Sammi wanted to create a dot plot based on this tally chart.

A 2-column table with 4 rows. Column 1 is labeled Hours with entries 3, 4, 5, 6. Column 2 is labeled Tally with entries 4, 6, 3, 5.

In which step, if any, did Sammi make a mistake creating his dot plot?

Steps to Create a Dot Plot





Step 1

Create a number line.

A number line going from 3 to 6.






Step 2

Title the Dot Plot

A number line titled How Many Hours did you read last week question mark going from 3 to 6.






Step 3

Plot the Points

A dot plot titled How Many Hours did you read last week going from 3 to 6. 3 has 4 dots, 4 has 6 dots, 5 has 3 dots, and 6 has 5 dots.

Sammi made a mistake in Step 1 because his number line did not include all numbers in the data set.
Sammi made a mistake in Step 2 because he chose a title without knowing if the table represents the number of hours read per week.
Sammi made a mistake in Step 3 because he did not correctly plot each dot above the appropriate place on the number line.
Sammi did not make a mistake.

Hello

This is a right angle as you can see by the small square at the bottom. So this means that it is 90 degrees.

Because we already know part of the 90 degrees, we can do 90-50 degree which leave us with 40 degrees.

So as we look at 8x, it needs to equal 40

- 8x=40 divide both sides by 8

- x=5

Hope this helps!

The reflection across the x-axis changes the y-coordinate to its opposite. Thus, K(1, −1) becomes K(1, 1), N(4, 0) doesn't change, and Q(4, −4) becomes Q(4, 4).

The question's task is a reflection across the x-axis. This change involves flipping the coordinates in the plane over the x-axis. For a given point with coordinates (x, y), its reflection will have coordinates (x, -y). Let's apply this rule to the points given:

K(1, −1) will become K(1, 1)

N(4, 0) will remain N(4, 0) because it lies on the x-axis

Q(4, −4) will become Q(4, 4)

So, the reflected coordinates are K(1, 1), N(4, 0), Q(4, 4).

Final answer:

The club's size decreased by a total of 27 members over 3 weeks. By dividing 27 by 3, we find that the size changed by 9 members each week.

Explanation:

The question asks about a private club which lost 27 members over the course of 3 weeks, with an equal number of members leaving each week. To find the change in the club's size each week, we divide the total number of members who left by the number of weeks. This calculation is done by taking the total decrease in members, which is 27, and dividing it by the 3 weeks.

Identify the total decrease in members: 27.

Identify the total number of weeks: 3.

Divide the total decrease in members by the number of weeks: 27 members ÷ 3 weeks = 9 members per week.

Therefore, the club's size changed by 9 members each week.

Answer:

A

Step-by-step explanation:

Since A is already in slope intercept form, we know that the b value is already in the correct place.

y = mx + b

In slope intercept form, the b is the y int.

Thank me later :)

Answer:

Option A, y = x + 4

Step-by-step explanation:

Step 1:  Determine which option is correct

y = mx + b

m is the slope while b is the y-int

So... the equation with a 4 for b should be the correct answer.

Option A states the following:  y = x + 4

This shows that the y-int is 4 and the slope is 1.  So, this answer is correct.

Answer:  Option A, y = x + 4

Answer:

41.5 cm^2

Step-by-step explanation:

The area of the right triangle is

A =1/2 bh  where b = (2+7) and h=(4+7)

  =1/2(9)(11)

    49.5

The area of the rectangle is

A = l*w  where l is 2 and w is 4

A = 2*4 = 8

The shaded region is the area of the triangle minus the area of the rectangle

A shaded = 49.5 - 8 = 41.5

Correct option B) 360 square inches .

Step-by-step explanation:

Here we have , A prism is made up of 3 rectangles and 2 triangles. A rectangle has base of 12 and height of 10. A rectangle has base of 10 and height of 13. A rectangle has base of 10 and height of 5. 2 triangles have a base of 12 inches and height of 5 inches.  We need to find What is the surface area of the prism in square inches . Let's find out:

3 rectangles and 2 triangles

A rectangle has base of 12 and height of 10 :

⇒ [tex]Area = length(width)[/tex]

⇒ [tex]Area =12(10)[/tex]

⇒ [tex]Area =120[/tex]

A rectangle has base of 10 and height of 13

⇒ [tex]Area = length(width)[/tex]

⇒ [tex]Area =13(10)[/tex]

⇒ [tex]Area =130[/tex]

A rectangle has base of 10 and height of 5

⇒ [tex]Area = length(width)[/tex]

⇒ [tex]Area =5(10)[/tex]

⇒ [tex]Area =50[/tex]

2 triangles have a base of 12 inches and height of 5 inches.

⇒ [tex]Area = \frac{1}{2}base(height)(2)[/tex]

⇒ [tex]Area =12(5)[/tex]

⇒ [tex]Area =60[/tex]

Hence , Total Area :

⇒ [tex]120+130+50+60[/tex]

⇒ [tex]360in^2[/tex]

Correct option B) 360 square inches .

Answer:

False

Step-by-step explanation:

A square is defined as a quadrilateral with 4 congruent sides, but a rectangle is defined as a quadrilateral with 2 pairs of congruent sides, so unless the 2 pairs in a rectangle are the same length, no the rectangle is not a square. However all squares are rectangles.

"A rectangle is always a square" is false statement.

A rectangle is quadrilateral, in which opposite sides are equal in length and all four angles are equal to 90 degree.

A square is quadrilateral, in which all four sides are equal in length and all four angles are equal to 90 degree.

A square is always a rectangle, but a rectangle is not always a square.

Therefore, given statements is false.

Answer:

(a)Height of the platform=40 feet

(b)Initial Velocity=54 ft/sec

(c)4 seconds

Step-by-step explanation:

The equation [tex]h(t) = -16t\² + 54t + 40[/tex] gives the height of the baton, in feet, t seconds after it is thrown from the platform.

(a)Height of the platform

The Height of the platform is the height at which t=0

[tex]h(0) = -16(0)\² + 54(0) + 40[/tex]

Height of the platform=40 feet

(b)To determine the speed at which the baton was thrown, we find the velocity, v(t).

[tex]v(t)=\frac{dh}{dt} =\frac{d}{dt} (-16t\² + 54t + 40)=-32t+54\\$At t=0\\v(0)=-32(0)+54=54 feet/sec[/tex]

(c)The baton will hit the ground when its height, h(t)=0

[tex]-16t\² + 54t + 40=0\\\text{Solving the quadratic formular}\\t = \frac{-54\pm \sqrt{(-54)^2 - 4*40*(-16)} }{2*-16}\\= \frac{-54\pm \sqrt{5476 }}{-32}\\= \frac{-54\pm 74}{-32}\\t=\frac{-54+ 74}{-32},\frac{-54- 74}{-32}\\t=-0.625\:or \:t=4[/tex]

Since -0.625 is not valid, the baton will hit the ground 4 seconds after it is thrown.

Answer:

C

Step-by-step explanation:

o find the side PQ ; we need to first find the length of the given line segment which is perpendicular to side PR; let name it as QS.

Now as ΔQSR is an right angled triangle.

and the length of the side QR and SR is given , so using Pythagorean theorem we have

QR^{2}=SR^{2}+QS^{2}

5^{2}=3^{2}+QS^{2}\\ \\QS^{2}=5^{2}-3^{2}\\\\QS^{2}=25-3=16=4^2

⇒  QS=4

Now again ΔQSP is an right angled triangle; so using Pythagorean theorem in ΔQSP we have

PQ^{2}=QS^{2}+PS^{2}\\ \\PQ^{2}=4^{2}+6^{2}=16+36=52

This means QS=\sqrt{52}=2\sqrt{13}

Hence, the length of side PQ is \sqrt{52}=2\sqrt{13}.

Hence, option C is correct.

Answer:

She earned $10 for mowing the 8th lawn.

Step-by-step explanation:

Let's use the average formula and n = 8, with x representing the 8th score:

                         12 + 10 + 15 + 15 + 15 + 10 + 9 + x

average = 12 = -------------------------------------------------

                                                  8

                                                                              86 + x

Summing up the numerator, we get average = ----------- = 12

                                                                                   8

Multiplying both sides by 8 yields                          86 + x = 96

Solving for x, we get x = 10.

She earned $10 for mowing the 8th lawn.

Answer:

She earned $10 for the eighth yard.

Step-by-step explanation:

You have 7 known numbers and 1 unknown giving you a total of 8 numbers.  When doing mean, you add up all the numbers and divide by the amount of numbers you have (in this case 8).  If you add all the numbers in this particular data set you get 86.  You know that you have to divide by 8 and you need 12 to be the answer.  Using multiplication facts, we know that 96 divided by 8 is equal to 12.  That means the answer must be 10 for the eighth yard because 86+10=96.
