Mean: add A1+A2+A3+A4+……..+An then divide by 2 means 8+5+7+10+15+21=66/2=33
Answer:
the question you typed is wrong but that on the picture is correct and the correct table which satisfied the equation y =1/4x + 7 is table C
15.
2500 X 15 = 37500
37500 ÷ 100 = 375
375 + 200 = 575
The answer is C.

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.

Number 1 and number 3 are the same because if you are purchasing three tires that is 75% off the tires you need and one of them you get free. the free one becomes the overall discount of 25% off. number 3 is the same, the one quarter represents 25% off of the purchase.
