Answer:
Step-by-step explanation:
Please find the attachment.
We have been given that a community pool that is shaped like a regular pentagon needs a new cover for the winter months.
To find the area of community pool we will use area of pentagon formula.
, where, a represents the apothem or perpendicular distance from the center of the pentagon and p represents perimeter of pentagon.
Let us find the perimeter of our given pentagon by multiplying each side length by 5.
Now let us find apothem of our pentagon by using Pythagoras theorem.
Upon substituting our given values in above formula we will get,
Therefore, the area of the pool that needs to be covered is 960.42 square feet.
That would be of order 2 answer
Option A
Answer:
y = (C -0.99n)/48
Step-by-step explanation:
Undo what is done to y, in the reverse order. We have y multiplied by 48 then added to 0.99n. So, we must add the opposite of 0.99n and multiply that result by the reciprocal of 48.
C = 48y + 0.99n . . . . . . given
C - 0.99n = 48y . . . . . . add -0.99n
(C -0.99n)/48 = y . . . . . multiply by 1/48
Answer:
According with the graph:
1.) The equation of the regresion line is: y=5,720.10391 x + 957.225810
2.) The values of the correlation coefficient is 0.86
Step-by-step explanation:
In the graph is shown:
1.) Line of Best Fit
y=5720.10391 x + 957.225810
2.) Correlation
.86
