The cost of a tv dropped from $265 in 2012 to $199 in 2014. Find the average rate(slope) at which the cost has been decreasing?

Mandarinka [93]

It has already been given in the question that the cost of tv has dropped fro $265 in 2012 to $199 in 2014. To find the average rate of decrease in the cost of tv in 2 years we have to subtract the difference in price and then divide it by 2 to get to the actual result that is needed.
Difference in price of tv = (265 - 199) dollars
= 66 dollars
so the difference in price of tv in 2 years is $66
Then
The average rate of decrease in cost of tv = 66/2
= 33
So $33 is the average rate of decrease in the price of tv between the years 2012 and 2014.

1. For each of the following, indicate whether it is a question that involves permutations, combinations, or neither, and then a

krek1111 [17]

Answer:

Step-by-step explanation:

we are given some scenerios and we are to find out the total number of ways after mentioning permutations, combinations, or neither

a. How many ways can a coach choose two co-captains from 16 players in the basketball team?

Combination because both are having same position so order does not matter

16C2 = 120

b. In how many ways can seven questions out of ten be chosen on an examination?

Combinations because order of question does not matter.

10C7 = 10C3 = 120

c. Find the number of ways that 10 women in the finals of the skateboard street competition can finish first, second, and third in the X Games final.

Here order matters. Hence permutation

10P3 = 720

d. A postal zip code contains five digits. How many different zip codes can be made with the digits 0–9? Assume a digit can be repeated.

Here repitition is allowed. So neither permutation nor combination.

No of ways = $10^5$
