A shop gave different discounts to different customers. Libby paid $600 for a watch at a discount of 20%. However, Scott paid $630 for the same watch. How many percent discount was given to Scott?

Answers

Answer 1

Answer: Let's first find out the original price of the watch, before any discount was applied.

Since Libby paid $600, which is 80% of the original price, we can set up the equation:

0.8P = 600

where P is the original price of the watch.

Solving for P, we get:

P = 600/0.8 = $750

So the original price of the watch was $750.

Now, we can find the discount that was given to Scott. He paid $630, which is a discount from the original price of:

$750 - $630 = $120

So the discount amount was $120.

To find the percentage discount, we can use the formula:

Discount percentage = (discount amount / original price) x 100%

Plugging in the values, we get:

Discount percentage = (120 / 750) x 100% = 16%

Therefore, Scott received a 16% discount on the watch.

Answers

Using Bayes theorem, the probability that the person passed through the radar trap located at L2 given that she received a speeding ticket is 0.059 or 5.9%.

What is the probability that the person passed through the radar trap located at L2

We can solve this problem using Bayes' theorem. Let A be the event that the person received a speeding ticket, and Bi be the event that the radar trap was set at location Li, for i = 1, 2, 3, or 4. Then we want to find the conditional probability of B22 given A, which is:

[tex]P(B_2 | A) = P(A | B_2) * P(B_2) / P(A)[/tex]

We can compute each of the probabilities on the right-hand side using the given information.

First, we have:

[tex]P(B_1) = 0.4, P(B_2) = 0.2, P(B_3) = 0.3, P(B_4) = 0.4[/tex]

Next, we have:

[tex]P(A | B_1) = 0.3, P(A | B_2) = 0.1, P(A | B_3) = 0.4, P(A | B_4) = 0.2[/tex]

Finally, we have:

[tex]P(A) = P(A | B_1) * P(B_1) + P(A | B_2) * P(B_2) + P(A | B_3) * P(B_3) + P(A | B_4) * P(B_4)\\= (0.3 * 0.4) + (0.1 * 0.2) + (0.4 * 0.3) + (0.2 * 0.4)\\= 0.34[/tex]

Plugging these values into Bayes' theorem, we get:

[tex]P(B_2 | A) = P(A | B_2) * P(B_2) / P(A)\\= (0.1 * 0.2) / 0.34\\= 0.059\\[/tex]

Therefore, the probability that the person passed through the radar trap located at L2 given that she received a speeding ticket is 0..059 or 5.9%.

a trapezoid is shown with bases AD and BC. if slopCe of AD is 1/2, what is the slope of BC

Answers

The slope of BC is 1/2, since the slope of AD is 1/2. This is because the rise and run of the two bases are the same.

What is slope?

The slope of a line is defined as the ratio of the vertical change (the rise) to the horizontal change (the run).

In the case of an isosceles trapezoid, the two bases (AD and BC) are parallel and of equal length. Therefore, the slope of the two bases is the same.

Given that the slope of AD is 1/2, the slope of BC is also 1/2.

This is because the rise and run of the two bases are the same. Therefore, the ratio of rise to run is the same and the slope of both bases is 1/2.

To understand this better, let us consider the rise and run of the two bases:

AD: Rise = y² − y1, Run = x² − x1

BC: Rise = y² − y1, Run = x² − x1

Therefore,

Slope of AD = (y² − y1)/(x² − x1)

Slope of BC = (y² − y1)/(x² − x1)

Since the rise and run of the two bases are the same, the slope of the two bases is also the same.

Therefore, the slope of BC is 1/2, since the slope of AD is 1/2.

Find the possible values of a and the corresponding values of b.
(Answers are a= -3 , 2 and b= -18 , 12. But I don't know how to show the working so please help, thx)​

Answers

The possible values of a and the corresponding values of b are; a= -3, 2 and b= -18, 12.

How to calculate possible and the corresponding values?

Expanding the left-hand side of the equation:

(a + 3√5)² + a - b√5 = a² + 6a√5 + 45 + a - b√5

Combining like terms:

2a² + (2a - b)√5 + 45 = 51

Simplifying further:

2a² + (2a - b)√5 = 6

Now, since √5 is irrational, the only way the left-hand side can equal 6 is if both the rational and irrational parts are equal to 0. Therefore two equations:

2a² + 2a - b = 0 (Equation 1)

2a - b = 0 (Equation 2)

Solving Equation 2 for b:

b = 2a

Substituting this into Equation 1:

2a² + 2a - 2a = 0

Simplifying:

2a² = 0

Thus, a = 0 is a solution. However, a = 0 does not satisfy the original equation, since the left-hand side would be 45, which is not equal to 51. Therefore, we can divide both sides of Equation 1 by 2a to get:

a + 1 - b/2a = 0

Multiplying both sides by 2a:

2a² + 2a - b = 0

Substituting b = 2a:

2a² + 2a - 2a = 0

Simplifying:

2a² = 0

Thus, a = 0 is a solution. However, as noted above, a = 0 does not satisfy the original equation. Therefore, we must consider the case where a ≠ 0. Dividing both sides of Equation 2 by 2:

a - b/2 = 0

Solving for b:

b = 2a

Substituting into the original equation:

(a + 3√5)² + a - 2a√5 = 51

Expanding:

a² + 6a√5 + 45 + a - 2a√5 = 51

Combining like terms:

a² + 7a√5 - 6 = 0

Using the quadratic formula:

a = (-7√5 ± √(7²√5² - 4(1)(-6))) / 2(1)

Simplifying:

a = (-7√5 ± 13) / 2

Therefore, the possible values of a are -3 and 2. For each value of a, we can use b = 2a to find the corresponding value of b. Thus, the possible values of b are -18 and 12.

Four part spinner is spun twice total number of possible outcomes. What is the probability of spinning pink on both spins? What is the probability of not spinning orange either spin?

Answers

Probability of spinning pink on both spins = 1/4 and Probability of not spinning orange on either spin = 9/16.

What is probability?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen.

If a four-part spinner is spun twice, there are 16 possible outcomes (4 options on the first spin, multiplied by 4 options on the second spin).

To find the probability of spinning pink on both spins, we need to first determine how many outcomes result in pink on both spins. If we label the four parts of the spinner A, B, C, and D, and assume that pink is on part A, then there are four possible outcomes where pink appears on both spins: AA, AB, AC, and AD. Each of these outcomes has a probability of 1/16, since there are 16 total possible outcomes. So the probability of spinning pink on both spins is:

Probability of spinning pink on both spins = (number of outcomes where pink appears on both spins) / (total number of possible outcomes)

Probability of spinning pink on both spins = 4/16

Probability of spinning pink on both spins = 1/4

To find the probability of not spinning orange either spin, we need to determine how many outcomes do not have orange. If we assume that orange is on part B, then there are three outcomes on the first spin that do not result in orange: AB, AC, and AD. On the second spin, there are again three outcomes that do not result in orange: BA, CA, and DA. So there are a total of 3 x 3 = 9 outcomes where orange does not appear on either spin.

Again, each of these outcomes has a probability of 1/16, so the probability of not spinning orange on either spin is:

Probability of not spinning orange on either spin = (number of outcomes where orange does not appear on either spin) / (total number of possible outcomes)

Probability of not spinning orange on either spin = 9/16

Answers

Amount Due at Maturity a. $102,000, b. $30,100, c. $62,620, d. $42,930, e. $40,700.

Describe Interest?

Interest is the cost of borrowing money, typically expressed as a percentage of the borrowed amount, called the principal. It is the amount charged by a lender to a borrower for the use of money over a certain period of time. Interest can also refer to the amount earned on money that is invested, such as in a savings account or a bond. The rate of interest depends on factors such as the level of risk associated with the loan, the length of the loan period, and the market rate of interest at the time of borrowing. The amount of interest paid or earned can be calculated using various formulas, including simple interest and compound interest.

To determine the due date and amount of interest due at maturity for each note, we can use the following formula:

Interest = Principal x Rate x Time

where Principal is the face amount of the note, Rate is the annual interest rate, and Time is the time in years (based on a 360-day year).

a. January 5, $100,000, 6%, 120 days

Due Date: May 5

Time: 120/360 = 1/3 year

Interest = $100,000 x 0.06 x 1/3 = $2,000

Amount Due at Maturity = Principal + Interest = $100,000 + $2,000 = $102,000

b. February 15, $30,000, 4%, 30 days

Due Date: March 17 (assuming non-leap year)

Time: 30/360 = 1/12 year

Interest = $30,000 x 0.04 x 1/12 = $100

Amount Due at Maturity = Principal + Interest = $30,000 + $100 = $30,100

c. May 19, $62,000, 8%, 45 days

Due Date: July 3

Time: 45/360 = 1/8 year

Interest = $62,000 x 0.08 x 1/8 = $620

Amount Due at Maturity = Principal + Interest = $62,000 + $620 = $62,620

d. August 20, $42,400, 5%, 90 days

Due Date: November 18

Time: 90/360 = 1/4 year

Interest = $42,400 x 0.05 x 1/4 = $530

Amount Due at Maturity = Principal + Interest = $42,400 + $530 = $42,930

e. October 19, $40,000, 7%, 90 days

Due Date: January 17

Time: 90/360 = 1/4 year

Interest = $40,000 x 0.07 x 1/4 = $700

Amount Due at Maturity = Principal + Interest = $40,000 + $700 = $40,700

Therefore, the due date and amount of interest due at maturity for each note are as follows:

a. Due Date: May 5, Interest: $2,000, Amount Due: $102,000

b. Due Date: March 17, Interest: $100, Amount Due: $30,100

c. Due Date: July 3, Interest: $620, Amount Due: $62,620

22. Morality In a recent poll, the Gallup Organization found
that 45% of adult Americans believe that the overall state of
moral values in the United States is poor. Suppose a survey of a random sample of 500 adult Americans is conducted in which they are asked to disclose their feelings on the overall state of moral values in the United States. Use the normal approximation to the binomial to approximate the probability that

(a) exactly 250 of those surveyed feel the state of morals is poor.
(b) no more than 220 of those surveyed feel the state of morals is poor.
(c) more than 250 of those surveyed feel the state of morals is poor.
(d) between 220 and 250, inclusive, believe the state of morals is poor.
(e) at least 260 adult Americans believe the overall state of
moral values is poor. Would you find this result unusual? Why?

Answers

The probability that exactly 250 of those surveyed feel the state of morals is poor is approximately 0.9918.

(To find the probability that exactly 250 of those surveyed feel the state of morals is poor, we can use the normal approximation to the binomial with mean np = 500 * 0.45 = 225 and standard deviation √(npq) = √(500 * 0.45 * 0.55) ≈ 10.42, where q = 1 - p.

Then, we can standardize the value of 250 using the formula z = (x - np) / √(npq), where x is the number of people who feel the state of morals is poor.

z = (250 - 225) / 10.42 ≈ 2.4

Using a standard normal table or calculator, we find that the probability of z being less than or equal to 2.4 is approximately 0.9918.

Therefore, the probability that exactly 250 of those surveyed feel the state of morals is poor is approximately 0.9918.

(b) To find the probability that no more than 220 of those surveyed feel the state of morals is poor, we can use the normal approximation to the binomial with mean np = 500 * 0.45 = 225 and standard deviation √(npq) = √(500 * 0.45 * 0.55) ≈ 10.42, where q = 1 - p.

Then, we can standardize the value of 220 using the formula z = (x - np) / √(npq), where x is the number of people who feel the state of morals is poor.

z = (220 - 225) / 10.42 ≈ -0.48

Using a standard normal table or calculator, we find that the probability of z being less than or equal to -0.48 is approximately 0.3146.

Therefore, the probability that no more than 220 of those surveyed feel the state of morals is poor is approximately 0.3146.

Is 5:10 and 15:30 equivalent

Answers

Yes, 5:10 and 15:30 are equivalent ratios because they simplify to the same ratio of 1:2.

Ratios represent the relationship between two or more quantities or values. When two ratios have the same simplified form, they are considered equivalent because they represent the same relationship between the quantities being compared.

In the given example, the ratios 5:10 and 15:30 can be simplified to the same ratio of 1:2. This means that both ratios represent the same relationship between the quantities being compared. Specifically, both ratios represent a comparison between two quantities where the second quantity is twice as large as the first quantity.

To simplify a ratio, we divide both the numerator and denominator by their greatest common factor (GCF). The GCF is the largest number that divides evenly into both the numerator and denominator. In this case, the GCF of 5 and 10 is 5, and the GCF of 15 and 30 is 15. Dividing both ratios by their respective GCFs results in a simplified ratio of 1:2 for both ratios.

Therefore, 5:10 and 15:30 are equivalent ratios because they represent the same relationship between quantities, and have the same simplified form.

Suppose on your 21st birthday you begin saving $500 quarterly into an account that pays 12% compounded quarterly. If you continue the savings until your 51st birthday (30 years), how much money will be in the account?

Answers

Answer:$386,711.70

Step-by-step explanation:

To solve the problem, we can use the formula for the future value of an annuity:

FV = PMT x [(1 + r/n)^(n*t) - 1] / (r/n)

where:

FV = future value

PMT = payment per period

r = annual interest rate

n = number of compounding periods per year

t = number of years

First, we need to find the number of compounding periods and the interest rate per quarter:

n = 4 (quarterly compounding)

r = 0.12 / 4 = 0.03 (3% quarterly interest rate)

Next, we can plug in the values:

PMT = $500

n = 4

r = 0.03

t = 30

FV = $500 x [(1 + 0.03/4)^(4*30) - 1] / (0.03/4)

FV = $500 x [(1 + 0.0075)^120 - 1] / 0.0075

FV = $500 x [6.3207 - 1] / 0.0075

FV = $500 x 773.4234

FV = $386,711.70

Therefore, if you save $500 quarterly into an account that pays 12% compounded quarterly from your 21st to your 51st birthday, you will have approximately $386,711.70 in the account.

In this case, we have:
P = $500
r = 0.12 (12% as a decimal)
n = 4 (since interest is compounded quarterly)
t = 30 (the number of years)

Plugging in the values, we get:

A = $500(1 + 0.12/4)^(4*30)
A = $500(1 + 0.03)^120
A = $500(1.03)^120
A = $500(15.5919)
A = $7,795.96

Therefore, after 30 years of quarterly savings at a 12% interest rate compounded quarterly, there will be approximately $7,795.96 in the account.

A scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt. She knows that Solution A is 70% salt and Solution B is 95% salt. She wants to obtain 120 ounces of a mixture that is 75% salt. How many ounces of each solution should she use?

Answers

The number of ounces in solution A= 16, and the number of ounces in the solution B = 104

let x be the number of ounces of solution A

let y be the number of ounces of solution B

x+y=120

Substitute the value of y,

y=120-x

Solution A is 70% salt and B is 95% salt,

then

0.7x+.95y=.75(120)

0.7x+.95y=90

multiply both sides of the equation by 100 to remove the decimal points,

70x+95y=900

70x+95(120-x)=900

70x+1140-95x=900

-15x=900-1140

15x=240

x=16

and y=120-16

y=104

The number of ounces in solution A= 16

and the number of ounces in solution B = 104

houses can be placed on the street?
1

Answers

The maximum number of homes that can be placed on the street is 11.

To calculate the number of houses that can be placed on the street

first we need to divide the total length of the street by the width of each home.

The length of the street is 345 feet and the width of each home is 30 feet. Therefore, the number of homes that can be placed on the street is:

345 feet / 30 feet per home = 11.5 homes

Since we cannot have a fraction of a home, we need to round down to the nearest whole number.

Therefore, the maximum number of homes that can be placed on the street is 11.

What does the distance calculation mean?

the algebraic equation known as the distance formula, which provides the distances between two locations as an expression of their coordinates. (see coordinate system). The distance formulas for locations in rectangular coordinates in two- and multidimensional Euclidean spaces are founded on the theorem known as Pythagorean.

To find how many miles John's house is from the grocery store, we need to add the distance from John's house to the office and the distance from the office to the grocery store.

Distance from John's house to the office = 1 and 2/3 miles

Distance from the office to the grocery store = 2/3 miles

Total distance from John's house to the grocery store = (1 and 2/3) + (2/3) = 2 miles

Therefore, John's house is 2 miles from the grocery store.

.

Q′S′¯¯¯¯¯¯¯¯¯¯
is parallel to A′H′¯¯¯¯¯¯¯¯¯¯¯
.

Answers

The statement "S′H′ is parallel to S′Q′" is true.

How to find the correct statement?

To find the image of the square after reflection across the x-axis, we need to flip each point of the square over the x-axis. The coordinates of the reflected points will have the same x-coordinate, but the y-coordinate will have the opposite sign.

The coordinates of the original square are:

S(−3,0)

H(2,0)

A(2,5)

Q(−3,5)

The coordinates of the reflected square are:

S′(−3,0)

H′(2,0)

A′(2,−5)

Q′(−3,−5)

Now, we can find the slopes of the sides of the reflected square to determine which sides are parallel.

S′H′¯¯¯¯¯¯¯¯¯¯¯: The slope of S′H′¯¯¯¯¯¯¯¯¯¯¯ is 0, since both points have the same y-coordinate. Therefore, S′H′¯¯¯¯¯¯¯¯¯¯¯ is parallel to the x-axis.

S′Q′¯¯¯¯¯¯¯¯¯¯: The slope of S′Q′¯¯¯¯¯¯¯¯¯¯ is 0, since both points have the same y-coordinate. Therefore, S′Q′¯¯¯¯¯¯¯¯¯¯ is also parallel to the x-axis.

H′A′¯¯¯¯¯¯¯¯¯¯¯: The slope of H′A′¯¯¯¯¯¯¯¯¯¯¯ is undefined, since the two points have the same x-coordinate. Therefore, H′A′¯¯¯¯¯¯¯¯¯¯¯ is parallel to the y-axis.

H′S′¯¯¯¯¯¯¯¯¯¯¯: The slope of H′S′¯¯¯¯¯¯¯¯¯¯¯ is also undefined, since the two points have the same x-coordinate. Therefore, H′S′¯¯¯¯¯¯¯¯¯¯¯ is parallel to the y-axis.

A′Q′¯¯¯¯¯¯¯¯¯¯: The slope of A′Q′¯¯¯¯¯¯¯¯¯¯ is 0, since both points have the same y-coordinate. Therefore, A′Q′¯¯¯¯¯¯¯¯¯¯ is parallel to the x-axis.

Q′S′¯¯¯¯¯¯¯¯¯¯: The slope of Q′S′¯¯¯¯¯¯¯¯¯¯ is 0, since both points have the same y-coordinate. Therefore, Q′S′¯¯¯¯¯¯¯¯¯¯ is also parallel to the x-axis.

Based on these calculations, we can see that S′H′¯¯¯¯¯¯¯¯¯¯¯ is parallel to S′Q′¯¯¯¯¯¯¯¯¯¯ (both are parallel to the x-axis). Therefore, the statement "S′H′¯¯¯¯¯¯¯¯¯¯¯ is parallel to S′Q′¯¯¯¯¯¯¯¯¯¯" is true.

B: 55 ft2
C: 225 ft2
D: 450 ft2

Answers

Total area of garden after adding rectangular piece will be 55 ft² i.e. B.

What exactly is a rectangle?

A rectangle is a two-dimensional geometric shape that is characterized by having four sides and four right angles. Opposite sides of a rectangle are parallel and equal in length, while opposite angles are equal. The area of a rectangle can be calculated by multiplying its length by its width, while its perimeter is the sum of the lengths of all its sides. Rectangles are commonly used in many fields, such as architecture, engineering, and mathematics.

Now,

The rectangle has a length of |-21 - (-23)| = 2 and a width of |7 - 12| = 5. Therefore, the area of the new rectangular piece is 2 x 5 = 10 square feet.

Adding this to the area of the existing garden gives a total area of 45 + 10 = 55 square feet.

Therefore, the answer is (B) 55 ft².
