Answer:
Square root of 87.35 will be plotted between 9 and 10 as shown below.
Step-by-step explanation:
We are given that, 'The number line is numbered in tenths'
Also, the square root of 87.35 is given by,
That is, we have to plot the point 9.4 on the number line numbered in tenths.
As, 9.4 will lie between the points 9 and 10.
Thus, we get that square root of 87.35 will be plotted between 9 and 10 as shown below.
Answer:
0.055 = 5.5% probability that exactly 5 employees were over 50.
Step-by-step explanation:
The employees are removed from the sample without replacement, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x successes is given by the following formula:
In which:
x is the number of successes.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
In this question:
7 + 18 = 25 employees, which means that
7 over 50, which means that
10 dismissed, which means that
What is the probability that exactly 5 employees were over 50?
This is P(X = 5). So
0.055 = 5.5% probability that exactly 5 employees were over 50.
