This is a very good question to know about. People who make tests really like it.

The way to solve it is to make the slower car stop and use the difference in speed = to the rate. then do it as an ordinary d = r*t problem.

The difference in speeds  is 44 - 36 = 8 miles/ hour.
d = 260 miles
r = 8 mph
t = ???

t = d/r
t = 260/8
t = 32.5 hours.

Thats 32 1/2 hours.

p values for chi-square tests provide a quantitative measure of the probability that the results of another replicate experiment
nlexa [21]

Answer:

0.05

Step-by-step explanation:

P value that is less than 0.05, that is P < 0.05 means that the null hypothesis is false and should be rejected. If the P value is greater than 0.05, that is P > 0.05, it means the null hypothesis is true. The P value is also called the calculated probability value. P value subtracted from 1 is the probability that the alternative hypothesis is true.

8 and 3/10 because the 3 is in the ones place so you make that a fraction which would be 3/10. Then 8 would be a whole number. Hope this helps!
