The mean of 20,12,29,15,49

1 answer:

8 0

To find the mean of this set of data you must add all the numbers together, then divide by the numbers that you have. Since you have 5 numbers you would divide by 5 after adding them together.

1st: ADD!!
20 + 12 + 29 + 15 + 49 = 125

2nd: divide by 5!
125 ÷ 5 = 25

So the mean of this data set is 25.

Good Luck! :)

Answer: Math, Science, Art, Social Studies, English, Other.

Step-by-step explanation:

First, Here's the table:

Art: 4/25

English: 13%

Math: 0.28

Other: 7%

Science: 21/100

Social Studies: 0.15

Next, lets convert to percents:

A: 4/25 = 16%

E: 13% = 13%

M: 0.25 = 25%

O: 7% = 7%

S: 21/100 = 21%

SS: 0.15 = 15%

Finally, put into order, You have: Math, Science, Art, Social Studies, English, Other.

Step-by-step explanation:

$(3r + 4) + (8r - 2) = 90$

$3r + 4 + 8r - 2= 90$

$11r = 88$

$r = \frac{88}{11} \\$

$r = 8$

<h2>Steps:</h2>

So firstly, this function is asking us to divide f(x) by g(x) so let's set that up as such:

$(\frac{f}{g})(x)=\frac{x^2-x-6}{1}\div \frac{x-3}{x+2}$

Next, remember that <u>dividing by a number is the same as multiplying by its reciprocal.</u> To find the reciprocal of a number, flip the numerator and denominator around. With this info, flip the second fraction to it's reciprocal and change the sign to multiplication:

$(\frac{f}{g})(x)=\frac{x^2-x-6}{1}\times \frac{x+2}{x-3}$

Next, we are going to factor x² - x - 6. Firstly, what two terms have a product of -6x² and a sum of -x? That would be -3x and 2x. Replace -x with 2x - 3x:

$(\frac{f}{g})(x)=\frac{x^2+2x-3x-6}{1}\times \frac{x+2}{x-3}$
