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.

Step-by-step explanation:
<em>Refer to attache</em>d
Since 40 oz is total
<u>The weight of each shape indicated in the picture and calculated as:</u>
- 40/2 = 20 oz
- 20/2 = 10 oz
- 10/2 = 5 oz
As each inch weights 1 oz, there must be 5 of each shapes included in the kit
Answer:
x≥29
Step-by-step explanation:
25≤x−4
move terms
-x≤-4-25
calculate
-x≤-29
change signs
x≥29
250x855=213,750-6,780=206,970/100=2,069.7x15=31,045.5 So the answer is C.
