a regular polygon if the sum of the interior angles are 7560
Stels [109]
Use S=(n-2)180 
S is the sum and N is the number of sides
If you know that the sum is 7560 then plug that in for S
7560=(n-2)180
Then solve for n
7560=180n-360 (note I used distributive property)
7560+360=180n
7920=180n
7920/180=n
n=44 sides
I hope this helps :)

X - y = 3<br> x + 3y = 9
Ugo [173]
Solve for one of the variables in the first equation (in this case, I will solve for X):
X = Y + 3

Then use that value of X in the second equation to solve for Y:
X + 3Y = 9
(Y + 3) + 3Y = 9
4Y + 3 = 9
4Y = 6
Y = 1.5

Use the value of Y we just found in the X equation we created:
X = Y + 3
X = 1.5 + 3
X = 4.5

Therefore X = 4.5 or 9/2 and Y = 1.5 or 3/2.
