Answer:
And rounded up we have that n=31
Step-by-step explanation:
First we need to find the critical value for the margin of error desired. The confidence level is 0.95 so then the significance is 
and the critical value for this case would be:
The margin of error for the proportion interval is given by this formula:
(a)
And on this case we have that 
and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The estimated proportion for this case is 
. And replacing into equation (b) the values from part a we got:
And rounded up we have that n=31
Answer:
1 l 0 0 5 5 5
2 l
3 l 7
4 l
5 l
6 l 5
7 l 0
8 l 68
9 l
Step-by-step explanation:
1 l 0 0 5 5 5 =10,10,15,15,15
And so on.
It is not about 36,000 because
about would be 3,600 or higher
Step-by-step explanation:
quotient is 40 and remainder is 8
Answer:
y = -4x - 4
Step-by-step explanation:
If we have two lines in slope intercept form as
then the product of the slopes 
In other words, 
We have the first line as
The slope of this line is 
The slope of a perpendicular line will be the negative of the reciprocal of this line
Reciprocal of 1/4 is 4
So slope of perpendicular line is -4 which implies
y = -4x + c
We have to determine c
Since the line passes through (-3, 8), plug in these values for x and y in the equation and solve for c
8 = (-4)(-3) + c
8 = 12 + c
c = -4
So the equation of the perpendicular line is y = -4x - 4 (Answer)
It is always a good idea to plot these graphs and see if they fit the data provided
The attached plot shows the two graphs and you can see they are perpendicular to each other and the perpendicular line(the answer) passes through point (-3,8)
