A store finds that the number of shirts sold increases each week. In the first week, only 15 shirts were sold. In the next week,

nikklg [1K]

Answer:

$a_n=8+7n$

Step-by-step explanation:

No. of T-Shirts sold in first week = 15

No. of T-Shirts sold in second week = 22

No. of T-Shirts sold in third week = 29

The number of shirts sold each week represents an arithmetic sequence.

15,22,29,....

So, a = first term = 15

d = common difference = 22-15= 29-22= 7

Formula of nth term : $a_n=a+(n-1)d$

a is the first term

d is the common difference

n is the number of term

Now substitute the values in the formula :

$a_n=15+(n-1)7$

$a_n=15+7n-7$

$a_n=8+7n$

Where n is the number of weeks

Hence the explicit rule for the arithmetic sequence that defines the number of shirts sold in week n is $a_n=8+7n$

A box has three cards numbered 1, 2, and 3

Igoryamba

Answer:

{1A, 1B, 1C, 2A, 2B, 2C, 3A, 3B, 3C}

{1C, 2C, 3C}

Step-by-step explanation:

First is all possibilities. Let's do it one step at a time. The first step is the number, what are all the numbers that can be chosen? 1 2 and 3. then, when you pick1, what are all the letters that can be chosen? A B and C. Do this for 2 and 3 and you get all possibilities.

{1A, 1B, 1C, 2A, 2B, 2C, 3A, 3B, 3C}

When you have steps like this you can multiply the number of results to get the total number of possibilities as well. Step one has 3 results, step 2 has 3 results, that means there are 3*3 total, which is 9. Do be careful it matches this kind of setup, where the step 2 is the same for all step 1s. So if instead if you got 1 for step 1 you picked from a bag with 3 things, then for 2 you picked from a different bag with a different number, that multiplication trick wouldn't work.

Now just pick throught he sample space to find all with C. There are three, {1C, 2C, 3C}
