Step-by-step explanation:
<u>Step 1: Subtract 18 from both sides</u>



<u>Step 2: Divide both sides by 6</u>


Answer: 
Answer:
h ≈ 2.64ft
Step-by-step explanation:
A = 2πrh + 2πr2
h= A
/2πr﹣r = 240
/2·π·5﹣5 ≈ 2.63944ft
Kono Dio Da!!
The expected value of the discrete distribution is of 20.97, hence option C gives the correct answer.
<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>
Hence, according to the table, the expected value is given by:
E(X) = 12 x 0.08 + 18 x 0.15 + 20 x 0.31 + 22 x 0.08 + 24 x 0.15 + 25 x 0.23 = 20.97.
