Well lets go through what I know
- The answer to the first one (A) is 49 and were looking for 45
- Second questions answer (B) is 45 and that's the number were looking for so there's no need to go any further.
So the answer we are looking for is (B) 45
Hope this helps!
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.

Answer:
4/7
Step-by-step explanation:
a positive will cancel out the negative number
Ok....sooo. first. you do a line and number it.
--------------1-------------2-----
as you see the first number in the graph is 1.5 sooo it goes in between number 1 and 2 because its in the middle.
The second is 1.6 sooo this number goes next to 1.6
-------------1--------1.5---1.6-----------------2----------
then you repeat the same with the other.
now idk if this answer the question but i hope someone else makes sure its correct
