Answer:

19.5 (Rounded: 20)

Step-by-step explanation:

In math, the mean is every number added together, then divided by the amount of numbers. For example, 1,2,5,4,8 would have a median of 4.

(1 + 2 + 4 + 5 + 8 = 20 ÷ 5 = 4)

Your dot plot has 14 total numbers, meaning that you add up all the numbers and divide by 14.

16 + 17 + 17 + 17 + 17 + 19 + 19 + 19 + 19 + 21 + 22 + 22 + 23 + 25 = 273

273 ÷ 14 = 19.5

If you don't need to round, 19.5 is correct. However, if you need to round my best guess is 20. Good luck!

Answer:

Step-by-step explanation:

Just a tiny mistake.

You forgot the minus symbol in the white boxes, and also, you have to add them, not multiply. So you have

3x + 25 = 5x - 20

Find the value of m. (-3/4)-⁴×(-3/4)-¹¹ = (-3/4)^m

tatiyna

Answer:

m = - 15

Step-by-step explanation:

Using the rule of exponents

$a^{m}$ × $a^{n}$ = $a^{(m+n)}$ , then

$(-\frac{3}{4}) ^{-4}$ × $(-\frac{3}{4}) ^{-11}$ = $(-\frac{3}{4}) ^{m}$ , that is

$(-\frac{3}{4}) ^{(-4-11)}$ = $(-\frac{3}{4}) ^{m}$

$(-\frac{3}{4}) ^{-15}$ = $(-\frac{3}{4}) ^{m}$

Equating exponents gives

m = - 15

Please respond in detail

Serggg [28]

Answer:

No.

Step-by-step explanation:

As x increases 2^x will grow faster than 5 x^2. This is because the x in 2^x is an exponent and its graph grows very steeply compared with 5x^2 , as x increases.

For example when x = 10

5x^2 = 5*10^2 = 500

2^x = 2^10 =1024

When x = 11:

5x^2 = 605

2^x = 2048 and the difference will continue to increase.

I need help please don't know this

SashulF [63]

Answer:

9 is the right answer

Step-by-step explanation:

I. If c = - 4 and d = 10

then $\frac{1}{4}(-4^{3} + 10^{2} )$

= $\frac{1}{4}(-64 + 100)$

= $\frac{1}{4}(36)$

= 9

Hope that help :D
