Given:
Total of raffle tickets = 30
Number of tickets Jason bought = 10
Number of prizes = 3
To find:
The probability that Jason will win all 3 of the prizes if once a raffle ticket wins a prize it is thrown away.
Solution:
Total of raffle tickets = 30
Number of prizes = 3
So, number of total outcomes is
[tex]n(S)=^{30}C_3[/tex]
Number of tickets Jason bought = 10
So, number of favorable outcomes is
[tex]n(A)=^{10}C_3[/tex]
Now,
[tex]\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]
[tex]\text{Probability}=\dfrac{n(A)}{n(S)}[/tex]
[tex]\text{Probability}=\dfrac{^{10}C_3}{^{30}C_3}[/tex]
[tex]\text{Probability}=\dfrac{\dfrac{10!}{(10-3)!3!}}{\dfrac{30!}{(30-3)!3!}}[/tex]
[tex]\text{Probability}=\dfrac{10\times 9\times 8\times 7!}{7!3!}\times\dfrac{27!3!}{30\times 29\times 28\times 27!}[/tex]
[tex]\text{Probability}=\dfrac{10\times 9\times 8}{30\times 29\times 28}[/tex]
[tex]\text{Probability}=\dfrac{6}{203}[/tex]
Therefore, the correct option is A.
Answer:
The correct answer is A. 6/203

ldentify the hypothesis of the statement
If the slope of a line is positive, then the line is not horizontal.
A) the line is not vertical
B) the line is not horizontal
C) the slope of a line is positve
D) the slope of a line is negative
Answer:
C the slope of a line is positive
Step-by-step explanation:
Hypothesis: The phrase following the "if" part of a conditional statement. So the answer would be c- The slope of a line is positive.
C) the slope of a line is positive
A conditional statement has two parts: hypothesis (if) and conclusion (then).
We have the given statement as:
If the slope of a line is positive, then the line is not horizontal.
Here, "if" part of a conditional statement is the slope of a line is positive
So, the hypothesis of the statement is the slope of a line is positive
Therefore the correct option is (C).

Edwin and Anthony are building a rectangular deck in their backyard. The longer side is 2 ft more than 1/3 of the perimeter. The shorter side is 1/10 of the perimeter. They also know that the longer side is 9 ft longer than the shorter side. What is the perimeter of the deck?
Answer:
30 ft
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Let
Perimeter = x
Length = 1/3x + 2
Width = 1/10x
Length = 9 + 1/10x
Perimeter of the deck = 2(length + width)
x = 2(1/3x + 2 + 1/10x)
x = 2(10x+3x/30 + 2)
x = 2(13/30x + 2)
x = 26/30x + 4
x - 26/30x = 4
30x-26x/30 = 4
4/30x = 4
Divide both sides by 4/30
x = 4 ÷ 4/30
= 4 × 30/4
x = 30 ft
Length = 1/3x + 2
= 1/3(30) + 2
= 30/3 + 2
= 10 + 2
= 12 ft
Width = 1/10x
= 1/10(30)
= 30/10
= 3 ft
Length = 9 + 1/10x
= 9 + 1/10(30)
= 9 + 30/10
= 9 + 3
= 12 ft
The perimeter of the deck = x = 30 ft
Which units are most appropriate for measuring the length of an edge of a postage stamp?
A. Centimeters
B. Feet
C. Kilometers
D. Yards
Answer:
A. Centimeters
Step-by-step explanation:
Option A) is correct.
Solution:
Centimeter is the most appropriate unit for measuring the length of an edge of a postage stamp because feet, kilometer and yards are use for measuring larger objects and edge of an postage stamp is very small in size.

Use the explicit formula to determine the 50th term in the sequence:
2,5,8,11,14,...
Answer:
149
Step-by-step explanation:
There is a common difference between consecutive terms in the sequence.
5 - 2 = 8 - 5 = 11 - 8 = 14 - 11 = 3
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = 3 , thus
a₅₀ = 2 + (49 × 3) = 2 + 147 = 149

After learning how to fly, Wendy reduced her daily commute time by 75% Previously, her commute took m minutes. Which of the following expressions could represent Wendy's commute time, in minutes, after she learned how to fly? Help guys i don't know
Answer:
Given:
(i) Wendy reduced her daily commute time by 75% by learning how to fly.
(ii) Previously, it took her 'm' minutes to commute.
To find:
(i) Wendy's commute time in minutes after she learned how to fly.
Solution:
Given that earlier it took Wendy 'm' minutes to commute.
After learning how to to fly, the commute time reduced by 75%.
So, time taken now = (100-75)% of previous time
= 25% of 'm' minutes
= \frac{25m}{100}
100
25m
= \frac{m}{4}

So, the time taken by Wendy now is \frac{m}{4}

What is the length of AZ?
Use the following information:
A
is between Y
and Z,
YA=22, AZ=16x,
and YZ=166.
The required length of AZ for the line segment YZ is 144.
Given that,
A is between Y and Z,
YA=22, AZ=16x, and YZ=166.
The line is a curve showing the fastestdistance between 2 points.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
YZ = YA + AZ
166 = 22 + 16x
16x = 144
x = 9
Now,
Length of AZ = 16x
= 16 * 9
= 144
Thus, the required length of AZ for the line segment YZ is 144.
