Suppose you were told that the company built the fence 4 hours and that they completed 1\6 mile of the fence each hour. How woul
d you use the double number line to help you find he length of the fence?
1 answer:
Answer:
Given,
Time spent in fencing = 4 hours,
Length fenced in each hour = miles.
We need to find : The length of the fence.
By using the double number line to solve this problem,
We will follow the following steps,
Step 1 : Draw two straight parallel lines, first represents time in hours second represents length in miles.
Step 2 : Make 4 tick marks in first line in which each mark represents each hour.
Step 3 : Make corresponding 4 marks in second line.
Step 4 : If first tick in second line represents 1/6 then it is obvious that last tick mark represents 4/6 or 2/3.
Hence, the length of fence is 2/3 miles.

Answer:
Step-by-step explanation:
For each name, there are only two outcomes. Either the name is authentic, or it is not. So, we can solve this problem using the binomial probability distribution.
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 combinatios of x objects from a set of n elements, given by the following formula.
And is the probability of X happening.
In this problem.
5 names are selected, so
A success is a name being non-authentic. 40% of the names are non-authentic, so .
We have to find
Either the number of non-authentic names is 0, or is greater than 0. The sum of these probabilities is decimal 1. So:
So
