Answer:
15(3p+4r)
Step-by-step explanation:
45p + 60r
factor out 15
15(3p+4r)
Answer:
I think it should be D because the arrow points down and the space between the two points is 7 units

Answer:
5.1
Step-by-step explanation:
Given that:
sample size n = 4
the mean of the original population μ is = 35
and the mean for the sample after treatment M is = 40.1
standard deviation of the sample SS = 48
The difference between the mean for the treated sample and the mean for the original population is therefore calculated as: M - μ
= 40.1 - 35
= 5.1
The standard error of M is = 
The standard error of M is = 
The standard error of M is = 
The standard error of M is = 
The standard error of M is = 24
Answer:
21
Step-by-step explanation:
You can do it two different ways.
1st. Find the scale factor by dividing - 75/25=3 or 72/24=3
This means the scale factor is three
Then multiply the remaining side (7) by the scale factor (3) to get: 21
2nd. Use the Pythagorean Theorem - 75²-72²=x²
441 = x²
√441=x
x=21
First you'd work around the parenthesis, getting you a reduced problem of -2x-6-5.
combine like terms to receive -2x-11
now treat the f(x) as Y and you'll get y=-2x-11; toss it onto a graph and plot the individual points (your answer options)
all points except for A do not touch the line, resulting in your answer to be letter A!
