Answer: 680 different combinations</h3>
=======================================================
Explanation:
If order mattered, then we'd have 17*16*15 = 4080 different permutations. Notice how I started with 17 and counted down 1 at a a time until I had 3 slots to fill. We count down by 1 because each time we pick someone, we can't pick them again.
So we have 4080 different ways to pick 3 people if order mattered. But again order doesn't matter. All that counts is the group itself rather than the individual or how they rank. There are 3*2*1 = 6 ways to order any group of three people, which means there are 4080/6 = 680 different combinations possible.
An alternative is to use the nCr formula with n = 17 and r = 3. That formula is
where the exclamation marks indicate factorials
Answer:
The correct answer is option (E)
Step-by-step explanation:
Solution to the question
Let us recall from given question that,
H0:p=0.80
Ha:p≠0.80 (which is the two tailed test)
For the p-value we have,
P-value: Let us assume that the null hypothesis is true, then the probability of observing the sample statistics or the more extreme,
Therefore if p= 0.80, the probability of observing or detecting proportion of samples is of at least 0.84 or at most 0.76 is 0.273.
Answer:
The value is
Step-by-step explanation:
From the question we are told that
The number of light produced in an hour is n = 922
The proportion of the bulb that are defective is p = 0.0334
Generally given from the question that we should use binomial distribution it then means that the standard deviation is mathematically evaluated as

Answer:
Fraction
Step-by-step explanation:
Fraction is a symbol that represents a part of a whole. It consists of a <em>numerator</em> and a <em>denominator. </em>The numerator is the number above the fraction bar (also known as "Vinculum), while the denominator is the number below the fraction bar. The denominator is the total number of equal parts in a whole.
Examples of Fraction: , and .
In the first example, , 1 is the numerator, while 2, is the denominator.
<u>Additional Information</u>
When the numerator is smaller than the denominator, the fraction is called <em>"proper fraction."</em> On the contrary, when the numerator is bigger than the denominator, the fraction is called <em>"improper fraction."</em>
