1. Find the Least Common Multiple of these two monomials:<br> See picture
gtnhenbr [62]

Answer:

<em>The last choice is correct</em>

<em />LCM=120a^4b^7c^5<em />

Step-by-step explanation:

<u>Least Common Multiple (LCM)</u>

To find the LCM we can follow this procedure:

List the prime factors of each monomial.

Multiply each factor the greatest number of times it occurs in either factor.

We have two monomials:

12a^4b^2c^5

40a^3b^7c^1

The prime factors of the first monomial are:

2^2,3,a^4,b^2,c^5

The prime factors of the second monomial are:

2^3,5,a^3b^7c^1

LCM = Multiply 2^3*3*5*a^4*b^7*c^5

These are all the factors the greatest number of times they occur.

Operating:

LCM=8*15*a^4*b^7*c^5

\boxed{LCM=120a^4b^7c^5}

The last choice is correct

To maximize the probability that customers purchase products during a visit to a​ website, a company that provides marketing ser
Gelneren [198K]

Answer:

A. Diagram attatched

B. 4.7%

C. 0.42

Step-by-step explanation:

A. In order to understand the probability tree, we have to define three different scenarios that could happen when certain customer visits the website:

1. Discount (30%)

2. Free shipping (40%)

3. No special offer, (it must be 30% because all gives a total of 100%)

Then, for each scenario two things could happen, customer makes a purchase or not. Given the information above, each branch of the tree has the specified percentage of occurrence or probability.  

B. Once the probability tree is made, the next step is to multiply the percentages of each consecutive branch. For example:

  • The percentage of customers that visit the website, receive free shipping and make a purchase is 40% x 5 %, as it has been specified in the picture.  

Then, after calculate all percentages of customers that make a purchase, it is necessary to add them to finally get a total of 4.7%.

C. We can understand it as follows:

The customers are divided between three main sets:

  • Those who were offered with special discount.
  • Those who were offered with free shipping.
  • Those who received no special offer.

Inside these sets there is the set of costumers who made a purchase, and we have already that percentage, it is 4.7%. However, to determine the asked probability, we have to keep our attention in the intersection between the set of those who were offered with free shipping and those who made a purchase. The percentage of that tiny set over the percentage of customers who made a purchase, is the probability that we must determine:

P ( B│A)=(P(A∩B))/(P(A))=0.02/0.047=0.42

Where A: the costumer made a purchase

            B: the costumer received an offer of free shipping

The probability that a costumer were offered with free shipping given that he made a purchase is 0.42.
