Answer:
The answer is 3x-27
Step-by-step explanation:
If the angles are vertical from each other it means they are congruent. 2x+30 is 63, you plug in the x, 2(30)+30. You do that to the second one and also get 63, 3(30)-27. Therefore 3x-21 is the answer.
Put all numbers in smallest to largest order
if there are an odd number of results, the median is in the middle
if there even, then its the mean of the two central numbers
If you mean h(4)
h(4)=(4)*2 -5(4)
=8-20
=-12
The answer will be-12
Answer: The answer choice on the left, AKA the first one.
Step-by-step explanation:
Answer:
57.5
Step-by-step explanation:
The expected frequency of West Campus and Failed :
Let :
Failed = F
East Campus = C
West Campus = W
Passed = P
Frequency of FnW :
[(FnE) + (FnW) * (PnW) + (FnW)] / total samples
[(52 + 63) * (63 + 37)] / 200
[(115 * 100)] / 200
11500 / 200
= 57.5
n(Failed n East campus)
