Answer:
- 3.5
- 2
- B
- A
Step-by-step explanation:
Middle School:
Find the median by arranging the data points from smallest to largest.
1, 1, 1, 3, 4, 4, 5, 6 (Take the average of the two points in the middle, 3 and 4)
7/2 = 3.5
High School:
1, 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 4 (Take the average of the two points in the middle, 2 and 2)
4/2 = 2
Most of the points in the middle school plot are four or less.
A (High school students had more variation.)
Answer:
−1.2c+6.3
Step-by-step explanation:
Answer: 7(x+2)(x+3)
Step-by-step explanation:
First, you want to find the GCF, 7 goes into all the terms evenly
so 7x^2 + 35x + 42 = 7(x^2 + 5 + 6)
to factor (x^2+5+6), you want to find two numbers whose product is 6 and whose sum is 5 (2 and 3)
so (x^2 + 5 + 6) becomes (x+2)(x+3)
and 7(x^2 + 5 + 6) becomes 7(x+2)(x+3)
For the answer for number one you will multiply 3/4 and 9 and you will get 6.75 then you roun it to 6 for the answer.
For the answer for for number two postive 8 is to the right of zero so the opposite of 8 would be on the left of zero
