Helpppp Find the perimeter

Mathematics
1 answer:
Gwar [14]3 years ago
8 0

The perimeter of rectangle is 16x-2y+4.

Step-by-step explanation:

Given dimensions are;

Length = 5x-y

Width = 3x+2

We know that;

Perimeter of rectangle = 2(Length + Width)

Perimeter of rectangle = 2(5x-y+3x+2)

Perimeter of rectangle = 2(8x-y+2)

Perimeter of rectangle = 16x-2y+4

The perimeter of rectangle is 16x-2y+4.

Which of the following choices is a good estimate for the slope of the Line of Best Fit in the scatter plot?
svetoff [14.1K]

Answer:

A good estimate for the slope is 95/60

Step-by-step explanation:

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

From the graph take the points

(0,0) and (80,125)

substitute

m=\frac{125-0}{80-0}

m=\frac{125}{80}

simplify

m=\frac{25}{16}

Multiply by 3.75 both numerator and denominator

m=\frac{25*3.75}{16*3.75}

m=\frac{93.75}{60}

m=\frac{94}{60}

therefore

A good estimate for the slope is 95/60

Imagine that 30% of all U.S. Households own a dog, P(A)=.3 and that 10% of U.S. households own a Honda vehicle, P(B)=.1. In addi
Ksivusya [100]
P(A|B)= P(B and A) / P(A)

P(B and A) = .3 + .10 = .13 P(A)= .3

So,
P(A|B)= .13/.3

P(A|B)= 0.43333...
