ALL e 3 3. Team Formation HackerRank is organizing a chess tournament for its employees. There are n employees, having IDs 1, 2,.. n, where the th employee has rating denoted by rating[i]. Two employees can form a team if they have the same rating, and one employee can be in at most one team, There are q queries, each of the form (/, r). For each query, find the number of teams which can be formed considering employees with IDs [1, 1+1,.. r- 1, r]. All queries are independent of each other. Example: [[1,4], [3, 4]] Consider n = 4, rating = [2, 3, 4, 2], q= 2, queries • For the first query, all employees are considered. Employees with IDs 1 and 4 can be teamed as their ratings are the same. There are no other team formations possible. So, the number of teams is 1. • For the second query, employees 3 and 4 are considered, their ratings are [3, 4]. Since they are different, no teams can be formed. So, the number of teams is 0.

The volume of the solid obtained by rotating the region bounded by the curves y = 5[tex]x^5[/tex] and y = 5x about the x-axis is -(8π/21) cubic units.

We have,

To find the volume of the solid obtained by rotating the region bounded by the curves y = 5[tex]x^5[/tex] and y = 5x about the x-axis, we can use the method of cylindrical shells.

The region bounded by the curves is between x = 0 and x = 1.

Let's consider an infinitesimally thin strip of width dx at a distance x from the y-axis.

The height of this strip will be the difference between the two curves:

(5[tex]x^5[/tex]) - (5x).

The circumference of the shell at this distance x is 2πx (since we are rotating about the x-axis).

Therefore,

The volume of this infinitesimally thin shell is given by:

dV = (2πx) x [(5[tex]x^5[/tex]) - (5x)] x dx.

To find the total volume, we integrate this expression over the interval [0, 1]:

V = ∫(0 to 1) (2πx) x [(5[tex]x^5[/tex]) - (5x)] dx.

Simplifying the expression inside the integral:

V = 2π ∫(0 to 1) [(5[tex]x^6[/tex]) - (5x²] dx.

Integrating term by term:

V = 2π [([tex]x^7[/tex])/7 - (x³)/3] evaluated from 0 to 1.

Substituting the limits of integration:

V = 2π [(([tex]1^7[/tex])/7 - (1³)/3) - (([tex]0^7[/tex])/7 - (0³)/3)].

Simplifying:

V = 2π [(1/7 - 1/3) - (0 - 0)].

V = 2π [(3 - 7)/21].

V = 2π (-4/21).

V = -(8π/21).

Therefore,

The volume of the solid obtained by rotating the region bounded by the curves y = 5[tex]x^5[/tex] and y = 5x about the x-axis is -(8π/21) cubic units.

The amount Casey invested in the certificate of deposit is; $60,000.

An equation is an expression that shows the relationship between two or more numbers and variables.

Assume that

0.01c -  0.02s = $250---equation 1

c + s = $10,000 ------ equation 2

Where: c = amount invested in the certificate of deposit

s = amount invested in the savings account

Now Multiply equation 2 by 0.01:

0.01c + 0.01s = 100 equation 3

Subtract equation 3 from equation 1:

0.01s = 100

Divide both sides of the equation by 0.01:

s = 100 / 0.01

s = 10,000

Substitute for s in equation 2:

c + 10,000 = 70,000

c = 70,000 - 10,000

c = 60,000

The solution of each part of the question is given below:

a. Let C be the event that a person smokes cigars, and let S be the event that a person smokes cigarettes. The percentage of Americans who smoke either cigars, cigarettes, or both can be calculated as P(C U S), where U represents the union of two events. From the given information, P(C) = 15% and P(S) = 35%. The probability that a person smokes both cigars and cigarettes is 7%, so P(C ∩ S) = 7%.

P(C U S) = P(C) + P(S) - P(C ∩ S)

P(C U S) = 15% + 35% - 7% = 43%

So, 43% of Americans smoke either cigars, cigarettes, or both.

b. The percentage of Americans who smoke neither cigars nor cigarettes can be calculated as P(C' ∩ S'), where C' represents the complement of event C (not smoking cigars) and S' represents the complement of event S (not smoking cigarettes).

P(C' ∩ S') = 100% - P(C U S)

P(C' ∩ S') = 100% - 43% = 57%

So, 57% of Americans smoke neither cigars nor cigarettes.

c. The percentage of Americans who smoke cigars but not cigarettes can be calculated as P(C ∩ S').

P(C ∩ S') = P(C) - P(C ∩ S)

P(C ∩ S') = 15% - 7% = 8%

So, 8% of Americans smoke cigars but not cigarettes.

d. The conditional probability that a person smokes cigarettes given that he smokes cigars can be calculated as P(S | C), where S represents the event that a person smokes cigarettes and C represents the event that a person smokes cigars.

P(S | C) = P(S ∩ C) / P(C)

P(S | C) = 7% / 15% = 0.47

So, the conditional probability that a randomly selected person smokes cigarettes given that he smokes cigars is 0.47, or 47%.

The angle included by these two sides is (c^2 - 74) / (-70).

What is triangle ?

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted triangle ABC.

The area of a triangle can be found using the formula:

Area = (1/2) * b * h,

where b is the length of the base and h is the height of the triangle.

Since two of the sides have lengths 5 in and 7 in, we can assume that they are the base and the height of the triangle, respectively. Setting b = 5 in and h = 7 in, we can find the area:

Area = (1/2) * 5 in * 7 in = (1/2) * 35 in^2 = 16 in^2.

This means that the height of the triangle is 7 in and the base is 5 in. To find the angle included by these two sides, we can use the Law of Cosines:

c^2 = a^2 + b^2 - 2ab * cos(C),

where a and b are the lengths of the sides and C is the angle included by these two sides.

Since a = 5 in and b = 7 in, we can find the angle C:

c^2 = a^2 + b^2 - 2ab * cos(C)

c^2 = 5^2 + 7^2 - 2 * 5 * 7 * cos(C)

c^2 = 25 + 49 - 70 * cos(C)

c^2 = 74 - 70 * cos(C)

The total weight of each bag follows an approximately normal distribution with a mean of 16.15 ounces and a standard deviation of 0.12 ounces.

Mean (μ) = 16.15

Standard deviation, (σ) = 0.12

n = 6

Buckley Farms decides to increase the mean weight of each bag of chips so that only 5%(0.05) of the bags have weights that are less than 16 ounces. So

P(X > x) = 0.05

P[(X - μ)/(σ/√n) > (x - μ)/(σ/√n)] = 0.05

1 - P(Z ≤ z) = 0.05

Subtract 1 on both side , we get

P(Z ≤ z) = 0.95

z = 1.96

(x' - μ)/(σ/√n) = 1.645

Now putting the value

(x' - 16.15)/(0.15/√6) = 1.645

(x' - 16.15)/(0.15/2.45) = 1.645

(x' - 16.15)/(0.0612) = 1.645

Multiply by 0.0612 on both side, we get

A bisector exists for each angle. Additionally, it is the symmetry line that connects an angle's two arms, triangle  whose construction facilitates the creation of smaller angles.

Here,

A 30° angle, for example, might be called for. A 60° angle can be made, and it can then be divided, to accomplish this.

The concept of an angle bisector is used to construct angles such as 90 degrees, 45 degrees, 15 degrees, and others.

Examples :

What is each angle's measurement if an angle bisector divides an angle of 80 degrees?

The answer is that 80 degrees is the measure of an angle.

It is common knowledge that the angle is divided into two equal pieces by the angle bisector.

Consequently, 80 degrees is divided into two equal portions, let's call x.

Hence,

x + x = 80°

2x = 80°

x = 80°/2

x = 40°.

The second option is ineffective since it would result in A' being positioned at (-5, 2) after translation A 3 up and 1 left (5, -2).

The third option: spinning A in a clockwise direction 90 degrees places it at (-1, 4), then reflecting it across the y-axis places it at (1, 4).

In the fourth option, A is rotated 90 degrees counterclockwise, putting it at (1, -4), and it is reflected across the x-axis, putting it at (1, 4).

The fifth option is to rotate A 180 degrees, which positions it at (-3, -4), after translating 3 down & 1 right (3, 4). B(-5, -5) (-5, -5)  Translated results in (-4, -8), and rotated results in (4, 8). Translation of C(-3, -4) results in (-2, -7), and rotation results in (2, 7).

Approximately 86.5% of customers will be served in less than 10 minutes and only 13.5% of customers will take more than 10 minutes to check out.

To find the proportion of customers who take more than 10 minutes to check out, we need to calculate the cumulative distribution function (CDF) of an exponential distribution at 10 minutes and subtract it from 1. The CDF for an exponential distribution with mean (lambda) 5 minutes is given by:

CDF = 1 - e^(- λ * x)

Plugging in λ = 0.2 (1/mean) and x = 10, we get:

CDF = 1 - e^(-0.2 * 10) = 1 - e^(-2) = 1 - 0.135 = 0.865
