Angle 2 is 87 degrees bc of alt ext angle converse
Angle 3 93 degrees
Angle 4 is 58 degrees
Answer:
Step-by-step explanation:
2n² + 9n - 35 = (2n-5)(n+7)
n = 2.5, -7
Answer:
We have that 
Step-by-step explanation:
We have just to replace n=10 on the general equation

Therefore:

Answer:
1 1/2= 0.50
2 square root of 2= 1.41
3 3/2 1.5
4 square root of 9= 3
5 square root of 12= 3.464
6 3.56
7 4.03
8 square root of 17= 4.123
9 4.2
10 12
if I get any wrong I'm sorry have a nice day!!
Step-by-step explanation:
Answer: 13300
========================================
Work Shown:
A = event that it rains
B = event that it does not rain
P(A) = 0.30
P(B) = 1-P(A) = 1-0.30 = 0.70
Multiply the attendance figures with their corresponding probabilities
- if it rains, then 7000*P(A) = 7000*0.30 = 2100
- if it doesn't rain, then 16000*P(B) = 16000*0.70 = 11200
Add up the results: 2100+11200 = 13300
This is the expected value. This is basically the average based on the probabilities. The average is more tilted toward the higher end of the spectrum (closer to 16000 than it is to 7000) because there is a higher chance that it does not rain.
