Sample Answer: First, find the mean of the data set by averaging. Next, find the absolute deviations for each data point. That is, find the distance each point is from the mean. Then find the mean of the absolute deviations.

Talib is trying to find the inverse of the function to the right. His work appears beneath it. Is his work correct? Explain your

Rasek [7]

To find the inverse of a function, we make the independent variable the subject of the formula.

Thus, the inverse of the given function is evaluated as follows.
$f(x)=-8x+4 \\ y=-8x+4 \\ -8x=y-4 \\ x= \frac{y-4}{-8} \\ f^{-1}(x)=\frac{x-4}{-8}$

From the work show, it can be seen that Talib's work is correct.

Determine which answer choice matches the dot plot you drew?

Vesnalui [34]

Answer:

Step-by-step explanation:

Given data are :

{1,2,2,2,2,4,4,5,6,6,8,8,8,10}

1 appears only once so there will be 1 point above number 1 in the dot plot.

Then choice B or C or D are possible choices.

2 appears 4 times so there will be 4 points above number 4 in the dot plot.

Then choice B or C or D are possible choices.

4 appears 2 times so there will be 2 points above number 2 in the dot plot.

Then choice C or D are possible choices.

5 appears once once so there will be 1 point above number 5 in the dot plot.

Only choice that satisfies those results is C.

Hence correct answer is C.

dolphi86 [110]

Answer:

11 nickels, 15 dimes, 22 quarters

Step-by-step explanation:

number of nickels = x

number of dimes = x+4

number of quarters = 2x

- - - - - -

total of nickels = 5x cents

total of dimes = 10x + 40 cents

total of quarters = 50x cents

- - - - - -

755 = 5x + 10x + 40 + 50x

755 = 65x + 40

715 = 65x

x = 11

x+4 = 15

2x = 22
