Answer:
Unique
Step-by-step explanation:
Let y₁ = 1 - ⁴/₃x (1)
and y₂ = ½(–x + 7) (2)
The slope of Equation (1) is -⁴/₃.
The slope of Equation (2) is -½.
The slopes are different, so there is a unique solution set.
Answer:
(a) The expected number of should a salesperson expect until she finds a customer that makes a purchase is 0.9231.
(b) The probability that a salesperson helps 3 customers until she finds the first person to make a purchase is 0.058.
Step-by-step explanation:
Let<em> </em>the random variable <em>X</em> be defined as the number of customers the salesperson assists before a customer makes a purchase.
The probability that a customer makes a purchase is, <em>p</em> = 0.52.
The random variable <em>X</em> follows a Geometric distribution since it describes the distribution of the number of trials before the first success.
The probability mass function of <em>X</em> is:
The expected value of a Geometric distribution is:
(a)
Compute the expected number of should a salesperson expect until she finds a customer that makes a purchase as follows:
This, the expected number of should a salesperson expect until she finds a customer that makes a purchase is 0.9231.
(b)
Compute the probability that a salesperson helps 3 customers until she finds the first person to make a purchase as follows:
Thus, the probability that a salesperson helps 3 customers until she finds the first person to make a purchase is 0.058.

Answer:
With one new spool of ribbon containing 30 1/2 feet Sarah can wrap 11 medium boxes using 2 3/4 feet of ribbon on each.
I hope this answers your question as there was not a specific question
Step-by-step explanation:
30 1/2 feet of ribbon= 366 inches of ribbon
2 3/4 feet of ribbon= 33 inches of ribbon
33/366=11.09
