The probability that a randomly chosen person from the given population makes a purchase is [tex]\left(\begin{array}{ccc}p\\1\end{array}\right)[/tex] *0.25.
We can calculate the probability in the following way,
Let the total population of visitors visiting to the online shopping site be P.
The estimated odds of visitors making a purchase on the online shopping website are 0.25
P(E)=0.25 and n=P
We know that the probability mass function is also known as p.m.f. of Binomial Distribution with parameters n and P.
P(X=x) = [tex]\left(\begin{array}{ccc}n\\x\end{array}\right){p^x}[/tex]* [tex](1-p)^{(1-x)}[/tex] ; 0 < p < 1 And x=0,1,2,3,...
Probability of one randomly chosen visitor making a purchase= P(x=1)
=[tex]\left(\begin{array}{ccc}p\\1\end{array}\right)[/tex] 0.25^1 * 0.75^0
=[tex]\left(\begin{array}{ccc}p\\1\end{array}\right)[/tex]*0.25
Therefore, the Probability of a random visitor making a purchase depends on the value of the population and is equal to [tex]\left(\begin{array}{ccc}p\\1\end{array}\right)[/tex] * 0.25

a force of 10 pounds compresses a 21-inch spring 8 inches. how much work is done in compressing the spring from a length of 15 inches to a length of 13 inches?
The work is done in compressing the spring from a length of 15 inches to a length of 13 inches are the 0.897ftlb.
Work Done:According to the paintings-power theorem, the internet paintings performed on an item equals the alternate withinside the power of the item . If the simplest alternate withinside the power located is withinside the capability power (say U) of the item, then the internet paintings performed W=△U.
Answer and Explanation:When a spring is compressed x in with the aid of using a pressure F,
F=kx, where k is the spring constant.
Since it's miles for the reason that the spring is compressed to 8in from 21in, that is, a compression of (21−eight)=13in, we obtain
F=kx⇒k=Fx=10lb1312ft=12013lbft−1.
Using the theorem, the internet paintings performed on an item equals the alternate withinside the power of the item. In this situation the simplest alternate in power is withinside the capability power of the spring while it's miles compressed with the aid of using x gadgets of duration, which is 12kx2. (k is the spring constant.)
The capability power of the spring while it's miles compressed to 15cm=0.5k(21−1512)2
The capability power of the spring while it's miles compressed to 13cm=0.5k(21−1312)2
Work Done equals the alternate withinside the capability power while it's miles compressed from 15in to 13in
=0.5k[(21−1312)2−(21−1512)2]=0.512013[(21−1312)2−(21−1512)2]≈ 0.897ftlb

the length of a rectangle is 7 inches more than the width. the perimeter is 38 inches. find the length and the width of the rectangle.
A rectangle's length is 7 inches longer than its width. the perimeter is 38 inches. the length is 13 inches and the width of the rectangle is 12 inches
width = (38 - 14) / 2 = 12 inches
length = (38 - 12) / 2 = 13 inches
to find the length and width of the rectangle given that the length is 7 inches more than the width, and the perimeter is 38 inches, we can use the formula for perimeter (2 x length + 2 x width = perimeter). Plugging in the values given, we get 2 x length + 2 x width = 38. Solving for width, we get width = (38 - 14) / 2 = 12 inches. Plugging this value into the original equation, we get length = (38 - 12) / 2 = 13 inches. Therefore, the length and width of the rectangle are 13 inches and 12 inches, respectively.

What is the equation, in slope-intercept form, for a line that passes through the point (9,2) and (3, -2)
A: y = 2/3 x - 4
B: y = - 2/3 x - 4
C: y = 3/2 x + 4
D: y = - 3/2 x + 4
Answer: The answer is therefore (B) y = - 2/3 x - 4.
Step-by-step explanation: To find the equation of the line in slope-intercept form, we can use the point-slope form of a line:
y - y1 = m(x - x1)
where (x1, y1) is a point on the line and m is the slope of the line.
In this case, we are given the points (9,2) and (3,-2). We can use either point as (x1, y1), but let's use (9,2) as the point. The slope of the line is the difference in y-values divided by the difference in x-values:
m = (y2 - y1) / (x2 - x1) = (-2 - 2) / (3 - 9) = -4/6 = -2/3
Substituting this value for m and the coordinates of (9,2) for (x1, y1) into the point-slope form of a line, we get:
y - 2 = -2/3(x - 9)
Distributing the -2/3 on the right side, we get:
y - 2 = -2/3x + 6
Adding 2 to both sides, we get:
y = -2/3x + 8
This is the equation of the line in slope-intercept form. The answer is therefore (B) y = - 2/3 x - 4.

A plane takes 30 seconds to fly a distance of 8 kilometres.
Work out the average speed of the plane, in miles per hour
Answer: 4.97 / 0.00833 = 597.77 miles per hour.
Step-by-step explanation:
To find the average speed of the plane in miles per hour, we first need to convert the distance the plane travels from kilometers to miles. One mile is equal to 1.609 kilometers, so 8 kilometers is equal to 8 / 1.609 = 4.97 miles.
Next, we need to convert the time the plane takes to travel this distance from seconds to hours. There are 3600 seconds in an hour, so 30 seconds is equal to 30 / 3600 = 0.00833 hours.
To find the average speed of the plane in miles per hour, we can now divide the distance the plane travels by the time it takes to travel that distance. This gives us 4.97 / 0.00833 = 597.77 miles per hour.
The Buffett Rule: Wealthy individuals often hire good accountants who find loopholes to lower their taxes. In addition, income from investments (e.g. Warren Buffett's fortune) is taxed differently than normal income. In 2011, Warren Buffett wrote an op-ed in the New York Times entitled, "Stop Coddling the Super-Rich." In it, he proposed what became known as the Buffett Rule: Tax codes must guarantee that the wealthy pay a higher dollar amount and a higher percent of their income in taxes. To do this, he suggested closing tax loopholes and raising taxes on investments. Discussion: Do you agree with Buffett that the wealthy should pay not only a higher dollar amount in taxes, but also a higher percent of their income in taxes? Why or why not?
Answer:
No, I do not agree with Buffett as the wealthy barely have any struggles, and them only paying less than a dollar in taxes will make the government add to the less fortunate. Meaning: If a large number of people aren't paying taxes, the government would not be getting a certain amount of money p/m&yr (per month and year), and that's a huge problem because hundreds of thousands of dollars are being spent every day. And where does the government get that income? We, the givers. And so if they aren't reaching that expectation, where will they get it from? And it's likely that they will add to the less fortunate. Which is terrible. That can lead to putting thousands of people in debt leaving them miserable with nothing

Rewrite tan 0 x csc 0 in terms of sine and cosine.
tan 0. csc 0 = ?
(Simplify your answer.)
pls help asap i can’t pass this class without passing this test
To rewrite the expression tan 0 x csc 0 in terms of sine and cosine, we can use the following trigonometric identities:
The reciprocal identity: csc 0 = 1/sin 0
The tangent identity: tan 0 = sin 0/cos 0
The Pythagorean identity: sin^2 0 + cos^2 0 = 1
Substituting these identities into the given expression, we get:
tan 0. csc 0 = (sin 0/cos 0) * (1/sin 0)
Using the reciprocal identity and the Pythagorean identity, we can simplify this expression further to get:
tan 0. csc 0 = (sin 0 * 1)/(cos 0 * sin 0)
Next, we can cancel out the sin 0 term on the numerator and denominator to get:
tan 0. csc 0 = 1/cos 0
Finally, we can use the Pythagorean identity again to rewrite the denominator as:
tan 0. csc 0 = 1/sqrt(1 - sin^2 0)
Therefore, the final simplified expression is:
tan 0. csc 0 = 1/sqrt(1 - sin^2 0)
This is the final answer.

which shows how the distributive property can be used to evaluate 7 times 8 and four-fifths? 56 startfraction 28 over 5 endfraction
56 * (28/5) shows how the distributive property can be used to evaluate 7 times 8 and four-fifths.
7 times 8 = 56
4/5 = 28/5
Using the distributive property:
7 * 8 * (4/5) = (7 * 8) * (4/5) = 56 * (4/5) = 56 * (28/5) = 56 startfraction 28 over 5 endfraction
The distributive property states that for any numbers a, b, and c, a * (b + c) = a * b + a * c. To evaluate 7 times 8 and four-fifths, we can use the distributive property to separate the two factors. First, we calculate 7 times 8, which is equal to 56. Then, we calculate four-fifths, which is equal to 28/5. We then use the distributive property to multiply the two factors together, which is (7 * 8) * (4/5). This simplifies to 56 * (4/5) which is equal to 56 startfraction 28 over 5 endfraction.
