Question Category: Using Models for Data
Select the correct answer.

Mr. Walker gave his students a poem to memorize and present to the class. After the presentations, he gathered data about the time each of seven students spent memorizing their poem and the number of errors each made when presenting it to the class.

He used a graphing tool to display the data in a scatter plot, with x representing the minutes spent memorizing the poem and y representing the number of errors. Then he used the tool to find the equation of the line of best fit:

y = -0.118x + 14.327.

Based on the line of best fit, approximately how many minutes did a student spend memorizing the poem if the student made 12 errors when presenting it to the class?

In a collection of​ coins, the number of quarters is​ one-third the number of pennies. The number of quarters is Q. The number of pennies is P. What is the correct formula relating Q to​ P

Answers

Answer:

Q = P/3

Step-by-step explanation:

Let the number of quarters be Q

Let the number of pennies be P

If the number of quarters is​ one-third the number of pennies, this can be expressed as;

Number of quarter = 1/3 of pennies

Q = 1/3 of P

Of means multiplication

The expression becomes;

Q = 1/3 × P

Q = P/3

Hence the formula relating Q to P is

Q = P/3

Answer:

C) x=35

Step-by-step explanation:

First, we know that the total amount of degrees in a rotation is 360. As the picture tells us, the opposite angles will be exactly the same. Taking this information, we can have the following equation:

4x + 2(3x+5) = 360

By now using our linear equation skills, we get:

10x+10=360

10x=350

x=35

The degree amount of x for c) is 35 degrees.

C. Since the angles form a linear pair, their sum equals 180.

So, 2x + 3x + 5 = 180

x=35

D. Since the angles are verticle, they equal each other.

So, 3x + 5 = 5x -57

x=31

Step-by-step explanation:

A public swimming pool that holds 45,000 gallons of water is going to be drained for maintenance at a rate of 100 gallons per minute. The amount of water, w (in gallons), in the pool after t minutes is given by the function w = 45,000 – 100t. How many minutes will it take to empty the pool?

Answers

Answer:

450 minutes

Step-by-step explanation:

Given

w = 45000 - 100t

Required

Determine how long it'll take to empty the pool

Being empty means there's no water in the pool.

So, we have to set w to 0 to get the value of t

i.e w = 0

Substitute 0 for w in w = 45000 - 100t

0 = 45000 - 100t

Collect Like Terms

100t = 45000

Divide through by 100.

t = 450

Hence, it'll take 450 minutes to empty the pool

BE, CF, and AG are angle bisectors.
BE ⊥ AC, AG ⊥ BC, and CF ⊥ AB.
BE bisects AC, CF bisects AB, and AG bisects BC.
BE is a perpendicular bisector of AC, CF is a perpendicular bisector of AB, and AG is a perpendicular bisector of BC.

In the given triangle ABC, point D is orthocenter when BE ⊥ AC, AG ⊥ BC, and CF ⊥ AB.

What is an orthocenter of a triangle?

"The orthocenter is the point where all the three altitudes of the triangle cut or intersect each other."

In the given triangle ABC, to be an orthocenter, all three lines that are drawn from the points A, B, and C are must be perpendicular to the opposite side of the triangle.

Therefore,  AG must be perpendicular to BC, BE must be perpendicular to AC, and CF must be perpendicular to AB.

Option 1:

Answers

The missing reason is AAS Congruence Theorem

You can simply say AAS for short, and your teacher will likely know what you mean.

The AAS stands for Angle Angle Side. It refers to the fact how we can use two pairs of congruent angles, and a side that is not between the angles, to prove two triangles are congruent.

In this case, ABE = CDE are the two congruent 90 degree angles, and AEB = DEC are the two vertical angles

The two congruent sides are shown by the tickmarks, so AB = CD. In other words, this information is given.

Keep in mind that AAS is slightly different from ASA, so the order matters.
