it equals to z/16
brainliest answer plz:)
Students = 380
Adults = 150
You can get this by using x = students and y = adults. Then set up a cost equation of:
3x + 4y = 1740
and a total tickets equation of
x + y = 530
Solve using any method.
Using a discrete distribution, we have that:
a) The expected value is of $250 per policy sold.
b) The expected profit for 10,000 policies is of $2,500,000.
<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>.
Considering that an insurance profit sells for $600, the distribution of the company's earnings is given as follows:
Hence the expected value for a policy sold is given by:
E(X) = 600(0.965) - 4400(0.02) -9400(0.01) - 29400(0.005) = 250.
For 10,000 policies, the expected profit is given by:
E = 10000 x 250 = 2,500,000.
