Answer:
Rectangle 1 area: 53 units squared
Shape 2 area: 43.75 units squared
Step-by-step explanation:
Shape 1:
We need to find the area of the two triangles in this rectangle and subtract it from the total area of the rectangle.
Total area of the rectangle:
13 * 5 = 65
Area of triangles (they are congruent):
1/2 * 4 * 3 = 6
6 * 2 = 12
65 - 12 = 53
The area of the shaded part is 53 (I don't know what your unit of measurement is. Just say units.)
Shape 2:
First, let's find the area of the parallelogram at the top.
10 * 3 = 30
Now, let's find the area of the rest of the shape. Triangle first...
1/2 * 4 * 1.5 = 3
Now, the rectangle and the tiny triangle we can section out at the end:
7 * 1.5 = 10.5 + 1/4 (Triangle) or 0.25 = 10.75
Total area: 10.75 + 3 + 30 = 43.75
The correct option regarding whether the requirements for a hypothesis test are satisfied is:
D. The conditions are satisfied. The samples are random, and each sample has at least 5 successes and 5 failures.
<h3>What are the conditions for an hypothesis test?</h3>
There are two conditions:
- The samples should be random.
- Each sample should have at least 5 successes and at least 5 failures.
These two conditions are satisfied for this problem, hence, researching this problem on the internet, option D is correct.

Answer:
Give me 5 sters so I will help you any time
Step-by-step explanation:
The area of a circle is given by A=Pi*r^2, and its perimeter, P=2*Pi*r.
To get the radius r, you must divide 452.2 by Pi, and then calculate the square root of this quotient.
To get the circumference or perimeter, use the radius in the formula P=2*Pi*r.
Finally, round the number you get to the nearest tenth.
