Answer:
$1,280 every year and $106.66 every month.
Step-by-step explanation:
You would do 4,000 by 4. Which would be 1,000. Then you would divide 560 by 4. After, you add both of your products together and you get 1,280. Obviously there are 12 months in a year, so you would divide your sum by 12. Then you would get 106.66. Basically, that is how you would get the answer.
I hope this helps!

Answer:
x = 4
Step-by-step explanation:
After you simplify the left side by eliminating parentheses and collecting terms, you have a 2-step linear equation.
-3(4x +3) +4(6x +1) = 43 . . . . . . given
-12x -9 +24x +4 = 43 . . . . . eliminate parentheses
12x-5 = 43 . . . . . . . . . . . collect terms (now a 2-step equation)
12x = 48 . . . . . . . . . . step 1, add the opposite of the unwanted constant
x = 4 . . . . . . . . . . . step 2, divide by the coefficient of x
The solution is x = 4.

<em>Check</em>
-3(4·4 +3) +4(6·4 +1) = 43 . . . . substitute for x
-3(16 +3) +4(24 +1) = 43
-3(19) +4(25) = 43
-57 +100 = 43 . . . . . true
Answer:
25%
Step-by-step explanation:
Percent change = 100 - 80
|80|
x 100 = 20
80
x 100 = 25

Answer:
The minimum sample size necessary is 2305.
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 zscore that has a pvalue of 
.
The margin of error is:
For this problem, we have that:
95% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The researcher wishes to be accurate within 2% of the true proportion. Find the minimum sample size necessary?
We need a sample size of n.
n is found when M = 0.02. So
Rounding up
The minimum sample size necessary is 2305.
