  • #3. 8

Step-by-step explanation:

<u>Frequency of data </u>

  • 6

<u>Sum of data:</u>

<u>Sum of data as per mean and frequencies:</u>

  • 9*6 = 54

<u>Compare the sums:</u>

  • 46 + q = 54
  • q = 54 - 46
  • q = 8

Correct choice is #3. 8

15. Edgar Anderson earns $200 a week plus a 15% commission on all sales over $1,000. If Mr. Anderson's sales for one week are $2
Gwar [14]
15. 

2500 X 15 = 37500
37500 ÷ 100 = 375
375 + 200 = 575
The answer is C.


16. 
The easiest way to answer this question is by going through each answer one by one: 

14:6 = 28:18
28 <span>÷ 14 = 2
</span>18 <span>÷ 6 = 3
</span>Since both numbers were multiplied by different numbers, we can establish that this is not a true proportion. 

42:7 = 6:2 
42 ÷ 7 = 6
7 ÷ 7 = 1
42:7 = 6:1
By dividing both numbers by the same number, we can establish that the answer is wrong. 

2:3 = 3:2
This is obviously wrong. That is because, in ratios, the order counts. So the first 3 is more than the first 2, therefore the second number on the other side of the ratio should be more than the first. 

3:5 = 12:20
12 <span>÷ 3 = 4
</span>20 <span>÷ 5 = 4
</span>Since both numbers were multiplied by the same number, this is a true proportion. 

The answer is D.

Give an example of an absolute value inequality whose answers falls between two values. Give an example of an absolute value ine
mel-nik [20]

Answer:

A) Suppose we have an onedimensional situation.

in the 0 of our x-axis, we have a fruit tree, and we want to rest at a distance no bigger than 6 ft of the tree, then all the possible positions of our resting place are:

x ∈(-6ft, 6ft)

we can write this as: IxI < 6ft

b) now we think the opposite situation, we want to rest at least 6ft away from the tree, then we have that:

x ∉  [-6ft, 6ft].

or IxI > 6ft.

So you can see that the difference in those two cases is if we want to be "inside a given range" (for the first case) or "outside a given range" (for the second case).
