The percent markdown rounded to the nearest percent is 13%.

What is percent markdown?

Markdown represents the difference between the original or full price of an item and the current price that's reduced. It's typically expressed as a percentage.

Equation:

To find the percent markdown, we first need to calculate the amount of markdown, which is the difference between the original price and the sale price:

Markdown = $175.90 - $153.77 = $22.13

Next, we need to find the percent markdown by dividing the markdown by the original price and multiplying by 100:

Percent Markdown = (Markdown / Original Price) x 100

Percent Markdown = ($22.13 / $175.90) x 100

Percent Markdown = 0.1258 x 100

Percent Markdown = 12.58%

Rounded to the nearest percent, the percent markdown is 13%.

There is a 1.8% probability that a customer will buy clothes, shoes, AND jewelry.

This statement is false. The probability that a customer buys clothes, shoes, and jewelry is not given

How to solve the problem ?

Let's denote the event that a customer buys clothes by C, the event that a customer buys jewelry by J, and the event that a customer buys shoes by S. We are given that the probabilities of these events are independent. Therefore, the probability of a customer buying clothes and shoes, denoted by C and S, is simply the product of the probabilities of buying clothes and buying shoes, which is 0.6 × 0.3 = 0.18. Similarly, the probability of a customer not buying shoes and buying jewelry, denoted by S' and J, is simply the product of the probabilities of not buying shoes and buying jewelry, which is 0.7 × 0.1 = 0.07.

Using these probabilities, we can now check the statements:

There is a 15% probability that a customer buys NO clothes, NO shoes, and NO jewelry.

This statement is true. The probability that a customer buys none of these items is simply the complement of the probability that the customer buys at least one of them. Using the inclusion-exclusion principle, we have:

P(C ∪ J ∪ S) = P(C) + P(J) + P(S) - P(C ∩ J) - P(C ∩ S) - P(J ∩ S) + P(C ∩ J ∩ S)

P(C ∪ J ∪ S) = 0.6 + 0.1 + 0.3 - 0 - 0.18 - 0 + P(C ∩ J ∩ S)

P(C ∪ J ∪ S) = 0.52 + P(C ∩ J ∩ S)

Therefore, the probability that a customer buys none of these items is:

P((C ∪ J ∪ S)') = 1 - P(C ∪ J ∪ S) = 0.48 - P(C ∩ J ∩ S)

We are not given the value of P(C ∩ J ∩ S), but we know that it cannot be negative. Therefore, the maximum value of P((C ∪ J ∪ S)') is 0.48, which corresponds to the case where P(C ∩ J ∩ S) = 0. In this case, the probability that a customer buys none of these items is 0.48, which is 15% of 1.

There is a 70% probability that a customer does NOT buy shoes.

This statement is true. The probability that a customer does not buy shoes is simply the complement of the probability that the customer buys shoes, which is 0.3. Therefore, the probability that a customer does not buy shoes is 1 - 0.3 = 0.7, which is 70% of 1.

There is an 8.5% chance that a customer buys jewelry.

This statement is false. The probability that a customer buys jewelry is not given directly. However, we can use the information about the probability of not buying shoes and buying jewelry to find it. We have:

P(S' ∩ J) = P(S') × P(J) = 0.7 × 0.1 = 0.07

Therefore, the probability that a customer buys jewelry is:

P(J) = P(S' ∩ J) + P(S ∩ J) = 0.07 + 0 = 0.07

This is 7% of 1, not 8.5%.

There is a 1.8% probability that a customer will buy clothes, shoes, AND jewelry.

This statement is false. The probability that a customer buys clothes, shoes, and jewelry is not given

Required length of HF, angle H, angle F are 12.05 unit, 44.2°, 80.5° respectively.

How to find the length of the third side of a triangle when length of two sides are already given?

To find the length of the third side, HF, we can use the Law of Cosines, which states that:

c² = a² + b² - 2ab cos(C)

where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

In this case, we have:

HF² = HG² + GF² - 2HG × GF × cos(HGF)

HF² = 7² + 13² - 2 × 7 × 13 × cos(136°)

HF² = 49 + 169 - 182cos(136°)

HF² ≈ 145.35

Taking the square root of both sides,

HF ≈ 12.05

So the length of the third side, HF, is approximately 12.05 units.

To find the angles, we can use the Law of Sines, which states that,

a/sin(A) = b/sin(B) = c/sin(C)

where a, b, and c are the lengths of the sides opposite angles A, B, and C, respectively.

In this case, we know the lengths of HG, GF, and HF, so we can find the angles H and F,

sin(H) / 7 = sin(136°) / 12.05

sin(H) ≈ 0.689

H ≈ 44.2°

sin(F) / 13 = sin(136°) / 12.05

sin(F) ≈ 0.992

F ≈ 80.5°

Therefore, the length of HF is approximately 12.05 units, the angle H is approximately 44.2°, and the angle F is approximately 80.5°.

What is probability?

In playing cards, it can be used to predict the likelihood of a certain outcome or to make decisions based on the probability of certain events occurring.

(a) The probability of the questions being history, literature, and science in that order is 5/18 x 6/17 x 7/16, which is 0.04.

(b) The probability of all three questions being literature questions is 6/18 x 5/17 x 4/16, which is 0.024.

Answers

We know that z varies directly as √√x and inversely as y, which can be written as:

z = k(√√x)/y

where k is the constant of proportionality.

To find the value of k, we can use the values given when x = 25 and y = 7:

179 = k(√√25)/7

179 = k(5/7)

k = (179*7)/5

k = 250.6

Now we can use this value of k to find z when x = 64 and y = 4:

z = 250.6(√√64)/4

z = 250.6(2)/4

z = 125.3

Therefore, z ≈ 125.3 when x = 64 and y = 4.

Find the value of each variable in the parallelogram. Round your answers to the nearest tenth, if necessary. G a = (46) K (3a +19) b H 56°​

The value of every variable in the parallelogram is: a = 9 HK = 27.0 GK = 46 G = 63.5°

What do you mean by Parallelogram ?

A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal.These shapes include squares, rectangles, rhombuses, and rhomboids. All of these shapes have four sides, four corners, and four angles

We know that sides of a parallelogram are parallel and congruent, as opposite angle

According to question  that GA equals HK, as:

46 is equal to 3a plus 19 When we subtract 19 from both sides, we get:

27 x 3a is the result of dividing both sides by 3:

we know that opposite angles in a parallelogram are congruent, we can use a = 9. Since angle H is 56 degrees, angle K must also be 56 degrees. The length of side HK can be determined using the Law of Cosines:

HK2 = GA2 + GK2 - 2(GA)(GK)cos(H) When we substitute the values we are familiar with, we obtain:

After solving the equation we obtain: HK2 = 462 + (3a + 19)2 - 2(46)(3a + 19)cos(56°).

HK2 = 2112 + 9a2 + 342a - 2764cos(56°) HK2 = 2112 + 9(9)2 + 342(9) - 2764cos(56°) HK2  732.4 By taking the square root of both sides, we obtain the following results:

∵ GA = 46, we can use the parallelogram's opposite sides being congruent to determine the length of side GK: HK  27.0

Then, we can use the Law of Cosines to determine the angle G's measurement:

cos(G) = (HK2 + GA2 - GK2) / (2(HK)(GA)) Using the values we are familiar with, we get,

cos(G) = (27.02 + 462 - 462) / (2(27.0)(46)) cos(G)  0.465 Using the inverse cosine, we get the following:

G ≈ 63.5°

Suppose he got dilates the rectangle shown below with the center of dilation at 0,0 and a scale factor of 2, and then translates the figure 1 unit to the left. What will be the coordinates of the vertices of the similar figure that results

Answers

The vertices of the similar figure that results from the dilation and translation will be A'' = (2a - 1, 2b), B'' = (2c - 1, 2b), C'' = (2c - 1, 2d), and D'' = (2a - 1, 2d).

Assume that the rectangle's four vertices are A, B, C, and D, with the corresponding coordinates being (a, b), (c, b), (c, d), and (a, d).

First, enlarge the rectangle.

We must multiply the coordinates of each vertex by the scale factor of two in order to enlarge the rectangle. We can apply the following formulas because the centre of dilation is at (0, 0):

Old x-coordinate + 2 equals the new x-coordinate

Old y-coordinate + 2 times the new y-coordinate

Therefore, following dilation, the new coordinates for the vertices will be: A' = (2a, 2b)

B' = (2c, 2b)

C' = (2c, 2d)

D' = (2a, 2d)

Translate the Figure in Step 2

The x-coordinate of each vertex must be reduced by one in order to translate the figure one unit to the left. Therefore, following translation, the vertices' new coordinates will be: A' = (2a - 1, 2b)

B'' = (2c - 1, 2b)

C'' = (2c - 1, 2d)

D'' = (2a - 1, 2d)

As a result, A'' = (2a - 1, 2b), B'' = (2c - 1, 2b), C'' = (2c - 1, 2d), and D'' = (2c - 1, 2d) will be the vertices of the similar figure that comes from the dilation and translation. (2a - 1, 2d).

Option 2: $50 initial investment with an average annual growth rate of 8% starting at age 20

Option 3: $100 initial investment with an average annual growth rate of 7% starting at age 25 ​

Answers

Based on these calculations, Option 3 yields the highest future value at age 35.

How to solve

To compare the investment options at different ages, we can use the future value formula:

FV = PV * (1 + r)^t

where:

FV = future value of the investment

PV = present value or initial investment

r = annual growth rate (as a decimal)

t = number of years the investment grows

Here are the general equations for each option:

Option 1: FV1 = 50 * (1 + 0.09)^(t - 10)Option 2: FV2 = 50 * (1 + 0.08)^tOption 3: FV3 = 100 * (1 + 0.07)^(t - 5)

To compare the options at ages 20, 25, 30, and 35, calculate the future value for each option at those ages by plugging in the corresponding value of t.

Age 20:

FV1 = N/A (Option 1 hasn't started yet)

FV2 = 50 * (1 + 0.08)^0 = $50

FV3 = N/A (Option 3 hasn't started yet)

Age 25:

FV1 = N/A (Option 1 hasn't started yet)

FV2 = 50 * (1 + 0.08)^5 ≈ $73.86

Write as a product. 1 -25x^2 +10xy-y^2

Answers

The expression 1 -25x² +10xy-y² in product form is (1-5x-y)(1+5x-y).

What is expression?

In mathematics, an expression is a combination of numbers, variables, and mathematical operations, such as addition, subtraction, multiplication, division, and exponentiation. Expressions can be simple, such as a single number or variable, or complex, involving multiple operations and variables. Expressions are used in a variety of mathematical contexts, including algebra, calculus, and geometry. They can be evaluated to obtain a numerical value, simplified by combining like terms or using algebraic identities, or used to represent mathematical relationships and patterns.

Here,

The given expression can be written as a product of two binomials as follows:

(1-5x-y)(1+5x-y)

Expanding this product gives:

1(1) + 5x(1) - y(1) - 5x(1) - 25x² + 5xy + y(1) - y(5x) - y²

Simplifying this expression gives:

1 - 25x² + 10xy - y²

Sneeze: According to a study done by Nick Wilson of Otago University Wellington, the probability a
randomly selected individual will not cover his or her mouth when sneezing is 0.267. Suppose you sit on
a bench in a mall and observe 300 randomly selected individuals’ habits as they sneeze.
Task 1: What is and what is ?
Task 2: What are the mean and standard deviation?
Task 3: What are the conditions that must be met to use the normal approximation to the binomial
distribution? Are they met?

Answers

Thus, the mean and standard deviation for the randomly selected individuals is found as: mean = 80.1 and standard derivation = 7.66.

Explain about the standard deviation:

The standard deviation is a measurement of how widely spaced out a set of data is from the mean. The bigger the dispersion or variability, the higher the standard deviation and the greater the magnitude of the value's divergence from its mean. It represents the absolute variability of a distribution.

Given data:

Number of population n = 300

probability p = 0.267

Mean is given as np:

np = 300*0.267

np = 80.1

standard derivation: √np(1 - p)

√np(1 - p) =  √80.1(1 - 0.267)

√np(1 - p) =  √58.7133

√np(1 - p) =  7.66

Thus, the mean and standard deviation for the randomly selected individuals is found as: mean = 80.1 and standard derivation = 7.66.

Complete the square to solve the quadratic below. 1=2x^2+7x

Answers

the solutions to the quadratic equation 1 = 2x^2 + 7x are:

[tex]x= \frac{(-7+\sqrt{51} )}{4}[/tex] and [tex]x= \frac{(-7-\sqrt{51})}{4}[/tex]

ToToToToToToToToToToToToToToToToToToToToToToToToToToToToToToToTo solve this quadratic equation by completing the square, we need to rewrite the equation in the form of (x + p)^2 + q = 0, where p and q are constants. This will allow us to solve for x.

First, we can factor out the coefficient of the x^2 term, which is 2:

[tex]2x^2 + 7x - 1 = 0[/tex]

Next, we can isolate the x^2 and x terms on one side of the equation by subtracting 1 from both sides:

[tex]2x^2 + 7x = 1[/tex]

Now, we need to add and subtract a constant term inside the parentheses to create a perfect square trinomial. To determine this constant term, we take half of the coefficient of the x term (which is 7/2) and square it:

[tex](\frac{7}{2} )^{2} = \frac{49}{4}[/tex]

So we add and subtract 49/4 inside the parentheses:

[tex]2x^2 + 7x + \frac{49}{4} - \frac{49}{4} = 1[/tex]

We can simplify the left side by factoring the perfect square trinomial:

[tex]2(x + \frac{7}{4} )^2 - \frac{51}{8} = 0[/tex]

Now, we can solve for x by isolating the perfect square term and taking the square root of both sides:

[tex]2(x + \frac{7}{4} )^2 = \frac{51}{8}[/tex]

[tex](x + \frac{7}{4} )^2 = \frac{51}{16}[/tex]

[tex]x + \frac{7}{4}=±\sqrt{\frac{51}{16} }[/tex]

[tex]x = -\frac{7}{4} ± \sqrt{\frac{51}{16} } /2[/tex]

Simplifying this expression, we get:

[tex]x = (-7 ±\sqrt{51} )/4[/tex]

Therefore, the solutions to the quadratic equation 1 = 2x^2 + 7x are:

[tex]x = (-7 + \sqrt{51} )/4 and x = (-7 -\sqrt{51} )/4.[/tex]

Janct was driving home from work at a speed of 40 mph. Realizing she forgot her documents as she arrived home, she then drove back to work at a speed of 60 mph. What is her average speed for the entire trip?
A. 48 mph
B.49 mph
C. 50 mph
D. 52 mph

Answers

Answer: 50 mph

Step-by-step explanation:  

we can use the formula for average speed when dealing with different speeds in two segments:

average speed = 2 * (speed1 * speed2) / (speed1 + speed2)

In this case,
speed1 = 40 mph (driving home)
speed2 = 60 mph (driving back to work)

average speed = 2 * (40 * 60) / (40 + 60)
average speed = 2 * (2400) / (100)
average speed = 4800 / 100
average speed = 48 mph

So, Janet's average speed for the entire trip is 48 mph (Option A).
