The diameter of the moon is about 3500 km. Approximate the surface area of the moon using the formula for the surface area of a

horrorfan [7]

Answer:

$3.8465 *10^7$ square kilometers

Step-by-step explanation:

The surface area of a sphere can be found using the formula $SA=4\pi r^2$ . Since the diameter is 3500 km then its radius is half of this. 3500 divided in two is 1,750 units. Substitute r=1,750.

$SA=4\pi r^2\\SA = 4 \pi (1750)^2\\SA = 4 \pi *3,062,500\\SA =38,465,000$

The surface area of the moon is about 38,465,000 square kilometers. Write this is scientific notation using base. $3.8465 *10^7$

A and B are two events. Let P(A)=0.5 , P(B)=0.9 and P(A and B)=0.15 .

Nana76 [90]

Answer:

option-C

Step-by-step explanation:

we are given

Let P(A)=0.5

P(B)=0.9

P(A and B)=0.15

we know that

$P(A|B)=\frac{P(Aand B)}{P(B)}$

now, we can plug values

$P(A|B)=\frac{0.15}{0.9}$

$P(A|B)=0.16666$

but we have

P(A)=0.5

we can see that both are not equal

$P(A|B)\neq P(A)$

so, A and B are not independent

so, option-C........Answer
