Answer:

The 4 possible outcomes are HH, HT, TH, TT.

So theoretically, HH should occur 1in 4 times.

1/4 = x/20

x = 5

So why is it actually 2 in 20 when theoretically it should be 5 in 20? One reason is that theoretical probabilities gain more accuracy with larger numbers of results (e.g tossing the coins 100 times). You can likely think of some more reasons.

Request: Please mark me as the brainliest.

erica [24]
Total number of stocks bought = 20
Rate at which each stocks were bought = 31 1/2
                                                             = 63/2
Rate at which 20 stocks were bought = 20 * (63/2) dollars
                                                             = 10 * 63 dollars
                                                             = 630 dollars
Rate at which each stocks were sold = 35 1/4
                                                             = 141/4 dollars
Rate at which 20 stocks were sold = 20 * (141/4) dollars
                                                         = 5 * 141 dollars
                                                         = 705 dollars
Then
Amount of profit made by selling 20 stocks = (705 - 630) dollars
                                                                      = 75 dollars
So the total amount of profit made is $75. The correct option in regards to the given question is option "D".

Answer:

The percentage of the markup is 82%

Step-by-step explanation:

In this question, we are asked to calculate the percentage of mark up. This is simply calculating the percentage of the profit margin.

firstly to be able to calculate this percentage, we need to know the value of the profit margin itself.

mathematically, the profit margin is selling price - cost price

From the question, the selling price is $1 while the cost price is 55 cents

The profit margin is thus $1 - 55 cents = 45 cents

We now proceed to calculate the percentage profit

mathematically, that is profit/cost price * 100%

That would be 45 cents/55 cents * 100 = 9/11 * 100% = 81.8 approximately 82%

What is the answer to -3+p=?
nata0808 [166]
There is not an answer to an expression. 

-3+p is an expression, unless there was an equal sign and a sum at the end, that is when we can solve for the variable x. 

-3+p simply equals -3+p
