Answer:
Non terminating recurring decimals
Step-by-step explanation:
Decimals can be categorised into two groups: Terminating and non-terminating. Terminating decimals are rational, and non terminating can be further divided into: Non terminating Recurring (which are rational) and Non terminating Non recurring (which are irrational).
The total capacity of the pool = 18000 gallon
The total volume of the pool when calculated to 2/5 = (2/5) * 18000
= 35000/5 gallons
= 7200 gallons.
Now it is given in the problem that that
Rate at which the pool is filled with water = 20 gallons per minutes
Then
20 gallons of water is filled in = 1 minute
So
7200 gallons of water will be filled in = 7200/20 minute
= 720/2 minute
= 360 minute
So 360 minute is required to fill the pool with 2/5 of the total volume of water.
Answer:
0.9021 = 90.21% probability that 10 or fewer customers choose the leading brand
Step-by-step explanation:
For each customer, there are only two possible outcomes. Either they choose the leading brand, or they do not. The probability of a customer choosing the leading brand is independent of any other customer, which means that the binomial probability distribution is used 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.
The leading brand of dishwasher detergent has a 30% market share.
This means that
A sample of 25 dishwasher detergent customers was taken.
This means that
a. What is the probability that 10 or fewer customers choose the leading brand?
This is:
In which
Then
0.9021 = 90.21% probability that 10 or fewer customers choose the leading brand
