There are approximately 3263 total albums and CDs are in the collection.

Percentage is defined as part of a whole expressed in hundredths or out of 100. It is usually written with the symbol "%".

let 'x' be the total albums and CDs in the collection

If the music fan has 2000 CDs, which comprise 61.3% of the total collection, then 61.3% of x is equal to 2000.

2000 albums and CDs = 61.3% of the total albums and CDs in the collection

2000 = 61.3% of x

2000 = 0.613x

Solving for x,

x = 3262.6

the total albums and CDs in the collection ≅ 3263

Therefore, the the total albums and CDs in the collection is approximately 3263.

Answer:

y + 4 = - [tex]\frac{5}{6}[/tex] (x - 8)

Step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

here m = - [tex]\frac{5}{6}[/tex] and (a, b ) = (8, - 4 ), that is a = 8, b = - 4 , then

y - (- 4) = - [tex]\frac{5}{6}[/tex] (x - 8) , that is

y + 4 = - [tex]\frac{5}{6}[/tex] (x - 8)

The precentile for a student in the class who studies 8 hours a week is 5.74%.

To find the percentile for a student who studies 8 hours a week, we need to first standardize the student's study time by subtracting the mean study time and dividing it by the standard deviation of study time. This will give us the student's z-score. We can then look up the student's z-score in a standard normal table to find the percentile.

The student's z-score is (8 - 9.92) / 4.54 = -1.67.

Looking up -1.67 in a standard normal table, we find that the percentile is about 5.74%. This means that about 5.74% of the students in the class studied for less than 8 hours per week.

As per the given standard deviation, the percentile for a student in the class who studies 8 hours a week is 50.80%

The term standard deviation in math is known as a measure which shows how much variation from the mean exists.

Here we have given that in one statistics course students reported studying an average of 9.92 hours a week with a standard deviation of 4.54.

Through this details, we have identified that the value of the following are given that,

=> weekly study time = 10 hours

=> average study time = 9.92 hours

=> standard deviation = 4.54 hours

Then the formula to calculate the Test statistic is written as

=> z = (weekly study time - average study time)/standard deviation

Apply the values on it, then we get

=> z = (10 - 9.92)/4.54

=> z = 0.08/4.54 = 0.02

While we take the value of z table, then we get the Cumulative area of the test statistic is 0.5080.

And the percentile is calculated by multiply the value by 100 as,

=> 0.5080 × 100 = 50.80

The popular vote, which determines the winner of a presidential election, is simply the total number of voters from all 50 states. The popular vote is deemed to have been won by the candidate with the most votes cast nationally.

Every four years on the first Tuesday in November, the US holds its presidential election. The candidate must have at least 35 years of age, have been born in the US, and have resided in the US for the previous 14 years in order to be eligible.

Traditionally, candidates announce their intention to run for president one year prior to the election. Since there is no national body that organises elections, local authorities organise them with the aid of tens of thousands of administrators.

On January 20, the United States Capitol in Washington, D.C., will host Inauguration Day. The Vice President is sworn in first, then the President.

The maximum number of full pizzas she can make if Avery had 7 pounds of cheese available, and she needs 3/5 pounds of cheese to make each pizza, is 11.

When dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers. For instance, 4 2 = 2. As a multiplication fact, this can be expressed as 2 + 2 = 4.

Given:

Avery had 7 pounds of cheese available, and she needs 3/5 pound of cheese to make each pizza,

Calculate the number of pizzas she can make as shown below,

The number of pizzas = total cheese/cheese required to make one pizza

The number of pizzas = 7 / 3/5

The number of pizzas = 7 × 5 / 3

The number of pizzas = 35 / 3

Thus, the total number of pizzas she can make is 11 and 2 / 3.

By using the bubble sort algorithm, a total of 9 passes/scans will be there.

When an array or list of items has to be rearranged, a sorting algorithm is used to compare the elements and sort the elements in the array or list. In each data structure, the new order of the items is determined using the comparison operator.

The simplest sorting method is called Bubble Sort, and it involves periodically exchanging nearby components if they are arranged incorrectly. Since the average and worst-case time complexity of this approach is relatively high, it is not appropriate for huge data sets.

According to the question, we have

Total number of elements we are having, i.e., n = 10

The total number of passes = n-1 = 10 - 1 = 9

Answer:

sinθ = -3/5, Quadrant IV (Option B)

Step-by-step explanation:

Let's first find the sine

cosθ = adj./hyp.

Pythagorean theorem (in terms of right triangle trig) = (opp)^2 + (adj)^2 = (hyp)^2

Plug in the adjacent and hypotenuse

(opp.)^2 + 16 = 25

solve for the opposite side

opp. = 3

To find the quadrant, recall the sin <0, so the sin has to be negative.

So, your sine value is -3/5.

Sine is negative at Quadrants III and IV, so eliminate C and D.

Since your cosine value is positive, it is at Quadrant IV (Cosine is positive at the first and fourth quadrants.)

Therefore, Option B is correct.

Answer:

[tex]P(x)=x^5+10x^4+75x^3+10x^2+74x[/tex]

Step-by-step explanation:

Given information:

For any complex number  [tex]z=a+bi[/tex], the complex conjugate of the number is defined as  [tex]z^*=a-bi[/tex].  

If f(z) is a polynomial with real coefficients, and z₁ is a root of f(z)=0, then its complex conjugate z₁* is also a root of f(z)=0.

Therefore, if P(x) is a polynomial, and i is a root of f(x)=0, then its complex conjugate -i is also a root of P(x)=0.

Similarly, if P(x) is a polynomial, and -5+7i is a root of f(x)=0, then its complex conjugate -5-7i is also a root of P(x)=0.

Therefore, the polynomial in factored form is:

[tex]P(x)=x(x-i)(x-(-i))(x-(-5+7i))(x-(-5-7i))[/tex]

[tex]P(x)=x(x-i)(x+i)(x+5-7i)(x+5+7i)[/tex]

Expand the polynomial:

[tex]P(x)=x(x^2-i^2)(x^2+10x+25-49i^2)[/tex]

[tex]P(x)=x(x^2-(-1))(x^2+10x+25-49(-1))[/tex]

[tex]P(x)=x(x^2+1)(x^2+10x+74)[/tex]

[tex]P(x)=x(x^4+10x^3+75x^2+10x+74)[/tex]
