Let's start with the mean.

To find the mean of a data set, add all the numbers, then divide by the number of numbers there are.

10 + 1 + 10 + 15 + 1 + 7 + 10 + 1 + 6 + 13 = 74
74/10 = 7.4

The mean is 7.4

Now for the median.

To find the median put all the numbers in order, then find the middle number.

1, 1, 1, 6, 7, 10, 10, 10, 13, 15

The number in between 7 and 10 is 8.5
The median is 8.5

And finally, the mode.

To find the mode, find the number that appears the most.

1, 1, 1, 6, 7, 10, 10, 10, 13, 15

In this case, there are two modes. 1, and 10.

Hopefully this helps! If you have any more questions or don't understand, feel free to DM me, and I'll get back to you ASAP! :)

Mean: 7.6

Median: 10

Mode: 10

Explanation: I am sure you missed an extra 10 in your problem. There are supposed to be four 10's (Well at least in my problem). The rest you know, the answer are stated for the set of data: 10, 1, 10, 15, 1, 7, 10, 10, 1, 6, 13.

A right triangle's height is 3 times the length of its base. if the area of the triangle is 600, what is the height?

Anon25 [30]

<span>a = 1/2 x b x h

h = 3b

so 1/2 x b x 3b = (1/2)(3b^2) = 150

(150 x 2)/3 = b^2

100 = b^2

b = square root of 100 = 10

h = 3b = 3 x 10 = 30</span>

Ajax is 5 and 1 fourth feet tall. His sister is 3 eighths foot shorter than Ajax How tall is Ajax Sister?

user100 [1]

Answer:

$4\frac{3}{4}$ feet tall

Step-by-step explanation:

Ajax is "5 and 1 fourth feet tall", which can be written as the mixed number $5\frac{1}{4}$ .

His sister is "3 eighths foot shorter", so she's 3/8 feet shorter than 5 1/4.

So, this is just a subtraction problem:

$5\frac{1}{4} -\frac{3}{8}$

To solve this, we want to convert 5 1/4 into an improper fraction, which is: $\frac{21}{4}$ . Now, we want to find a common denominator. In this case, that common denominator is 8, so $\frac{21}{4} =\frac{42}{8}$ .

Finally, we subtract 3/8 from 42/8: $\frac{42}{8} -\frac{3}{8} =\frac{39}{8}$ . So, Ajax's sister is 39/8 feet. Converting this into a mixed number, we have: 39/8 = 4 $\frac{6}{8} =4\frac{3}{4}$ .
