Answer:

B) 0.167

Step-by-step explanation:

The student has 2 dice. We are assuming that both of those dice are limited at 6 (a number cube).

The first die needs to land on a number less than 3 (and it does not include 3). This means that there are two numbers that can meet the requirements, 1 & 2, which makes the chance 2/6, or 1/3.

The second die needs to land on a number greater than 3 (and it does not include 3). This means that there are 3 numbers that can meet the requirements, 4, 5, & 6, which makes the chances 3/6 or 1/2.

Multiply the two fractions together:

1/3 x 1/2 = 1/6

Divide, change to decimal:

1/6 = 0.167 (rounded)

B) 0.167 is your answer.

Antonio is buying a stereo, speakers, and amplifiers for his car audio system. He is choosing among 4 models of stereos and 3 st

d1i1m1o1n [39]

a) Option 3 - She should have multiplied the total of all the choices.

b) The total number of amplifiers is 3

Step-by-step explanation:

Step 1 :

Given,

Number of models of stereos Antonio can select from = 4

Number of styles of speakers Antonio can select from = 3

Number of brands available for Adele = 2

Number of Transmission available for Adele = 3

Number of bumpers available for Adele = 3

Number of roofs available for Adele = 2

Step 2:

From Step 1 , we can see that the total number of possible choices of vehicles Adele has = 2 × 3 × 3 × 2 = 36

Total possible choices as calculated by Adele = 2 + 3 + 3 + 2 = 10

Hence we can see that the error is that Adele has added the total possible choices instead of multiplying them.

So her error is as specified in option 3 - She should have multiplied the total of all the choices.

Step 4 :

Given number of total available choices = 36

We need to find the number of amplifiers. Let x be the number of amplifiers.

As we know from step 1 the total available choices for Antonio are

4 × 3 × x = 36

=>12 x = 36

=> x = $\frac{36}{12}$ = 3

Hence the total number of amplifiers is 3

Step 5 :

Answer :

a) Option 3 - She should have multiplied the total of all the choices.

b) The total number of amplifiers is 3

A Company received an invoice for $1618 dated May 11, terms 2/15 EOM.

Alona [7]

Answer:

26th of May is the last date of the discount period.

15th of June is the last date of credit period

$1600

Step-by-step explanation:

The first question say :

What is the last date of the discount period and last date of credit period?

Initially, EOM is an acronym meaning End of Month

Now. 2/15 indicates 2% discount of the amount to be paid must be included in the payment within 15 days after the end of the month in which invoice is issued.

The last date of the discount period

In order for the company to be eligible for the discount, the company must be willing to pay the invoice within the stipulated time -frame of 15 days from the date the invoice is being issued. So from 11th of May , 15 days after will be May 26th . Thus 26th of May is the last date of the discount period.

The last date of credit period

The last date of the credit period will be 15 days after the end of the Month. The present month is May, so 15 days after the month of May falls at June 15. Thus, 15th of June is the last date of credit period

The second part of the question says:

• If invoice is paid on June 12, how much would the company pay? (Round your answers to the nearest hundredth)

Here , there are two things applied;

The date of the discount period has been passed away (i.e May 26th) but the invoice is being paid on June 12
The payment is done before the last date of credit period.

Thus, the company needs to pay the full amount of $1618 since the date of discount period has passed away.

Now to the nearest hundredth , we have = $1600
