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.)
7.50 x 0.30= $2.25
7.50- 2.25= $5.25

The number of rows of beans that are in the garden is 24 rows.
<h3>How many rows of beans are in the garden?</h3>
The first step is to convert feet to inches.
1 feet = 12 inches
30 x 12 = 360 inches
The second step is to divide 360 inches by 15 inches: 360 / 15 = 24 rows

Answer:
Step-by-step explanation:
x*y = 490
x + y = 49
x = 49 - y
y*(49 - y ) = 490
49y - y^2 = 490
0 = y^2 - 49y + 490
This does factor (oddly). It doesn't look like it, but it does.
(y - 35) (y - 14) = 0
y - 35 = 0
y = 35
y - 14 = 0
y = 14
x = 49 - y
Let y = 14
x = 49 - 14
x = 35
x = 49 - y
let y = 35
x = 49 - 35
y = 14
