Carl and Tamera want to compare their tests in math class. They have taken six tests. Should they use the mean, median or mode t
Roman55 [17]

Answer:

Mean

Step-by-step explanation:

I said mean because it would allow both Carl and Tamera to average their scores and compare one side by side rather than comparing 6 each which would just be time consuming and it seems like it wouldn't be any other choices.

14/2 three equivalent ratios
Anna71 [15]

Answer:

Three equivalent ratios of  \frac{14}{2} are \frac{7}{1}, \frac{21}{3} and \frac{28}{8}.

Step-by-step explanation:

We are given a fraction \frac{14}{2}.

We need to find the three equivalent ratios/fractions of \frac{14}{2}.

The common factor of 14 and 2 is 2.

So, dividing top and bottom by 2, we get

14÷2 = 7 and 2÷2 that is \frac{7}{1}.

Multiplying \frac{7}{1} fraction by a common number 3 in top and bottom, we get

7 × 3 = 21

1 × 3 = 6

So, we get another equivalent fraction \frac{21}{6}.

Multiplying \frac{7}{1} fraction by a common number 3 in top and bottom, we get

7 × 4 = 28

1 × 4 = 4

So, we get another equivalent fraction \frac{28}{4}.

Therefore, three equivalent ratios of  \frac{14}{2} are \frac{7}{1}, \frac{21}{3} and \frac{28}{4}.

Simplify 3(2m^3n^-2)^4
Effectus [21]

Answer:

(48 m^12)/n^8

Step-by-step explanation:

Simplify the following:

3 ((2 m^3)/(n^2))^4

Multiply each exponent in (2 m^3)/(n^2) by 4:

3×2^4 m^(4×3) n^(-2×4)

4 (-2) = -8:

3×2^4 m^(4×3) n^(-8)

4×3 = 12:

(3×2^4 m^12)/(n^8)

2^4 = (2^2)^2:

(3 (2^2)^2 m^12)/(n^8)

2^2 = 4:

(3×4^2 m^12)/(n^8)

4^2 = 16:

(3×16 m^12)/(n^8)

3×16 = 48:

Answer: (48 m^12)/n^8
