Answer:
And rounded up we have that n=748
Step-by-step explanation:
In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 90% of confidence, our significance level would be given by 
and 
. And the critical value would be given by:
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 best estimatr for the proportionis 0.5 since we don't have any other info provided. And replacing into equation (b) the values from part a we got:
And rounded up we have that n=748
Answer:
A
Step-by-step explanation:
One thing to note is that the side opposite to the angle is taken as perpendicular
If we take 57 as angle then it's opposite side is perpendicular
While if we take 33 as angle x is the perp
Answer:
Step-by-step explanation:
m = -1/3 = Δy/Δx = (2 - 4) / (x - (-1)) = -2/(x + 1)
-1/3 = -2/(x + 1)
-1(x + 1) = 3(-2)
-x - 1 = -6
- x = - 5
x = 5
