An artist wants to create a poster that includes a picture of the winners of
the 1500-meter race at the Olympics from 1896 to 2000. If a man has won
the race more than once, his picture will only appear once. The pictures will
be laid out in columns and rows, and they will be placed randomly. The top
row will contain four pictures. What is the probability that the top row will
include Josy Barthel of Luxembourg, Teddy Flack of Australia, Noah Negeny
of Kenya, and Jim Lightbody of the United States?
Using the combination formula, it is found that there is a [tex]p = \frac{1}{1540}[/tex] probability of the desired top row.
What is the combination formula?[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Looking at the table, there are 22 different winners, and 3 will be selected for the total row, hence the total number of options is given by:
[tex]T = C_{22,3} = \frac{22!}{3!19!} = 1540[/tex].
There is only one desired combination, as the order does not matter, hence the probability is given by:
[tex]p = \frac{1}{1540}[/tex]

Find the scale factor of the dilation.
The scale factor is
Answer:
2
Step-by-step explanation:
its the wrong anwser
Answer:
0.5
Step-by-step explanation:
Scale factor is the final size (of image D'E'F'G') compared to that of the original (DEFG).
So the dilation factor is 3/6 = 0.5 (less than one means diminution in size.

What is the value of p?
Step-by-step explanation:
70-26= 44°
Might be wrong but hope it helped!
Answer:
Hello! answer: p = 44
Step-by-step explanation:
These are vertical angles!
Meaning that each will equal the same
Since we are given its vertical angle we know that it will have to add up to 70 on the other side as well so...
70 - 26 = 44 therefore p = 44 hope that helps!

Find the equation of the exponential function represented by the table below:
Answer:
x=2
Step-by-step explanation:
In the table the ratio of x to y in the first one is 0:2 and ongoing.
Answer:
[tex]f\left(x\right)=\ 2\left(2\right)^{x}[/tex]
Step-by-step explanation:
Step 1: Make a equation, f(x)= ab^x.
A is the y value, whenever the x value is zero. So, a is 2.
Lets put that in our equation:
f(x)= 2b^x.
B is the common ratio on the y values. When you follow the pattern, 2, 4, 8, 16, you realize that the common ratio is 2. 2*2 is 4, 4*2, is 8, 8*2 is 16, and so on. So the common ratio is 2.
Lets go ahead and add that to our equation:
f(x)= 2(2)^x.
There is no more steps in this process, so that is actually your final answer:
[tex]f\left(x\right)=\ 2\left(2\right)^{x}[/tex]
Hope this helps :)

Read this main idea: The sun is the center of our solar system. Choose three details that go with the main idea.
The sun's gravity holds the planets in place. It provides them with heat and light.
The largest stars, called supergiants, are 1,500 times bigger than our sun.
It takes Earth 365 days to orbit the sun. Jupiter takes 12 years!
Our sun is not the largest or hottest star. It is a medium sized yellow star.
Radio telescopes use radio waves to show stars in great detail.
Astronomers long ago and today use star charts to map star locations.
All of the planets in our solar system revolve around one star-our sun.
Stars can be blue, white, yellow, or red. Blue stars are the hottest.
A reflector telescope bounces star light through mirrors.
Answer:
1. All planets in our solar system revolve around one star- our sun
2. The sun's gravity holds the planets in place. It provides them with heat and light.
3. It takes Earth 365 days to orbit the sun. Jupiter takes 12 years!

Mary purchased 12 candy bars for $14.04
Happy Pride Month!
Answer:
12c=$14.04
Step-by-step explanation:
First lets find out how much each candy bar cost
14.04/12=1.17
so
$1.17*12 = $14.04
so d is the correct answer becuase you would need to multiply the cost of each candy which would be $1.17 by how many candy bars you have which is 12 then get the answer of the total cost that would be $14.04
Answer:
12c = 14.04

Answer:
1.6
Step-by-step explanation:
The Mean Absolute Deviation (MAD) is the distance each number is away from the mean divided by the amount of numbers.
15 is 4 away from 19, for example
So:
19 - 15 = 4
25 - 19 = 6
19 - 13 = 6
19 - 15 = 4
19 - 18 = 1
20 - 19 = 1
22 - 19 = 3
24 - 19 = 5
4 + 6 + 6 + 4 + 1 + 1 + 3 + 5 = 30
30/19 = 1.5789, rounded to 1.6
Answer:
Use 19, and subtract each number. For example, if it is 15, you do 19 - 15, but if it is over 19, like 24, do 24 - 19. Do this to all the numbers and add them up, thats your mad.
