A boardwalk game of chance costs 2 dollars to play. You have a 20% chance of winning 1 dollar, a 25% chance of winning back your entire 2 dollars, and a 35% chance to win 5 dollars. What is the expected value of playing the game if you lose your bet 20% of the time?
Answer:
For a give event with outcomes:
{x₁, x₂, ..., xₙ}
Each with probabilities:
{p₁, p₂, ..., pₙ}
The expected value is:
Ev = x₁*p₁ + ... + xₙ*pₙ
Here we have the outcomes and probabilities:
win $1, with a probability 20%/100% = 0.2
win $2, with a probability 25%/100% = 0.25
win $5, with a probability of 35%/100% = 0.35
do not win, with a probability of 20%/100% = 0.2
Then the expected value of the game is:
Ev = $1*0.2 + $2*0.25 + $5*0.35 + $0*0.2 = $2.45
And if we know that the game costs $2, then the expected value is:
Ev = $2.45 - $2 = $0.45
The expected value is $0.45

Determine the equations of the vertical and horizontal asymptotes, if any, for
Given:
The function is:
[tex]f(x)=\dfrac{2x}{x+4}[/tex]
To find:
The vertical and horizontal asymptotes of the given function.
Solution:
We have,
[tex]f(x)=\dfrac{2x}{x+4}[/tex]
For vertical asymptotes, equate the denominator and 0.
[tex]x+4=0[/tex]
[tex]x+4-4=0-4[/tex]
[tex]x=-4[/tex]
So, the vertical asymptote of the given function is [tex]x=-4[/tex].
The degree of the numerator is 1 and the degree of the denominator is also 1.
Since the degrees of numerator and denominator are equal, therefore the horizontal asymptote is:
[tex]y=\dfrac{a}{b}[/tex]
Where, a is the leading coefficient of numerator and b is the leading coefficient of denominator.
Leading coefficient of numerator is 2 and the leading coefficient of denominator is 1, so the horizontal asymptote is:
[tex]y=\dfrac{2}{1}[/tex]
[tex]y=2[/tex]
Therefore, the correct option is C.

Sarah had 25 candies. Sarah gave 25 of the candies to her sister. Of the amount left, she gave 2/3 to her friend. How many candies does Sarah have left for herself?
Answer:
She has 5 candles left.
Step-by-step explanation:
Total of candy Sarah has = 25candies
If Sarah gave 2/5 of the candies to her sister, the total amount she gave her sister will be 2/5 of 25
2/5 of 25 = 10
The remaining candy left will be 25-10 which is 15.
If she gave 2/3 of the amount left to her friend, the amount she gave her friend will be 2/3×15 = 10candies.

A data set is displayed using a dot plot. The range of the data is between 50 and 90, and the distribution is skewed left. Where is there most likely a peak in the data?

middle of the graph
cannot be determined without more information
please help
Hello,
Your answer would be right side of the graph
Please mark as brainiest
The peak in the data would likely be the right side of the graph.
The distribution of a data set when displayed on a dot plot is said to be skewed left (left skewed) when most of the data appear on the right side of the graph. This means, the highest scores are on the right while the lowest values of the variable are on the left side of the graph (in order words, tapers towards the left of the graph). See the image labelled A in the attachment below.
Also, for a data set distribution that is skewed right (right skewed), most of the data appear on the left side of the graph. It will have a tail tapering to the right. See the image labelled A in the attachment below.
For a data distribution that is skewed to the left, the peak in the data would most likely be at the right side of the graph.For a data distribution that is skewed to the right, the peak in the data would most likely be at the left side of the graph.Therefore, for data set that ranges between 50 and 90, and the distribution is skewed left, the peak in the data would be to the right of the graph.

Two adjacent angles of a parallelogram have equal measure. Find the
measure of each of the angles of the parallelogram.
Step-by-step explanation:
Let ABCD be the parallelogram with ∠A = ∠B.
We know: Sum of adjacent angles = 180°
∠A + ∠B = 180º
2∠A = 180º (∠A = ∠B)
∠A = 90º
∠B = ∠A = 90º
∠C = ∠A = 90º (Opposite angles)
∠D = ∠B = 90º (Opposite angles)
Thus, each angle of the parallelogram measures 90º
Answer:
All 4 angles are 90 degrees.
Step-by-step explanation:
The measure of 2 adjacent angles in a parallelogram add up to 180 degrees.
If they have equal measure then they are both 90 degrees.
As it is a parallelogram:-
the measure of each angle is 90 degrees.

SA= Surface area, and surface area is A=2(w×l+h×l+h×w) and volume is V=w×h×l
W=width
H=height
L=length
Answer:
1. SA=58
2. SA=48
3. SA=78
4. V=168
5. V=960
6 V=420
Step-by-step explanation:
on 1-3 you are looking for the surface area and in order to look for the surface area of a rectangle prism it is 2(height)x2(lenght)x2(width). so you just plug in the number height is how tall the shape is, length is how long the shape is and width is hpw far the shape goes back. then you multiply the H, L, W by 2 and the you add all of the numbers and boom you get your answer.
Now for the Volume you just multiply the heigh x length x width and boom you answer
height increase (m)
Temperature drop (°C)=
200
If the temperature at a height of 500 m is 23°C, what will it be when you climb to 1300 m
How far would you need to climb to experience a temperature drop of 5°C?
Complete question is;
In mountaineering, in general, the higher you go, the colder it gets. This formula shows how the heights and temperatures are related.
Temperature drop (°C) = height increase(m)/200
A) If the temperature at a height of 500 m is 23°C, what will it be when you climb to 1300 m
B) How far would you need to climb to experience a temperature drop of 5°C
Answer:
A) 19°C
B) 1500 m
Step-by-step explanation:
A) We are told that the temperature is at a height of 500 m is 23°C, now we want to find the temperature when height increases to 1300 m.
Thus, it means;
Height increase = 1300 - 500 = 800 m
Thus, from the formula;
Temperature drop (°C) = height increase(m)/200, we have;
Temperature drop (°C) = 800/200 = 4°C
Now,since Initial temperature was 23°C, thus temperature at this increased height ; 23°C - 4°C = 19°C
B) for a temperature drop of 5°C, we have;
5°C = height increase(m)/200
Height increase = 200 × 5
Height increase = 1000 m
Thus, you will need to climb; 500 + 1000 = 1500 m
