C) 500
Explanation:
The middle of the box and whisker plot is the line in the middle of the box. That line is over the number 500 on the number line meaning the C would be the correct answer.
22 X = Y
x = number of rooms cleaned
Y = cost
200/22 = 9.09 > 9 rooms
160/22 = 7.25 > 7 rooms
Answer:
see below
Step-by-step explanation:
The rate of change is
f(x2) - f(x1)
------------------
x2-x1
Since this is a line we can pick any two points on the line, one befre x=1 and one after x=1
Let x=0 and x=2
f(2) - f(0)
-------------
2-0
4-2
-------
2
2/2
1
The rate of change is 1
Answer:
10 Hexagonal pieces, 20 Rectangular pieces and 50 Triangular pieces.
Step-by-step explanation:
First let's check how many pieces Missy uses to make one bug design:
1 hexagonal + 2 rectangular + 5 triangular = 8 total pieces.
Is the uses 80 pieces in total, she made a total of 80/8 = 10 bug designs
So now we can calculate how many pieces of each shape she uses just multiplying the amount of bug designs (10) by the number of pieces of each shape:
Hexagonal pieces: 1 * 10 = 10 pieces
Rectangular pieces: 2 * 10 = 20 pieces
Triangular pieces: 5 * 10 = 50 pieces
Answer:
t = $4400 +/- $450
mean = $4400
standard deviation = $450
Step-by-step explanation:
Given;
Base salary b = $2000
Sales s = $8000 +/- $1500
Commission c = 30% sales = 0.3 × s
Total Salary t = base salary + commission = b + c
Commission c = 0.3×s = 0.3×($8000 +/-$1500)
c = $2400 +/- $450
Total salary t = b + c
Substituting the values;
t = $2000 + ($2400 +/- $450)
t = $4400 +/- $450
mean = $4400
standard deviation = $450
