Miguel paid a total of $12,000 for stock that was $8 per share. If he sold his shares for $15,000, how much profit on each share did he make?

Answers

The correct answer is:

$2 per share.

Explanation:

He paid $12000 total, at a rate of $8 per share. This means he bought 12000/8 = 1500 shares.

He sells these 1500 shares for $15000; this means he received 15000/1500 = $10 per share.

This means he made 10-8 = $2 profit per share.

Answer:

Step-by-step explanation:

Cost of 1 share = $8

He bought Shares for amount $12,000

So, He bought number of shares = $(12000)/(8)$

= $1500$

Now he sold 1500 shares for amount $15000.

So, S.P. of 1 share = $(15000)/(1500)$

= $10$

So, S.P. of 1 share = $10

C.P. of 1 share = $8

So, profit = S.P. - C.P.

= $10-$8

=$2

Thus he made $2 as profit on each share.

A cylindrical water tank is being filled with a hose. The depth of the water increases by 1 1/4 ft per hour. How many hours will it take for the water level in the tank to be 3 1/2 ft deep?

Answers

A water tank has the shape of an inverted right circular cone with an altitude of 12ft anda base radius of 6ft. If water is being pumped into the tank at a rate of 10 gal/min(1.337f t3/min, approximate the rate at which the water level is rising when the water is 3 ft deep.hr126We know dvdt = 1.337, h = 3. We alsohave the relationship between h and r by using similar triangles.rh = 612or that r = 12hV = 13πr2h = 13π12h2h = 112πh3dVdt = 14πh2 ∗dhdt now plug in the info and solve for dhdtAnswer: dhdt = .1891f t/min

Which of the following is not a factor involved in the process of evaluating an observational study?Introduction
Results
Discussion
Bias

Answers

Answer:

The answer is D, bias. If bias were a factor in an observational study(which it is not), then the study would be inaccurate due to someone's personal views affecting the results. Therefore bias is not a factor in the process of evaluating an observational study.

I don't know who verified the answer of the person why thought the answer was A, but they were incorrect.

Results and Discussion are definitely very relevant for examining an observational study - they contain the core of the study, so they will definitely be considered when evaluated.
So we choose between "Bias" and "Introduction".

I think that the correct answer is "Introduction" -as it doesn't include any new information about the study, and only summarizes previous work.
