Answer:

Theoretical Probability: 1/2

Actual Probability: 17/40

Step-by-step explanation:

When you toss a coin, it can land on one of either Heads, or tails. This is a 1 out of 2 (or 1/2) chance of each happening. This is the theoretical probability, since real life will most likely not follow this exactly, as shown by the tests in the question.

In the question, it says that it landed on heads 17/40 times, meaning that the probability is 17/40.

You add by +4.

Step-by-step explanation:

-5 + 4 = -1

-1 + 4 = 3

Two ways you could evaluate 37% of the sum of 27 3/5 and 15.9 plz answer as soon as you can
zhannawk [14.2K]

Answer:

16.095.  

Step-by-step explanation:

We can either find 37% of both the numbers and add the results, or we can add the numbers and then find the 37% of the sum.  

1. Let us find 37% of both numbers separately.

First of all we will convert our mixed fraction into improper fraction.

27\frac{3}{5}=\frac{138}{5}

37% of 27\frac{3}{5} will be,

\frac{138}{5}\times \frac{37}{100}=\frac{138}{5}\times 0.37

27.6\times 0.37=10.212

Now let us find 37% of 15.9.

15.9\times \frac{37}{100}=15.9\times 0.37=5.883

Now let us add 37% of both numbers.

10.212+5.883=16.095  

Therefore, 37% of our given numbers will be 16.095.

2. Now we will add both numbers and then find 37% of their sum.

27\frac{3}{5} +15.9=\frac{138}{5}+15.9

27.6 +15.9=43.5

Now let us find 37% of 43.5.  

43.5\times\frac{37}{100}=43.5\times 0.37=16.095

Therefore, 37% of 43.5 is 16.095. We have seen that using either way we got the same answer.
