The administration at a community college wants to estimate the number of parking spaces they will need next year. they survey 80 students; 75 of the students in the sample drive to campus by themselves each day. which of the following is a reason the administration should not calculate a confidence interval for the proportion of all students who drive to campus? check all that apply. group of answer choices the sample needs to be random but we don’t know if it is. the actual count of drivers is too small. the actual count of those who do not drive to campus is too small. n(p‐hat) is not greater than 10. n(1 minus p‑hat) is not greater tha

step-by-step explanation:

8*8*8*8*8*8*8*8*8*8*8*8=68719476736

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3
