Your friend Phil, asks you what you think about a new scratch-off lottery game. It costs $10 to play this game, There are two ou

tcomes for the game (win, lose) and the probability that a player wins a game is 60%. A win results in $15, for a net win of $5 ($15 minus the $10 paid to play). The probability distribution for xx (the amount of money a player wins or loses) in a single game is as follows:_______.
1-Net Money Won or Lost Px) - Probability Win + $ $ 5 0.60 Lose - $ 10 0.40 Using the information in the table, complete the following 1. Interpret the table. There is a 60% • chance of winning $5 and a 40% • chance of losing $10 • 2. What is the expected value of x? E(X) = -1 3. What is the standard deviation? o = 7.35 (Round to then nearest hundredth). This question is based on the information from the previous question. 1. If Phil plays the game 1 time, how likely is he to win money? There is a _ % chance that Phil will win if he plays 1 time. 2. Phil thinks if he plays the game many, many times, he is likely to make money because the percent of winning sounds good to him. Is he right? Why or why not? A B I I % $ 3 = UX2 x S # - © © E = C A # * <> X 1. 1 Point: If Phil plays the game 1 time, how likely is he to win money? There is a % chance that Phil will win if he plays 1 time. 2.2 Points: Phil thinks if he plays the game many, many times, he is likely to make money money because the percent of winning sounds good to him. Is he right?

Unit Test / 16 of 25
Rzqust [24]

Answer:

30

Step-by-step explanation:

For the minimum free throws, he must put every throw to the basket.

So, let n be the number of throws for Tuesday, in which all the throws are successful.

So, over both the days, total free throws he makes= 15+n.

Total numbers of throws that went in the basket= 6+n.

As he wants at least 80% of his balls to go in the basket.

So, 6+n is greater than or equal to 809% of 15+n, i.e

6+n\geq \frac{80}{100}\times (15+n)

\Rightarrow 30+5n\geq 60+4n

\Rightarrow n\geq 30.

Hence, the minimum number of free throws required on Tuesday to reach his goal is 30.

When point A( 3, 1) is translated 2 units to the right and 6 units up the coordinates of point A'
9966 [12]

Answer:

A' = (5,7)

Step-by-step explanation:

So, we start with the original point A at (3,1), that means x = 3 and y = 1.

We move it 2 units to the right... so we're moving along the X-axis... and we're moving to the right.. so we're increasing the value of x.  That means starting with x = 3, we go 2 more units... we then get to x = 5.

In the same way, we move 6 units up... so we move along the Y-axis.  We go up, so we also increase the value of y.  Starting with y = 1, we move up by 6 units... so we are now at y = 7.

A' point is then at (5,7).

Determine the length of the hypotenuse of a right triangle if the legs have lengths 12 inches and 16 inches?
tiny-mole [99]

Answer:

c = 20 inches

Step-by-step explanation:

To find the sides of a right triangle, you use the Pythagorean Theorem.

a² + b² = c²

You know a and b, and you need to find c, the hypotenuse.

Plug in a and b.

(12)² + (16)² = c²

Simplify by solving the exponents.

144 + 256 = c²

Combine the constants.

400 = c²

Take the square root of both sides.

√400 = √c²

Solve the √

±20 = c

The length cannot be negative, so you can eliminate that as an option.

So, c = 20
