A landscape architect used the entire length of an 80-foot rope to lay out a flower bed in the shape of a square. In another area, he used the entire
length of the same rope to lay out a second flower bed in the shape of a circle. (Drawings not to scale.)
Exhit
Perimeter 80 feet
Circumference - 80 feet
What is the area of the circle?
A 125.6 ft2
B. 2,041.8 ft2
c. 215.2 ft
D. 506.5 ft2
The area of the circle with a perimeter of 80 feet is 509.31 square feet.
The entire length of the rope = 80 feet
So, the perimeter of the flower bed = 80 feet
Since the flower bed is in a square shape
So, the perimeter of the square = The entire length of the rope
The perimeter of the square = 80 feet
Suppose the side of the square is a
So, 4a = 80
a =20
So, the area of the square = 20² = 400 square feet.
What is the area of a circle?The area of a circle with a radius r is πr².
Similarly, when the flower bed is in a circular shape
The perimeter of the circle = 80
Suppose the radius of the circle is r
So, [tex]2\pi r =80\\\\[/tex]
[tex]r= 12.73 feet[/tex]
Area of circle = [tex]\pi r^{2}[/tex]
Area of circle = 509.31 square feet.
Therefore, the area of the circle with a perimeter of 80 feet is 509.31 square feet.

The measures of two angles are represented by the expressions (5x + 24)° and (9x − 17)°. If the two angles are equal, what is the value of x?
Answer:
x=10.25
Step-by-step explanation:
Angle 1 = (5x+24)°
Angle 2 = (9x-17)°
The two angles are equal. It means,
(5x+24)°=(9x-17)°
Taking like terms together,
5x-9x=-17-24
-4x=-41°
Dividing each side by -4
x=10.25°
So, the value of x is 10.25.

50 POINTS WILL GIVE BRAINLIEST Use the drawing tools to form the correct answer on the grid. Caroline is planting flowers in her garden. She plants her first 7 flowers in 4 minutes. After 12 minutes, she has planted 21 different flowers. Plot four data points and the line of best fit to model how long it takes Caroline to plant flowers.
Answer:
(4, 7)(12, 21)(7, 12.25)(21, 36.75)Step-by-step explanation:
The y axis shows the number of flowers planted.
The x axis shows the number of time that passes in minute.
She plants her first 7 flowers in 4 minutes.
7 represents the number of flowers planted so that will be the y coordinate.
4 minutes represents the number of time that passes so that will be the x coordinate.
(4, 7) will be the first point.
After 12 minutes, she has planted 21 different flowers.
12 minutes represents the number of time that passes so that will be the x coordinate.
21 represents the number of flowers planted so that will be the y coordinate.
(12, 21) will be the second point.
We can find the unit rate that she plants flowers in.
7 / 4 = 1.75 flowers per minute
21 / 12 = 1.75 flowers per minute.
If we divide or multiply this value to the x and y coordinates, we can find new points.
Lets multiply 1.75 to (4, 7)
(4 * 1.75, 7 * 1.75)
(7, 12.25)
Lets multiply 1.75 to (12, 21)
(12 * 1.75, 21 * 1.75)
(21, 36.75)
Best of Luck!

Explain why the formulas for sample variance and population variance are different.
A. Variance is defined as the mean deviation, and, for a population, is computed as the sum of deviations divided by N. The sample variance will be biased and will consistently underestimate the corresponding population value.
B. Variance is defined as the mean squared deviation, and, for a population, is computed as the sum of squared deviations divided by N. The sample variance will be biased and will consistently underestimate the corresponding population value.
C. Variance is defined as the mean squared deviation, and, for a population, is computed as the sum of deviations divided by N. The sample variance will be biased and will consistently underestimate the corresponding population value.
Answer:
The answer is "option C".
Step-by-step explanation:
Distinctions are also the mean squared variance just are calculated as the number of standard differences divided by "N" and for a population. After all, if a sample uses this very same definition.
Its standard deviation would become partially skewed as well as the resulting community value becomes continuously underestimate. Its experimented formula consequently includes a correction modification for a bias. Its modification involves dividing by instead of n.Answer:
