The answer is $382.80. the perimeter is 600ft. if fence post are placed every five feet, you need 120 post because 600÷5 is 120. each post cost 3.19 so you need 382.80 because 3.19×120 is 382.8
Answer:
Step-by-step explanation:
if solving for y
solve for y by simplifying both sides of equation, then isolating the variable.
y=-3w+10+W
if solving for W
W=3w-10+y
if solving for w
w=W/3 - y/3 + 10/3
Multiply by a across the formula
Answer:
Exact form : <u>10√11</u>
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.
