A sample of 50 11th graders were asked to select a favorite pattern out of 6 choices. The data list below shows what their favorite color patterns were, and the accompanying frequency table and bar graph represent these data. In the bar graph, the height of the blue gray bar is 4, the height of the green bar is 9, and so on. Suppose that rather than being just a bar graph, the display you see above is a relative frequency bar graph. The vertical axis of the graph will be marked off in percentages, from 0 percent up to 30 percent. What will be the height of the green bar? A. 18 B. 9 C. 25 D. 15

A Sample Of 50 11th Graders Were Asked To Select A Favorite Pattern Out Of 6 Choices. The Data List Below

Answers

Answer 1

Answer:

18

Step-by-step explanation:

Answer 2

The required height of the green bar is 18. Option A is correct.

Number of sample = 50
Height of the green bar is = 9

What is Statistic?

The statistic is the study of mathematics which deal with relations between static data.

Here,
Percentage of green bar on vertical axis = 9/50 x 100
                                                                     =  9 x 2
                                                                     =   18%

Thus. the required height of the green bar is 18.

Answers

Answer:

90 degrees

Step-by-step explanation:

For this problem we will use our knowledge about the Interior Angle to Circle Theorem.

∡EGC=(arcEC+arcDF)/2

arcEC+arcDF=70°*2

5x+10+11x+2=140

16x+12=140

16x=128

a motor racing has a length of 5 5/6 a straight section of a circuit has a length 1 1/4 miles what fraction of the circuit is the straight section ? give your answer in the simplest form

Answers

Answer:

[tex]Fraction = \frac{3}{14}[/tex]

Step-by-step explanation:

Given:

[tex]Total\ Length = 5\frac{5}{6}[/tex]

[tex]Straight\ Section = 1\frac{1}{4}[/tex]

Required:

Fraction of the circuit that is straight section

To solve this, we simply divide the length of the straight section by the total length of the circuit;

This is done as follows;

[tex]Fraction = 1\frac{1}{4} / 5\frac{5}{6}[/tex]

Convert both fractions to improper fractions

[tex]Fraction = \frac{5}{4} / \frac{35}{6}[/tex]

Change division sign (/) to multiplication (*)

[tex]Fraction = \frac{5}{4} * \frac{6}{35}[/tex]

Combine to form a single fraction

[tex]Fraction = \frac{5*6}{4*35}[/tex]

[tex]Fraction = \frac{30}{140}[/tex]

Divide numerator and denominator by 10

[tex]Fraction = \frac{3}{14}[/tex]

Hence, the fraction of the straight section is; [tex]Fraction = \frac{3}{14}[/tex]

Step-by-step explanation:

f(x)=(x+3)^3

The parent function is

g(x) = x^3

The function was shifted to the left 3 units from the parent function

f(x) = ( x- -3) ^3

f(x) = ( x+3) ^3

(parent function) f(x) = (x+3)3

What is the area of it?

Answers

Answer:

12 ft²

Step-by-step explanation:

The figure is composed of 2 triangles.

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

A of upper triangle = [tex]\frac{1}{2}[/tex] × 4 × 3 = 2 × 3 = 6 ft²

A of lower triangle = [tex]\frac{1}{2}[/tex] × 4 × 3 = 2 × 3 = 6 ft²

Thus

area of figure = 6 + 6 = 12 ft²

A ticket for a seat at a village parish play costs £3.95 There are 17 rows of seats. There are 29 seats in each row. The village parish will sell all the tickets. Work out an estimate for the total money the village parish will get. Explanation:

Answers

Answer:

Total money earned = £1,947.35

Step-by-step explanation:

Given:

Per ticket cost = £3.95

Number of rows = 17

Number of seats in each row = 29 seats

Find:

Total money earned.

Computation:

Total number of seats = Number of rows × Number of seats in each row

Total number of seats = 17 × 29

Total number of seats = 493 seats

Total money earned = Total number of seats × Per ticket cost

Total money earned = 493 × £3.95

Total money earned = £1,947.35

Answers

I chose a box of cereal-------> rectangular prism

Part 1)List the dimensions of your box. Be sure to include the units (in, cm, ft, etc.).

Length: 20 cm

Width: 8 cm

Height: 32 cm

Part 2).

 Describe the shape of the cross-section when the box is cut parallel to the base

the shape of the cross-section would be a rectangle of dimensions

20 cm x 8 cm

Part 3)

What is the surface area of the box? 

surface area=2*area of the base+perimeter of the base*height

area of the base=20*8=160 cm²

perimeter of the base=2*[20+8]-----> 56 cm

height=32 cm

surface area=2*160+56*32------> 2,112 cm²

the answer part 3) is

2,112 cm²

Part 4)

What is the surface area of the box if it is scaled up by a factor of 10?

we know that

surface area of the larger box=[scale factor]²*surface area original box

scale factor=10

surface area original box=2,112 cm²

so

surface area of the larger box=10²*2,112-----> 211,200 cm²

the answer part 4) is

211,200 cm²

Part 5) 

What is the volume of the box?

volume of the box=L*W*H-----> 20*8*32------> 5,120 cm³

the answer Part 5) is

5,120 cm³

Part 6) 

What is the volume of the box if it is scaled down by a factor of 1/10

we know that

the volume of the smaller box=[scale factor]³*volume original box

scale factor=1/10

volume original box=5,120 cm³

so

volume of the smaller box=[1/10]³*5,120-----> 5.12 cm³

the answer part 6) is

5.12 cm³

The length is⇒ 6 in., the width is⇒ 2 in., and the height is⇒ 16 in.

Answers

Answer:

x-intercept is equal to 2 (Option 3)

Step-by-step explanation:

Slope = m = -3/2

y-intercept = b =  3

Putting in the slope-intercept form

=> y = [tex]\frac{-3}{2} x+3[/tex]

For finding x- intercept, y must be equal to 0

=> 0 = (-3/2)x+3

Answer:

C.) Number of successful trials / Total number of trials

Step-by-step explanation:

The empirical probability of an event 'E' is defined as :

(Number of successful occurrences of event 'E' / Total number of trials)

The empirical probability requires that an experiment of a chosen number of trials be performed. The ratio of the number of success to the total number of trials is used to estimate the empirical probability of such event.

P(Empirical) = (Number of successful trials / Total number of trials)

This is different from the use of sample space in the evaluation of theoretical probability whereby all possible occurences is used to estimate the probable outcome of an event.

P(theoretical) = (number of required outcomes / total number of possible outcomes)

Answer:

A person in a group where 5 people are sharing 3 small bags of snickers

Step-by-step explanation:

Let the number of calories in one bag of snickers =x

Number of calories in 3 small bags of snickers =3x

If 5 people share 3 small bags of snickers, 1 person's share  [tex]=\dfrac{3x}{5}[/tex]

Number of calories in 2 small bags of snickers =2x

If 7 people share 2 small bags of snickers, 1 person's share  [tex]=\dfrac{2x}{7}[/tex]

We then compare the two.

Let x=1

[tex]\dfrac{3}{5}=0.6$ calories per person\\\dfrac{2}{7}=0.29$ calories per person[/tex]

Therefore, a person in a group where 5 people are sharing 3 small bags of snickers gets more calories.

3(x+1)=2(x-1) solve for x

Answers

Answer:

x = -5

Step-by-step explanation:

3(1 + x) = 2(x + -1)

(1 * 3 + x * 3) = 2(x + -1)

(3 + 3x) = 2(x + -1)

Reorder the terms:

3 + 3x = 2(-1 + x)

3 + 3x = (-1 * 2 + x * 2)

3 + 3x = (-2 + 2x)

Solving :the equation

3 + 3x = -2 + 2x

add '-2x' to each side of the equation.

3 + 3x + -2x = -2 + 2x + -2x  

Combine like terms: 3x + -2x = x

3 + x = -2 + 2x + -2x

combine like terms: 2x + -2x = 0

3 + x = -2 + 0

3 + x = -2

Add '-3' to each side of the equation.

3 + -3 + x = -2 + -3

Combine like terms: 3 + -3 = 0

0 + x = -2 + -3

x = -2 + -3  

Combine like terms: -2 + -3 = -5

x = -5  

divide each side by '1'.

x = -5

x=-5
3(x+1)=2(x-1)
3x+3=2x-2

A sporting goods store receives a shipment of 124 golf bags. The shipment includes two types of bags, full-size and collapsible. The full-size bags cost $38.50 each. The collapsible bags cost $22.50 each. The bill for the shipment was $3430. How much of each type of golf bag should be in the shipment? Show all work and verify your answer (prove that your answer is correct)

Answers

The sporting goods store receives the shipment of 124 golf bags in total.

Let us assume that the number of full-sized bags = X

Then the number of collapsible golf bags = 124 - X

Cost of each full sized bags = $38.50

Cost of each collapsible bags = $22.50

Total cost of the 124 bags received by the sporting goods store = $3430

Then

(38.50)X + (124 - X)22.50 = 3430

(38.50X - 22.50X) + 2790 = 3430

16X = 3430 - 2790

16X = 640

X = 640/16

  = 40

So the number of full-sized golf bags received = 40

Then the number of collapsible golf bags received = 124 - 40

                                                                                = 84
