Answer:
line QR
Step-by-step explanation:
Plane QRB is the front face. Plane TSR is the top face. The planes intersect at the top front edge, line QR.
Answer:
As per the statement:
Adult red wolves vary in length from 137.16 cm to 168.64 cm.
To find the difference in length between the longest and shortest of these wolves.
Longest length of wolves = 168.64 cm
Shortest length of wolves= 137.16 cm
Then;
= 
Substitute the given values we have;
= 168.64 - 137.16 = 31.48 cm
therefore, the difference in length between the longest and shortest of these wolves is 31.48 cm
It will be around 1.6metres

Option 1:
<span>Measuring the heights of every fiftieth person on the school roster to determine the average heights of the boys in the school
</span>
Comment: this might not be a good idea for fairness as we only wish to determine average height of the boys. Taking a group of 50 people randomly, might not give us the same number of boys every time.
Option 2:
<span>Calling every third person on the soccer team’s roster to determine how many of the team members have completed their fundraising assignment
Comment: The context doesn't seem to need a sampling. The number of players in a soccer team is considerably small. We can find exact data by asking in person.
Option 3:
</span><span>
Observing every person walking down Main Street at 5 p.m. one evening to determine the percentage of people who wear glasses
</span>
Comment: To get a more accurate result and fairer sampling, the period of observing could have been longer, for example, observing for 12 hours on that day, or an alternative is to observe at 5 pm for 7 days in a row. It could happen that no one walking down the Main street precisely at 5 pm wears glasses, or it could happen the other way around.
Option 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 taking 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.
Comment: This sampling does fairly represent the population, although it might be an idea to scale down the sample population, i.e. every fiftieth parent.
Answer: Option 4</span>
The midpoint of a line divides the line into equal segments.
The option that proves PQ = LO is (a)
The given parameters are:
P is the midpoint of LM.
So, we have:
Q is the midpoint of NO.
So, we have:
Distance PQ is calculated as follows:
This gives:
Distance LO is calculated as follows:
So, we have:
Thus:
Hence, the correct option is (a)
