distance/time=2/30
2hours=60*2=120mins
xdistance
2/30=x/120
1/15=x/120
times boht sides by 120
120/15=x
8=x
8 miles
knowlege way
30 mins=1/2 hour
30 mins=1/4 of 2 hours
2=1/4 of 2 hours
2*4=8
8 miles
12+18=30 so together they have $30.00 in all.

10.) 27
Step-by-step explanation:
Answer:
a. We do not have enough evidence to conclude that the two means differ.
b. There is no difference in the population means.
Step-by-step explanation:
a) Results of the test:
Having p - value to be very high, we have strong evidence of not rejecting H o and hence,
We do not have enough evidence to conclude that the two means differ.
b) For a one tailed test,
p - value = 0.115/2 = 0.0575
Interpretation: p - value is the probability of getting the difference as small as obtained in the sample, given that the null hypothesis is true i.e. there is no difference in the population means.
