WILL GIVE BRAINLIEST! Alice, Bob, and Carrie can all choose a number from 1 to 10 (inclusive).
(a) Find the number of ways they can choose their numbers if all three numbers are different.
(b) Find the number of ways they can choose their numbers if they have to choose exactly two different numbers among all three people. (For example, Alice and Bob both pick 1, and Carrie picks 2.)
Answer:
(a) 720
(b) 180
Step-by-step explanation:
We are given 10 numbers (1,2,3,4,.....,10).
(a) 3 unique numbers are to be chosen by Alice, Bob and Carrie.
Number of ways to choose the 1st number = 10
Number of ways to choose the 2nd number = 9 (1 number chosen earlier can't be chosen again)
Number of ways to choose the 3rd number = 8 (2 numbers chosen earlier can't be chosen again)
Total number of ways of choosing 3 unique numbers = [tex]10 \times 9 \times 8 \Rightarrow 720[/tex]
(b)
Number of ways of choosing 1st number = 10 (no restrictions)
Number of ways of choosing 2nd number = 9 (1 number chosen earlier can't be chosen again)
Now, restriction on the 3rd number to be chosen is that one of the two already chosen number should be chosen again.
So, number of ways to choose 3rd number = 2
the number of ways they can choose their numbers if they have to choose exactly two different numbers among all three people =
[tex]10 \times 9 \times 2 \Rightarrow 180[/tex]
Hence, the answers are:
(a) 720
(b) 180

Answer:
20 ft² - 4ft² = 16 ft²
Step-by-step explanation:
First we solve for the whole rectangle:
Formula: A = ab
side length a = 5 in
side length b = 4 in
diagonal p = q = 6.4031242374328 in
perimeter P = 18 in
area A = 20 in²
Second we deduct the Area of the cutout of the Square
side length a = 2 ft
Area = a² = 4 ft²

Answer:
Any number that is a whole number not a fraction or decimal

A printer takes 30 minutes to print a banner and a poster. I will take 50 minutes to print a banner and three posters. How long does it take to print a banner?
Answer:
It takes the printer 20 minutes to print a banner
Step-by-step explanation:
Notice that there are two unknowns in this problem: the time to print a poster and the time to print a banner. Let's assign the letter "b" to the time it takes to print a banner, and "p' the time it takes to print a poster.
So we can write the following two equations involving the total amount of time that takes to print in the two cases:
[tex]b+p=30\\b+3p=50[/tex]
We can solve for the unknown "p" by subtracting term by term in the equation set above:
[tex]b+3p=50\\b+p=30\\\\b-b+3p-p=50-30\\2p=20\\p=10[/tex]
So it takes 10 minutes to print each poster, we can find the time it takes to print the banner by using the value we just found in one of the equations:
[tex]b+p=30\\b+10=30\\b=20[/tex]
So, it takes 20 minutes to print a banner.

4a + 6b = 24
6a - 12b = -6
Given the equations what is the value of a+b?
PLZ HELP WILL MARK BRAINLIEST
Answer:
5
Step-by-step explanation:
4a + 6b = 24
6a - 12b = -6
Rewrite the first equation below. Divide both sides of the second equation by 2 and write below the first equation. Then add the equations.
4a + 6b = 24
+ 3a - 6b = -3
----------------------------
7a = 21
Divide both sides by 7.
a = 3
Now substitute 3 for a in the first equation and solve for b.
4a + 6b = 24
4(3) + 6b = 24
12 + 6b = 24
6b = 12
b = 2
a = 3, and b = 2
a + b = 3 + 2 = 5

What is the difference between the highest and lowest points in a data set?
the mean
the median
the mode
the range
Answer:
range
Step-by-step explanation:
difference between the highest and lowest points in a data set = range
The mean is the average of all the points
The median is the middle of all the points
The mode is the point the appears the most often
"Hey diddle diddle the medians the middle you add and divide for the mean the mode is the one that you see the most and the range is the difference between"
Online song that's helped me remember the difference between median, mode, mean and range for years!
The angles of a quadrilateral are in the ratio 2: 3: 5: 8. Find the measure of each angles.
Answer:
see below
Step-by-step explanation:
Let's call the angles 2x, 3x, 5x and 8x and since the sum of angles in a quadrilateral is 360 degrees we can write:
2x + 3x + 5x + 8x = 360
18x = 360
x = 20 which means the angle measures are 40°, 60°, 100° and 160°
Answer:
40°,60°,100° and 160°
Step-by-step explanation:
First add all the ratio's together
2 + 3 + 5 + 8 = 5 + 13 = 18
Now we utilise the fact that angles in quadrilaterals add up to 360. We form an equation like this 18x = 360 to find the value of x and then substitute back into the ratio's
18x = 360
→ Divide both sides by 18 to isolate x
x = 20
Multiply 20 by each of the ratio's to find the angles of this quadrilateral
2 × 20 = 40
3 × 20 = 60
5 × 20 = 100
8 × 20 = 160
So the angles of a quadrilateral with the ratio of 2: 3 : 5 : 8 is 40,60,100 and 160

The total length of a beach is 13.2 kilometers. If lifeguards are stationed every 0.06 kilometers, including one at the end of the beach, how many lifeguards will there be on the beach?
Answer:
220 lifeguards
Step-by-step explanation:
We have to divide the length of the beach by the interval of the stationed lifeguards.
13.2 / 0.06 = 220 lifeguards
There are 220 lifeguards.
A display case has room for 10 statues. Find the number of ways you can line up the statues if you have 5 statues
(Just and Example so it'll kinda explain it.)
Example A
How many ways can 5 students sit in a row?
Solution: If we consider the students sitting in one of five seats, then we have 5 students to choose from for the first seat, four remaining to choose from for the second seat and so on until all the seats are filled.
5–×4–×3–×2–×1–=120 So there are 120 ways to seat the students.
More Guidance
The way we just wrote out 5–×4–×3–×2–×1– can also be expressed as a factorial. A factorial is the product of a number with each number less than itself. We use the notation, 5!, which is read as “five factorial” to represent the expression 5–×4–×3–×2–×1–. It is important to note that 0!=1!=1. Students are often perplexed that both zero and one factorial are equal to one but think back to the context for illustration. If you want to arrange zero items, how many ways can you do it? If you want to arrange one item, how many ways can you do it? There is only one way to “arrange” zero or one item.

Answer:
Step-by-step explanation:
Properties of a bar graph:
1). There should be equal space between the bars or the columns.
2). Width of each bar or columns should be same.
3). All bars should have same base.
4). Height of each bar will show the value of the data.
By these properties,
- Space between London-Paris, Rome-Oslo are not equal.
- Width of Munich bar is different from other bars.
24 is 15% of what number
Answer:
160
Step-by-step explanation:
Is means equals and of means multiply
24 = 15% * N where N is the unknown number
Change to decimal form
24 = .15 N
Divide each side by .15
24/.15 = .15N/.15
160 = N
Answer:
160 because 15% of 160 is 24 meaning 24 is 15% of 160

An architect is making a plan for a new circular playground. If the picture below is the playground, how much fencing needs to go up to keep the kids in the circle? ⬇⬇⬇
Answer:
Length of the fencing required = 201.06 meters
Step-by-step explanation:
Architect is planning a circular playground with diameter = 64 m
We have to calculate the fencing required to cover this playground.
Length of fencing = circumference of the playground
Since circumference of a circle = π × (Diameter)
= 64π
= 201.06 meters
Therefore, length of fencing required to keep the kids in a circle will be 201.06 meters.
Band rues charges $950 to play all night.
DJ phoria charges $350 plus $5 for each ticket sold.
Write a linear equation for the cost of the DJ where y = the total cost and x = the number of tickets sold. The equation for the Band is y = 950.
Graph each equation on the same coordinate plane and find the number of tickets for which the cost of the band and the DJ would be equal. Make sure to name and number the axes of your graph. Also, solve the system of equations analytically, showing all work.
Answer:
120 Tickets
Step-by-step explanation:
Band rues charges $950 to play all night.
Total Cost, y=$950DJ phoria charges $350 plus $5 for each ticket sold.
Total Cost, y=$(350+5x), x = the number of tickets sold.(a)The graph is attached.
From the point of intersection of the two lines, the number of tickets for which the cost of the band and the DJ would be equal is 120 tickets.
(b)
Given the two linear equations
y=950
y=350+5x
Therefore:
950=350+5x
950-350=5x
5x=600
x=120
Therefore, the number of tickets at which the cost of the band and the DJ would be equal is 120, just as obtained above.
