Answer:
Cluster sampling!
Step-by-step explanation:
(1, 22), (3, 18), (5,14), (6, 13), (8,5)
(1, 23), (3, 18), (5,14), (6, 11), (8,7)
you plot there on a graph. do you know how to place on a graph?
if not, the line going up and down is the x-axis and the line going side to side is the y-axis,
for example (4,7) it would be (x,y)
i really hope this helps :)
16
3/4y-7=5
*multiply both sides of the equation by 4
= 3y-28=20
*move <u>constant</u> to the right-hand side and change its sign
=3y=20+28
*add the numbers <u> </u>
=3y=48
*divide both numbers by 3
and that's how you get 16
16 weeks
Assuming that each month is around 4 weeks, multiply that number by 4 months and you will get 16 weeks in total.
Remark
This is an "in theory" type of question. She's going to actually need a little more.
Area 1
L = 15
W = 12 1/3
Area = L*W
Area = 15 * 12 1/3 I wonder if you know what the distributive property is. I'll try it. If you don't understand, leave a remark
Area = 15 * (12 + 1/3) Multiply both parts by 15
Area = 15*12 + 1/3 * 15
Area = 180 + 5
Area = 185 square inches.
Area 2.
This is a little harder because their are
2 fractions.
The easy way to do this is change to decimals
L = 10 1/3 = 10.33333333
W = 10 1/4 = 10.25
Area = 10.3333333 * 10.25
Area = <u> 105.92</u> Add
Total Area
The total area = 290.92
