What is the mean absolute deviation of the data set?

Ronch [10]

Answer:

the mean absolute deviation of the data set is 2.

Step-by-step explanation:

To calculate the mean absolute deviation of a data set, we need to follow the following steps:

Step 1: Calculate the mean.

Step 2: Calculate how far away each data point is from the mean (always keeping a possitive distance).

Step 3: Calculate the mean of the deviations.

Step 1: The mean of the data set is:

Mean = (12 + 10 + 10 + 8 + 6+ 7 + 7 + 12)/8 = 72/8 = 9

Step 2:

{12 -9, 10-9, 10-9, 9-8, 9-6, 9-7, 9-7, 12-9} = {3, 1, 1, 1, 3, 2, 2, 3}

Step 3: (3 + 1 + 1 + 1 + 3 + 2 + 2 + 3)/8 = 2

In conclusion, the mean absolute deviation of the data set is 2. Which corresponds to the option B.

A baker is making walnut bread. The recipe uses 2/3 cups of walnuts for each bread recipe. The baker has 7 1/2 cups of walnuts.

Lady_Fox [76]

Answer:

11 breads

Step-by-step explanation:

Note that:

1 bread recipe = 1 bread

From the above question, we know that:

2/3 cups of walnut = 1 bread

7 1/2 cups of walnut = x breads

Cross Multiply

2/3 cups × x breads = 7 1/2 cups × 1 bread

x breads = 7 1/2 cups × 1 bread/2/3 cups

x breads = 7 1/2 ÷ 2/3

x breads = 15/2 ÷ 2/3

x breads = 15/2 × 3/2

x breads = 45/4

x breads = 11 1/4 breads

Maximum full recipe = 11 breads.

Therefore, the MAXIMUM numbers of full recipe of walnut bread the baker can make is 11 breads.

Whats x solve 1/3x-2/3=-18

Kazeer [188]

Answer:

$x=-52$

Step-by-step explanation:

multiple everything by 3 to get rid of the fractions

$3(1/3x-2/3=-18)\\1x-2=-54\\$

rewrite

$x-2=-54$

add 2 to both sides

$x-2+2=-54+2\\x=-52$
