Answer:
Population is all students from grades 3-12.
Sample is the students who participated in the survey.
Step-by-step explanation:
Given : A survey of third- to twelfth-grade students with a sample size of 2026 found that they devoted an average of 1 hour and 46 minutes per day to using entertainment media.
To find : Identify the population and the sample.
Solution :
The population is defined as it contain all individuals which we want to collect the information.
So, the population consists of all third- to twelfth grade students.
Therefore, Population is all students from grades 3-12.
The sample is defined as a part of population of which information was actually collected.
So, the sample is only the respondents in the survey conducted in 2026.
Therefore, Sample is the students who participated in the survey.
Answer:
a) 79.6
b) 437.8
Step-by-step explanation:
First, you have to do 318.4/4 to find the rate she goes in the duration of an hour. The rate is 79.6, which means she travels at a rate of 79.6 kilometers per hour.
Then, you have to find the distance she takes to travel in 5.5 hours, so you have to do 5.5*79.6 which is 437.8.
So, Hannah travels 437.8 kilometers in 5.5 hours.
Answer:
y=x-4
Step-by-step explanation:
The slope is given by
m = (y2-y1)/(x2-x1)
m = (1--9)/(5--5)
m = (1+9)/(5+5)
= 10/10
= 1
The slope is 1
We have the slope and a point,so we can use point slope form
y-y1 = m(x-x1)
y-1 = 1(x-5)
y-1 = x-5
Add 1 to each side
y-1+1 = x-5+1
y=x-4
This is slope intercept form (y= mx+b)
Answer:
Step-by-step explanation:
We need to find the value of x so that the value of given function becomes 21 .
We have ,
Now , for finding x ,
