Each of 8 students reported the number of movies they saw in the past year. This is what they reported: 5, 4, 18, 19, 12, 20, 12
djyliett [7]
Mean is just the average of all of them
So... 5 + 4 + 18 + 19 + 12 + 20 + 12 + 12 = 102
Then you divide that number by the amount of numbers you have so 102 / 8 = 12.75 or rounding it up to 13

For median you have to first put them in order from smallest to largest.
So 4 5 12 12 12 18 19 20
Then you have to find the middle number between them but in this case we have two... 12 and 12. Since they're the same number, the median is 12.

X – 7y = –11<br> 5x + 2y = -18
laiz [17]

Answer:

hope this help you

Step-by-step explanation:

Simplifying

X + -7y = -11

Solving

X + -7y = -11  

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.

Add '7y' to each side of the equation.

X + -7y + 7y = -11 + 7y

Combine like terms: -7y + 7y = 0

X = -11 + 7y

Simplifying

X = -11 + 7y

------------------------------------------------------------------------------------------------------------

Solving

5x + 2y = -18

Solving for variable 'x'.

Add '-2y' to each side of the equation.

5x + 2y + -2y = -18 + -2y

Combine like terms: 2y + -2y = 0

5x = -18 + -2y

Divide each side by '5'.

x = -3.6 + -0.4y

Simplifying

x = -3.6 + -0.4y

Multiply <br> (-3/4) x (-2/9)
xeze [42]

Answer:

\frac{1}{6}

Step-by-step explanation:

When multiplying fractions, you simply multiply numerator by numerator and denominator by denominator, and if possible, you later simplify the answer.

\frac{-3}{4} * \frac{-2}{9} = \frac{6}{36}

\frac{6}{36} / 6 = \frac{1}{6}

Hope it helped,
