The answer will be 0.40 because 2 divided by 5 is 0.40
What you have to do to be able to find the answer is $672 divided be $12. That should give you how many cars the soccer team washed.
Answer:
We want to verify if the true proportion of the alumni provide monetary contributions is higher than 0.15 (Alternative hypothesis), the system of hypothesis are.:
Null hypothesis:
Alternative hypothesis:
And the best answer for this case would be:
Ha: p > 0.15
Step-by-step explanation:
Information given
n=250 represent the random sample taken
X=40 represent the number of people on the alumni mailing list
estimated proportion of people on the alumni mailing list
is the value to verify
z would represent the statistic
represent the p value

Answer:
It means that it has no slope, and it is sort of a vertical asymptote, because the Y value increases but the X value stays the same, there is no change in the graph.
Step-by-step explanation:
X=3 if we use the points (3,1) and (3,2), and use the slope equation we get:
m=y2-y1/x2-x1
m=2-1/3-3
m=1/0
no slope
