8x + 5(-4x) = 24
8x - 20x = 24
-12x = 24
x = -2
y = -4(-2)
y = 8
Therefore, the point of intersection is (-2,8).
Answer:
It would be option A. 10 Minutes.
Step-by-step explanation:
If you look at the graph, the farthest point, and the time of 10 minutes meet at the point (10, 2,500)
(Really hoping this helps <3)
The next term is double the previous term, so that the
-th term is given recursively by

This rule tells us that



and so on, with the explicit rule

for
.
If 512 is the
-th term in the sequence, then

Answer:
1000miles per hour
Step-by-step explanation:
Answer:
1.165.
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.
In this problem, we have that:
. So


So the correct answer is:
1.165.
