In a game, you toss a fair coin and a fair six-sided die. If you toss a heads on the coin and roll either a 3 or a 6 on the die,

pochemuha

Using probabilities, it is found that the expected profit of one round of this game is of $0.

A probability is the number of desired outcomes divided by the number of total outcomes.

One of the two sides of the coin are heads.
2 of the 6 sides of the dice are 3 or 6.

Hence, since the coin and the dice are independent, the probability of winning is:

$p = \frac{1}{2} \times \frac{2}{6} = \frac{1}{6}$

The expected value is the sum of each outcome multiplied by its respective probability.

In this problem:

$\frac{1}{6}$ probability of earning $30.
$\frac{5}{6}$ probability of losing $6.

Then:

$E(X) = 30\frac{1}{6} - 6\frac{5}{6} = 5 - 5 = 0$

The expected profit of one round of this game is of $0.

sukhopar [10]

Answer:

0.42 ft

0.92 ft

Step-by-step explanation:

Width of mural on painting = 5 inches

Height of mural on painting = 11 inches

12 inches of the painting represents 1 foot of the mural

1 inch of the painting represenets $\dfrac{1}{12}$ foot of the mural.

$5\ \text{inches}=5\times \dfrac{1}{12}=0.42\ \text{ft}$

$11\ \text{inches}=11\times\dfrac{1}{12}=0.92\ \text{ft}$

The width of the mural is 0.42 ft and height of the mural is 0.92 ft.

Last summer Myrtle, worked 45 hours and earned $443.70. She wanted to make at least $550 this summer. Using an inequality, find

Ierofanga [76]

Answer:

11 hours

Step-by-step explanation:

Using an inequality, find how many additional hours must she work in order to reach this goal?

From the above question, the term at least means less than or equal to and it is represented by the inequality = ≤

Hence,

Let the number of additional hours = h

Last summer Myrtle, worked 45 hours and earned $443.70.

The amount she earned per hour = $443.70/45

= $9.86

Our inequality equation is written as;

She wanted to make at least $550 this summer.

$9.86 × h ≤ $550

= 9.86h ≤ 550

h = 550/9.86

h = 55.780933063 hours

Approximately the additional hours she has to work =

55.780933063 - 45 hours

= 10 .780933063 hours

Approximately = 11 hours
