Answer:
A is the answer
12 in
first substitute the variables
then 78=1/2h(5 + 8)
this makes it an equation
add similar terms which equals to
78=1/2xhx13
then divide both sides by 13
6=1/2xh
lastly divide both sides by 1/2
12=h
Step-by-step explanation:
proof
A=1/2x12(5 + 8) then
A=1/2x12x13 then
A=6x13 then
A= 78in^2
Considering the given discrete probability distribution, it is found that the expected share is of 10%.
<h3>What is the mean of a discrete distribution?</h3>
The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
In this problem, the distribution is given by:
Hence the expected value is given by:
E(X) = 0.2 x 0.05 + 0.6 x 0.1 + 0.2 x 0.15 = 0.1 = 10%.
The expected share is of 10%.

Hey!!
here is your answer >>>
Let's take the total amount as 'X'
Then,
(40/100)X = 24
2x /5 = 24
x = (24*5)/2
x = 12*5
x = 60!.
100% is 60
Hope my answer helps!
If the question is 5m^2 the answer is 80. And if the question is 5m2 then it is 40
