Find the probability of each event. A basketball player has a 50% chance of making each free throw. What is the probability that
inna [77]

Hey there! I'm happy to help!

We want to find the probability that the player makes at least seven out of eight free throws. First, we find the probability of them making seven free throws.

\frac{1}{2}^7=\frac{1}{128}

Then, we find the probability of them making eight, which is another possibility that fits this.

\frac{1}{2}^8=\frac{1}{256}

Now, we add the probability of these two events happening.

\frac{1}{128}+\frac{1}{256}=\frac{3}{256}

Therefore, the probability that the player makes at least seven of eight free throws is 3/256 or about 1.17%

Have a wonderful day! :D

The formula for finding the perimeter of a rectangle with length, l, and width, w, is P = 2l + 2w.
user100 [1]
Perimeter of a rectangle:
P=2I+2W=2(I+w)

But if the length and width of a rectangle are both double, then we would have:
Length=2I
width=2w

Therefore, its perimeter would be:
P=2(2I+2w)=4(I+w)

the old perimeter was P=2(I+w) and the new perimeter is P=4(I+w)=2[2(l+w)]
There the perimeter is twice as great.

Answer: C) the perimeter is twice as great.

How to factor (16+2x)(12+2x)=396
morpeh [17]
First, you have to combine all the like terms such as both the 2x’s and 16 and 12 which will give us 28+4x=396. Then you subtract 396 from 28 which is 368. You want the variable x to be alone so you divide 368 by 4 which gives you 92.
