Answer:
The greatest possible length of the pieces is 5 feet
Step-by-step explanation:
Red = 415 feet
Green = 780 feet
Find the greatest possible length of the pieces.
Find the Highest common factor
415 = 1, 5, 83, 415
780 = 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390 and 780
The Highest common factor of 415 and 780 is 5
The greatest possible length of the pieces is 5 feet
Red = 415/5
= 83 pieces
Green = 780/5
= 156 pieces

2+3=5cm
Step-by-step explanation:
2 and 3 would have to be added together to get the radius of the circle, resulting in the answer being 5. 2+3=5cm that's your answer
The equation of circle with center (h,k) and radius r units is
(x - h)^2 + (y - k)^2 = r^2
The equation of the circle with center (2,3) and radius 5 cm is
= (x - 2)^2 + (y - 3)^2 = 5^2
= x^2 - 4x + 4 + y^2 - 6y + 9 = 25
= x^2 + y^2 - 4x - 6y - 12 =0
hope it helps and is right

Given the data set (16 values):
8, 6, 10, 5, 7, 1, 6, 11, 5, 13, 14, 8, 11, 9, 8, 6
1. Create a histogram and a box plot to represent this data set. What is the shape of the data
representation? Explain your reasoning.
2. Which measure of center and spread would you use to represent this data? Explain your reasoning.
3. Use a random number generator to generate a set of 15 numbers between 1 and 20. Create a
histogram and box plot to represent your data set. Calculate measures of center and spread. Which
measure of center and spread would you use to represent your data?
For questions 6-9 refer to the box plots (Assume their positions are on same number line). Write your
Class A
Class B
Class C
Class D

4. Which class(es) appear to have the most consistent scores? Explain your reasoning,
Answer:
1. The shape of the histogram created with MS Excel is approximately bell shaped and approximately evenly spread about the central (largest counts) values
The shape of the box plot created with MS Excel is approximately evenly distributed
2. The appropriate measure of central tendency for a bell shaped histogram is the mean and median, due to the approximately equal distribution about the highest frequency class
3. Part A
The 15 numbers between 1 and 20 generated by a random generator are;
1, 8, 8, 15, 4, 18, 11, 6, 17, 1, 18, 15, 10, 12, 11
The measure of center is the mean = (1+8+8+15+4+18+11+6+17+1+18+15+10+12+11)/15 = 155/15 = 31/3
The measure of spread used is the variance, s² = 32.38
[tex]Where, \,s^2 =\dfrac{\sum \left (x_i-\bar x \right )^{2} }{n - 1}[/tex]
[tex]{\sum \left (x_i-\bar x \right )^{2} }[/tex] = 453.333
n = 15
s² = 453.[tex]\overline 3[/tex]/(15 - 1) = 32.38
Part B
The measure of central tendency are the mean and the median because the size of the data (n = 15), is 75% of the population (N = 20) nd therefore the data is approximately normal and can be represented by the mean and the standard deviation

What is the value of X
Answer:
x=5
Step-by-step explanation:
since this is an isosceles triangle, this means that the two base angles are equal. therefore, 8y-7=73°, meaning that y = 10° (although we don't really need to know that since you're just supposed to find x).
the angles of a triangle add up to 180°, so we can add all the angles and set them equal to 180° to find x.
6x+4+73+73=180
6x+150=180
6x=30
x=5
Solve for x
Need help asap
Answer:
[tex]x=55[/tex]
Step-by-step explanation:
Corresponding angles of two parallel lines are always equal. The angle on "top" of [tex]2x+6[/tex] corresponds with the angle marked as [tex]x+9[/tex]. Therefore, its measure must also be [tex]x+9[/tex].
Since these two angles form one side of a line which has 180 degrees, we have the following equation:
[tex]2x+6+x+9=180[/tex]
Combine like terms:
[tex]3x+15=180[/tex]
Subtract 15 from both sides:
[tex]3x=165[/tex]
Divide both sides by 3:
[tex]x=\frac{165}{3}=\boxed{55}[/tex]

If 40% of a number is equal to two-third of another number, what is the ratio of the first number to the second number.?
Answer:
5:3
Step-by-step explanation:
40% = 2/5
If the numbers are x and y, then
2/5 x = 2/3 y
Divide both sides by 2/5
x = (2/3 * 5/2)y
x = 10/6 y
x = 5/3 y
So the required ratio is 5 : 3.
Checking this result:
10% of 5 = 2
2/3 of 3 = 2 also.

The coach of a lacrosse team bought ice cream cones to celebrate a victory. A single-scoop cone was $3 and a double-scoop cone was $5 The coach bought 15 cones and paid $57. A system of equations describing this situation could be written in the form below where s represents the number of single cones andd represents the number of double cones. What is the sum of A, B, C and E?
Answer:
s=9
d=6
Step-by-step explanation:
s+d=15
3.s+5.d=57
⇒s=9 và d=6
The sum of A, B, C, and E is 23. Let's set up a system of equations based on the given information: s: number of single-scoop cones
d: number of double-scoop cones
1. The coach bought 15 cones in total:
s + d = 15
2. The cost of a single-scoop cone was $3 and the cost of a double-scoop cone was $5, and the total payment was $57:
3s + 5d = 57
Now, let's find the values of s and d by solving the system of equations.
First, we can use the first equation to solve for s in terms of d:
s = 15 - d
Now, substitute this value of s into the second equation:
3(15 - d) + 5d = 57
Now, solve for d:
45 - 3d + 5d = 57
2d = 57 - 45
2d = 12
d = 6
Now that we have the value of d, we can find the value of s using the first equation:
s = 15 - d
s = 15 - 6
s = 9
So, the number of single-scoop cones (s) is 9, and the number of double-scoop cones (d) is 6.
Now, let's find the sum of A, B, C, and E:
A: The number of single-scoop cones (s) is 9.
B: The number of double-scoop cones (d) is 6.
C: The cost of a single-scoop cone is $3.
E: The cost of a double-scoop cone is $5.
A + B + C + E = 9 + 6 + 3 + 5 = 23
So, the sum of A, B, C, and E is 23.

Bike speed of 21miles per hour. What is the speed per minute how many miles will the cyclist travel in 10 minutes
Answer:
First part: 0.35 miles per minute
Second part: 3.5 miles in 10 minutes
Step-by-step explanation:
Think about this as a fraction. Fractions can't be added nor subtracted unless they share the same denominator. So for this case, we have to turn hours into minutes. So 21 mph becomes 21 miles per 60 minutes. Then, we divide 60 from each side to find the speed per minute. 21/60 = 0.35, so the answer to the first part is 0.35 miles per minute.
Using what we got, we can answer the second part of the distance covered in 10 minutes. So, we just multiply 0.35 by 10 which is 3.5 miles covered in 10 minutes.

In the American version of the Game Roulette, a wheel has 18 black slots, 18 red slots and 2 green slots. All slots are the same size. A person can wager on either red or black. Green is reserved for the house. If a player wagers $5 on either red or black and that color comes up, they win $10 otherwise they lose their wager. What is the expected value of playing the game once
Answer:
-$0.26
Step-by-step explanation:
Calculation to determine the expected value of playing the game once
Expected value= [18/(18+18+2) x $5)]- [20/(18+18+2) x $5]
Expected value= ($18/38 x $5) - (20/38 x $5)
Expected value= ($2.37-$2.63)
Expected value= -$0.26
Therefore the expected value of playing the game once is -$0.26

Now say you invest $6,500 and the highest interest rate you can find is 2.5% compounded annually, but you would have to leave this investment in the account for a minimum of 5 years. If you decide to wait 5 years to buy the car, how much more money will you have to save to buy a car at the price of $8,000? Use the compound interest formula A = P(1 + i)^n.
A = accumulated amount
P = principle
i = interest rate
n = number of years
Answer:
$ 645.85
Step-by-step explanation:
First you would plug 6,500 into P. The plug 2.5% as 0.025 into i. And plug the years (5) into n.
A = 6500 (1 + 0.025)^5 = 7354.15
That is the amount that would be in the account at the end of the 5 years.
Then you take the cost of the car (8,000) and subtract the money left in the account (7,354.15).
8000 - 7354.15 = 645.85
Your final answer would be rounded to the nearest cent, or the hundredths place.
