Answer:

The measure of an interior angle of a regular 12-gon is 150°.

Hence, option 'C' is correct.                          

Step-by-step explanation:

We need to determine the measure of an interior angle of a regular 12-gon.

Thus,

Using the formula to determine the measure of an interior angle of a regular 12-gon is given by

(n - 2) × 180° = n × interior angle

substitute n = 12

(12 - 2) × 180 = 12 × interior angle

10 × 180 = 12 × interior angle

Interior angle = (10 × 180) / 12

                      = 1800 / 12

                      = 150°

Therefore, the measure of an interior angle of a regular 12-gon is 150°.

Hence, option 'C' is correct.

Answer:

Option B, C, and D

Step-by-step explanation:

This is the complete question below;

The ratio of pages read to minutes for Hang is 5 : 8. Who has a greater ratio of pages read to minutes than Hang? Select all that apply. A. Kira:2 pages read every 4 minutes B. Joe:6 pages read every 9 minutes C. Quon:5 pages read every 7 minutes D. Lulu:10 pages read every 13 minutes E.

EXPLANATION:

We are given, The ratio of pages read to minutes for Hang as 5 : 8. Which means 5/8= 0.625, then we can say he read 0.625 of a page per minute.

Let us do this for each of the given options;

A. Kira:2 pages read every 4 minutes

Kira's rate= 2/4= 0.5page per minute.

B. Joe:6 pages read every 9 minute

Then Joe's rate = 0.667page per minute.

C. Quon:5 pages read every 7 minute

Quon's rate = 5/7 = 0.7143page per minute.

D. Lulu:10 pages read every 13 minutes

Lulu's rate= 10/13= 0.76923page per minute.

Those that that has a greater ratio of pages read to minutes than Hang are

Joe(0.667page per minute)

Quon( 0.7143page per minute)

and Lulu (0.76923page per minute.)

Because their rate is higher than HANG(0.625 of a page per minute.)

Answer:

The answer is A

Step-by-step explanation:

Answer:

C. The mean for brand B is higher than brand A.

Step-by-step explanation:

What we're looking for is the true statement of these 4.

We already know B is out, because there were 11 lightbulbs on brand B, and 10 on brand A.

Because of that, A is also out, because the means cannot be the same.

As a result, only C and D remain.

Now, add the 10 dots on brand A.

((1000 * 1) + (1100 * 2) + (1200 * 3) + (1300 * 4))/10

(1000 + 2200 + 3600 + 5200)/10

(3200 + 3600 + 5200)/10

(6800 + 5200)/10

12000/10

Brand A has an average of 1200 hours/lightbulb

Then, add the 11 on brand B

((1400 * 1) + (1500 * 4) + (1600 * 2) + (1700 * 1) + (1800 * 1) + (1900 * 1))/11

(1400 + 6000 + 3200 + 1700 + 1800 + 1900)/11

(7400 + 3200 + 1700 + 1800 + 1900)/11

(10600 + 1700 + 1800 + 1900)/11

(12300 + 1800 + 1900)/11

(14100 + 1900)/11

16000/11

Brand B has an average of 1454 hours 27 minutes 16 seconds 364 milliseconds/lightbulb

Comparing the two averages, we come to the realization that D is out because Brand A's average was less than Brand B's.

That leaves C as our answer.

Step-by-step explanation:

Answer:

False

Step-by-step explanation:

It is given that Noah thinks :

9x - 2x + 4x = 3x   as the subtraction sign after 9x tells us to subtract everything that comes after 9x.

This is wrong as according to the BODMAS rule, we have to do the addition operation first and then followed by subtraction operation.

That is

⇒ 9x - 2x + 4x

⇒ (9x -2x)+ 4x

⇒ 7x + 4x

⇒ 11x

Therefore the answer to the equation is 11x and not 3x.

Answer:

The car will travel 1980 meters in 15 minutes.

Hence, option 'D' is true.

Step-by-step explanation:

Given that a car travels 300 meters in the first minute, so

Each minute after, the car travels 120 meters. , so the sequence becomes

a₁, a₂, a₃, a₄, a₅, ...

300, 420, 540, 660, 780, ...

An arithmetic sequence has a constant difference 'd' and is defined by  

[tex]a_n=a_1+\left(n-1\right)d[/tex]

computing the differences of all the adjacent terms

[tex]20-300=120,\:\quad \:540-420=120,\:\quad \:660-540=120,\:\quad \:780-660=120[/tex]

The difference between all the adjacent terms is the same and equal to [tex]d=120[/tex]

now, we have

so substituting a₁ = 300 and d = 120 in the nth term of the sequence

[tex]a_n=a_1+\left(n-1\right)d[/tex]

[tex]a_n=120\left(n-1\right)+300[/tex]

[tex]a_n=120n+180[/tex]

Thus, the nth term of the sequence is:

[tex]a_n=120n+180[/tex]

Determining the distance the car travels in 15 minutes

As we have already determined the nth term of the sequence such as

[tex]a_n=120n+180[/tex]

now substituting n = 15

[tex]a_{15}=120\left(15\right)+180[/tex]

[tex]a_{15}=1800+180[/tex]

[tex]a_{15}=1980[/tex]

Therefore, the car will travel 1980 meters in 15 minutes.

Hence, option 'D' is true.

Answer: He bought 4 pastries.

Step-by-step explanation:

Let x = Number of cups of coffee

y= Number of pastries.

As per given,

x+y=9            ....(i)

2.5x+4y=28.50           ...(ii)

Multiply 4 to (i), we get

4x+4y=36   ...(iii)

Eliminate (ii) from (iii), we get

[tex]1.5x=7.5\\\\\Rightarrow\ x=5[/tex]

Put x=5 in (i) , we get

5+y=9

y= 4

Hence, He bought 4 pastries.

Answer: 6 guides

Step-by-step explanation:

Question wants to know the number of Guides present on Sunday.

On Saturday there were 120 tourists and 18 guides. The ratio was therefore:

120 : 18

On Sunday, the ratio must be the same and there are 40 tourists. You can solve this using direct proportion and multiplying:

120 : 18

40   :  x

120x = 18 * 40

x = 720/120

x = 6 guides

The correct description about median is class median is lower than the exam median.

An illustration of variation in a set of data is called a box and whisker plot. A histogram analysis usually gives an adequate display, but a box and whisker plot can add more detail while enabling the display of different sets of data on the same graph.

We have,

Box plot 1:

Minimum= 70

Q1 = 74

Median = 83

Q3 = 92

Maximum = 100

Box plot 2:

Minimum= 60

Q1 = 81

Median = 87

Q3 = 91

Maximum = 95

So, the class median is lower than the exam median.
