Traverion wants to find the answer to the question “How much money does the average college professor make?” He surveys 50 professors from the university in his hometown. Which best describes whether or not the results of his survey would represent the responses from the entire population of college professors?
The results do not represent the population because not all college professors actually responded.
The results do not represent the population because the sample does not represent professors from different areas.
The results represent the population because the sample contained college professors and the population is college professors.
The results represent the population because he sampled a large number of professors.

Answers

Answer: I'm pretty sure it's the second option, The results do not represent the population because the sample does not represent professors from different areas.

Step-by-step explanation: It wants the average pay of professors everywhere,not the average of that specific college. I hope this helps sorry if I'm wrong :)

Answer:

B. The results do not represent the population because the sample does not represent professors from different areas.

(03.05 MC)Andrea has $18 to spend. She spent $6.50, including tax, to buy a notebook. She needs to save $5.75, but she wants to buy a snack. If candy bars cost $1.15 per package including tax, what inequality would show the maximum number of packages that Andrea can buy? Solve your inequality by showing your work and steps.

Answers

Answer: She can only buy 1 snack

Step-by-step explanation: All right, but because she had 18 bucks at first, write it down. You'd write down $18 and then spend $6.50 on a notebook for Andrea. Write it down too. But now you're going to make $18 - $6.50. That's equivalent to $11.50. Andrea, however, has to save $5.75. so, deduct it from the $11.50 that you wrote $6.50. Write $18-$6.50=$11.50 Okay, but now that you have written down $11.50, deduct 5.75 (for Andrea's savings) and then $11.50 - $5.75 = $5.75. She's only gonna buy one snack

Which linear function has the greatest y-intercept? y = 6 x + 1 On a coordinate plane, a line goes through points (0, 2) and (5, 0). On a coordinate plane, a line goes through points (1, 2) and (0, negative 3). y = 3 x + 4.

Answers

Answer:

y = 6x + 1 (0,2) (5,0)

Step-by-step explanation:

Really just need to pay attention where the x coordinate is at. If at 0, and the y coordinate is elsewhere, you will be able to tell where the y intercept is. Usually, you quickly draw a graph if the numbers are more complex.

This is the actual answer:

The missing values are PU, PU ≅ PU, UR, PR, and Triangle RUP by applying Corresponding parts of congruent triangles are congruent.

What is congruence in the triangles?

The measurements of the sides and angles of two or more triangles determine their congruence. A triangle's size is determined by its three sides, and its shape is determined by its three angles. If the pairs of corresponding sides and angles of two triangles are equal, they are said to be congruent.

We have:

As we can see in the diagram,

First, we will draw PU

PU is the common side for both the triangles

PU ≅ PU (reflexive property)

UO ≅ UR (given)

PO ≅ PR (given)

By the property of SIde-Side-Side

The triangle OUP ≅ Triangle RUP

By Corresponding parts of congruent triangles are congruent:

Angle O ≅ Angle R (proved)

Thus, the missing values are PU, PU ≅ PU, UR, PR, and Triangle RUP by applying Corresponding parts of congruent triangles are congruent.

Read the excerpt from "Egyptian Tombs: A Grave Matter.From the twenty-fifth century BCE, pharaohs tombs were located inside grand pyramids. The pyramids served as giant grave markers; however, they also served as treasure markers for grave robbers. These wicked people would strip the tombs bare of all valuables. Then they would sell the stolen items for a large amount of money. Stealing from the dead was bad enough, but for the ancient Egyptians, the act also threatened the pharaohs afterlife.Based on the details in the excerpt, what conclusion can be drawn about the pharaohs of ancient Egypt?They went to great lengths to ensure that their tombs were prepared for the afterlife by placing valuables inside. They liked the pyramid shape, so they used it as a tomb.They thought that giant grave markers would protect them against grave robbers.They placed more emphasis on their current lives than on their afterlives.
