40 points | Sierra and Alek each have five cousins. Their ages are listed below.
faust18 [17]

Find the mean for both:

Sierra: 2 + 11 + 12 + 13 + 15 =  53

53/5 =10.6

Median is the middle value = 12

Alek: 9 + 11 + 11 + 12 + 13 = 56

56/5 = 11.2

Median = 11

A: The medians do not equal the mean.

B: Sierra's are more spread out, ( no identical ages and a greater range ).

C: Sierra's mean is less than Alek.

D. Sierra has an outlier (2).

9 over 3x = 4 over x + 2
Elan Coil [88]

The equation that we have been given is:

\frac{9}{3x}  =  \frac{4}{x+2}

In order to solve for the value of 'x', we'll have to use cross-multiplication.

Cross-multiplication is a method in which the numerator of one fraction is multiplied by the denominator of another fraction that it is equal to.

Let's cross-mutliply the numerators and denominators:

\frac{9}{3x}  =  \frac{4}{x+2}

9*(x+2) = 4*(3x)

Distribute the numbers into the parentheses.

9x + 18 = 12x

Simplify by subtracting both sides by 9x:

9x - 9x + 18 = 12x - 9x

0 + 18 = 3x

18 = 3x

3x = 18

Divide both sides by 3:

\frac{3x}{3} = \frac{18}{3}

<u>x = 6</u>

<u></u>

Let me know if you'd like me to explain anything I did here.
