From the question we are told that
The mean is 
The standard deviation is 
Generally for the probability to be 4% the minimum guaranteed mileage is evaluated as
=> 
=> 
From the z table, the critical value corresponding to 0.96 to the left of the curve is
So
=>
Answer:
8
Step-by-step explanation:
total paid: $135.95
cost of gloves: $15.95
amount for classes: $135.95 - $15.95 = $120
cost of each class: $15
number of classes: $120/$15 = 8
Answer: 8 classes
Answer:
c. 3324
Step-by-step explanation:
We need to use the formula of Geometric CDF with π =0.02
P(x≤20) = 1 - (1-0.02)^20
P(x≤20) = 1 - (0.98)^20
P(x≤20) = 1 - (0.98)^20
P(x≤20) = 1 - 0.6676
P(x≤20) = 0.3324
Therefore the probability that the first such ejection occurs within the first 20 Visa transactions is 0.3324
Answer:
B. Pie chart.
Step-by-step explanation:
In this question, the students are asked what political party they belong. The best display format would be one in which the graph can be divided into parts, or percents, according to the percentage of students belonging to each political party. The graph that best describes this, distributing a group into parts, is a pie chart, and thus, the correct answer is given by option b.
Scatterplot is used when two variables correlate together, that is, there is a relationship between them, which we don't have between the number, or proportion of students belonging to each political party. Stemplot are used when there is a high number of quantitative data, which we do not have here.
