Astudy is being conducted on the amount of gasoline purchased on an average day in town. a random variable is used to identify the amount in gallons. is the variable in this study discrete or continuous? why? 1. it is discrete because the gallons of gasoline are measured in whole numbers. 2.it is continuous because there is no way to determine how many people will purchase gasoline. 3.it is discrete because the study is confined only to gas stations in town. 4.it is continuous because the number of gallons can take on any value over a range of values.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
