The spreadsheet shows the length of 3 movies in each of 3 categories. choose the formula that could be used in cell b2.

Option 'B' is correct.

Step-by-step explanation:

Since we have given that

There are three types of movies :

1) Animated

2) Drama

3) Action.

Since At B2 cell, there is Animated movie.

Since we have given the average of three animated movies = 73

Length of 1 movie is at B2 cell.

Length of 2nd movie = 63

Length of 3 rd movie = 84

As we know the formula for "average":

Hence, Option 'B' is correct.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
