Each week your science teacher gives a fifteen-point quiz. your current scores are shown in the table. what is your mean quiz score?

15 11 10 11 14 10 15 10 12

The mean should be 12.

Step-by-step explanation:

To find the mean of a range of numbers, you must simply add all of the numbers together and divide by how many numbers there are in the group.

In this case, I did 15+11+10+11+14+10+15+10+12, which came to be 108. I divided that by 9, since there are nine numbers, which gave me 12.

Hopefully this helps!

answer: are you

step-by-step explanation:

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!
