A line that passes through the points (−5, 7) (10, 1). Using the mx+b format

lianna [129]

Answer:

y=2x-19

Step-by-step explanation:

I'm guessing you mean slope intercept form y=mx+b

If so, first you would have to find the slope of the line

To do that, use the formula y2-y1/x2-x1

Remember you can pick any coordinate pair for this

I will pick 1=y2 -5=y1 10=x2 and 7=x1

When I put that in the equation I get 1-(-5)/10-7

Overall I get 6/3, or 2

Now to find the y intercept, you plug in the slope and one of the coordinates(any is fine)

I will pick (10,1)

1=y and 10=x and 2=m

1=2(10)+b

this simplifies to 1=20+b

now subtract 20 from both sides and get -19 = b

Now you have your equation y=2x-19

There are currently 18 pit bulls at the pound. Of the 18 pit bulls, four have attacked another dog in the last year. Joe, a memb

laila [671]

Answer: 0.7748

Step-by-step explanation:

Given : Number of bit bulls at the pound = 18

Number of pit bulls have attacked another dog in the last year =4

The proportion of pit bulls have attacked another dog in the last year: $p=\dfrac{4}{18}\approx0.22$

Number of the pit bulls selected = 6

The probability of that none of the pit bulls in Joe's group attacked another dog last year : $P(0)=(1-0.22)^6=0.225199600704\approx0.2252$

By using binomial , the probability that at least one of the pit bulls in Joe's group attacked another dog last year is given by :-

$P(x\geq 1)=1-P(x$

Hence, the required probability = 0.7748

Find the exact area of the shaded please helppp ILL GIVE BRAINLIESTTTTTT

musickatia [10]

Answer:

The exact area is $5\pi$

Step-by-step explanation:

The area of the major circle is subtracted from the area of the minor circle (blank)

Major circle

$r=\frac{6}{2} =3$

$A=\pi r^{2} =\pi (3)^{2} =\pi (9)=9\pi$

Minor circle:

$r=\frac{4}{2} =2$

$A=\pi r^{2} =\pi (2)^{2} =\pi (4)=4\pi$

The shaded area:

$9\pi -4\pi =5\pi$

Hope this helps
