Answer:

The expected value is $0.035

Step-by-step explanation:

expected of outcome for each dice = 1,

each dice has 6 sides ⇒ total number of possible outcome per dice = 6

seven of a kind = $5,000, six of a kind = $500, five of a kind = $50

Probability = (expected outcome ÷ total number of possible outcome) ^ number of dice

Pr = (\frac{E)}{T}^{n}

seven of a kind ⇒ all 7 dice have the same number

Pr (seven of a kind) = (\frac{1}{6})^{7} = 0.00000357

six of a kind ⇒ all 6 dice have the same number

Pr (six of a kind) = (\frac{1}{6})^{6} = 0.0000214

five of a kind ⇒ all 5 dice have the same number

Pr (five of a kind) = (\frac{1}{6})^{5} = 0.000129

EV = ∑P(X_{i}) *

EV = 5,000 * 0.00000357 + 500 * 0.0000214 + 50 * 0.000129

EV = 0.01785 + 0.0107 + 0.00645

EV = $0.035

The chances of winning is less than 1%. This is a very bad risk to take, do not let the carnival operators siphon the money in your wallet

Phil has $20,000, part of which he invests at 8% interest and the rest at 6%. If the total income from the two investments was $
Salsk061 [2.6K]

Answer: 7000

Step-by-step explanation:

Let the amount invested in 8% account be P1 and the amount invested in 6% account be P2

. If the total amount invested is $20,000 then:

P1+P2=20,000. (Eq. 1)

The interest earned in one year from the 8% account is:

I1=0.08P1

and the interest earned in one year from the 6% account is:

I2=0.06P2

If the total interest earned is $1460, then:

I1+I2=1460

0.08P1+0.06P2=1460

(Eq. 2) From Eq. 1 :

P1=20000−P2

Substituting this into Eq. 2:

0.08 (20000−P2) + 0.06P2 = 1460

1600 − 0.08P2 + 0.06P2 = 1460

0.02P2 = 140

P2 = 140 / 0.02

P2 = 7000

Hence, he invested $7000 at the rate of 6%.

You are a running a concession stand selling hot dogs and sodas each hot dog costs .75 cents and each soda costs $1.25. You sold
tatiyna
<span>Each hot dog costs $ 1.50 and each soda costs $ .50. You made a total of $ 78.50. You sold a total of 87 hot dogs and sodas combined. You must report the number of hot dogs and soda's sold. How many hot dogs and soda's were sold? 

Quantity Equation: h + s = 87
Value Equation:: 1.5h+0.5s=78.50

Multiply thru the Quantity Equation by 15
Multiply thru the Value Equation by 10.

15h + 15s = 15*87
15h + 5s = 785</span>Subtract and solve for "s":<span>10s = 520
</span>s = 52 (# of soda's sold)
<span>
Solve for h:
h + s = 87
h + 52 = 87
h = 35 (# of hot dog's sold)</span>
