Answer:
0.66% probability that exactly 40 of the murders were Cleared.
Step-by-step explanation:
For each murder, there are only two possible outcomes. Either it was cleared, or it was not cleared. The probability of a murder being cleared is independent of other murders. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
64% of murders committed last year were cleared by arrest or exceptional means.
This means that
Fifty murders committed last year are randomly selected.
This means that
Find the probability that exactly 40 of the murders were Cleared.
This is P(X = 40).
0.66% probability that exactly 40 of the murders were Cleared.
Okayyy, so the answer is 7.830. Adding a negative number is the same as subtracting a positive number so you can rewrite it as d-5.004=2.826, then you will add 5.004 to 2.826 and for your answer you will get 7.830.
Answer:
=5.8
ig find the one that is rounded closely to that
To get the previous population you would have to multiply 9,300 by 38% (.38) and then add it to 9,300, or you can also multiply it by 138% (1.38) and still get the same answer but this step is only a one step the first is a two step process
637 is the answer because our value is 980 we all know the unknown value with x for the step above 980 and 100% and 65% is the result in a pair of a simple equations
