The following table shows the probability distribution for a discrete random variable.

mezya [45]

Answer: C. 30.47

Step-by-step explanation:

The mean of discrete random variable i.e. the expected value of X is given by :-

$E(X)=\sum^{i=n}_{i=1} X_iP(X_i)$

Now by using the given table, the expected value of X is given by :-

$\\\\\Rightarrow\ E(X)=23\cdot (0.16)+25\cdot(0.09)+26\cdot(0.18)+31\cdot(0.12)+34\cdot(0.24)+38\cdot(0.21)\\\\\Rightarrow\ E(X)=30.47$

Hence, the mean of discrete random variable= 30.47

If a sweatshirt is on sale for 35% and now costs $52, <br>what was the original price?

STatiana [176]

The original price was $70.2. (If it’s not supposed to have cents then it’s just $70).

This is because you convert 35% to 1.35. Then, you multiply 52 by 1.35. That’ll give you 70.2.
