Tre has to pay $180 to book the recording studio plus $30 per hour of recording time. The function c(h)=30h+180 relates the total cost, c(h) of the recording session (in dollars) to the number of hours, (h) needed to record the tracks.

Answers

Answer:

1. $3302. 11.5 hours

Step-by-step explanation:

Continuation of the question:

1. Find c (5) and interpret your solution in the context of the problem 2. Find the value of h when c() = 525 and interpret your solution in the context of the problem

Solution

c(h) = 30h + 180

1 ...............................................

c(5) = 30*5 + 180 = $330

2 ...............................................

525 = 30h + 18030h = 525 - 18030h = 345h = 345/30 h = 11.5 hours

Create a 5th degree trinomial that has a constant term of 3.

Answers

Answer:

[tex]2x^5+3x^2+3[/tex] is a trinomial having with:

three terms degree 5 and The constant term '3'

Step-by-step explanation:

Considering the trinomial

[tex]2x^5+3x^2+3[/tex]

Any polynomial with 3 terms is a trinomial, so it is a trinomial.

It is clear that '5' is the highest power of the 'x' variable. so, the polynomial has a degree of 5.

'3' is the constant term. The reason is that any term with no variable is called a 'constant' term. So, '3' is the constant term.

Therefore, [tex]2x^5+3x^2+3[/tex] is a trinomial having with:

three terms degree 5 and The constant term '3'

Step-by-step explanation:

A population of values has a normal distribution with μ = 245.3 and σ = 96 . You intend to draw a random sample of size n = 50 . Find the probability that a single randomly selected value is greater than 246.7. P(X > 246.7) = 0.0146 Incorrect Find the probability that a sample of size n = 50 is randomly selected with a mean greater than 246.7. P(M > 246.7) = Enter your answers as numbers accurate to 4 decimal places. Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.

Answers

Answer:

0.4589

Step-by-step explanation:

We solve using z score formula

The z score formula for a random number of samples is:

z = (x-μ)/σ/√n, where x is the raw score, μ is the population mean, and σ is the population standard deviation

Hence:

z = 246.7 - 245.3/96/√50

z = 0.10312

Probability value from Z-Table:

P(x<246.7) = 0.54107

P(x>246.7) = 1 - P(x<246.7) = 0.45893

Approximately to 4 decimal places = 0.4589

The probability that a single randomly selected value is greater than 246.7 is 0.4589

What are the negative and positive coterminal angles of 240 degrees?

Answers

-120 negative and 600 positive.

The negative and positive coterminal angles of 240 degrees will be -120 negative and 600 positive.

What are coterminal angles?

Two different angles that have identical starting and ending edges are termed coterminal angles however since one angle is measured clockwise and the other is determined counterclockwise, the angles' terminal sides have completed distinct entire rotations.

We have to find the coterminal angles of 240 degrees

Coterminal angles are those whose initial and terminal sides coincide. Depending on whether the given angle is in degrees or radians, adding or subtracting 360° or 2 from each angle yields the coterminal angles. There are countless coterminal angles that can be discovered.

Thus, the negative and positive coterminal angles of 240 degrees will be -120 negative and 600 positive.

Five different awards are to be given to three students. Each student will receive at least one award. In how many different ways can the awards be distributed?

Answers

Answer:

Two ways

Step-by-step explanation:

Blue is students and Yellow is the trophies.

Total number of different ways that the awards can be distributed is; 150 ways.

It is clear from the question that the awards and the students are different. Now, each student will receive at least one award.

This means that the five different awards could be separated into;

3 + 1 + 1 awards or 2 + 2 + 1 awards.

Now, for one person to get 3 awards and the other 2 people to get one award each, the number of ways is calculated as;

       ⁵C₃ × 3! = 60 ways

Now, for the case where one person is to get 1 award and the other 2 people to get two awards each, the number of ways is calculated as;

      ((⁵C₂ × ³C₂)/2) × 3! = 90 ways

Thus; total number of ways the awards can be distributed = 60 + 90 = 150 ways.

Deion divided 1/2 of a liter of plant fertilizer evenly among some smaller bottles. He put 1/8 of a liter into each bottle. How many smaller bottles did Deion fill?

Answers

Answer:

4 bottles

Step-by-step explanation:

Given

[tex]Fertilizer = \frac{1}{2}L[/tex]

[tex]Bottles = \frac{1}{8}L[/tex]

Required

Determine the number of bottles

Represent the number of bottles with N

This implies that N bottles of [tex]\frac{1}{8}L[/tex] fit into [tex]\frac{1}{2}L[/tex] of fertilizer. The relationship between them is:

[tex]Fertilizer = Bottles * N[/tex]

[tex]\frac{1}{2}L = \frac{1}{8}L* N[/tex]

[tex]\frac{1}{2} = \frac{1}{8}* N[/tex]

Multiply through by 8

[tex]8 * \frac{1}{2} = 8 * \frac{1}{8}* N[/tex]

[tex]4 = 1* N[/tex]

[tex]4 = N[/tex]

[tex]N = 4[/tex]

Answer:

  64r -48r -144

Step-by-step explanation:

The January cost expression is ...

  62p -48p -144 -432 = profit

The cost is identified as having 3 components, so the profit will have 4 components:

  (selling price)×p - ((cost per unit)×p +(fixed monthly cost)) -(first month startup cost) = profit

Comparing this to the given equation, we identify the components as ...

  selling price = 62

  cost per unit = 48

  fixed monthly cost = 144

  first month startup cost = 432

We note that 432 = 3×144, so is consistent with the description of startup costs.

Increasing the selling price by $2 will raise it from 62 to 64. In February, the initial month startup cost disappears, so the profit equation becomes ...

  (selling price)×r - ((cost per unit)×r +(fixed monthly cost)) = profit

  64r -48r -144 = profit

simplify the square root of 272​
