Find the median and mean of the data set below:
21,0,36,30,13,32
Answer:
Mean: 22
Median: 25.2
Step-by-step explanation:
The mean is the sum of all the numbers in a set divided by the number of terms in a set.
The median is the middle value of the numbers when the numbers in a set are arranged from least to greatest. If there is two middle numbers, the median is the average of the two numbers.

Answer:
m∠BFE = 171º
BE = 219º
Step-by-step explanation:
∠BFE is supplementary to ∠EFC
m∠BFE = 180 - 9
m∠BFE = 171º
--------------------------
The angle between two chords is equal to half the sum of the intercepted arcs:
∠BFE = (DC + BE)2
171 = (123 + BE)/2
342 = 123 + BE
219º = BE

Find the circumference of the object. Use $3.14$ or $\frac{22}{7}$ for $\pi$ . Round to the nearest hundredth if necessary.
Answer:
18.84 units
Step-by-step explanation:
The question is incomplete, however, we can proceed with the given information
Given data
The expression for the circumference of a circle is given as
C= 2πr
Hence when we have a value for the radius say r= 3
Hence the circumference can be found as
C= 2*3.14*3
C= 18.84 units

The cereal box shown below is a rectangular prism.
Answer:
Surface area is found:
Surface Area = 1700 cm²
Step-by-step explanation:
(The cereal box is shown in the ATTACHMENT)
The surface area of a rectangular prism can be found by added the areas of all 6 sides of the rectangular prism.
L = length = 20 cm
H = height = 30 cm
W = Width = 5 cm
Side 1:
A(1) = L×H
A(1) = 20×30
A(1) = 600 cm²
Side 2:
As the measurements of the side at the back of side 1 has the same measurement of side 1. then:
A(2) = 600 cm²
Side 3:
A(3) = L×W
A(3) = 20×5
A(3) = 100 cm²
Side 4:
As the measurements of the side at the back of side 4 has the same measurement of side 4. then:
A(4) = 100 cm²
Side 5:
A(5) = H×W
A(5) = 30×5
A(5) = 150 cm²
Side 6:
As the measurements of the side at the back of side 5 has the same measurement of side 5. then:
A(6) = 150 cm²
Surface Area:
Adding areas of all the sides
A(1) + A(2) + A(3) +A(4) + A(5) + A(6) = 600 + 600 + 100 +100 + 150 +150
Surface Area = 1700 cm²

So far this semester, Brian is averaging a score of 63 points on math tests, which is 10% lower than his average last semester. What was the average of his scores last semester?
Answer:
Step-by-step explanation:
So far this semester, What was the average of his scores last semester?
Let us represent last semester average score as x
We are told that:
Brian is averaging a score of 63 points on math tests, which is 10% lower than his average last semester.
This is expressed Mathematically as:
63 = x - 10%
63 = x - 0.1
Collect like termd
x = 63 + 0.1
x = 63.1

A rectangle has a side length of 2x and a diagonal of 8x. What is the missing lenght?
Answer:
2x[tex]\sqrt{15}[/tex]
Step-by-step explanation:
we can use the Pythagorean Theorem to find the missing side (a):
a² + (2x)² = (8x)²
a² + 4x² = 64x²
a² = 60x²
a = √60x²
a = [tex]\sqrt{4}[/tex]·[tex]\sqrt{15}[/tex] · [tex]\sqrt{x^2}[/tex]
This can be simplified to be 2x[tex]\sqrt{15}[/tex]

a point in rectangular coordinates is given. Convert the point to polar coordinates. Round your answers to two decimal places.
(5,7)
Answer:
(√74, 54.46°)
Step-by-step explanation:
The rectangular coordinate point is given as; (5, 7)
Now, converting rectangular coordinates to polar coordinates is done by;
(r, θ)
Where, r is the magnitude while θ is the angle
r = √(5² + 7²)
r = √74
tan θ = (7/5)
θ = tan^(-1) 1.4
θ = 54.46°
Thus,polar coordinate is; (√74, 54.46°)

The latest online craze is a new game, Khan on Seven. You get 100 points for playing the game. In addition, you get 50 points for each seven-letter word you make with the ten letters you receive. Sal wants to break the record, and he needs 18000 or more points to do so.
Write an inequality to determine the number of seven-letter words, w Sal could make to break the record.
Answer:
Answer: 50x+100\geq18,00050x+100≥18,000
Let w denotes a seven letter word which Sal will need to make to break the record.
Since you get 50 points for each seven-letter and 100 points for playing the game.
Then the total points earned by you by making w seven letters words will be:
50x+10050x+100
Since, Sal wants to break that record, and needs 18,000 points or more to do so.
Then , the required inequality will be :
50x+100\geq18,00050x+100≥18,000

help finding the circumference
Answer:
approximately equal to 72 centimeters
Step-by-step explanation:
The formula for the circumference of a circle is 2[tex]\pi[/tex]r.
The formula for finding the radius with an arc and an arc length is 180 times l over [tex]\pi[/tex] times the angle.
[tex]\frac{3420}{298.45}[/tex] which is approximately equal to 11.46
11.46 is our radius so the circumference is 2[tex]\pi[/tex](11.46) or about 72

Which statements about liquid volume are true?
Select each correct answer.
One milliliter is 100 times smaller than one liter.
Liters are smaller units than milliliters.
Milliliters are smaller units than liters.
One liter is 1,000 times larger than one milliliter.
One milliliter is 100 times larger than one liter.
One liter is 1,000 times smaller than one milliliter.
Answer:
C, D
Step-by-step explanation:
These are the only correct statements about liquid volume. 1L= 1,000mL
A Liter is larger than a mL, a thousand times so.
A mL is smaller than a Liter, a thousand times so.
The correct statements about liquid volume are:
1. One milliliter is 100 times smaller than one liter.
2. Milliliters are smaller units than liters.
3. One liter is 1,000 times larger than one milliliter.
1. One milliliter is 100 times smaller than one liter:
This statement is true.
Since there are 1,000 milliliters in one liter, dividing one liter by 1,000 gives us the equivalent value of one milliliter.
2. Milliliters are a smaller unit of measure compared to liters. There are 1,000 milliliters in one liter, so any given volume in milliliters will be a fraction of the equivalent volume in liters.
3. As mentioned earlier, there are 1,000 milliliters in one liter.
Therefore, one liter is 1,000 times larger than one milliliter.
4. Liters are larger units of measure compared to milliliters.
5. As explained earlier, one milliliter is 100 times smaller than one liter.
