The answer is D. 9(y+3) and 27 + 9y
You would distribute the 9 to both the 3 and the y.
There can not be equal sharings since 16/5 does not equal a whole number! Good luck :)
Answer:
<em>D.</em><em> He can increase the number of trials.</em>
Step-by-step explanation:
Jonas is conducting an experiment using a 10-sided die. So the theoretical probability of rolling a 3 in a single trial is,
So the theoretical expected outcome of 3 in 20 roll would be,
But when he rolled the die 20 times, where four of those rolls resulted 3.
Which is 2 times more than the theoretical expectation.
Increasing the number of trials from 20, the expected outcome will increase.
As the number of trials is multiplied with , so bigger the number is from 20, bigger the value.
As we know,
If we want to increase the expected value, we have to increase the number of trials.
Answer: i
Step-by-step explanation:
It is imaginary, since if you try squaring numbers, ex: -1, 1,0,2 you always get a number bigger or equal to 0.
For years mathematicans argued weather the square root of -1 (or any negative number) should exist.
Then one day, a mathematician proposed a soulution, the square root of -1 could be i. Everyone liked that and so now the square root of -1 is i
