All of them are involved with variables. :)
Answer:
The probability that a randomly selected day will generate more than $6,000 in revenue is 0.325.
Step-by-step explanation:
The frequency distribution of daily revenue for an Italian restaurant in Wilmington, Delaware is:
<u>Revenue</u> <u>Frequency</u>
Under $2,000 18
$2,000 - $4,000 10
$4,000 - $6,000 26
$6,000 - $8,000 14
$8,000 - $10,000 8
Over $10,000 4
Total 80
The probability of an event <em>E</em> is defined as:

Here,
n (E) = favorable outcome
N = total outcomes
The favorable outcomes of the event <em>X</em> : "more than $6,000 in revenue" is defined as:
n (X) = 14 + 8 + 4 = 26
Total number of outcomes is, <em>N</em> = 80.
Compute the probability of the event <em>X</em> is:

Thus, the probability that a randomly selected day will generate more than $6,000 in revenue is 0.325.
Answer:
1. 4 categories are shown in the rows.
2. 2 categories are shown in the columns.
3. The number of 14 year olds that consider winter their favorite season is 12.
4. Total number of people polled is 82.
Step-by-step explanation:
The question is to test the ability of a student to group data using a frequency table accurately, and make appropriate deductions from it. Consider the attachment for the accurate table required to answer the given questions.
If the given information is grouped as required, thus the answers to the questions are:
i. 4 categories are shown in the rows.
ii. 2 categories are shown in the columns.
iii. The number of 14 year olds that considers winter their favorite season is 12.
iv. Total number of people polled is 82.
Assuming that 80 and 18 are the legs, the hypotenuse is 82yds.
