The required percent decrease in the price of the skateboard is 40%.

What is the percentage?

A % is a number that indicates how many out of 100 it is, and it can also be expressed as a decimal or a fraction. Put the percentage value in the numerator and 100 in the denominator to convert a percentage to a fraction.

Here, we have

Original price = $84.50

sale price = $50.70

Percent decrease = 84.50-50.70/84.50 × 100 = 40%

Hence, the required percent decrease in the price of the skateboard is 40%.

The probability that the committee includes all 3 women is 0.00018

In this question, we have been given there are 97 men and 3 women in an organization.

A simple random sample of 5 people is taken to form a committee.

We need to find  the probability that the committee includes all 3 women.

Total number of people in the organization: 97 + 3 = 100

Usinng combination formula the possible number of 5 people committee:

100C5

= 100! / 5!(100 - 5)!

= 75287520

The number of outcomes for the committee includes all 3 women would be:

5C3 = (97C2)*3

       = 13968

So, the probability that the committee includes all 3 women would be,

P = 13968 / 75287520

P = 0.00018

Answer:

22 divided by 2 is 11

Step-by-step explanation:

The missing factor for A in the model is 3/4

From the question, we have the following parameters that can be used in our computation:

Length of column A = 4

Shaded region in column A = 3

This means that

The missing factor = Shaded region/Length of column A

Substitute the known values in the above equation, so, we have the following representation

The missing factor, A = 3/4

Here, we have

Length of column B = 5

Shaded region in column B = 1

This means that

The missing factor = Shaded region/Length of column B

Substitute the known values in the above equation, so, we have the following representation

The missing factor, B = 1/5

In (a) and (b), we have

The missing factor, A = 3/4

The missing factor, B = 1/5

So, we have

Pair = 3/4 * 1/5

Evaluate

Pair = 3/20

If the model is true, there would be around 1689 students sick during the 12th week of classes.

The number of students getting sick was growing exponentially with a growth factor of ‘1.6.

Week 1 : (6)

Week 2 : (10)

Week 3 : (15).

To find the number of students sick on the 12th week of school, we can use the formula for exponential growth:

y = a bˣ

Where:

y is the number of students sick on the x th week

a is the number of students sick on the first week (6 in this case)

b is the growth factor (1.6 in this case)

x is the number of weeks that have passed (12 in this case)

Plugging in the values, we get:

y = 6 · 1.6¹²

Solving for y, we get:

y = 6 · 281.47

y = 1688.8 ≈ 1689

Therefore, there would be approximately 1689 students sick on the 12th week of school if the model is correct.

Business mathematics is the branch of mathematics utilized by businesses to track and coordinate their operations. Accounting, inventory management, marketing, sales forecasting, and financial analysis are all areas where commercial businesses apply mathematics.

According to Question:

let the the subtotal on the bill was xx dollars

A tax of 8% is added on bill then Bill becomes xx + 8% of xx

The of 8% on bill = (108/100)xx

Now the Final bill = xx + (108/100)xx

                    = (208/100)xx

Hailey decides to leave a tip of 24% on the entire bill (including the tax)

So the Total Amount = (208/100)xx + 24% of Final bills

⇒

24% of (208/100)xx = (208/100)(124/100)xx

The Total amount = (208/100)xx +(208/100)(124/100)xx

Let the Amount be A

hence, expression in terms of xx that represents the total amount that Hailey paid is A = (208/100)xx +(208/100)(124/100)xx

⇒ A = (52/25)xx +(52/25)(31/25)xx

⇒ 625A = 625((52/25)xx +(52/25)(31/25)xx)

⇒ 625A = 1300xx + 1612xx

⇒ 625A = 2912xx

The lengths of the sides of the triangle are 5, 12, and 13.

So the correct option is the last one.

Remember that if we have two points (x₁, y₁) and (x₂, y₂), the distance between these two points is given by the formula:

d = √( (x₁ - x₂)² + (y₁ - y₂)²)

Here we know that the vertices of our triangle are the points:

(0, 0), (5, 0), (5, 12)

And we want to find the lengths of the sides.

We can get the length of the first side using the points  (0, 0), (5, 0)

d₁ = √( (0 - 5)² + (0 - 0)²) = 5

The length of the second side is: (5, 0), (5, 12).

d₂ = √( (5 - 5)² + (0 - 12)²) = 12

The length of the third is side is given by the points (5, 12) and (0, 0)

d₃ = √( (5 - 0)² + (12 - 12)²)

d₃ = √(25 + 144) = 13

The difference between Z₁ and Z₂ is -10 + 0i.

Z₁ - Z₂ locates on the real axis, this is solved using the concept of complex numbers.

Option b is correct.

Real numbers and imaginary numbers combine to form complex numbers, which have two components. Complex numbers serve as the foundation for more complex arithmetic, including algebra.

Complex numbers are those that are represented as a+ib, where a and b are actual numbers and i is an imaginary number termed a "iota." i  has the value (√-1).

From the graph we can know:

Z₁ (-5,2) = -5 + 2i

Z₂ (5,2) = 5 + 2i

The difference between Z₁ and Z₂ is Z₁ - Z₂

So, Z₁ - Z₂ = (-5 + 2i) - (5 + 2i)

Z₁ - Z₂ = - 10 + 0i

A 12-foot ladder is resting against a wall and makes an angle of 52 degrees with the ground, the height to which the ladder will reach the wall is 9.456 foot.

Height, altitude, and elevation all refer to the vertical distance between something's top and bottom or its base and something above it. Height is a term used to describe everything that may be measured vertically, high or low.

From the lowest to the highest point to the lowest point, it calculates the vertical distance. In general, it refers to a coordinate geometry object's measurement along the y-axis.

let, h = height of ladder

Given that,

length of ladder = 12 ft

angle with the ground = 52°

As we know,

sinθ = h/12

or, sin (52°) = h/12

An isosceles triangular prism, its surface area becomes: 568 feet²

The faces of a polyhedron called an isosceles triangular prism are made up of polygons. It has six edges, five faces, and five vertices. Isosceles triangles make up the two portions at the base that face each other and rectangles make up the vertical faces of the five faces.

where the isosceles triangle's base has equal sides measured in "a" units, each triangle's base measured in "b" units, the triangle's height measured in "h" units, and the length of the congruent rectangles measured in "l" units.

The surface area of an isosceles triangular prism is:

Surface area = (b × h) + (2× l × a) + (l × b)

here, b = the base of each of the triangle = 16 feet

h = the height of the triangle = 18 feet

l = length of the congruent rectangles = 10 feet

a = isosceles triangle in the base have the equal sides be "a" units = 6 feet

Now, Surface area = (16 × 18) + (2 × 10 × 6) + (10 × 16)

The approximate mean and standard deviation of the number of chips meeting specifications are: μ = 16.2; σ = 1.273

In this question, we have been given a factory makes silicon chips for use in computers. it is known that about 90% of the chips meet specifications. every hour a sample of 18 chips is selected at random for testing and the number of chips that meet specifications is recorded.

we need to find  the approximate mean and standard deviation of the number of chips meeting specifications

Since 90% meet specifications we can say p = 0.9

So, q = 1 - p

q = 1 - 0.9

q = 0.1

here,  a sample size is n = 18

So, the mean would be,

μ = np

μ = 18 * 0.9

μ = 16.2

And the standard deviation would be,

σ = √npq

σ = √(18 * 0.9 * 0.1)

σ = 1.273

Therefore, the mean (μ) = 16.2 and the standard deviation (σ) = 1.273

It will take about 18 million years for Los Angles to be located next to san Francisco.

The distance traveled is 630km (380 miles), and the net distance moves is 36mm per year.

We can use this formula to determine the answer :

Time = distance/rate

630 km = 630,000 m = 630, 000,000 mm

Time = 630,000,000 mm/ 36mm/year = 17,500,000 year

We could also put these dimensional relationship together as follows and then cancel units that occur in both the numerator and the denominator .

We are left with an answer in number of years:

630 km × [tex]\frac{1000m}{1km 1m}[/tex]  × [tex]\frac{1000mm 1 year}{36mm}[/tex]  = 17,500,000 year

An equation of a curve that has a point on it that is equally spaced from a fixed point and a fixed line is referred to as a parabola. The parabola's fixed line and fixed point are together referred to as the DirectX and focus, respectively.

Given:

The vertex = (-3, 4) and the point = (2, 8)

Write the equation using the standard form given below,

[tex]y = a (x - h)^2 + k[/tex]
