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?

What is the answer to &gt; solve 4cos (theta/3) -2 = 0, over [0, 4pi)
Vesna [10]

Hello from MrBillDoesMath!

Answer:  

@ =   pi/3 (or 60 degrees) or @ = 7 pi/3 (or 420 degrees)


Discussion:

Let "@' denote the angle "theta". We are asked to find @ in the interval [0, 4 pi)

where

4cos(@) - 2 = 0.                Adding 2 to both sides

4 cos(@) - 2 +2 = 2  =>

4 cos(@) = 2                     Divide both sides by 4

cos(@) = 2/4 = 0.5


This implies that @ =   pi/3 (or 60 degrees) or @ = (pi/3 + 2pi) = 7 pi/3 (or 420 degrees)


Thank you,

MrB

PLS HELP!!! BRAINLIEST
Alina [70]

Answer:

Using the visual, 20 blocks, but you still need to change it to match the problem's scale

Step-by-step explanation:

First just try to find a way out and count the blocks. That's what I did. The part I haven't done is scale it. As the starting and end points of the grid are given, but where they fall is not clear, I don't know what the block to number ratio is. Sorry, maybe ask a teacher, they shouldn't take off any points.

The measures of two angles of a triangle are 61 and 84 degrees. Find the measure of the third angle.
Serhud [2]

Answer:

The measure of the third angle is 35°.

Step-by-step explanation:

The sum of the three angles of a triangle is always 180°.

Let the measure of the third angle be x.

∴ 61° + 84° + x = 180°

           145 + x =180°

                    x = 180 - 145

                    x = 35°

Hope this answer was helpful!!
