Therefore, the hiker's hiked
more in the morning than in the afternoon.
Answer:
A = 2x²-3x-5
Step-by-step explanation:
Given that,
The length of the bedroom, l = (2x-5)
Width of the bedroom, b = (x+1)
We need to find an equation for the area of the bedroom. We know that,
Area of a rectangle = lb
Put all the values,
A = (2x-5)(x+1)
= 2x²+2x-5x-5
= 2x²-3x-5
Hence, the area of the bedroom is equal to 2x²-3x-5.
Answer:
Step-by-step explanation:
1) 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".
2) Solution to the problem
The probability in favor of the regulation based on the recent survey is:

Let X the random variable of interest "Number of favor respondents about the regulation", 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:
If we use X= "Number of respondednts opposed to the regulation we got the same answer", but on this case p = 1-0.68=0.32, and we want this probability:
