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

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;

The percentage decrease is approximately 9.3 percent.

Step-by-step explanation:
Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.
Answer:
a.) 
b.)

Step-by-step explanation:
a.) We are given the heights and their frequency. We can make a new set:
198, 199, 199, 199, 200, 200, 201, 201, 201, 201, 201, 202, 202
Now find the mean. The mean is found by adding all the numbers in the set, then dividing the total by the number of terms in the set. Add:

Now count the terms. There are 13 terms. Divide the total by the number of terms:

The mean is 200.3.
b.) Use random values like 200, 198 etc. and add them to the total of the last set, then divide by 14 instead of 13 (because there is a new player). Do this until you get a mean of 201 with the new height:

For the new mean to be 201 cm, the new player has a height of 210 cm.

Answer:
The explicit form for the sequence is: 
Step-by-step explanation:
In order to find an explicit form for the given sequence, you have to use the definition of arithmetic sequence and the <em>explicit formula</em>.
An arithmetic sequence is defined as a sequence where the difference of two consecutive terms is a constant.
The <em>explicit formula </em>is:

Where a1 is the first term, d is the common difference and an is the nth term of the sequence.
You have to subtract two consecutive terms to obtain d:
24-13= 11
35-24=11
Therefore d=11
In this case a1=13
Replacing in the formula:

7.8n+10=50
8n+10-10=50-10
8n=40/8
n=5

8.375 = 20g + 75
375 = 20g + 75
– 75 = – 75
300 = 20g
15 = g
