The expected value for a person who buys a ticket is $0.35.
We have,
Number of tickets sold = 100
Price of each ticket = $1
Prize value (1st prize) = $25
Prize value (2nd prize) = $10
Let's calculate the expected value step by step:
Calculate the probability of winning each prize:
Since there is only one 1st prize and one 2nd prize, the probability of winning each prize is:
Probability of winning the 1st prize = 1/100
Probability of winning the 2nd prize = 1/100
Calculate the expected value:
Expected value = (Probability of winning 1st prize x Value of 1st prize) + (Probability of winning 2nd prize x Value of 2nd prize)
= (1/100 x $25) + (1/100 x $10)
= $0.25 + $0.10
= $0.35
Therefore, the expected value for a person who buys a ticket is $0.35.

What is a triangle?A polygon with three sides and angles is called a triangle.
Given is a figure, with the rulers attached to each side, we need to see what are the measurements of the sides of the triangle,
The first side is showing a measure of 13
The second side is showing a measure of 12
And, the third one is showing a measure of 5
This is a right triangle because the measurements are Pythagorean triplets.
Hence, the three side lengths best describe the triangle in the diagram are A. 5 cm, 12 cm, and 13 cm

Jason wanted to place all 540 marbles in the 3 newly bought boxes. If he wants to
divide it in a ratio of 1:2:3, how many marbles would be in each box?
I really need your help please!!, thank you.
Answer:
The first box will have 90 marbles, the second 180 and the third 270.
Step-by-step explanation:
Division in a ratio of 1:2:3
1 + 2 + 3 = 6
So
The first box will have 1/6 of the marbles.
The second box will have 2/6 = 1/3 of the marbles
The third box will have 3/6 = 1/2 of the marbles.
First box:
One sixth, so:
(1/6)*540 = 540/6 = 90
Second box:
One third, so:
(1/3)*540 = 540/3 = 180
Third box:
One half, so:
(1/2)*540 = 540/2 = 270
The first box will have 90 marbles, the second 180 and the third 270.

Create a word problem that can be represented by the expression in number 4. –6 ÷ 1 1/3
Answer:
I suppose that we want to use the expression in number 4.
The expression we need to use is:
6/(1 + 1/3)
This is:
"the quotient between the number 6 and the number 1 and 1/3"
We could write a problem like:
"We have 1 and 1/3 pounds of apples, and we have 6 grams of caramel that we want to divide evenly between all the apples. How much caramel we will have in each pound of apples?"
Then we need to divide the total amount of caramel by the total amount of apples, this is:
(6gr)/(1 + 1/3 lb) = (6/(3/3 + 1/3 )) gr/lb = (6/ 4/3) gr/lb = 6*(3/4) gr/lb
= 18/4 gr/lb = (16 + 2)/4 gt/lb = 16/4 gr/lb + 2/4gr/lb = 4 gr/lb + 1/2 gr/lb
= (4 and 1/2) gr/lb

Identify the values of a,b, and c that could be used with the quadratic formula to solve the equation. Enter a as a positive integer value.
x^(2)=6(x-8)
A=
B=
C=
THANK YOU SO MUCH
Answer:
a=1
b= -6
c=48
Step-by-step explanation:
x^2=6(x-8)
x^2=6x-48
x^2-6x+48
a,b are the coefficients of x^2 and x
c is the constant value present
Therefore it is basically written as ax^2+bx+c
and comparing with the answer x^2-6x+48,
a=1, b= -6, c=48
Solve the quadratic equation numerically (using tables of x- and y- values).
(x +2) (x + 3) = 12
a.
x = -1 or x = 3
c.
x = -6 or x = 1
b.
x = 2 or x = -3
d.
x =1 or x = -1
