I really do not know but I need a point thx
Answer:2
Step-by-step explanation:
The amplitude is the coefficient of sinx, therefore the amplitude is 2
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:
10(2y+2)= 10.2y+10.2
20y+20-y
2(8y-8)=2.8y-2.8
20y+20-y=16y-16
20y-16y-y=-20-16
3y=-36
36/3y=?
y=-12
Step-by-step explanation:
4 cups in a at
12 cups = 3qt
3qt =12 cups
So they are equal
