Answer:

9C6 / 25C6 = 84/177100

Step-by-step explanation:

Here 9 mid sized

16 compact cars

selected = 6

9C6 / 25C6 = 84/177100

for  3 mid sized

3 compact cars

then

3Cx/9Cx

divide by 3 we get

Cx/3Cxtaking Cx coomon

it become Cx =1/3 hence the probability is 1/3

Rebecca bought candy boxes in the shape of a square pyramid to use for party favors. The side length of each box is 3.6 inches,
diamong [38]

Answer:

Yes maybe.

Step-by-step explanation:

Well basically if we find the volume of 20 pieces of candy in all, that would be= 20*0.8= 16 cu.inches

And then if we find the volume of the square based pyramid, that would certainly be= 3.6*3.6*4 that is 51.84

Then lastly, if we do, 51.84 ÷16 the final answer will be 3.24. Which might actually be the answer as the pieces of candy certainly can't pass the limit 20 according to me.

What is the x value and y value of the point of intersection of y = -3x + 10 and y = 2x - 5?
kakasveta [241]
So you can use substitution...which is where you have Y all alone on one side of your equation and then plug it in to the other equation...2x-5=-3x+10 and you.solve for X. So x= 3. Then plug 3 into one of the original equations... Y=2(3)+5. So Y= 11.

Explanation:

Take 72 from 180.

180 - 72 = 108.

Since there are two y's AND they're congruent, divide 108 by two and get 54.
