C: 1/2x +7
Step-by-step explanation:
Answer:
And using the probability mass function 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".
Solution to the problem
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:
And we want to find this probability:
And using the probability mass function we got:
Answer:
9.35
Step-by-step explanation:
because you take 3.5 away from 12.85
Answer:
20.92 km
Step-by-step explanation:
8.045 km/5 miles = 1.609 km per mils
1.609 x 13 = 20.92 km
Answer:
The area is:
Step-by-step explanation:
The area under the standard normal curve equals the z probability.
We look for the area of the region that is not shaded.
That is, we look:
Then we must find
Looking in the standard normal probability table we have to:
So:
