Given:
The number of pink balls in the urn = 8.
The number of green balls in the urn = 6
The number of balls randomly drawn from the urn =5
Required:
We need to find the probability of selecting 5 balls that all are pink.
Explanation:
The balls are replaced after selection.
The sample space = the total number of balls in the urn= 8+6
\(n(S)=14\)Let A be the event of selecting a pink ball.
The favourable outcomes = The number of pink balls = 8
\(n(A)=8\)The probability of selecting 5 balls from an urn that all are pink,
\(=\frac{n(A)}{n(S)}\times\frac{n(A)}{n(S)}\times\frac{n(A)}{n(S)}\times\frac{n(A)}{n(S)}\times\frac{n(A)}{n(S)}\)\(=\frac{8}{14}\times\frac{8}{14}\times\frac{8}{14}\times\frac{8}{14}\times\frac{8}{14}\)\(=\frac{32768}{537824}\)\(=0.0609269947\)\(=0.061\)Final answer:
The probability that the 5 balls will be pink is 0.061.
4 times a number is 12 less than the square of that number. Find the positive solution.
Answer:
\(x = 6\)
Step-by-step explanation:
Given
Let the number be x.
So, we have:
\(4 * x\) ----- 4 times a number
\(= x^2 - 12\) --- 12 less than its square
The equation becomes
\(4x = x^2 - 12\)
Equate to o
\(x^2 - 4x - 12 = 0\)
Split
\(x^2 - 6x +2x - 12 = 0\)
Factorize
\(x(x - 6) +2(x - 6) = 0\)
Factor out x - 6
\((x + 2)(x - 6) = 0\)
Split
\(x + 2 = 0\ or\ x - 6 = 0\)
Solve for x
\(x = -2\ or\ x = 6\)
The positive value is 6

You want to enclose a rectangular region with an area of
1200 square feet and a length of 40 feet, 50 feet, or 60 feet.
Find the perimeter for each possible region. Explain why
you might rewrite the area formula to find the solutions.
The possible perimeters are 140 feet, 148 feet and 160 feet.
In order to determine the width that would be used to determine the possible perimeters, the formula for the area would have to be rewritten.
What are the possible perimeters?A rectangle is a 2-dimensional quadrilateral with four right angles and two diagonals that bisect each other at right angles.
Area of a rectangle = length x width
Width = area / length
1200 / 40 = 30 feet
1200 / 50 = 24 feet
1200 / 60 = 20 feet
Perimeter of a rectangle = 2 x (length + width)
Perimeter when width is 30 feet : 2(40 + 30) = 140 feet
Perimeter when width is 24 feet : 2(24 + 50) = 148 feet
Perimeter when width is 20 feet : 2 (20 + 60) = 160 feet

A square with sides measuring 7 millimeters each is drawn within the figure shown. A point within the figure is randomly selected.
What is the approximate probability that the randomly selected point will lie inside the square?
Responses
4.7%
4.7%
7.4%
7.4%
16.6%
16.6%
26.1%
Answer:
To find the probability that the randomly selected point will lie inside the square, we need to find the area of the square and the area of the figure, and then divide the area of the square by the area of the figure.
The area of the square is 7 mm x 7 mm = 49 mm^2.
To find the area of the figure, we can divide it into a rectangle and two right triangles. The rectangle has dimensions of 8 mm x 14 mm, so its area is 8 mm x 14 mm = 112 mm^2. Each right triangle has base 8 mm and height 6 mm, so each triangle has an area of (1/2) x 8 mm x 6 mm = 24 mm^2. The total area of the figure is therefore 112 mm^2 + 24 mm^2 + 24 mm^2 = 160 mm^2.
The probability of selecting a point inside the square is then 49 mm^2 / 160 mm^2, which is approximately 0.3063 or 30.63%.
Therefore, the answer is closest to 26.1%, which is the third option.

Step-by-step explanation:
Substitute f(4)=f(3)-1=(f(2)-1)-1=((f(1)-1)-1)-1=1-3=-2; Alternatively, find an explicit equation by noticing that f(n)=-n+2, since you minus 1 every time n increases by 1 (hence the -n), and now note with f(1)=-(1)+b, we have b=2 so its f(n)=-n+2, substituting gives -4+2=-2, thus we have also derived a general formula.

The solution to the system of linear equations is (x, y, z) = (64/11, 37/11, 9/11). The system has exactly one solution.
Let's solve the system of linear equations correctly.
The given system of linear equations is:
x = y + 3z = 6
x - 2y = 5
2x - 2y + 5z = 9
To determine the number of solutions, we can analyze the system using the method of elimination or substitution. Let's use the method of elimination:
From equation 1, we have:
x = y + 3z
Substituting this value of x in equation 2:
(y + 3z) - 2y = 5
y + 3z - 2y = 5
-z + 3z = 5 - y
2z = 5 - y
Now, let's substitute the value of x in equation 3:
2(y + 3z) - 2y + 5z = 9
2y + 6z - 2y + 5z = 9
11z = 9
Simplifying the equation, we find:
z = 9/11
Now, substituting this value of z back into the equation 2z = 5 - y, we get:
2(9/11) = 5 - y
18/11 = 5 - y
18/11 - 5 = -y
18/11 - 55/11 = -y
-37/11 = -y
y = 37/11
Finally, we can substitute the values of y and z into equation 1 to find the value of x:
x = y + 3z
x = 37/11 + 3(9/11)
x = 37/11 + 27/11
x = 64/11
Therefore, the solution to the system of linear equations is (x, y, z) = (64/11, 37/11, 9/11).
The system has exactly one solution.

Let q = demand for seats on a 500-seat airplane and p = price charged per ticket. Suppose that q = 600 - 3p and assume that the unit cost of flying a passenger is $50. To maximize profit from the flight, the airline should charge how much per ticket?
Answer:
$125Step-by-step explanation:
Given the equation q = 600 - 3p where;
q = demand for seats on a 500-seat airplane
p = price charged per ticket
Revenue = demand for seats * price charged per ticket i.e pq
Revenue = p * 600 - 3p ... 1
Cost of flying a passenger = unit cost * demand for seats = 50q
Cost of flying a passenger = 50q ...2
Profit generated will be the revenue less cost i.e Revenue - cost
Profit generated = p(600 - 3p) - 50q
= p(600 - 3p) - 50(600-3p)
= 600p-3p²-30000+150p
= -3p²+750p-30000
Profit P = -p²+250p-10000
To maximize the profit, dP/dp = 0
-2p+250 = 0
-2p = -250
p = $125
To maximize profit, the airline should charge $125 per ticket

The amount of money that Theresa has left is equal to £2,740.
How to write a linear equation to model this situation?In order to write a linear equation to describe this situation, we would assign variables to the cost of flights for each of them and the cost of accommodation for each of them respectively, and then translate the word problem into a linear equation as follows:
Let the variable a represent cost of flights for each of them.
Let the variable f represent cost of accommodation for each of them.
Since Theresa paid for herself and 11 friends to go on holiday with a flight cost of £339 and accommodation cost of £266, a linear equation to describe this situation is given by;
y = 12(a + b)
y = 12(266 + 339)
y = £7,260
For the amount of money left, we have:
Amount of money left = £10,000 - £7,260
Amount of money left = £2,740.

Lisa and Tomas Lopez are buying a new minivan that has a baseprice of $22,510. The options total $8,062 and the destinationcharge is $770. The dealer’s cost is estimated to be 91% of thebase price and 88% of the price of the options.a.What is the sticker price of the vehicle?b.Find the dealer’s percent of the base price.c.Find the dealer’s percent of the options price.d.What is the estimated dealer’s cost?
Given:
Base price = $22,150
Options total = $8,062
Destination charge = $770
Dealer's cost = 91% of base price and 88% of price options.
Let's solve for the following:
• (a) What is the sticker price of the vehicle?
Let's first find the dealers cost.
We have:
Dealers cost = (91% of base price) + (88% of price options)
Dealer's cost = (0.91 x 22150) + (0.88 x 8062)
= 20156.5 + 7094.56
= 27251.06
The dealer's cost is = $27251.06
To find the sticker price, we have:
Sticker cost = Base price + Options total + Destination charge
Sticker cost = 22150 + 8062 + 770
Sticker cost = 309

lim as x approaches 1
The limit of the given function as x approaches 1 is 0.
To find the limit of the given function as x approaches 1, we need to evaluate the expression by substituting x = 1. Let's break it down step by step:
1. Begin by substituting x = 1 into the numerator:
\(\[12\sin\left(\frac{\pi}{2}\cdot 1\right)\ln(1) = 12\sin\left(\frac{\pi}{2}\right)\ln(1) = 12(1)\cdot 0 = 0\]\)
2. Now, substitute x = 1 into the denominator:
(1³ + 5)(1 - 1) = 6(0) = 0
3. Finally, divide the numerator by the denominator:
0/0
The result is an indeterminate form of 0/0, which means further analysis is required to determine the limit. To evaluate this limit, we can apply L'Hôpital's rule, which states that if we have an indeterminate form 0/0, we can take the derivative of the numerator and denominator and then evaluate the limit again. Applying L'Hôpital's rule:
4. Take the derivative of the numerator:
\(\[\frac{d}{dx}\left(12\sin\left(\frac{\pi}{2}x\right)\ln(x)\right) = 12\left(\cos\left(\frac{\pi}{2}x\right) \cdot \left(\frac{\pi}{2}\right) \cdot \frac{-1}{x} + \frac{\sin\left(\frac{\pi}{2}x\right)\ln(x)}{x}\right)\]\)
5. Take the derivative of the denominator:
\(\[\frac{d}{dx}\left((x^3 + 5)(x - 1)\right) = \frac{d}{dx}\left(x^4 - x^3 + 5x - 5\right) = 4x^3 - 3x^2 + 5\]\)
6. Substitute x = 1 into the derivatives:
Numerator: \(\[12\left(\cos\left(\frac{\pi}{2}\right) \cdot \left(\frac{\pi}{2}\right) \cdot \frac{-1}{1} + \sin\left(\frac{\pi}{2}\right) \cdot \frac{\ln(1)}{1}\right) = 0\]\)
Denominator: 4(1)³ - 3(1)² + 5 = 4 - 3 + 5 = 6
7. Now, reevaluate the limit using the derivatives:
lim as x approaches 1 of \(\[\frac{{12\left(\cos\left(\frac{\pi}{2}x\right) \cdot \left(\frac{\pi}{2}\right) \cdot \frac{{-1}}{{x}} + \sin\left(\frac{\pi}{2}x\right) \cdot \frac{{\ln(x)}}{{x}}\right)}}{{4x^3 - 3x^2 + 5}}\]\)
= 0 / 6
= 0
Therefore, the limit of the given function as x approaches 1 is 0.

Ms. Keenan is a high school teacher who wants to know how much time students spend studying each day. She finds that the average student spends 3.00 hours a day studying (s - 0.75). Assuming that studying hours is normally distributed, what percentage of students study less than 2.50 hours a day?
© 25.14 percent
© 19.15 percent
© 10.93 percent
© 24.86 percent
The requried, percentage of students who study less than 2.50 hours a day is approximately 25.14 percent.
What is the Z -a score?A Z-score is stated as the fractional model of data point to the mean using standard deviations.
We need to convert 2.50 hours to a standard score (z-score) using the formula,
z = (x - μ) / σ
where x is the value we want to convert, μ is the mean, and σ is the standard deviation.
z = (2.50 - 3.00) / 0.75
z = -0.67
This means that 2.50 hours is 0.67 standard deviations below the mean.
We can use a standard normal distribution table or a calculator to find the percentage of the distribution that falls below this standard score. For example, using a standard normal distribution table, we can look up the area to the left of z = -0.67 and get:
P(z < -0.67) = 0.2514
So the correct answer is (a) 25.14 percent.

a line with y-intercept (0,1) which passes for thought the point (1,1)
Answer:A unique line is defined by any two distinct (not identical) points. You have two distinct, which means you have a line. To find the equation for the line, we start with the slope-intercept equation for a line. This is only a template for a generic line, so we will have to find the specific values of m (slope) and b (y-intercept) that define your line.
The template: y = mx + b
b is the y-intercept, which, if you look at (0,–2), you will see is –2; it is where the line crosses the y-axis. Fill that value of b into our template to get:
y = mx – 2
Now, we only need the value of m, which is the slope. If you have two points on a line, you can calculate the slope of that line. The slope is the change (difference) of y over the change in x (difference) of x for two given points on the line. It's a fraction or ratio though sometimes it can be reduced to an integer.
So, taking your two points, you calculate the slope, m, in the following way:
(x1,y1) = (0,–2)
(x2,y2) = (5,1)
y2 – y1 1 – (–2) 1 + 2 3
m = ________ = ________ = ________ = ____
