Complete Question:
The conditional relative frequency table was generated using data that compared the cost of one ticket for a performance and the method by which the ticket was purchased.
Given that Lorenzo paid more than $30 for a ticket, what is the probability that he purchased the ticket at the box office? Express the answer in decimal form
Answer:
0.14
Step-by-step explanation:
From the attached diagram, we were given a table that contained known values:
The number of tickets that were purchased online we have 2 categories
a) Not more than $30 = 0.7
b) More than $30 = 0.86
The number of tickets that were purchased at the box office also had 2 categories.
a) Not more than $30 = 0.3
b) More than $30 = 0.14
The probability that the ticket Lorenzo paid more than $30 for was purchased at the box office
= P( more than $30 at the box office)
= 0.14
To work out what percent of 60 is 150 just do the following:
150 / 60 = 2.5
2.5 x 100 = 250
Therefore 150 is 250% of 60. Hope I helped!
Answer:
(D), Predicting.
Step-by-step explanation:
Descriptive statistics involves various methods of collection, analysis , presentation as well as the summarization of a data set. It is involved in understanding the characteristics of the data by measuring the central tendency and measure of dispersion. Thus, it could be concluded that the prediction of the data is not done by the descriptive statistics.
Hence, the correct option is (D), Predicting.
Answer: 21.8
Step-by-step explanation:
Pythagorean Theorem = a^2 + b^2 = c^2
5^2 + b^2 = 10^2
25 + b^2 = 100
b^2 = 75
b = 8.7
area = 1/2bh
1/2 5x8.7
1/2 43.5
21.8
