Find the perimeter of the figure. If you need to use Pi in your computation, approximate its value as 3.14. Rectangle topped by

Rom4ik [11]

Answer:

74.6 m

Step-by-step explanation:

First look at the rectangle, which is 15 meters wide horizontally and 18 meters long vertically. This rectangle contributes 2(18 m) + 15 m to the perimeter (the 15 m side is the bottom of the figure). That comes to 2(18) m + 15 m, or 51 m.

Next, look at the semicircle. Its diameter is 15 m and thus its total circumference is approximately (3.14)(15 m), or 47.1 m. We take only half of this circumference in calculating the perimeter of this figure: 23.6 m.

The total perimeter of this figure is 23.6 m + 51 m, or approximately 74.6 m.

marin [14]

Answer:

D. Coefficient of Correlation

Step-by-step explanation:

The name itself "Coefficient of Correlation" involves the word correlation, meaning relationship between two things.

The coefficient of Correlation is used to determine how strong a relationship is between two variables.

The formula of Coefficient of Correlation gives a value between -1 and 1. Moreover, it helps to plot a graph showing the strength of relationship.

1 : A strong positive relationship

-1: A Strong negative relationship

0: No relationship at all

One of the most used formula is Pearson Correlation Coefficient Formula, picture of which is attached. X and Y represent two different set of datas.

The other terms are defined as :

Coefficient of Determination : Square of correlation between predicted scores and actual scores. It usually ranges from 0 to 1 .

Standard deviation of estimate : represents the amount of variation among a set of values .

Standard Error of estimate : It is the measure of dispersion of sample means around population means.

(7x-10) (7x+5) (5x+55)

DIA [1.3K]

Answer:

245x^2+2520x^2−2175x−2750

Step-by-step explanation:

=((7x−10)(7x+5))(5x+55)

=((7x−10)(7x+5))(5x)+((7x−10)(7x+5))(55)

=245x^3−175x^2−250x+2695x^2−1925x−2750

=245x^2+2520x^2−2175x−2750

Hope it helps :)
