You bought 100 shares of stock at $15 per share. You sold your 100 shares at $21.75 per share. Calculate your total profit from the sale.

Answers

Answer:

$675

Step-by-step explanation:

You multiply 15 and 100 answer for that is 1500 then you multiply 21.75 and 100 answer for that is 2175 finally you subtract 1500 from 2175 witch gives you the final answer of 675

Total profit from the sale of 100 shares is equals to $675.

What is profit?

" Profit is the amount of money or revenue which we earned when selling price of a product is more than its cost price."

Formula used

Profit = Selling price - Cost price

According to the question,

Cost price of 1 share = $15

Therefore,

Cost price of 100 shares = 15 × 100

= $1500

Selling price of 1 share = $21.75

Selling price of 100 shares = 21.75 ×100

= $2175

Selling price > Cost price

Therefore , Profit

Substitute the value in the formula we get,

Profit = 2175 - 1500

= $675

Hence, total profit from the sale of 100 shares is equals to $675.

Solve using substitution
y = 4x + 11
2x – 5y = -1

Answers

Answer:

x=−3 and y=−1

Step-by-step explanation:

Substitute y=4x+11y=4x+11 into 2x-5y=-12x−5y=−1

-18x-55=-1−18x−55=−1

Solve for x in -18x-55=-1−18x−55=−1.

x=-3

Substitute x=-3x=−3 into y=4x+11y=4x+11.

y=-1

Answer:

Step-by-step explanation:

2x-5(4x+11)=-1

2x-20x+55=-1

-22x+55=-1

-22x+55-55=-1-55

-22x/-22=-56/-22

x=28

X + 2y = 7
2x + y = 5
What’s the substitution

Answers

You can subtract 2y from both sides of the first equation and then plug that (x = 7 -2y) into the second one to get:

14 - 4y + y = 5 -->

14 - 3y = 5 -->

-3y = -11 -->

y = 11/3 -->

x = 2/3

what is the slope and y-intercept of y=4x+2

Answers

Answer:

slope: 4

y-intercept: 2

Step-by-step explanation:

We are given an equation, y = 4x + 2, and we are asked to find the slope and y-intercept of the line. Looking carefully, we can see that the equation is given to us in slope-intercept form.

Slope-intercept form is:

y = mx + b

where m is the slope and b is the by-intercept.

Knowing this, we can find that 4 is the slope of the line and 2 is the y-intercept.

This is a lot of questions-

I did them all on a calculator.

1.)

3x - 4 + 6x = -31

3x + 6x - 4 = -31

9x - 4 = -31

9x = -27

Answer: x= -3

2.)

17 = 3x - 10

3x -10 = 17

-10 = -10

3x = 27

divide both sides by 3

Answer: x= 9

3.)

2x + 6 = 4x - 8

-6 = -6

2x = 4x -14

-4x (both sides)

-2x = -14

divide both sides by -2

Answer: x = 7

4.)

17x - 5(3x - 11) = 41

2x +55 = 41

-55 (both sides)

2x = -14

divide 2 both sides

Answer: x = -7

5.)

5x - (3x - 6) = 18

2x + 6 = 18

-6 both sides

2x = 12

divide both sides by 2

Answer: x = 6

6.)

6x - 3(4 - 5x) = 30

21 - 12 = 30

+12 boh sides

21x = 42

divide both sides by 21

Find the variation constant and an equation of variation for the given situation.

y varies directly as x, and y = 7 when x = 1/2.

Answers

Answer:

[tex]\displaystyle y=14\cdot x[/tex]

Step-by-step explanation:

Directly Proportion

It's said that y varies directly proportional as x, if:

[tex]y=k\cdot x[/tex]

Where k is a constant of proportionality.

We know that y=7 when x=1/2.

Using the above condition, we can find the value of k:

[tex]\displaystyle 7=k\cdot \frac{1}{2}[/tex]

Solving for k:

k=14

Thus, the equation is:

Identify whether this will be normal distribution or skewed left or right? (Hint: find the five number summary and make a box plot)
O skewed left
O skewed right
O normal distribution

Answers

The answer is skewed in the right direction

The distribution of set A is a normal distribution

The data in set A is given as:

1 3 3 2 4 0 4 3 3 5 2

Represent the dataset as a plot, as follows

2 2

3 3 3 3

4 4

Notice that the plot above increase from 0, then reaches a maximum at 3, and then decreases from 3 to 5

This implies that it follows a bell curve.

When a distribution follows a bell curve, such data is a normal distribution.

Hence, the distribution is a normal distribution
