Answer:
59.87% probability of randomly selecting 10 production employees on a hot summer day and finding that none of them are absent
Step-by-step explanation:
For each employee, there are only two possible outcomes. Either they are absent, or they are not. The probability of an employee being absent is independent from other employees. So we use the binomial probability distribution 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.
5% of the production employees at Midland States Steel are absent from work.
This means that
What is the probability of randomly selecting 10 production employees on a hot summer day and finding that none of them are absent
This is P(X = 0) when n = 10. So
59.87% probability of randomly selecting 10 production employees on a hot summer day and finding that none of them are absent
Answer:
Explanation:
Follow PEMDAS in reverse to undo what's happening to x.
We first add 1 to both sides, then divide both sides by 5 to fully isolate x.
Refer to the steps below to see what I mean.
The inequality sign stays the same the entire time. The only time it flips is when you divide both sides by a negative number.
The solution set for x is anything -3 or larger.
If x was an integer, then we could say the solution set is {-3, -2, -1, 0, 1, 2, 3, 4, 5, 6, ...}
