Two angles in a triangle have measures of 23 and 98 what is the third measure of the third angle

Feliz [49]

Answer:

Step-by-step explanation:

As far as I know every triangle has to equal 180°

So if you add 98+23 you would get 121

subtract that from 180 and get 59

Hope this helps!

Explain why the product of 2 times any number is an even number

leonid [27]

If you add 2 odd numbers together eg. 5+5 it would become an even number eg. 10.

If you add 2 even numbers together eg. 60+60 it would stay as an even number eg.120.

The product is basically the same thing as that but instead of adding the same number twice, you multiplying the number with 2 which is the same as adding two of the same numbers.

Six times a number is equal to 10 less than the sum of the number and 3. What is the number?

saul85 [17]

Answer:

n = -7/5

Step-by-step explanation:

Let n = number

6n = (n+3) -10

Combine like terms

6n= n-7

Subtract n from each side

6n-n=n-n-7

5n = -7

Divide by 5 on each side

5n/5 = -7/5

n = -7/5

Can someone show me how to do Mean absolute deviation

morpeh [17]

To find the mean of a set, add up all of the numbers and divide by how many numbers you have. For the first set:
$\mu=\frac{10.7+2.4}2=\frac{13.1}2=6.55$
For the second set:
$\mu=\frac{13.7+2.5}2=\frac{16.2}2=8.1$

To find the mean absolute deviation, (MAD) find the mean of the distances of each number from the mean.
For the first set:
$MAD=\frac{|10.7-6.55|+|2.4-6.55|}2=\frac{4.15+4.15}2=\frac{8.3}2=4.15$
For the second set:
$MAD=\frac{|13.7-8.1|+|2.5-8.1|}2=\frac{5.6+5.6}2=\frac{11.2}2=5.6$
Note that when you only have two data points the mean is directly between them, which is why the distances are the same.

The means-to-MAD ratio is simply that, divide one by the other and that's it.
For the first set:
$6.55\div4.15=1.57831325$
For the second set:
$8.1\div5.6=1.44642857$
