Her scores would be 98, 82, and 81. Their sum would be 261 then you would divide it be 3 and it would give you 87 then to find the median line the numbers up from greatest to least and 82 would be in the middle. To find the range subtract 81 from 98 and it gives you 17. Did this help?

The table shows the number of candid pictures of students for the yearbook for two consecutive years. Year Number of Photos 2015

Elena-2011 [213]

Answer:

The percentage decrease in the number candid student pictures for the yearbook from 2015 to 2016 is approximately 9.3 percent

Step-by-step explanation:

The given data can be presented as follows

Year ${}$ Number of Photos

2015 ${}$ 236

2016 ${}$ 214

The percentage decrease in the number of candid pictures is give by the following formula

$Percentage \ Decrease = \dfrac{Original \ Value- New \ Value}{Original \ Value} \times 100$

Where;

Original value for the number of pictures = 236

New value for the number of pictures = 214

Substituting the values into the equation for the percentage decrease gives;

$Percentage \ Decrease = \dfrac{236- 214}{236} \times 100 = \dfrac{550}{59} \ percent\approx 9.3 \%$

The percentage decrease is approximately 9.3 percent.
