1. Can you explain how a table can be used to find the rate of change?
2. How do you find the rate of change using a graph?
Answers
x y
1 2
2 4
And so on. The rate of change for that table would be every time the x axis goes up 1, the y axis goes up 2.
2. To find the rate of change using a graph, look at the line on the graph. You can make a small triangle that starts on the line and then comes out and re-connects into the line. Like so - (look at attached picture). And as you go, you count how many you go down or up and how many you go left or right.

Find the outlier of the set of data: 24, 37, 33, 31, 28, 25, 33, 12
Answers
The outlier is therefore 12, because it is not in the general range of values, which is on average around 29.
Answer:
The outlier of the set is 12.
Step-by-step explanation:
Consider the provided set of data:
4, 37, 33, 31, 28, 25, 33, 12
The outlier is a kind of data which is abnormal distance from the other points.
Or the data that lies outside the other value in the provided set.
Now consider the data.
12 is lies outside the other values because the distance is abnormal.
The number 12 is not close to any of the other numbers.
Hence, the outlier of the set is 12.

If 365 work days are split among 12 employees evenly
PART: A How can you rewrite this as a fraction?
PART:B What does the fraction represent?
Answers
Part A: To understand this question, you need to read carefully and pick out key words that tells you what to do. All math word / puzzle problems have key words that tell you what you need to do.
For instance, the key word split tells us we need to divide. So, we know we have 365 work days that need to be split among 12 employees. So for Part A:
365 / 12
For Part B it wants to know what this represents. It represent the number of days each of the 12 employees will get if split evenly among each employee.

Vincent is giving cakes to some children at a carnival. He has 2 strawberry cakes, 6 pineapple cakes, and 7 chocolate cakes. If Vincent selects a cake randomly without looking, what is the probability that he will give a pineapple cake to the first child and then a strawberry cake to the second child? (5 points)
6 over 15 multiplied by 2 over 14 is equal to 12 over 210
6 over 15 plus 2 over 14 is equal to 114 over 210
6 over 15 multiplied by 2 over 15 is equal to 12 over 225
6 over 15 plus 2 over 15 is equal to 8 over 15
Answers
2+6+7 = 15 total cakes
6 pineapple so probability is 6/15
then there would be 14 cakes
2 strawberry for a probability of 2/14
6/15 x 2/14 = 12/210
the first answer is the right one
Answer:
[tex]\frac{12}{210}[/tex]
Step-by-step explanation:
Strawberry cakes = 2
Pineapple cakes = 6
Chocolate cakes = 7
Total cakes = 15
Now we are given that Vincent selects a cake randomly without looking, and he will give a pineapple cake to the first child
So, probability of getting a pine apple cake in first draw = [tex]\frac{\text{No. of pineapple cakes}}{\text{Total no. of cakes}}[/tex]
= [tex]\frac{6}{15}[/tex]
Now total no. of remaining cakes = 15-1 =14
Now we are given that Vincent selects a cake randomly without looking, and he will give a strawberry cake to the second child
So, So, probability of getting a strawberry cake in second draw= [tex]\frac{2}{14}[/tex]
So, the probability that he will give a pineapple cake to the first child and then a strawberry cake to the second child = [tex]\frac{6}{15} \times\frac{2}{14} [/tex]
= [tex]\frac{12}{210}[/tex]
Hence Option A is true.
The probability that he will give a pineapple cake to the first child and then a strawberry cake to the second child is [tex]\frac{12}{210}[/tex]
Rita bought fabric and ribbon from a store the ribbon cost $18.50 rita paid the cashier $50.00 and received change of $5.25 how much did the fabric cost
Answers
2. I know this because...
- First, I subtracted the cost of the ribbon from how much she paid.
· Equation: $50.00 - $18.50 = $31.50
- Second, I subtracted the change received by the reduced cost ($31.50)
· Equation: $31.50 - $5.25 = $26.25
3. So, the final amount of money Rita spent on fabric is $26.25.

A regular pentagonal prism has a height of 14 in. and a base edge length of 10 in. Identify its lateral area and surface area.
Can anyone help me solve this?
Answers
So the lateral area = 5 * 10 * 14 = 700 (in squared)
Consider one of the bases of the prism.
As shown in the figure, the pentagon is made up of 5 isosceles triangles.
The vertex of each of these 5 triangles is 360°/5=72°.
Draw the altitude, which forms 2 right triangles with angle measures 36°-54°-90°.
Let he hypotenuse be s and the altitude be h in, as shown in the figure.
x*cos54°=5
x=5/(cos54°)=5/(0.588)=8.5
then,
h=x*sin54°=8.5*(0.8)=6.8 (in)
Thus, the area of one of the 5 congruent isosceles triangles is
[tex] \frac{1}{2}*10*6.8= 34[/tex] (in squared)
The area of the pentagonal base is 34*5 = 170 (in squared)
Thus the surface area = lateral area + 2 base area
= 700+2*170 = 700+340 = 1040 (in squared)
Answer:
lateral area: 700 in squared
surface area: 1040 in squared
Answer:
L = 700 in2 ; S = 1044.1 in2

The singing club keeps sheet music in files. Each file holds 12 sheets. Of all the club's music, 2/3 fit into 3 files. How many sheets of music does the club have?
Answers
Now for 3 files -> 3*12 = 36 sheets, it takes up 2/3 of the total
So the total number of sheets: 36 / (2/3) = 54
The singing club has a total of 36 sheets of music.
Explanation:To find the total number of sheets of music the club has, we can set up a proportion using the given information. Since 2/3 of the club's music fits into 3 files, this means that 1/3 of the music fits into 1 file. So, if 1/3 represents 12 sheets, then 1 represents 12 * 3 = 36 sheets. Therefore, the club has a total of 36 sheets of music.

which of the following best describes a regular polygon when the sum of its interior angles is 1080 degrees A.) octagon B.) heptagon C.) hexagon D.) nonagon
Answers
1080= (n-2)180
1080/180=6
6=(n-2)
n=8
(This is the formula for finding the sum of interior angles in polygons. n represents the number of sides in the polygon)
Answer:
Option A is correct.
Step-by-step explanation:
Given: Sum of all the interior angles of a regular polygon = 1080°
To find: number of sides or name of polygon.
We know that Sum of all interior angle of a regular polygon is given by following formula,
Sum of all angles = ( n - 2 ) × 180° , where n = no of sides.
⇒ 1080° = ( n - 2 ) × 180°
n - 2 = 6
n = 6 + 2
n = 8
Name of regular polygon is Regular Octagon.
Therefore, Option A is correct.

Jeff takes 20 mins to jog around the race course one time. And 25 mins to jog arpund second time. What is his average speed in kms per hr fpr the whole jog if the course is 3 kms long?
Answers
Work=Rate*Time, or Distance=Speed*Time.
Thus, the time is: [tex]speed= \frac{distance}{time} [/tex].
In our problem, the total distance is 3 km + 3 km = 6 km.
the total time is 20 min + 25 min = 45 min.
60 minutes are 1 hour, then
45 minutes are [tex] \frac{45min*1h}{60min}= 0.75h[/tex]
Thus, the average speed is : distance/time = 6 km/ 0.75 h = 8 km/h

Answers
xyz = (x)(y)(z)
if x, y and z are perfect cubes, then xyz would also be a perfect cube
Also,
(x^n)^m = x^(mn)
if it is a perfect cube, then it can be factored into the expression (x^n)^3, wherein n is a whole number.
All should be a perfect cube, given
215x^18(y^3)(z^21)
By writing the terms separately, we would see which one is to be changed.
215 = 5*43, we see this is not a perfect cube, we could changed it to 6^3 or 216
x^18=(x^6)^3
y^3=y^3
z^21=(z^7)^3
The other terms are perfect cubes except for the first one. So the correct answer would be the last option, 215 should be changed.
