Answer:
2,593,680
Step-by-step explanation:
multiply all the numbers together to get the volume. Is that what you wanted volume?
Slope intercept form is
where
is the slope
and
is the y-intercept
they give us that the slope is 2
so our
then to find
, we temporarily plug in the point they gave us for x and y
so
and solve for
3 = 2 + b
1 = b
so our
put this together and we get
as our answer
Answer:
$44.55
Step-by-step explanation:
10% of 45 is 4.5
45 * 0.1 = 4.5
So subtract 4.5 from 45
45 - 4.5 = 40.5
Now get 10% of 40.5
40.5 * 0.1 = 4.05
Add 4.05 to 40.5
4.05 + 40.5 = 44.55
Answer:
e. We are 90% confident that the average age of all golfers that play on the golf course is between 38.6 and 44.6 years old.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
In this question:
90% confidence interval for the average age of golfers in the course is of (38.6, 44.6). This means that we are 90% sure that the true average age of all golfers in the course is between these two values, that is, the correct answer is given by option e.
