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

Answer:

The 2nd choice ( the one that starts with square root of 5 )

Step-by-step explanation:

I turned all of the choices into decimals so they had the same playing field then I put them from least to greatest and I got square root of five, 5/2, 2.717171717171, 2 and 3/4.

What is the ultimate goal when solving equations? What do you want your final answer to look like?
STALIN [3.7K]

Answer:

\huge\boxed{\text{To get x on one side of the equation:} \ \ x = ...}

Step-by-step explanation:

When we solve for an equation, our goal is to find the value of the variable. Any variable can be used, but for the time being let’s assume we use x.

We can algebraeically solve equations until we get the value of x - in which we will have x equal to something.

Say we have the equation 5x+5=20. Our goal is to find the value of x. <u>We can do this by getting x isolated on one side so we have something equal to x</u>.

We can subtract 5 from both sides and divide both sides by 5.

5x=15\\\\x=3

We now know the value of x since it’s on one side of the equation.

Hope this helped!

The athletic departments at 10 randomly selected U.S. universities were asked by the Equal Employment Opportunity Commission to
Lesechka [4]

Answer: Mean = 3.5 , median = 2.5, mode = 2, geometric mean = 2.74

Median is the most appropriate measure of central tendency.

The least appropriate = mean

Yes there is an outlier.

Step-by-step explanation:

Given responses : 5, 4, 2, 1, 1, 2, 10, 2, 3, 5.

First arrange them in increasing order, \sqrt[10]{1\times1\times2\times2\times2\times3\times4\times5\times5\times10 }\\\\=\sqrt[10]{24000} \approx2.74

Its sum = 35

Mean of n observations = (Sum of observations) ÷ n

Mean = (35) ÷ 10

=3.5

Here n =10 (even)

Median = average of middle most numbers = \dfrac{2+3}{2}=\dfrac52=2.5

Mode = most repeated number = 2    (thrice)

geometric mean = \sqrt[n]{x_1\times x_2\times.... x_n}

10 is an outlier as it is very large as compare to other numbers.

When outlier is present in data , the median is the most appropriate measure of central tendency.

Mean affected badly by the outlier so it the least appropriate.
