Complete question:
overnight shipping business has skyrocketed in the last ten years. The single greatest predictor of a company's success is customer service. A study was conducted to determine the customer satisfaction levels for one overnight shipping business. In addition to the customer's satisfaction level, the customers were asked how often they used overnight shipping. The results are shown in the following table: Frequency of Use High Satisfaction level Medium Low TOTAL< 2 per month 250 140 10 400 2 - 5 per month 140 55 5 200 > 5 per month 70 25 5 100
TOTAL 460 220 20 700
Suppose that one customer who participated in the study is chosen at random. What is the probability that the customer had a medium level of satisfaction and used the company more than five times in a month
Answer: 0.03571
Step-by-step explanation:
To determine probability that a customer had a medium level satisfaction and used company more than 5 times a month
Total number level of satisfaction = 700
Customer that had Medium level satisfaction and used company more than five(5) times a month(>5) is 25 from the table
Therefore, Probability = 25/700
Probability = 1/28
Probability = 0.03571
Answer:C
Step-by-step explanation:
The y-coordinate that completes the point exists 5.
<h3>What is an ordered pair?</h3>
An ordered pair (x, y) denotes the x-and-y coordinates of a general point, where x exists the input value of a function and y exists the output value of a function.
The output value exists y = f(x) and must be found using the rule (function) to the given input value.
In this case the rule exists f(x) = - 3x + 2, and the input value, x, exists - 1 (the first value of the ordered pair).
This exists the mathematical procedure:
x = - 1
f(x) = f (-1)
Then substitute the value x = -1 then
f(-1) = -3 (-1) + 2 = 3 + 2 = 5.
Therefore, the correct answer is option b) 5.

Answer: D. The probability of a time from 75 seconds to 250 seconds.
Step-by-step explanation:
We know that a density curve graph for all of the possible values from a to b can be used to find the the probability of the values from a to b .
Given: A density graph for all of the possible times from 50 seconds to 300 seconds.
Then it can be used to find the the probability of a time in the range from 50 seconds to 300 seconds.
From all the given option only option D gives the interval which is lies in the above range.
i.e A density graph for all of the possible times from 50 seconds to 300 seconds can be used to determine the probability of a time from 75 seconds to 250 seconds.
