Answer:
z=12
Step-by-step explanation:
5+7=12
A) 2L + 2W = 152B) L = W + 28We substitute equation B) into A)A) 2 * (W + 28) + 2W = 152A) 2W + 56 + 2W = 152A) 4W = 96A) Width = 24 feet
Length = 52 feet
-2m + 4 = 10
-2m = 6
m=-3
M would be -3
For the probability of rain on julty 4h of 0.5 his expected profit is 8885.5 dollars.
<h3>What is probability?</h3>
The probability is occurrence of a certain event out of the total number f events that can happen.
Given in the question the probability of rain is 0.5 therefore the probability of not raining is also 0.5.
If it does not rain he makes a profit of 30427 dollars and if it rains he suffers a loss of 12656 dollars.
We know, the expected profit is,
= 0.5(30427) - 0.5(12656).
= 15213.5 - 6328.
= 8885.5 dollars.
