Answer:
0.4625 or 46.25%
Step-by-step explanation:
The data for the percentage of contribution and the percentage of numbers from each suburb is presented in the table bellow:
The probability that she gets a donation is given by the sum of the probabilities of getting a donation from each suburb weighed by their respective percentage of numbers of the list:
The probability that she gets a donation is 0.4625 or 46.25%.
Find 75% of 150
First, let's convert 75% to decimal by dividing by 100:
Now, we will multiply 0.75 with 150 to find out answer:
Alright!
To solve, all we need to do is <em>subtract the area of the inner circle from the arear of the outer circle.</em>
But first, we need to find the area of both
Key equation: πr²
π = 3.14
Inner cirle area = π13²
π13² = 530.66
Outer cirle area = π21²
I got 21 by adding 8 and 13: both added together makes the radius of the larger circle
π21² = 1,385.74
Now let's <em>subtract. </em>
1,385.74 - 530.66 = 855.08
The area of the blue is = 855.08 yards²
