Answer:
A number that measures the likelihood that the event will occur.
Step-by-step explanation:
Probability is a measure of the frequency of occurrence of a phenomenon, the value of which can be expressed qualitatively or quantitatively. Probability is quantified as a real number between 0 and 1, although sometimes probability is also expressed as a percentage. The probability is 0 when the event cannot or will never happen, and the probability is 1 when it happens for sure or it always happens. If the probability is between these values, the event is not common and its occurrence is uncertain. The higher the probability value, the more common the event is or the more certain it will occur.
Below is a data set containing six observations in ascending order
33 44 51 62 71 X
Find the value of missing data value X, if the range of data is 58
========================================================
Explanation:
The observations are in ascending order, which means the set is sorted from smallest to largest.
The X is at the right-most endpoint, so X is the largest value (aka the max).
The min is 33, so,
max - min = range
X - 33 = 58
X = 58+33
X = 91 is the max
Answer:
Step-by-step explanation:
The range of the data is the highest value - the lowest value.
The lowest in the list is 33 so the highest must be 33 + 58
= 91.
Create a system of equations whose solution is (2,-4).
Answer:
x=-4 and y=2 Those 2 equations when graphed give a vertical line and a horizontal line that intersect at the point (-4,2)
x+4=0 and y-2=0 are the same two lines.
or if you want more complicated systems of equations, with the same solution:
x+y=-2 and x-y=-6
in standard form, that's y=-x-2 and y=x+6 Graph those two lines and they intersect at (-4,2)
Those 2 lines are with slopes of -1 and +1. Those 2 equations are a system of equations
whose solution is x=-4 and y=2.
Rotate two perpendicular lines around the point (-4,2) and you get more systems of
equations with the same solution.
They don't have to be perpendicular though. x+y=-2 and x=-4 are two lines forming
a 45 degree angle, with the same solution (-4,2)
They don't have to be linear either. Take a parabola with the vertex (-4,2) and the line x=-4.
They intersect at the point (-4,2). That parabola could be the simple y=x2 shifted up and
to the left, to y-2 = (x+4)2 or y=x2+8x+18 or it could be any one of a family of parabolas with
the same vertex.
You could have 2 circles tangent at the point (-4,2) Endless circles could have that point
as a tangent and their equations having that same solution (-4,2)

Annual starting salaries for college graduates with degrees in business administration are generally expected to be between $10,000 and $50,000. Assume that a 95% confidence interval estimate of the population mean annual starting salary is desired. Determine the planning value for the population standard deviation.
1. Determine how large a sample should be taken if the desired margin of error is:
a. $500
b. $200
c. $100
2. Would you recommend trying to obtain the $100 margin of error? Explain
Answer:
1) the planning value for the population standard deviation is 10,000
2)
a) Margin of error E = 500, n = 1536.64 ≈ 1537
b) Margin of error E = 200, n = 9604
c) Margin of error E = 100, n = 38416
3)
As we can see, sample size corresponding to margin of error of $100 is too large and may not be feasible.
Hence, I will not recommend trying to obtain the $100 margin of error in the present case.
Step-by-step explanation:
Given the data in the question;
1) Planning Value for the population standard deviation will be;
⇒ ( 50,000 - 10,000 ) / 4
= 40,000 / 4
σ = 10,000
Hence, the planning value for the population standard deviation is 10,000
2) how large a sample should be taken if the desired margin of error is;
we know that, n = [ ([tex]z_{\alpha /2[/tex] × σ ) / E ]²
given that confidence level = 95%, so [tex]z_{\alpha /2[/tex] = 1.96
Now,
a) Margin of error E = 500
n = [ ([tex]z_{\alpha /2[/tex] × σ ) / E ]²
n = [ ( 1.96 × 10000 ) / 500 ]²
n = [ 19600 / 500 ]²
n = 1536.64 ≈ 1537
b) Margin of error E = 200
n = [ ([tex]z_{\alpha /2[/tex] × σ ) / E ]²
n = [ ( 1.96 × 10000 ) / 200 ]²
n = [ 19600 / 200 ]²
n = 9604
c) Margin of error E = 100
n = [ ([tex]z_{\alpha /2[/tex] × σ ) / E ]²
n = [ ( 1.96 × 10000 ) / 100 ]²
n = [ 19600 / 100 ]²
n = 38416
3) Would you recommend trying to obtain the $100 margin of error?
As we can see, sample size corresponding to margin of error of $100 is too large and may not be feasible.
Hence, I will not recommend trying to obtain the $100 margin of error in the present case.

Use this formula
a & b/c = (a*c+b)/c
to convert from a mixed number to an improper fraction
So,
a & b/c = (a*c+b)/c
3 & 3/4 = (3*4+3)/4
3 & 3/4 = 15/4
---------------------------------------------------
Next, we add the fractions 15/4 and 5/6. The denominators aren't the same, so we can't add right away. We need to get the denominators to the LCD.
In this case, the LCD is 4*6 = 24
The fraction 15/4 becomes 90/24 after multiplying top and bottom by 6.The fraction 5/6 becomes 20/24 after multiplying top and bottom by 4Now we can add the fractions:
90/24+20/24 = (90+20)/24 = 110/24
---------------------------------------------------
So far, we've added the 3&3/4 portion to the 5/6 portion to get the result 110/24
The last thing to do is to add on the two 1/3 ft pieces, which means we're adding on 2/3 of a foot
2/3 = 16/24 after multiplying top and bottom by 8
Add this to the result of the last section
110/24+16/24 = (110+16)/24 = 126/24
---------------------------------------------------
From here, we convert the improper fraction 126/24 to decimal form
Using a calculator, you should find that 126/24 = 5.25
The result is larger than 5, which means she used too much ribbon. There won't be enough ribbon to do everything she wants to do.
---------------------------------------------------
The shortcut we can take is to type the following into the calculator
3+3/4+5/6+2/3
doing so should lead to 5.25
Answer:
Yes
Step-by-step explanation:
So at the begining, Cherly has 60 in (12inx5ft) of ribbon. She uses 45 in(3.75x12) to make the hair bow, leaving 15 in of ribbon. She, then, uses 10 in (5/6x12) of ribbon, leaving 5 in. After that, Cheryl uses 8 in [2(1/3x12)] to put on the picture frame, leaving two inches of ribbon.
Can anyone explain "Predicting Results of Rigid Transformations"?
Answer: Rigid just means that the whole shape goes through the same transformation, so with rotations, reflections, and translations, the shape should not change at all, just in a different place or orientation.
In a translation, ALL of the points move the same distance in the same direction. A translation is called a rigid transformation or isometry because the image is the same size and shape as the pre-image. ... In addition, the corresponding segment sides of the pre-image and image are parallel.
A rigid transformation preserves both the side lengths and the angle measures of a polygon. Step-by-step explanation: Rigid transformations are the transformations which does not affect the size and the shape of figure . The figure doesn't shrink or get enlarger.
There are three different types of transformations: translation, reflection, and rotation.
The distance from each point in the figure to the center of rotation is preserved. A rigid transformation is a transformation that preserves congruence.

You decide to make a side business of selling face mask. The marginal cost for making a mask is $0.50 per mask. The total cost to to make 100 mask is hours is $62. You decide to sell the mask for $3 a mask.
Required:
a. Find the linear cost function C(x).
b. Find the revenue function R(x).
c. How many mask must be made to break even. State in a complete sentence using the context of the problem.
d. Determine the interval of profit and loss. State in a complete sentence using the context of the problem
Given:
Marginal cost for making 1 mask = $0.50
Total cost to make 100 masks = $62
Revenue per mask = $3
To find:
(a) Linear cost function C(x)
(b) Revenue function R(x)
(c) Break even point
(d) Interval of profit & loss
Solution:
(a) We know that linear cost function is given by,
Total cost = Fixed cost per unit + (Marginal cost per unit)*(Number of units)
Let 'x' denote the number of units
[tex]\Rightarrow[/tex] C(x) = b + mx
It is given that, m = $0.50
[tex]\Rightarrow[/tex] C(x) = b + 0.5x
It is also given that the total cost of making 100 masks is $62
[tex]\Rightarrow[/tex] C(100) = $62
[tex]\Rightarrow[/tex] b +0.5(100) = 62
[tex]\Rightarrow[/tex] b + 50 =62
[tex]\Rightarrow[/tex] b = 62 - 50
[tex]\Rightarrow[/tex] b = 12
[tex]\Rightarrow[/tex] C(x) = 12 + 0.5x
This is the linear cost function, C(x)
(b) We know that,
Total Revenue = Revenue per unit * Number of units
It is given that a mask is sold for $3, i.e., revenue per mask is $3
Let 'x' denote the number of units
Then the revenue function is given by,
R(x) = 3x
This is the revenue function, R(x)
(c) We know that, break even point refers to the point where total cost is equal to the total revenue. Thus, at break even point, we have,
C(x) = R(x)
[tex]\Rightarrow[/tex] 12 + 0.5x = 3x
[tex]\Rightarrow[/tex] 3x - 0.5x = 12
[tex]\Rightarrow[/tex] 2.5x = 12
[tex]\Rightarrow x=\frac{12}{2.5}[/tex]
[tex]\Rightarrow[/tex] x = 4.8
Since, 'x' denotes the number of masks, it must be a whole number and not a fraction. Thus, we will round off our value to get the break even point as 5 masks.
That is, 5 masks must be made to break even.
(d) We know that the profit function is given as the difference of revenue function and cost function. That is, we have,
P(x) = R(x) - C(x)
[tex]\Rightarrow[/tex] P(x) = 3x - (12 + 0.5x)
[tex]\Rightarrow[/tex] P(x) = 3x - 12 - 0.5x
[tex]\Rightarrow[/tex] P(x) = 2.5x -12
Now, we know that there is profit when the value of the profit function is positive & there is loss when the value of profit function is negative. Thus, we can calculate the intervals of profit and loss by finding the intervals where the profit function is positive & negative respectively. Alternatively, since the break even point denotes the point where the value of the profit function is 0, we can find the intervals of profit and loss as the intervals greater than and lesser than the break even point respectively.
That is, since the break even point is x = 4.8, the interval of profit is given as x > 4.8 & the interval of loss is given as x < 4.8
Taking into account that 'x' denotes the number of masks and thus must be a whole number, we have the intervals of profit and loss as,
Loss:= [tex]x \in [0,4][/tex]
Profit:= [tex]x \in [5, \infty)[/tex]
Final answer:
(a) Linear Cost function: C(x) = 12 + 0.5x
(b) Revenue function: R(x) = 3x
(c) 5 masks must be made to break even
(d) Interval of profit: [tex]x \in [5, \infty)[/tex], Interval of loss: [tex]x \in [0,4][/tex]
Solve for y.
r/3-2/y=s/5
Answer:
y = 2 / (r/3 - s/5)
Step-by-step explanation:
r/3 - 2/y = s/5
add 2/y to both sides
r/3 = s/5 + 2/y
Subtract s/5 from both sides
r/3 - s/5 = 2/y
multiply both sides by y
y(r/3 - s/5) = 2
Divide both sides by r/3 - s/5
y = 2 / (r/3 - s/5)

Dao receives an employee discount on the purchase of a new automobile. The automobile that he is interested in has
a sticker price of $18,560. If his discount is 18 percent, what is the price that Dao will pay?
Answer: $15219.20
Step-by-step explanation:
Based on the information given, firstly we need to calculate the discount which will be:
= 18% × $18560
= 0.18 × $18560
= $3340.80
Then, the amount that Dao will pay will be:
= Sticker price - Discount
= $18560 - $3340.80
= $15219.20
Therefore, Dao will pay $15219.20

Step-by-step explanation:
Given
Price list on slacks is $22
Price list on jumpers is $37
Store ordered 30 pairs of slacks and 40 Jumpers
Total price becomes
[tex]\Rightarrow 22\times 30+37\times 40\\\Rightarrow \$2140[/tex]

Answer:
x = 35
Step-by-step explanation:
x and 3x+40 are same side interior angles and same side interior angles are supplementary when the lines are parallel
x + 3x+40 = 180
Combine like terms
4x+40 =180
4x = 180-40
4x = 140
Divide by 4
4x/4 = 140/4
x = 35
Answer and Step-by-step explanation:
To solve for x, we add together the angles, and equal it to 180.
This is because the angles shown are same side interior angles, and add up to 180 degrees.
x + 3x + 40 = 180
Subtract 40 and combine like terms.
4x = 140
Divide 4 from both sides of the equation.

We want to find:
[tex]\lim_{n \to \infty} \frac{\sqrt[n]{n!} }{n}[/tex]
Here we can use Stirling's approximation, which says that for large values of n, we get:
[tex]n! = \sqrt{2*\pi*n} *(\frac{n}{e} )^n[/tex]
Because here we are taking the limit when n tends to infinity, we can use this approximation.
Then we get.
[tex]\lim_{n \to \infty} \frac{\sqrt[n]{n!} }{n} = \lim_{n \to \infty} \frac{\sqrt[n]{\sqrt{2*\pi*n} *(\frac{n}{e} )^n} }{n} = \lim_{n \to \infty} \frac{n}{e*n} *\sqrt[2*n]{2*\pi*n}[/tex]
Now we can just simplify this, so we get:
[tex]\lim_{n \to \infty} \frac{1}{e} *\sqrt[2*n]{2*\pi*n} \\[/tex]
And we can rewrite it as:
[tex]\lim_{n \to \infty} \frac{1}{e} *(2*\pi*n)^{1/2n}[/tex]
The important part here is the exponent, as n tends to infinite, the exponent tends to zero.
Thus:
[tex]\lim_{n \to \infty} \frac{1}{e} *(2*\pi*n)^{1/2n} = \frac{1}{e}*1 = \frac{1}{e}[/tex]

Kevin paid $2.52 for 6 juice boxes. How much should Kevin expect to pay for 18 juice boxes?
Answer:
7.56
Step-by-step explanation:
Kevin should expect to pay approximately $7.56 for 18 juice boxes based on the given information.
To find out how much Kevin should expect to pay for 18 juice boxes based on the given information, we can set up a proportion using the number of juice boxes and the cost:
In general, an expression refers to a combination of symbols, numbers, variables, and operators that represent a specific computation or value. Expressions are a fundamental concept in mathematics, programming, and logic.
Let "x" be the cost of 18 juice boxes.
We have the proportion:
6 juice boxes / $2.52 = 18 juice boxes / x
To solve for "x," we can cross-multiply:
6x = 18 x $2.52
6x = $45.36
Now, divide both sides by 6 to isolate "x":
x = $45.36 / 6
x ≈ $7.56
Therefore, According to the data provided, Kevin should budget about $7.56 for 18 juice cartons.

The base of a triangle is 6 meters longer than the height of the triangle. If the area of the triangle is 108 square meters, what are the base and height of the triangle?
Answer:
36 meters
Step-by-step explanation:
A=1/2b×h
108sq. m=1/2.6m×h
both side canceling meter
h=2×108m/6
h=36m. answer
The height of the triangle is 12 meters, and the base of the triangle is 18 meters.
Let's denote the height of the triangle as "h" meters. According to the given information, the base of the triangle is 6 meters longer than the height, so the base can be represented as "(h + 6)" meters.
The area of a triangle is given by the formula: Area = (1/2) * base * height
We are given that the area of the triangle is 108 square meters, so we can write the equation as:
108 = (1/2) * (h + 6) * h
Now, let's solve for "h":
108 = (1/2) * (h² + 6h)
Multiply both sides by 2 to eliminate the fraction:
216 = h² + 6h
Rearrange the equation in standard quadratic form:
h² + 6h - 216 = 0
Now, let's solve this quadratic equation for "h." We can factor it or use the quadratic formula. Factoring, we get:
(h + 18)(h - 12) = 0
Setting each factor to zero:
h + 18 = 0 or h - 12 = 0
Solving for "h" in each case:
h = -18 (discard this negative value as height cannot be negative) or h = 12
Since height cannot be negative, we take the positive value of "h," which is 12 meters.
Now, we can find the base by using the given relationship: base = height + 6
base = 12 + 6 = 18 meters
So, the height of the triangle is 12 meters, and the base of the triangle is 18 meters.

Find the first three terms of the Maclaurin series for f(x) =
[tex]{e}^{ \frac{x}{2} } [/tex]
Step-by-step explanation:
Starting out with the Taylor series,
[tex]\displaystyle f(x) = \sum_{n=0}^{\infty} \dfrac{f^{(n)}(a)}{n!}(x-a)^n[/tex]
where [tex]f^{(n)}[/tex] is the nth derivative of f(x) and if we set a = 0, we get the special case of the Taylor series called the Maclaurin series:
[tex]\displaystyle f(x) = \sum_{n=0}^{\infty} \dfrac{f^{(n)}(0)}{n!}x^n[/tex]
Expanding this series up to the 1st 3 terms at a = 0,
[tex]f(x) = f(0) + \dfrac{f'(0)}{1!}x + \dfrac{f''(0)}{2!}x^2[/tex]
Let's find the derivatives of [tex]e^{\frac{x}{2}}[/tex]:
[tex]f'(x) = \frac{d}{dx} (e^{\frac{x}{2}}) = \frac{1}{2}e^{\frac{x}{2}} \Rightarrow f'(0) = \frac{1}{2}[/tex]
[tex]f''(x) = \frac{1}{4}e^{\frac{x}{2}} \Rightarrow f''(0) = \frac{1}{4}[/tex]
We can now write the Maclaurin series for [tex]e^{\frac{x}{2}}[/tex]as
[tex]e^{\frac{x}{2}} = 1 + \frac{1}{2} x + \frac{1}{8} x^2[/tex]
