If the variance is 28 kg2 what is the standard deviation?

ikadub [295]

Answer:

The standard deviation is 5.29 kg.

Step-by-step explanation:

The standard deviation is the square root of the variance. Mathematically, we have that:

$S(X) = \sqrt{V(X)}$

In this problem, we have that:

$V(X) = 28$

So

$S(X) = \sqrt{V(X)}$

$S(X) = \sqrt{28}$

$S(X) = 5.29$

The standard deviation is 5.29 kg.

A and B are independent events. P(A) = 0.50 P(B) = 0.30 What is P(A/B)? a. not enough information. b. 0.30 c. 0.50 d. 0.15

Gala2k [10]

Answer:

0.50

Step-by-step explanation:

P(A|B)=P(A and B)/P(B) is the formula to find a conditional probability when A and B are not independent.

A and B are independent. This means B has no effect of A. This means P(A|B)=P(A).

P(A|B)=P(A) since A and B are independent

P(A|B)=0.50
