Answer:

mean = 2

MAD = 3/4

Step-by-step explanation:

1, 3, 2, 2, 1, 3, 3, 1

To find the mean, add up all the numbers and then divide by the number of terms

(1+ 3+ 2+ 2+ 1+ 3+ 3+ 1)/8 = 16/8 = 2

To find the mean absolute deviation

subtract the mean and the number and then take the absolute value, add them together and then divide by the number of terms

|(1-2)| +|(3-2)| +| 2-2| +|2-2|+|1-2| +|3-2|+|3-2| +|1-2|

Jason went to a carnival where he could goon all rides for a flat fee of $30 but he had to pay $2 for each arcade game he played
enot [183]

Answer:

He played 7 arcade games.

Step-by-step explanation:

The amount paid in relation to the number of games played can be modeled by a linear function in the following format:

A(n) = F + gn

In which F is the flat rate and g is the price of each game.

Flat fee of $30 but he had to pay $2 for each arcade game he played.

This means that F = 30, g = 2

So

A(n) = 30 + 2n

Jason spent $44. How many arcade games did he play?

This is n for which A(n) = 44. So

A(n) = 30 + 2n

44 = 30 + 2n

2n = 14

n = \frac{14}{2}

n = 7

He played 7 arcade games.

What is 45/18 as a mixed number?
mr_godi [17]
45 / 18 as a mixed fraction...
To change the improper fraction to the mixed fraction you have to:-
first divide (as you divide) so that you can get remainder, quotient, divisor and dividend.
i.e 45 is dividend and 18 is divisor.

45 / 18 = 2  9 / 18 where 2 is quotient and 9 is remainder...

so the ans is 2  9 / 18

Write an equation of a line that has a slope of -2 and passes through the point (1,4)
RoseWind [281]

Answer:

y = -2x + 6

Step-by-step explanation:

Since we already have the slope we just need to find the y-intercept.

To do that just plug in the point you were given. (1,4)

4 = -2(1) + b (b represents the y-intercept)

4 = -2 + b (add 2 on both sides)

6 = b

y = -2x + 6 is the equation

Hope this helps!!
