Pooja and Amit are playing a card game with a standard 52 card deck. Pooja will draw a card. If the card she draws is a face card (a jack, queen, or king), she will win $6. If Pooja draws an ace, she will win $4. If any other card is drawn, she will lose $2. The image below shows a standard deck of playing cards.
What is Pooja's expected value of playing this game?
The probability helps us to know the chances of an event occurring. Pooja's expected value of playing this game is 0.3077.
What is Probability?The probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
There are 12 face cards, therefore, the probability of the getting a face card can be written as,
[tex]\text{Probability of face card }= \dfrac{12}{52} = 0.2308[/tex]
Also, the winning prize for drawing a face card is $6. Therefore, the expected value will be,
[tex]\text{Expected Value(Face)} = \$6 \times 0.2308= $1.3846[/tex]
There are 4 ace cards, therefore, the probability of the getting an ace card can be written as,
[tex]\text{Probability of ace card }= \dfrac{4}{52} = \dfrac{1}{13} = 0.077[/tex]
Also, the winning prize for drawing an ace card is $4. Therefore, the expected value will be,
[tex]\text{Expected Value(Ace)} = \$4 \times 0.077 = $0.3077[/tex]
There are 36 normal cards, therefore, the probability of the getting a normal card can be written as,
[tex]\text{Probability of normal card }= \dfrac{36}{52} = 0.6923[/tex]
Also, the losing prize for drawing a normal card is -$2. Therefore, the expected value will be,
[tex]\text{Expected Value(Normal)} = (-\$2) \times 0.6923 = -$1.3846[/tex]
Thus, Pooja's expected value of playing this game can be written as,
[tex]\rm Expected\ Value = 1.3846 + 0.3077-1.3846 = 0.3077[/tex]
Hence, Pooja's expected value of playing this game is 0.3077.

how many groups of 5/6 are in 1
Answer:
1 1/5
Step-by-step explanation:
2x- 1 = 7
A= 2
B = 3
C=4
D=5
Answer:
4
Step-by-step explanation:
All you need to do is plug in each value for x & then solve the equation to see if it equals 7. When a number, like 2, is next to an x you multiply the two of them. So when you substitute a number for x, you multiply it by the 2.
2(3)-1= 5
2(4)-1= 7
2(5)-1=9

a bug population doubles every 5 days. If you start with 6 bugs, how many bugs will there be in 35 days
Answer:
768 bugs
Step-by-step explanation:
You can rewrite this problem as a function as time where the bug population is f(x), and x is the number of days since the start.
f(x)=6*2^(x/5)
Here, the 6 represents the number of bugs that you start with, the two shows that they double every day, and the /5 shows that they double every 5 days.
By plugging in 35, you get 6*2^7, which is 768.

Dennis is driving down the East Coast of the United States. He starts in Boston, MA, and drives through Hartford, CT, which is approximately 101 miles away from Boston. He continues on from Hartford to Baltimore, MA.
Write an equation for the length of Dennis' trip in miles in terms of the hours it takes him to drive from Hartford to Baltimore and the speed he drives in miles per hour while driving from Hartford to Baltimore. Describe all variables used and what each coefficient means
The equation representing the length of Dennis' trip in miles in terms of the time it takes to travel and the speed of Dennis is: d = s×t miles
How are time taken for travel, distance traveled, and the average speed are related?We have this below shown relation between them
[tex]\text{Average speed} = \dfrac{\text{Distance traveled}}{\text{Total time taken to travel that distance}}\\\\or\\\\\text{Total time taken to travel that distance}= \dfrac{\text{Distance traveled}}{\text{Average speed} }[/tex]
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
Let we take:
Distance from Hartford to Baltimore = d milesTime it takes for Dennis to drive from Hartford to Baltimore = t hoursAverage speed of Dennis in the considered drive = s miles per hour.Then, we get:
[tex]s = \dfrac{d}{t}\\\\d = s \times t \: \rm miles[/tex]
Thus, the equation representing the length of Dennis' trip in miles in terms of the time it takes to travel and the speed of Dennis is: d = s×t miles

Cody is painting the front door of his house. The dimensions of the door are 80 inches by 36 inches by 2 inches. If he paints all of the surfaces how much area will he paint? Explain.
Answer:
To find out how much area he will paint, you will find the area of all 6 faces.
Each face is in the shape of a rectangle, so use A = lw as your formula.
Front/Back: 80 x 36 = 2880 square inches
2880 square inches x 2 = 5760 square inches
Right/Left Sides: 80 x 2 = 160 square inches
160 square inches x 2 = 320 square inches
Top/Bottom: 36 x 2 = 72 square inches
72 square inches x 2 = 144 square inches
5760 + 320 + 144 = 6224 square inches.
Cody will paint 6224 square inches.

Find the equation of the line shown
Answer:
[tex]y=-\frac{1}{4}x+2[/tex]
Step-by-step explanation:
We will use the point slope formula: [tex]y=mx+b[/tex]
We will start by finding the slope([tex]m[/tex]).
The formula for slope is
[tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
So if we just choose 2 random points on the line:
I choose (0,2) and (4,1), we get:
[tex]\frac{1-2}{4-0} = \frac{-1}{4}[/tex]
That's our slope.
Next we need to find the y-intercept([tex]b[/tex]). We can find that by looking at the graph. It is where x=0. So in this case y=2 when x=0.
So in point-slope form the equation is:
[tex]y=-\frac{1}{4}x+2[/tex]
Write the slope intercept form of the equation. Through (-3, -2) perpendicular to y=-3x
Answer:
y=1/3x-11
Step-by-step explanation:
Perpendicular to y=-3x
Get the negative reciprocal to find your new slope
1/3x is our new slope
y=mx+b
Plug coordinates in:
-2=-3(-3)+b
-2=9+b
b=-11
In his second year, a football player scored two less than twice the number of touchdowns he scored in his rookie year. If t represents the number of touchdowns he scored in his rookie year, write an expression for the number of touchdowns he scored in his second year in factored form.
Using a system of equations, the expression or the number of touchdowns he scored in his second year is: 2(t - 1)
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In his first year, he scored t touchdowns. In the second, the amount was two less than twice the number of touchdowns he scored in his rookie year, hence the expression is:
2t - 2 = 2(t - 1)
