Answer:
Using the probability mass function we got:
And adding the probabilities we got:
Step-by-step explanation:
Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
Solution to the problem
For a fair coin flip n=28 times we have the following distribution:
We want to find this probability:
Using the probability mass function we got:
And adding the probabilities we got:
Answer:
xy-xz+yz-yx+zx-zy hoped this helped a little
Step-by-step explanation:
Answer:
-6/(v^2 -8)
Step-by-step explanation:
(-6u - 9)/(v^2 -8) + (6u + 3)/(v^2 -8)
Since we have common denominator terms, we can add both fraction terms
(-6u+6u -9+3)/(v^2 -8)
Now we have
-6/(v^2 -8)
Answer:
1710 ft^3
Step-by-step explanation:
V=18*6 1/3*15
V=5130/3
V=1710
Q1. The answer is <span>1 over 5 to the 3rd power.
</span>5 to the 5th is 5⁵
5 to the 8th is 5⁸
5 to the 5th over 5 to the 8th is
To simplify, we will use two rules:
Therefore:
is the same as 1 over 5 to the 3rd power.
Q2. The answer is <span>(53)−4.
The exponents are multiplied when are expressed in the form:
</span>
So,
Other choices are incorrect:
<span>one third to the 4th times one third to the 7th is </span>
3 to the 7th over 3 to the 15th is
<span>45 ⋅ 42 is </span>
