Consider the following data set:
20, 22, 31, 37, 39, 40
How would the range be affected if the data point 28 was added to the data set?
The range would decrease by 0.5. Tom
The range would decrease by 3.
The range would increase by 8.
There would be no effect on the range.

There would be no effect on the range.

Step-by-step explanation:

b) 36

step-by-step explanation:

18 times 2 is 36

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!
