The mean is the average. You find it by adding all of the numbers in your set together, and then dividing that sum by the number of numbers that you have. For example, this is my set:

12 32 11 8 24

I would add those number together

12 + 32 + 11 + 8 + 24 = 87

Then I would divide 87 by the number of numbers I have, which, in the examples case is 5.

87 / 5 = 17.4

-1.3n =7.8 need help

xxMikexx [17]

Hey there!

-1.3n = 7.8

First, you have to DIVIDE both sides by -1.3

-1.3n / -1.3 = 7.8 / -1.3

Cancel out: -1.3 / -1.3 because it gives you the value of 1

Keep: 7.8 / -1.3 because it gives us the value of n

7.8 ÷ -1.3 = -6

Thus, n = -6 ✅

Good luck on your assignment and enjoy your day!

Find f(-2) for (x) = 3 . 2^x<br> O A. -36<br> O B. -12<br> O c.1/36<br><br> O D. 3/4

nydimaria [60]

$\sf f(x) = 3 \ * \ 2^x$

insert x = -2

$\sf f(-2) = 3 \ * \ 2^{-2}$

$\sf f(-2) = 3 \ * \ \dfrac{1}{4}$

$\sf f(-2) = \dfrac{3}{4}$

option D. 3/4 will be the correct answer.

Answer:

x:(x +15)

Step-by-step explanation:

The corresponding sides that are in proportion are apparently ...

PS:PQ = PT:PR

PT = x

PR = x+15

so the proportion of interest is ...

28:40 = x:(x+15)
