Answer:
D
Explanation:
They make holes in the lithosphere
Solution :
a). Let x denotes ACT scores.
ACT scores = 
Mean, 
Sample variance, 
= 11
b). To test whether or not variance of ACT scores of population (say 
) of the UTC students is significantly more than 8.
Consider the hypothesis :
vs 
It is a right tailed test and α = 0.05
We have
So test statics is
= 8.25
Since our 
and it falls in a acceptation region, hence we fail to reject 
and conclude that variance is not greater than 8 significantly.
Answer: Waves
Explanation:
Coastlines are formed due to the continuous battering of the coast by waves. These waves cause soil erosion when they take some coastline material back to the water as they recede. They also deposit some material on the coast when they make contact.
This causes the coastlines to take different shapes as the process goes on and on. Some coasts will be harder to shape however when the waves will be unable to erode the coast so easily because those coasts are made of harder material like rocks. That's why rocky coastlines stay more of less the same for a long period of time.
A. Measure the soil's volume and then the volume of water that the soil can absorb.
