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.
Then, we find the probability of them making eight, which is another possibility that fits this.
Now, we add the probability of these two events happening.
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
Answer:
28 feet
Step-by-step explanation:
We know that the perimeter of a square is , where l is the length and w is the width.
We also know that the perimeter of a triangle is all of its sides added up.
Since the perimeters will be equal to each other, we can make both of these statements an equation that are equal to each other.
Basically:
We can combine like terms to get a <em>less scary</em><em> </em>equation.
Our goal is to now isolate x so we can find it's value.
Add 2 to both sides:
Subtract 6x from both sides:
Add 10 to both sides:
Divide both sides by 2:
Now we know the value of x, however, our work isn't done. They want to know the perimeter, so we need to substitute x in as 5.
Let's do it on the triangle.
(remember, this is our simplified version of the triangle)
Hope this helped!
