Using it's formula, it is found that the mean of the discrete random variable is given by:
B. 30.47.
<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, considering the table, the mean of the discrete distribution is:
E(X) = 23 x 0.16 + 25 x 0.09 + 26 x 0.18 + 31 x 0.12 + 34 x 0.24 + 38 x 0.21 = 30.47.
Hence option B is correct.

Answer:
Line A overlaps line B
Step-by-step explanation:
find gradient of both A and B and use it to find the equation of both lines
final answer will reveal that both lines are the same implying that one overlaps the other
Answer:
Step-by-step explanation:
(-13-12)/(-2-3)= -25/-5= 5
y - 12 = 5(x - 3)
y - 12 = 5x - 15
y = 5x - 3

Find Monthly Income
----------------------------------------
Gross Annually Income = $43 908
Gross Monthly Income = $43 908 ÷ 12
Gross Monthly Income = $3659
----------------------------------------
Paycheck deducted for 401k
----------------------------------------
6% of $3659
= 0.06 x 3659
= $219.54
----------------------------------------
Employer contribution to his 401k
----------------------------------------
4% of $2659
= 0.04 x 3659
= $146.36
----------------------------------------
Total contribution to his 401k
----------------------------------------
$219.54 + $146.36 = $365.90
----------------------------------------
Answer: $365.90 (Answer C)
