Answer:

Expected value for 4 tickets = $ -7.6

Step-by-step explanation:

Given - A lottery offers one $900 prize, one $600 Prize, three $400 prizes, and four $100 prizes. One thousand tickets are sold at $5 each.

To find - Find the expectation if a person buys four tickets. Assume that the player's ticket is replaced after each draw and that the same ticket can win more than one prize. Round to two decimal places for currency problems.

Proof -

Given that,

A lottery offers

one $ 900 prize

one $ 600 prize

three $ 400 prizes

Four $ 100 prizes

And

One thousand tickets are sold at $ 5 each

Now,

If the person bought 1000 tickets then the prize he gets is

= 900 + 600 + 3×400 + 4×100

= 900 + 600 + 1200 + 400

= $3100

And

The cost of 1000 tickets = 5×1000 = $ 5000

Now,

Price 1 ticket = [tex]\frac{3100}{1000}[/tex] = $ 3.1

⇒Expectation of 1 ticket = $ 3.1 - 5 = $ -1.9      (Here $5 is price of 1 ticket)

⇒Expected value for 4 tickets = $ 4× -1.9 = $ -7.6

⇒Expected value for 4 tickets = $ -7.6

[tex]\large\boxed{A = 12.5 \text{ units}^{2}}[/tex]

Find the area of the shape using the formula for the area of a trapezoid:

A = 1/2(b1 + b2) · h

Where:

b1 = base 1

b2 = base 2

h = height

A = area

Plug in the given bases and height:

A = 1/2(7.5 + 2.5) · 2.5

Simplify:

A = 1/2(10) · 2.5

A = 5 · 2.5

A = 12.5 units²

V= 6,732 gal

Answer:

0.024

Step-by-step explanation:

First, multiply 6 by 4 to get 24. Since there is a hundredth and a tenth, you have to move the digit 3 units right to get 0.024.

Area of cube formula - A=6a2

Area of rectangular prism - A=2(wl+hl+hw)

Answer:

1. Nets

2. Surface Area

3.area

4. add

5. A= 1/2 bh

Step-by-step explanation:

Side A- 8x5 = 40 sq.m

Side B - 3x8 = 24 sq.m

side c - 5x8 = 49 sq.m

side d - 1/2 ( 3x 2) = 3

side E- 1/2 (3x2) = 3

Area of rectangular prism - 2 (wl + wh + lh)

surface area of cube = 6a^2 ( a is edge)

Answer:

x=15

Step-by-step explanation:

Hello there!

The shown angles are vertical angles

if you didn't know vertical angles are congruent

That being said we can create equation

5x + 40 = 115

now we solve for x

step 1 subtract 40 from each side

40 - 40 cancels out

115 - 45 = 75

now we have 75 = 5x

step 2 divide each side by 5

5x/5=x

75/5=15

we're left with x = 15

Answer:

9

Step-by-step explanation:

-3^3 +5*(3)^2 +3*-3

-27+5*9+(-9)

-27+45-9

=9

Answer:

Step-by-step explanation:

Wherever you see an x, put in -3

y=(-3)^3 + 5(-3)^2 + 3(-3)

y = - 27 + 5 * 9 +  -9

y = -27 + 45 - 9

y = 9

The missing probability will be P(A) = 3/25. The correct option is C.

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 indicates that an event is impossible, and 1 indicates that an event is certain. Probability is used in mathematics, statistics, and many other fields to quantify uncertain or random events.

To find the missing probability P(A), we can use the formula for the probability of the intersection of two events:

P(A and B) = P(A) * P(B|A)

Where P(B|A) is the conditional probability of B given A.

Rearranging this formula, we get:

P(A) = P(A and B) / P(B|A)

To find P(B|A), we can use the formula for conditional probability:

P(B|A) = P(A and B) / P(A)

Substituting this into the first formula, we get:

P(A) = P(A and B) / (P(A and B) / P(A))

Simplifying, we get:

P(A) = P(A and B) / P(B)

Substituting the given values, we get:

P(A) = (6/25) / (2/5)

Simplifying, we get:

P(A) = (6/25) x (5/2)

P(A) = 3/25

Therefore, the missing probability is P(A) = 3/25.
