10 points, need these answers filled in!

Ksju [112]

Answer:

Step-by-step explanation:

a) If events A and B are independent we have

P(A/B) =P(A)

But here P(A/B) = 0.8 and P(A)=0.2

Hence A and B are not independent.

b) If events A and B are independent we have

P(A/B) =P(A)

But here P(A/B) = 0.6 and P(A)=0.3

Hence A and B are not independent.

c) If events A and B are independent we have

P(A/B) =P(A)

Jere P(A/B) = 0.5 and P(A)=0.5

Hence A and B are independent.

Box A has a surface area of 98 in 2. If box B is 4 times the size of box A, what is the surface area of box B?

Ksju [112]

Given:

Box A has a surface area of 98 in².

Box B is 4 times the size of box A.

To find:

The surface area of box B.

Solution:

Let "a" be the side of box A , then "4a" be the side of box B because box B is 4 times the size of box A.

We know that the areas of similar figures are proportional to the square of their corresponding sides.

$\dfrac{\text{Area of box A}}{\text{Area of box B}}=\dfrac{(\text{Side of box A})^2}{(\text{Side of box B})^2}$

$\dfrac{98}{A_B}=\dfrac{(a)^2}{(4a)^2}$

$\dfrac{98}{A_B}=\dfrac{(a)^2}{16a^2}$

$\dfrac{98}{A_B}=\dfrac{1}{16}$

Using cross multiplication, we get

$98\times 16=1\times A_B$

$1568=A_B$

Therefore, the surface area of box B is 1568 in².
