Measures of variation: ways to describe measures of central tendency for a data.

the most common measure of variation is range, so in this case, the smallest number is 1, and the largest is 17. This means the range is 16.

Interquartile Range:

Lower q: {1, 2, 4}
Upper q: {8, 12, 17}
Here you have to subtract 12 from 2, which gives you 10.

Mean absolute deviation:
Alright, let's first find the mean...

(1+2+4+5+8+12+17)
---------------------------= 7
7

What is the distance of each number from 7?

1: 6 units
2: 5 units
4: 3 units
5: 2 units
8: 1 unit
12: 5 units
17: 10 units

After adding all of these together, and dividing by 7, you will get...

4.571428 ≈ 4.6 or 5.

I hope these answers help you! Please give me brainliest!

Total rocks = 62

A. Have 4 cases of 2 rocks, and 9 cases of 11 rocks

(4 * 2) + (9 * 11) > 62 ( false)

B. Have 9 cases of 2 rocks, and 4 cases of 11 rocks

(9 * 2) + (4 * 11) = 18 + 44 = 62 rocks (true)

C. Have 9 cases of 2 rocks, and 1 case of 11 rocks

(9 * 2). + (1 * 11) < 62 ( false)

D. Have 1 case of 2 rocks, and 4 cases of 11 rocks.

(1 * 2) + (4 * 11) < 62

If one store is selling 3/4 of a bushel of apples for $9 and another story selling 2/3 of a bushel of apples for $9 which store

NeX [460]

For this case we have,

store 1:

3/4 of a bushel of apples -----------------------> $ 9

1 bushel of apples -------------------------------> x

From here the value of x is cleared, resulting in:

$x =\frac{(1)(9)}{\frac{3}{4} } \\\\x = 12\\$

store 2:

2/3 of a bushel of apples -----------------------> $ 9

1 bushel of apples -------------------------------> x

From here the value of x is cleared, resulting in:

$x = \frac{(1)(9)}{\frac{2}{3} }\\\\x = 13.50 \\$

Therefore it is convenient to buy apples in store 1 because it is cheaper.

Answer:

It is convenient to buy apples in store 1 because it is cheaper. A division must be made for each case because you want to find the unit cost of a product having the total cost and the amount in fraction.
