Seven students in class A and ten students in class B ate pizza. There are 25 students in class A and 30 students in class B. What fraction of the class didn't eat pizza?

Answer:

you would be correct in the second option, unknown

Step-by-step explanation:

anonymous is another word for unknown, i learned this in gamer talk ;P

Answer: Unknown.

Step-by-step explanation: When any author is anonymous whether they write myths, legends, short stories, etc, it means that their name is hidden or unknown.  If you looked it up online, it would tell you this, "(of a person) not identified by name; of unknown name."  Therefore, anonymous means an author not identified who is unknown.

Answer:

B.

Mean: 16.1

Median: 16

Mode: 16

Step-by-step explanation:

First, order the numbers in the data set from least to greatest:

[tex]14 , 14 , 14 , 14 , 15 , 15 , 15 , 15 , 15 , 16 , 16 , 16 , 16 , 16 , 16 , 17 , 17 , 17 , 19 , 19 , 19 , 19[/tex]

First, find the mean. The mean of a data set can be found by adding all the numbers together and dividing by the amount of numbers in the set:

[tex]\frac{14 + 14 + 14 + 14 + 15 + 15 + 15 + 15 + 15 + 16 + 16 + 16 + 16 + 16 + 16 + 17 + 17 + 17 + 19 + 19 + 19 + 19}{22} = \frac{354}{22}[/tex]

Next, simplify by dividing:

[tex]\frac{354}{22} = \frac{177}{11} = 16 \frac{1}{11} or ~16.1[/tex]

Mean: 16.1

Next, find the median. The median is the number(s) directly in the middle. If there is a even amount of number in the data set, find the mean of the two median numbers:

Median: 16 , 16

Median = [tex]\frac{16 + 16}{2} = \frac{32}{2} = 16[/tex]

Median = 16

Next, find the mode. The median is the number that shows up the most. In this case, it is 16, which appears 6 times, 1 more time then the next number that appears the most 15, which appears 5 times.

Mode: 16

If you are asked about range, range would be the greatest digit value subtracted by the least digit value. In this case, it would be 14 & 19:

19 - 14 = 5

Range: 5

~

Step-by-step explanation:

The centroid O cuts every median in the ratio 2:1. The distance between a vertex and the centroid is twice the distance between the centroid and the midpoint of the opposite side.

Therefore: |OD| = 2|OCI

Answer:

108m

Step-by-step explanation:

2 sides are 30m long and 2 sides are 24m long.

Add all 4 sides of the playground to find the perimeter.

30m + 24m + 30m + 24m = 108 m

Using proportions, it is found that:

A proportion is a fraction of a total amount.

Item a:

The sum of the frequencies is of 1, hence, the table is completed with 1 - (0.55 + 0.35) = 0.1.

Item b:

Considering that there were n games, we have that:

The difference was of 15, hence:

0.55n - 0.35n = 15

0.2n = 15

n = 15/0.2

n = 75

The team played 75 games.

Answer:

Step-by-step explanation:

In the question we have given volume of Sphere that is 562.5 π in³ and we have asked to find the radius of given sphere. We know that the volume of sphere ,

[tex] \blue{ \boxed{ \rm{Volume \: of \: Sphere = \frac{4}{3} \pi r {}^{3} }}}[/tex]

So equating it with given volume for finding the radius of sphere :

[tex] \longmapsto \: \frac{4}{3} \pi r{}^{3} = 562.5\pi[/tex]

Step 1 : Cancelling π as it was present in both side :

[tex]\longmapsto\:\frac{4}{3} \cancel{\pi }r{}^{3} = 562.5 \cancel{\pi}[/tex]

Step 2 : Transposing 4/3 to right hand side :

[tex]\longmapsto \: r {}^{3} = 562.5 \times \frac{3}{4} [/tex]

Step 3 : Multiplying 562.5 with 3 :

[tex]\longmapsto \:r {}^{3} = \frac{1687.5}{4} [/tex]

Step 4 : Dividing 1687.5 by 4 :

[tex]\longmapsto \:r {}^{3} = 421.875[/tex]

Step 5 : Finding cube root of 421.875

[tex]\longmapsto \:r = \sqrt[3]{421.875} [/tex]

Step 6 : We get :

[tex]\longmapsto \: \red{ \boxed{r = 7.5}}[/tex]

Answer:

Step-by-step explanation:

Factors of 21: 1, 3, 7, and 21

Factors of 64: 1, 2, 4, 8, 16, 32, and 64

These numbers do not share any other factors other than 1

Answer:

First, the student performed what was inside of the parentheses and was exponential, which is correct. We know this because of the rules called order of operations, outlined by PEMDAS, which tells us to perform mathematical operations in the following order: parentheses, exponents, multiplication, division, addition, subtraction.

So by the rules I just outlined, next the student should have performed the multiplication, but instead performed subtraction, which is incorrect.

The following is the correct simplification of the expression:

23 - 8 times 2 + 3 by the power of 2

So first we should perform parentheses, but there are none. So we move to the next option in the list, which is exponents, which we do have (3^2).

23 - 8 * 2 + 3^2

23 - 8 * 2 + 9

Next in PEMDAS comes multiplication and division. This means the next step in simplifying the expression is to evaluate 8*2.

23 - 16 + 9

Next in PEMDAS is addition, so we should perform the operation -16 + 9.

23 - 7

Finally, the last step in PEMDAS is to simplify the remaining operation (subtraction).

16

Therefore, the student did the first step correctly but performed the second step incorrectly. The final answer should be 16 after simplification.

Hope this helps!

Answer:

y<7

Step-by-step explanation:

3y-10 < 11     add 10 to both sides of the equation

3y < 21      divide by 3

y < 7

To find the slope between two points:

 ⇒ must know the slope's formula

            [tex]\frac{y2-y1}{x2-x1}[/tex]

Let's consider the information given

  ⇒ given two points ⇒ (4, -6) and (-3,1)

          (x1, y) --> (4, -6)

          (x2, y2) --> (-3, 1)          

Let's calculate the slope:

  [tex]slope = \frac{1--6}{-3-4} =\frac{7}{-7} =-1[/tex]

Thus the slope is -1
