This deck of cards has 4 aces out of a total of 52 cards.
Then the probability can be explained as the number of favorable outcome/number of what is the possible outcome.
P(win) = number of favorable outcome/number of possible outcome
= 4/52
= 1/13
P(loss) = number of favorable outcome/number of possible outcome
= 48/52
= 12/13
Then we have
$10x1/13 + (-1)x12/13
= 10/13-12/13
= -2/13 dollars
= -$0.15
Using the principle of discrete probability, the expected value, which a measure of the mean amount after many plays is - 2/13
Calculating the required probabilities :
P(winning) = P(drawing an Ace) = 4/52 = 1/13
Hence, P(losing) = 1 - 1/13 = 12/13
X :____ 10 _____ - 1
P(X) : _ 1/13_____ 12/13
The expected value :
E(X) = 10 × (1/13) + - 1(12/13)
E(X) = 10/13 - 12/13
E(X) = - 2/13
Hence, the measure of the mean amount is -2/13.

A rectangular box has length 20cm, width 6cm and height 4cm. find how many cubes of size 2cm that will fit into the box.
Answer:
[tex]\boxed{\pink{\sf The \ number \ of \ cubes \ that \ can \ be \ fitted \ is 60 .}}[/tex]
Step-by-step explanation:
Given dimensions of the box = 20cm × 6cm × 4cm .
Dimension of the cube = 2cm × 2cm × 2cm .
Therefore the number of cubes that can be fitted into the box will be equal to the Volume of box divided by the Volume of the cube. So ,
[tex]\boxed{\red{\bf \implies No. \ of \ cubes \ = \dfrac{Volume \ of \ box}{Volume \ of \ cube }}}[/tex]
[tex]\bf \implies n_{cubes} = \dfrac{20cm \times 6cm \times 4cm .}{2cm \times 2cm \times 2cm } \\\\\bf\implies n_{cubes} = 10 \ times 3cm \times 2cm \\\\\implies \boxed{\bf n_{cubes}= 60 }[/tex]
Hence the number of cubes that can be fitted in the box is 60 .Please HELP (due after 20 mins)

A superintendent of a school district wants to understand the link between attendance and grade point average, or GPA. The GPA is out of 4.0 points, with 4.0 being the highest possible. The percent attendance and GPA of 10randomly sampled students from the superintendent's district were collected. This sample data is reproduced in the table below. Calculate the correlation coefficient r using a TI-83, TI-83 plus, or TI-84 graphing calculator (round your answer to two decimal places).
"GPA" 3.5 2.38 1.16 3.83 3.28 3.69 3.46 3.87 3.69 3.75
Attendance 91% 74% 80% 97% 59% 78% 90% 98% 94% 87%
r=_______.
Answer:
0.4136
Step-by-step explanation:
Given the data:
"GPA":
3.5
2.38
1.16
3.83
3.28
3.69
3.46
3.87
3.69
3.75
Attendance

0.74
0.80
0.97
0.59
0.78
0.90
0.98
0.94
0.87
The value of R (correlation Coefficient) obtained for the two variables GPA and ATTENDANCE is 0.4136. This shows that a fairly weak relationship between the GPA obtained and the attendance of students. Hence, even though a positive relationship exist between the two variables, that is, an increase in one variable yields a corresponding increase in the other and vice versa. The correlation Coefficient value for both values is just fairly strong.

Becca made 960 cookies to sell. She wants to package the cookies in the the boxes of 16 . Her goal is to make $630 from selling her cookies . If each box of cookies is priced the same , how much should Becca charge for each box ?
Step-by-step explanation:
Total cookies = 960
Each box has 16 cookies
Her goal is $630
First, you want to find out how many boxes she made
960÷ 16 = 60
She made 60 boxes
Now you want to find the price for each box
630 ÷ 60 = 10.5
She should charge $10.50 for each box

The cost of a ticket to a Circus & Fan Fair show is $69 for adults and $26 for children. On a
certain day, 5 times as many children attend the show than adults, and the total revenue is
$94,908. About how many adults bought tickets?
Let the number of adults equal x, and the number of children equal 5x.
26(5x) + 69x = 94908
194x = 94908
x = approx. 489
About 489 adults bought tickets.
A total of 489 adults take tickets to the circus & Fan Fair show.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say the number of tickets that adults bought is a and the number of tickets that children bought is c.
Then,
26(5a) + 69c = 94908
194a = 94908
a = 489.21 but we need to take the whole number and practical number so it will be 489.
Hence "A total of 489 adults take tickets to the circus & Fan Fair show".

amy ate 27.5 cookies in 5.5 minutes. How many cookies did she eat per minute?
Answer:
5 cookies per minute.
Step-by-step explanation:
To do this, we divide 27.5 by 5.5 to get the unit rate, in other words, the amount of cookies eaten per minute. This gets us 5. That means Amy ate 5 cookies per minute.
Answer:
Amy ate 5 cookies per minute
Step-by-step explanation:
Do get the unit rate - the number of cookies per minute - you can divide 27.5/5.5. You then get 5. This means that Amy ate 5 cookies per minute.

The inequality which is graphed on the coordinate plane is y > -x + 2, the correct option is B.
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
An inequality is a mathematical statement that compares two values or expressions using a relational operator, such as less than (<), greater than (>), less than or equal to (≤), greater than or equal to (≥), or not equal to (≠). Inequalities are used to describe relationships between quantities or to express constraints or conditions.
We are given that;
The graph of inequality
Now,
the graph shows a dashed line with a slope of -1 and a y-intercept of 2, which is the equation y = -x + 2. The dashed line means that the points on the line are not included in the solution set of the inequality. The shaded region above the line means that the points in that region satisfy the inequality.
Therefore, by the inequality the answer will be y > -x + 2.
