Step-by-step explanation:
Growth in population each year = 3%(1500)
= 3/100 × 1500
= 3 × 15
= 45
Therefore, the growth in population in 6 years
= 6 × 3%(1500)
= 6 × 45
= 270
Hence, the population after 6 years = 1500 + 270
= 1770
Answer:
The margin of error is of 0.01.
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Z-table as such z has a p-value of
.
That is z with a pvalue of
, so Z = 1.037.
The margin of error is of:

In which
is the standard deviation of the population and n is the size of the sample.
Standard deviation was 0.21.
This means that 
Sample of 450:
This means that 
What is the margin of error, assuming a 70% confidence level, to the nearest hundredth?



The margin of error is of 0.01.
Step-by-step explanation:
I think both 3 and 9
D options
Answer: 
Step-by-step explanation:
To find the slope of the line , we will write the equation in the form:
where:
slope
y - intercept.
To write
in this form , we will make y the subject of the formula.
Subtract 4x from both sides

Divide through by 2
Therefore :
