Answer:

y=-x+2

Step-by-step explanation:

The slope-intercept form is y=mx+b where m is the slope and b is the y-intercept.

From the graph, we can see that the y-intercept is at (0,2) so the equation becomes y=mx+2.

Other points on the graph include (1,1) and (2,0). Plugging (1,1) into the slope-intercept equation, we get 1=(m)1+2. Solving this will give us m=-1.

We can confirm this by plugging m=-1 into the equation along with the point (2,0); 0=(-1*2)+2. It checks out!

So our final equation in slope-intercept form will be y=-x+2

A bowl contains 8 chips: 4 blue and 4 red. Three chips are drawn at random and without replacement from a bowl. What is the prob

PIT_PIT [208]

Answer:

the probability that 3 blue chips ( or red chips) are chosen is P(X=3) = 1/14

Step-by-step explanation:

Since the X= choosing x blue chips, then P(X) follows an hypergeometric distribution , when sampling is done without replacement

P(X=x) = (C,x) * (N-C , n-x) /( N ,n)

where ( ) represents combinations then

N= population size = 8 chips

n = sample size = 3 chips

C = number of blue chips = 4 chips

x= number of blue chips that are chosen = 3 blue chips

replacing values

P(X=3) = (4,3) * (8-4 , 3-3) /( 8 ,3) = (4,3) * (4 , 0 ) /( 8 ,3) = 4 * 1 / [ 8!/(3!*5!) ] =

4*3!*5! /8! = 1/14

P(X=3) = 1/14

How many cubic feet will it take to fill the prism below?

stiv31 [10]

Answer:

580

Step-by-step explanation:

I wanted to use the Pythagoras theory but I noted that they've given us the hypotenuse which is 8.6 they have already given us the height is 7 and the base is 5 when you use the Pythagoras theory you'll find that there hypotenuse is 8.6 that's why I wrote forget it there's no need of finding the base and the height for the other triangle just transfer 7 and 5 then calculate the volume I guess I got the answer is 580 hope it helps you good day.

When constructing parallel lines, how can you verify the lines constructed are parallel? Check the intersecting lines with the c

Bond [772]

Answer:

Check the distance between the lines at several places with a compass to ensure they are equidistant.

Step-by-step explanation:

The distance between the parallel lines is always constant and they never intersect with each other.

So, to verify if the lines constructed are parallel, we can check the following:

Check the distance between the lines at several places with a compass to ensure they are equidistant.
