Thus is a linear equation, so you want to isolate m so you can compare the variable m to a constant.
You begin by getting rid of -9 by adding 9 (its opposite) since a negative plus a positive can me zero. Then you add 9 to (-13) which is the same as 13-9 but with a negative value, so you get -4.
The answer is -4
A sample is a small subset of a population, on which startistical analysis is carried out to obtain the characteristics of the population.
Sampling is the process of selecting units (e.g., people, organizations) from a
population of interest to obtain the characteristics of the population.
When drawing a sample, it is important that all the components of the population of interest is adequately represented.
Thefollowing samples are categorised based on whether they fairly represent the population of interest or not.
1.) M<span>easuring the heights of every fiftieth person on the school roster to determine the average heights of the boys in the school.
Here, the population of interest is the boys in the school. Drawing a sample of every fiftieth person on the school roster will contain both boys and girls whereas girls are not needed for the purpose of the survey.
Threfore, the sample does not represent fairly the population of interest.
2.) C</span><span>alling
every third person on the soccer team’s roster to determine how many of
the team members have completed their fundraising assignment.
Here, the population of interest is the team members, so drawing a sample of every third person on the soccer team's roster represents fairly the population of interest.
3.) </span>O<span>bserving every person walking down Main Street at 5 p.m. one evening to determine the percentage of people who wear glasses.
Here the population of interest is people who wear glasses, though observing people walking down the road might be a good way to drawing this sample, but the sample will be biased because by 5 pm, the sum will be down and the people who wear glasses because of the sun might not have their glasses on again.
So this sample does not fairly represent the population of interest.
4.) </span>Sending
a confidential e-mail survey to every one-hundredth parent in the
school district to determine the overall satisfaction of the residents
of the town.
Here, the population of interest is the residents of the town and not all residents of the town might be a parent.
So, the sample of one-hundredth parent in the school district does not fairly represent the population of interest.
5.) T<span>aking
a poll in the lunch room (where all students currently have to eat
lunch) to determine the number of students who want to be able to leave
campus during lunch.
Here, the population of interest is the students and taking a poll in the lunch room (where all students currently have to eat lunch) fairly represent the population of interest.
Therefore, the samples that fairly represent the population are:
</span>
<span>C<span>alling
every third person on the soccer team’s roster to determine how many of
the team members have completed their fundraising assignment.
and
</span></span>T<span>aking
a poll in the lunch room (where all students currently have to eat
lunch) to determine the number of students who want to be able to leave
campus during lunch.</span>
The answer would be just 2 because it didn't turn to a fraction.<span />
Could you provide image of both houses? Brainly crops ur pics to be a square so it only shows half of the brick house :).
Answer:
C and E
Step-by-step explanation:
The variable "y" has to be by itself so here is the breakdown to that:
-3x + 6y + 5 = - 7
6y + 6 = 3x - 7
6y = 3x - 7 - 6
6y = 3x - 12
6y/6 = 3x/6 - 12/6
y = 1/2 x - 2
Then you would graph -2 --> (0, -2) and use 1/2 to navigate upwards to get your answers.
