Answer:
B is correct
Step-by-step explanation: an infinite number of solutions means a coincident line...it is the same line
3y = 2x - 9...divide by 3
y = 2/3x - 3...hmm...same line as answer choice b....they are coincident lines and have infinite solutions
Answer:
55 YRS
Step-by-step explanation:
T=INTEREST X 100%/PRINCIPAL X RATE
T=4400X100%=440000%/4000 X 2%
T=440000%/8000%
T=55 YRS
Answer:
1 is a increase
2 is decrease
Step-by-step explanation:
Answer:
The expression is 
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the z-score that has a p-value of
.
The margin of error is of:

90% confidence level
So
, z is the value of Z that has a p-value of
, so
.
What expression would give the smallest sample size that will result in a margin of error of no more than 3 percentage points?
We have to find n for which M = 0.03.
We have no prior estimate for the proportion, so we use
. So






The expression is 
Answer:
y = 2x − 6
