Answer:
two situations in which a person or business might use probability to make a decision
1. Weather Forecasting
2. Sales Forecasting
explanation
Weather Forecasting : the individual might question themselves about what the weather is gonna look like the day . is it gonna rain ? should I bring an umbrella ? should i take the car to work just incase it starts raining , or should I walk on foot and enjoy the hot sun?
Many retailers use probability to forecast the possibility of selling a specific amount of products on a given day, week, or month. This allows companies to forecast how much stock they will require in the future. A company, for example, may use a forecast model that claims it has a 90% chance of selling at least 100 items on a given day. To avoid running out of items to sell, keep at least 100 (preferably more) on hand at all times.

earned an A for both the final exam and the entire course. What is the probability that a randomly
selected student in this class did not earn an A on the final exam and did not earn an A for the entire course
The probability a student did not earn an A on the final exam or entire course is 75%.
What is probability?This refers to the likeliness for an event to occur, which can be expressed using percentages.
How to calculate the probability?The general formula is the number of specific outcomes/ total of outcomes.
What is the probability in this case?The number of students who did not earn an A on the final exam or entire course: 21 (only 7 students earned an A on both)

A plane drops 300 feet, rises 240 feet, drops 180 feet, and rises 130 feet. What is the height of the plane now relative to its initial height?
Answer:
it is IH - 110 ft
Step-by-step explanation:
The plane height is down 110 feet from its initial height.
What is subtraction?Subtraction is mathematic operation. Which is used to remove terms or objects in expression.
Let x be the initial height of the plane.
Then according to question;
if drop down means height in negative term and rise up means height in the positive term.
Then,
the height is
= x -300-180+240+130
= x-110
Therefore, down 110 feet is the height of the plane now relative to its initial height.

First, combine like terms:
4x -58 +x =2 can be rewritten as 5x - 58 =2
Next, isolate the x on one side of the equation by adding 58 to both sides:
5x = 60
Now, isolate x again by dividing by 5 on both sides of the equation:

By standard notation, if May wins money, then we represent this with a positive number.
While if she pays or has a debt, we represent the change with a negative number (because now she has less money than before).
A) She receives $25, so the change is:
C = $25
B) She earns $14, so the change is:
C = $14
C) She spends $10, so now she has $10 less than before, the change is:

Column 2 has entries 4 minutes, 4 minutes, 4 minutes, 4 minutes, 4 minutes, 4 minutes, 4 minutes, 4 minutes, 4 minutes, 4 minutes.
Answer:
24 Minutes
Find 60 percent of 40.
Percent means over 100
,so 60% = 60/100 or 0.6
Multiply that by 40 to find 60% of it:
40 * 0.6 = 24

Step-by-step explanation:
Using the keywords;
'more than' (addition)
'a number' which we can consider a variable
and 'equals'
Answer: 8 + x =20
Step-by-step explanation: eight more than a number means 8 more than meaning plus, a number. So this is saying that 8 more than what ever that number is, will equal 20. We say x in the equation because x can be see as “the number”.
x = “the number” = 12
This is because 8 more than 12 is 20...

Answer:
True.
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Multiply the reciprocal of the fraction to both sides to isolate the variable, v.
The reciprocal in math is described as the quantity that is multiplied that will result in 1. In this case, you will multiply 5/2 to both sides of the equation:
[tex]\frac{2}{5}v = 4\\ \\(\frac{5}{2})\frac{2}{5}v = 4 * (\frac{5}{2})\\[/tex]
[tex]v = \frac{4 * 5}{2} = \frac{20}{2} = 10\\ v = 10[/tex] (True).
In this case, v = 10 will work to solve the given equation, and so it is true.

Question :-
After 24 years, Rama will be 5 times as old as he is now . Find his Present Age .Answer :-
Present Age of Rama is 6 Years .[tex] \rule {180pt} {2pt} [/tex]
Given :-
After 20 years, Rama will be 5 times as old as he is Now .To Find :-
Present Age of Rama = ?Solution :-
As per the provided information in the given question, we have been given that After 20 years, Rama will be 5 times as old as he is now. And, we have been aksed to calculate Present Age of Rama.
Let :-
The Present Age of Rama be x .Therefore :-
[tex] \longmapsto \: \: \:\sf{x \: + \: 24 \: = \: 5x} \\ [/tex]
[tex] \longmapsto \: \: \sf{24 \: = \: 5x \: - \: x} \\ [/tex]
[tex] \longmapsto \: \: \sf{24 \: = \: 4x} \\ [/tex]
[tex] \longmapsto \: \: \sf{x \: = \: \dfrac{24}{4} } \\ [/tex]
[tex] \longmapsto \: \: \textbf{ \textsf{x \: = \: 6 }} [/tex]
Hence :-
Present Age of Rama = 6 years .[tex] \underline {\rule {180pt} {4pt}} [/tex]
Given :
After 24 years, Rama will be 5 times as old as he is now .⠀
To Find :
Rama's Present Age .⠀
Solution :
Let us assume the present age of Rama as x years .So, 5 times of his age will be 5x years.Now,
⠀
According to the Question :
[tex]{ \longrightarrow {\qquad {\sf 5x = x + 24 }}}[/tex]
⠀
Subracting x from both sides we get :
[tex]{ \longrightarrow {\qquad {\sf 5x - x= x - x+ 24 }}}[/tex]
[tex]{ \longrightarrow {\qquad {\sf 4x= \cancel{x} \: \: \cancel{- x}+ 24 }}}[/tex]
[tex]{ \longrightarrow {\qquad {\sf 4x= 24 }}}[/tex]

Find the X
Answer:
X=10
Step-by-step explanation:
Step 1: Subtract 100 from both sides of the equation.
Step 2: Simplify.
Step 3: Subtract 25x from both sides of the equation.
Step 4: Simplify.
Step 5: Divide both sides of the equation by the same term.
Step 6: Simplify.
X=10 :)
Answer:
x = 10Step-by-step explanation:
In this question we are given an equation that is 22x + 100 = 25x + 70. And we are asked to find the value of x .
Solution : -
[tex] \longmapsto \:22x + 100 = 25x + 70 [/tex]
Step 1 : Subtracting 100 from both sides :
[tex] \longmapsto \:22x + \cancel{100} - \cancel{100} = 25x + 70 - 100[/tex]
On further calculations we get :
[tex] \longmapsto \: 22x = 25x - 30[/tex]
Step 2 : Subtracting 25x from both sides :
[tex] \longmapsto \:22x - 25x = \cancel{ 25x} - \cancel{25x }- 30[/tex]
On further calculations we get :
[tex] \longmapsto \: \cancel{- }3x = \cancel{ - }30[/tex]
Step 3 : Dividing with 3 on both sides :
[tex] \longmapsto \: \frac{ \cancel{3}x}{ \cancel{3}} = \cancel{\frac{30}{3} }[/tex]
On further calculations we get :
[tex] \longmapsto \: \purple{\boxed{ \frak{x = 10}}}[/tex]
Henceforth , value of x is 10 .Verifying : -
We're verifying our answer by substituting value of x in given equation . So ,
22x + 100 = 25x + 7022 ( 10 ) + 100 = 25 ( 10 ) + 70220 + 100 = 250 + 70320 = 320L.H.S = R.H.S Hence, Verified.Therefore, our value for x is correct .

x = number of t- shirts
the function for the incurring costs is
c = 5x + 45
the function for the accumulating sale is
s = 20x
the break even point is when both functions deliver the same result.
20x = 5x + 45
15x = 45
x = 3
c = s = 5×3 + 45 = 20×3 = $60
they need to sell 3 t-shirts to break even.
at that point they will have incurred $60 in costs and collected the same amount in sales.
