A cluster sample is one in which the population is divided into groups and a random sample of groups is drawn.
First you move -15 over which makes it 7b=5b+12
then you move 5b over so then its 2b=12
divide b=6
Answer:
1) 20%
2) Choice a.
Step-by-step explanation:
1) is the population initially.
is the population after a year.
represents the population increase factor.
So let's evaluate that fraction:
0.2=20%
2) Let's figure out the population growth in terms of months instead of years.
We want t to represent months.
A full year is 12 months, in a full year we have that
So we want a new P such that since 12 months equals a year.
Let's look at the functions given to see which gives us this:
a)
b)
c)
d)
So a is the function we want.
Also another way to look at this:
where is in years.
where is in months.
And
Answer:
63.9
Step-by-step explanation:
Convert 9% to a decimal: 0.09
710×.09=63.9

Answer:
E) x=0 or y=-5
Step-by-step explanation:
The slope field will have vertical segments when dy/dx is undefined, that is, dy/dx is a division by 0.
We have that
dy/dx=(3y)/(xy+5x)
So the slope field will have vertical segments when
This is when x = 0 or y = -5.
So the correct answer is:
E) x=0 or y=-5
