A car dealer purchases a car for $5,000 and sells for $6,600 what is his percentage profit? Round your answer to the nearest whole percent

Answers

Answer:

  32%

Step-by-step explanation:

The percentage profit is the ratio of profit to original cost, expressed as a percentage. The profit is the difference between the selling price and the cost.

  profit = selling price - cost

  profit = $6600 -5000 = $1600

The ratio of that to cost is ...

  $1600/$5000 = 0.32

As a percentage, that is ...

  0.32 × 100% = 32%

The car dealer's profit was 32% of his cost.

You enter an online Esports tournament. The entry fee is $17, and the top 3 finishers win money. First place wins $325. Second place wins $276. Third place wins $106. You give yourself an X chance of finishing in the top 3, and if you finish top 3, then you have an equal chance of finishing first, second, or third. What is X such that entering this tournament is a fair gamble for you. A fair gamble is one where the expected value of entering the tournament is $0.

Answers

Using the expected value of a discrete distribution, it is found that X = 0.0673.

What is the mean of a discrete distribution?

The expected value of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.

In this problem, we have that the distribution is:

P(X = -17) = 1 - X.

P(X = 325) = X/3.

P(X = 276) = X/3.

P(X = 106) = X/3.

Hence, since the expected value is 0:

[tex]-17(1 - X) + 325\frac{X}{3} + 276\frac{X}{3} + 106\frac{X}{3} = 0[/tex]

[tex]-17 + 17X + 235.67X = 0[/tex]

[tex]252.67X = 17[/tex]

[tex]X = \frac{17}{252.67}[/tex]

[tex]X = 0.0673[/tex]

14 students have volunteered for a committee. Eight of them are seniors and six of them are juniors. (a) How many ways are there to select a committee of 5 students

Answers

Answer:  2002

======================================================

Explanation:

We have five slots to fill, which I'll label A through E.

There are,

14 choices for slot A13 choices for slot B12 choices for slot C11 choices for slot D10 choices for slot E

Each time we fill up a slot, we count down by 1.

This gives 14*13*12*11*10 = 240,240 different permutations. If order mattered, then this would be the answer.

However, order doesn't matter on a committee without rankings. Each member has the same rank as any other.

Within any group of 5 people, there are 5! = 5*4*3*2*1 = 120 ways to arrange them. This means we divide that 240,240 figure by 120 to find the number of combinations.

There are (240,240)/(120) = 2002 different combinations.

---------------------------------------

Here's how we could have done the problem using the nCr combination formula.

Plug in n = 14 and r = 5.

n C r = (n!)/(r!(n-r)!)

14 C 5 = (14!)/(5!*(14-5)!)

14 C 5 = (14!)/(5!*9!)

14 C 5 = (14*13*12*11*10*9!)/(5!*9!)

14 C 5 = (14*13*12*11*10)/(5!)

14 C 5 = (14*13*12*11*10)/(5*4*3*2*1)

14 C 5 = (240240)/(120)

14 C 5 = 2002

. A jeweler has 100 necklaces and bracelets to sell at a flea market. Bracelets are selling for $5.75 each, and necklaces are $8.50 each. If the jeweler makes $685.00 after selling all of the items, how many of each type of jewelry did the jeweler sell?

Answers

Answer:

there are total 60 bracelets and 40 necklaces.

Explanation:

let necklaces be x

let bracelets be y

make two equations from the given values:

x + y → 1005.75y + 8.50x → $685

solving steps:

x + y → 100

x → 100 - y

using substitution method:

5.75y + 8.5x → 685

5.75y + 8.5(100 - y) → 685

5.75y - 8.5y + 850 → 685

-2.75y → 685 - 850

-2.75y → -165

y → 60

Find x:

x + y → 100

x → 100 - 60

x → 40

Answer:

60 bracelets

40 necklaces

Step-by-step explanation:

Let n = number of necklaces sold

Let b = number of bracelets sold

Given:

Total number of items sold = 100

⇒ n + b = 100

Given:

Sale price of bracelet = $5.75Sale price of necklace = $8.50Total sales = $685

⇒ 5.75b + 8.5n = 685

Rewrite n + b = 100 to make b the subject, substitute into 5.75b + 8.5n = 685 and solve for n:

⇒ b = 100 - n

⇒ 5.75(100 - n) + 8.5n = 685

⇒ 575 - 5.75n + 8.5n = 685

⇒ 575 + 2.75n = 685

⇒ 2.75n = 110

⇒ n = 40

Substitute found value for n into n + b = 100 and solve for b:

⇒ 40 + b = 100

⇒ b = 60

The time at which the theatre does not have any customers is; Choice A: 11:00 PM

Functions and variable

From the task content;

The function which represents the number of customers the theater has at each point in time is;

C(x) = -x² + 11x

Hence, when C(x) = 0, the theater has no customers.

0 = -x² +11x

Divide through by x;

0 = -x +11

x = 11.

Hint :

y = ax + b

The coefficient of x is the slope of the line in this form of the linear equations.

=====================================

The perpendicular line have negative and inverse slope which means the product of their slope must equals to - 1 .

Thus if we suppose that the line we want to find it's equation has a slope of m ; we have :

4 × m = - 1

Divide both sides by 4

4m ÷ 4 = - 1 ÷ 4

m = - 1/4

Thus we know the coefficient of x now :

y = - 1/4 x + b

======================================To find the value of b we need one of the point that the line passed through it which is the point ( 4 , - 11 ) .

All we have to is put the coordinates in the equation and find the value of b.

Let's gooo....

y = - 1/4 x + b

put the coordinates in the equation

- 11 = (- 1/4)×4 + b

- 11 = - 1 + b

Add both sides 1

- 11 + 1 = -1 + 1 + b

b = - 10

======================================

Thus :

[tex]y = - \frac{1}{4} x + ( - 10) \\ [/tex]

[tex]y = - \frac{1}{4} x - 10 \\ [/tex]
