Answer:
A linear function is represented
Step-by-step explanation:
The table is:
x f(x)
0 10.00
1 10.02
2 10.04
3 10.06
4 10.08
5 10.10
If we compute the difference between two consecutive function values and we divide it by the difference between their associated x values we get:
(10.02 - 10.00)/(1-0) = 0.02
(10.04 - 10.02)/(2-1) = 0.02
(10.06 - 10.04)/(3-2) = 0.02
(10.08 - 10.06)/(4-3) = 0.02
(10.10 - 10.08)/(5-4) = 0.02
This constant result indicates that a linear function is represented.
The answer is $265 (how much did she make altogether)
The equation is x=6h+6
1. 4 times 6
2. 8 divided by 2
3. 4 squared 2
"<span>all real numbers between 3 and 10 inclusive" could not be the answer, because these are x-values (values of the independent variable).
"</span><span>all real numbers between 19 and 54 inclusive" is the range. Why? Because in year 3, f(3) = height of tree = 5(3) + 4 = 19 feet.
In year 10, f(10) = 5(10) + 4 = 54 feet. </span>
Answer:
The 90% confidence interval for the mean time required by all college graduates is between 5.36 years and 5.44 years.
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 Ztable as such z has a pvalue of
.
So it is z with a pvalue of
, so
Now, find the margin of error M as such
In which
is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 5.4 - 0.04 = 5.36 years.
The upper end of the interval is the sample mean added to M. So it is 5.4 + 0.04 = 5.44 years.
The 90% confidence interval for the mean time required by all college graduates is between 5.36 years and 5.44 years.
