Answer:

In statistics , the population is the set of all possible observations as per the researcher's objective .

For example if a researcher wants to find the average height of teenager of age group between 13 year and 15 years in Seattle, he will need the data of the population of height of teenager of age group between 13 year and 15 years in Seattle.

Here , A teacher needs to find out how many seventh graders will be going on a field trip.

Clearly as per her objective she need the data of all seventh graders .

So , the best describes the population that the teacher should survey would be : All seventh graders.

Step-by-step explanation:

3. The tree increased in height each month until the time period between month 9 and month 11.  

Step-by-step explanation:            

We have been given a table that shows the height of the tree that Margo planted over an 11-month period.

Let us see which of the given statement can be supported by the information in the table.

1. The tree increased in height each month during the entire 11-month period.

We can see from our table of data that Margo's tree increased till 9 months and its height decreased between 9 to 11 months from 3 feet to 1.8 feet, therefore, first statement is not true.

2. The tree decreased in height each month during the entire 11-month period.

We can see from our table that height of Margo's tree increased till 9 months from 1.4 feet to 3 feet and its height decreased between 9 to 11 months from 3 feet to 1.8 feet, therefore, second statement is not true.

3. The tree increased in height each month until the time period between month 9 and month 11.

We can see that height of tree increased for 9 months (1.4 ft to 3 ft) and between 9 to 11 months height decreased (3 ft to 1.8 ft), therefore, our 3rd statement is true and the information given in the table is supporting this statement.

4. The tree decreased in height each month until the time period between month 9 and month 11.

We have seen that the tree increased in height each month until the time period between month 9 and month 11, therefore, our 4th statement is not true.

i hope this helps

A cyclist rides his bike at a rate of 5 kilometers per hour.what is this rate in
il63 [147K]

Answer:

rate is 8 miles per hour and he travels 40 miles per 5 hours

Step-by-step explanation:

The story problem told that i should assume that 1 mile is 1.6 km

so 5km/hr is equal to 8m/h

i got it by multiplying 5 by 1.6 so i can change from the unit km to mile

so about the miles per 5 hours just multiply the 8 mph by 5 so it is 40

40miles per 5hrs

hope i made it clear
