The perimeter of the triangle shown are equal. Find the side lengths of each triangle.

Lunna [17]

Good morning ☕️

___________________

Step-by-step explanation:

Let p1 be the perimeter of triangle ABC

p2 be the perimeter of triangle PQR

p1=(2x+4)+(2x+3)+(2x) = 6x+7

p2=(2x)+(2x)+(3x+1) = 7x+1

p1=p2 ⇔ 6x+7=7x+1 ⇔ 7x-6x=7-1 ⇔x=6

Then :

AC=2(6)=12

AB=2(6)+4=16

BC=2(6)+3=15

PQ=12

QR=12

PR=3(6)+1=19.

In a statistics course, a linear regression equation was computed to predict the final exam score from score on the midterm exam

Bingel [31]

Answer: c. 91

Step-by-step explanation:

Given : A linear regression equation was computed to predict the final exam score from score on the midterm exam.

The equation of the least squares regression line was

$Y = 10 + 0.9x$

, where y= the final exam score

x= the midterm exam score.

if Joe score a 90 on the midterm exam, the put x= 90 in the above eqaution , we get

$Y = 10 + 0.9(90)$

$\Rightarrow\ Y = 10 + 81=91$

Hence, the predicted value of his score on the final exam would be 91.

Therefore , the correct answer is c. 91 .
