Area of the small circle = \pirx^{2} = 3.14 x 7x^{2}= 153.86

Area of the big circle = \piRx^{2}=3.14 x 14x^{2}= 615.44

The shaded area = area of the big circle - area of 2 small circle = 615.44-2x153.84≅308

The answer is 308

So the small circles are touching each other and they have a radius of 7 inches. so that means that the big circle will have a radius of 14 inches which is double the small circles radius. after we find the radius of the big circle, we have to calculate the big circles area. which we will find by the formula

14 \times 14 \times \pi
14 squared times pi is 615.44
this is the big circles are but the question askes the area left after we subtract the 2 small circles
we find the are of the small circles by doing
7 \times 7 \times \pi
which is 153.86.
after finding the area of the small circles we multiply it by two a d subtract it from the big circles area
615.44 - 153.86 \times 2

and we find 307.72 which is the closest to 308
so the answer is D

Part 1: Multiple Choice
Keith_Richards [23]

Option C: (0,125) is the y - intercept.

Explanation:

The given function is f(x)=x^3-5x^2-25x+125

We need to determine the y - intercept.

<u>The value of y - intercept:</u>

The y - intercept is the value of y when x = 0

The y - intercept of the function can be determined by substituting x = 0 in the function.

Hence, let us substitute x = 0 in the function f(x)=x^3-5x^2-25x+125, we have,

f(x)=(0)^3-5(0)^2-25(0)+125

Simplifying the terms, we get;

f(x)=0-5(0)-25(0)+125

f(x)=0-0-0+125

f(x)=125

Thus, the value of y is 125.

Hence, the y - intercept is 125.

Therefore, the coordinates of the y - intercept are (0,125)

Hence, Option C is the correct answer.

Two fair dice are rolled 3 times and the sum of the numbers that come up is recorded. Find the probability of these events. a. T
alexandr402 [8]

Answer:

Step-by-step explanation:

Given that two fair dice are rolled 3 times and the sum of the numbers that come up is recorded.

a) The sum is 4 on each of the three rolls.

(1,3) (2,2) (3,1) HEnce for one throw prob = 3/36 =1/12

Prob for getting same sum 4 in 3 rolls = (\frac{1}{12} )^3

(since each trial is independent)

b) Prob sum =4 in exactly 2 rolls

= 3C2 (1/12)^2 (11/12)=\frac{33}{12^3}
