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?

Answer:

12 animals per hour

Step-by-step explanation:

This is a fraction equal to

24 animals ÷ 2 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 2

24 animals ÷ 2

2 hours ÷ 2

=  

12 animals

1 hour

=  

12 animals

hour

= 12 animals per hour

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:

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

Answer:

84

Step-by-step explanation:

Multiples of 3 in this range: 63, 66, 69, 72, 75, 78, 81, 84, 87, 90, 93, 96, 99, 102, 105

Multiples of 6 in this range: 66, 72, 78, 84, 90, 96, 102

Multiples of 7 in this range: 63, 70, 77, 84, 91, 98, 105

If we look at these multiples, we see that 84 is the only number to show up in every list. Meaning, the answer is 84.

3 divided by 4 equals .75

1 / 12 = 0.08333333                Incorrect

1 / 9 = 0.11111111                         Incorrect

1 / 4 = 0. 25                              Correct

1 / 3 = 0.33333333                   Incorrect

1 / 4 is correct because .75 simplified is

.75 x 100 = 75 (75/100)

75 = 25 x 3

Answer:

[tex] - \frac{27}{7} [/tex]

Step-by-step explanation:

We want to get x alone so we need to get rid of the 7 in front of it.

7x=-27

Divide each side by 7

x= -27/7

This can't be simplified anymore so this is your answer.

Answer:

The fourth answer

Step-by-step explanation:

Answer:

{6,9}

Step-by-step explanation:

The table values are given as;

x   y

0  0

2  3

4  6

Take the values as coordinates in form of {x, y} , to have the following;

{0,0} , {2,3} , {4,6}

Find the slope using the coordinates as;

m=Δy/Δx

m=3-0/2-0 = 3/2

The slope m = 3/2

So from the answer choices, the coordinates that can give a slope of 3/2 will be:

{6,9}

The x coordinates increase by 2units while those of the y coordinates increase by 3 units.

Answer: -993/50 or -19 43/50

Step-by-step explanation:

-19.86 = -19 86/100

-19 86/100 = -19 43/50

or -993/50

Answer:

Part A: 10 ft per 2 minutes, so 5ft per 1 minute. so the slope would be -5.Part B: He would be -30ft, or 30 ft under the sea level.

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

Answer:

  (b) angle FOA

  (c) angle EOA

  (d) angle AOH

Step-by-step explanation:

(b) The rays of vertical angles are opposites that form intersecting lines.

The opposite of ray OG is OF. The opposite of ray OB is OA, so the vertical angle to GOB is angle FOA.

__

(c) The opposite of ray OB is OA, so the supplement to angle EOB is angle EOA.

__

(d) Similarly, the supplement to angle BOH is angle AOH.

_____

Comment on supplementary angles

Angles that form a linear pair are supplementary. Angles do not have to form a linear pair to be supplementary. They merely have to have a sum of 180°. Here, the supplementary angles of interest do form a linear pair, so finding the other angle of the pair means only finding the other point that names the line being formed by the pair.
