The correct answer for the exercirse shown in the figure attached is the first option, which is: Calculate the area of the circle A and circle B and calculate the difference.
To calculate the area of the circle A and the circle B, you must apply the formula for calculate the area of a circle, which is shown below:
A=πr²
A is the area of the circle.
r is the radius of the circle.
To calculate the difference, you only have to substract the result of the area of the circle A and the area od the circle B:
At=Aa-Ab
Answer:
88 feet
Step-by-step explanation:
<u>Formula for perimeter of rectangle: 2a + 2b</u>

88
Answer: 88 feet
The frequency of revision times is given by the product of the frequency
density value and the class width.
Correct response:
- The number of students are <u>72 students</u>
<h3>Methods of calculation using a histogram</h3>
The estimate of the number of students who revised for less than 45
minutes is given by the area, <em>A,</em> under the histogram to the left of the 45
minute mark as follows;
Frequency, f = Frequency density × Class width
Number of students = ∑f
Therefore;
A = 5 × 2 + 10 × 2.2 + 20 × 1.6 + 10 × 0.8 = 72
- The number of students that revised for less than 45 minutes = <u>72 </u>students

Answer:
use photo math, take a picture of the equation, go down to the graph and see if there is a plot on (3,-2)
Answer:
66%
Step-by-step explanation:
Use conditional probability.
P(full | holiday) = P(full AND holiday) / P(holiday)
P(full | holiday) = 0.19 / 0.29
P(full | holiday) ≈ 0.66
