A. 1)5.5 2)4.5 3)5.75 4)6.25 B. 1.75 C. A correct B incorrect C incorrect D correct
Step-by-step explanation:
Mean is a fancy way of saying <em><u>Average </u></em>, when calculating average you add all the numbers and divide by how many numbers there are:
<em><u>A</u></em>
<u>1.</u>
8+6+3+5=22/4=5.5
<u>2.</u>
5+7+4+2=18/4=4.5
<u>3.</u>
8+7+5+3=23/4=5.75
<u>4.</u>
6+8+4+5=25/4=6.25
<em><u>B</u></em>
largest mean is 6.25, smallest mean is 4.5:
<u>Subtract lowest mean from highest mean:</u>
6.25-4.5=1.75
<em><u>C</u></em>
<u>A)</u>
this is correct because averaging your average gives an overall average,
<u>B)</u>
if a is correct b has to be incorrect
<u>C)</u>
if D is correct C must be incorrect
<u>D)</u>
The closer they are together, that means more likely to be accurate because they are almost the same

Answer:
D = 
Step-by-step explanation:
The students in this question are trying to pay back only half of the current debt (d) with the fundraiser (D). Since debt is money that is owed it would therefore be represented as a negative but in this case the fundraiser needs to be positive since it is money gained. So since we have a negative we would need to divide by -2 in order for the total to be positive.
D =
Finally, we are left with this equation which shows the debt that will be repaid through the fundraiser
