19.) Mr. Green teaches band, choir, and math. This year, he has 57 students that take at least one of his classes. He teaches band to 25 students. There are 9 students who have Mr. Green for math and nothing else. Use the Venn diagram below: How many students take exactly 2 classes with Mr. Green?

Answer: 26 students take exactly 2 classes check the work below.
25 - ( 7 + 3 + 11) Use order of operations or pemdas
25 - ( 21 ) = 4 ** students who take both Band and Choir

Add 11 + 7 + 3 + 4 + 17 + 9 = 51

Subtract 57 - 42 = 15***Students take Math and Choir

Add 15 + 4 + 7 , these are the sections in the Venn Diagram where two circles share the same space.

15 + 4 + 7 = 26 ***** ANSWER

26 students take exactly two classes.

Mean = ∑x/n

Mode = most frequently occurring score

Median = arrange score in ascending/descending order. Middle score is median (50% percentile). If there are two different middle scores, find their mean.

1. disagree

2. agree

**ANSWER: A mean = –28.5, median = –29.1, mode = –49, range = 40

First put them in order
- 49, - 49 , - 43 , -39 , -18, -14, -12, -9
Add the two middle numbers -39 and -18, it equals -57
Divide - 57 and 2, it equals - 28.5 <--- MEAN

Second add all the numbers together, it equals - 233, then divide by 8, which equals
- 29.1 <---MEDIAN

MODE is the number that happens most, which is -49 <--- MODE

The range is -49 - ( -9 ) = - 40 <-----RANGE

"Just me" you need to make sure you are in connections academy from CALIFORIA they mix up the tests by state............ duh. if you are going to cheat , know your facts. also how about studying or reaching out to your teacher. You deserve your 4/17 haha

Agreed WashingtonJ
