Determine if the numerical value describes a population parameter or a sample statistic. The average price of a car at the new c

Travka [436]

Answer:

Population parameter

Step-by-step explanation:

Since the average price of a whole town at a new dealership is described. A random sample from a town was not isolated for study. In fact the entire statistics of the town was considered in the mean price of a car. Hence, the average price given in our case will be a population parameter.

A school has two pathways through the math program. At this school, 3/4 of students follow the first path, and the rest take t

VashaNatasha [74]

Answer:

3/5 of students who take the first path and pass

Step-by-step explanation:

* Lets explain how to solve the problem

- There are two pathways through the math program

- At this school 3/4 of students follow the first path

- The rest take the second path

- During one semester, 80% of the students who follow the first path

pass the program

- 20% of the students who follow the second path pass it

- We want to know the fraction of students who take the first path

and pass

* Lets solve the problem

∵ 3/4 of students follow the first path

∵ The rest take the second path

∴ The fraction of the rest = 1 - 3/4 = 1/4

∴ 1/4 of the students follow the second path

∵ 80% of the students who follow the first path pass the program

∵ 80% = 80/100 = 8/10 = 4/5

∵ 4/5 of the students who follow the first path pass the program

∵ 3/4 of students follow the first path

∴ 4/5 of 3/4 of the students of the first path pass

∵ 4/5 of 3/4 = 3/5

∴ 3/5 of students who take the first path and pass

When water cycles through the earth, it only stays in the atmosphere for about 9 days, but it can stay in the ocean for over 3,0

Delicious77 [7]

Answer:

Because the volume of water is higher in oceans than atmosphere

Step-by-step explanation:

Critically looking at water cycle, we could infer that water can exist for a few days in the atmosphere because it also resides on land as well.

The atmosphere is basically a way for the ocean water to run back on land and run off right back into the oceans. It won't come back right away depending squarely on where it goes, but there is a lifetime out of the ocean that balances these times out.

The contributing factor factor to this difference is mainly the volume of water in ocean is higher and evaporation occurs slowly.

Find attached below the picture of water cycle.
