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:
40%
Step-by-step explanation:
38×100=3800÷95=40
40%×95=38
Answer:
P(1) = 0.31
Step-by-step explanation:
The total of all probabilities must be 1, so the missing number is ...
1 - 0.33 -0.14 -0.22 = 0.31
Answer:
The first term of the geometric series is 1
Step-by-step explanation:
In this question, we are tasked with calculating the first term of a geometric series, given the common ratio, and the sum of the first 8 terms.
Mathematically, the sum of terms in a geometric series can be calculated as;
S = a(r^n-1)/( r-1)
where a is the first term that we are looking for
r is the common ratio which is 3 according to the question
n is the number of terms which is 8
S is the sum of the number of terms which is 3280 according to the question
Plugging these values, we have
3280 = a(3^8 -1)/(3-1)
3280 = a( 6561-1)/2
3280 = a(6560)/2
3280 = 3280a
a = 3280/3280
a = 1
