you can make it into a fraction just putting it like this 9/12

well 12 - 9 = 3

so we divide by it

In a mathematics class, half of the students scored 79 on an achievement test. With the exception of a few students

Yakvenalex [24]

In this situation, you have:
The mode is 79 (that’s the most common number).
The median is 78.5 (the middle value or the average of the two middle values, since there is an even number of test scores).
The mean is less than both of those, as it was brought down by the few scores of 49.

The means the mean will be less than median.

Assume that you have a binomial experiment with p=0.4 and a sample size of 100. the expected value for this binomial distributio

UkoKoshka [18]

In Binomial distribution, the expected value or mean is given by,
E(X) = np
where, p = probability of success and n=number of sample size.

E(X) = 100×0.4 = 40

What are the values the values of a and b?

Setler [38]

The segment marked 20 is the geometric mean of the two pieces into which it splits the hypotenuse. You get the proportion

$\frac{20}{a} = \frac{21}{20}$

Solving,

$21a =(20)(20) \\ 21a = 400 \\ a = \frac{400}{21}$

To find b, use the fact that b is the geometric mean of the whole hypotenuse, 21 + a, and the part that is attached to it, a.

$\frac{b}{a} = \frac{21+a}{b}$

A little arithmetic shows that $21+a = \frac{841}{21}$ .

$\frac{b}{\frac{400}{21}} = \frac{\frac{841}{21}}{b} \\ b^2 = \frac{336400}{441} \\ b=\frac{580}{21}$
