Brianna surveyed a representative sample of students at her school to collect data about the numbers of Internet-compatible devices they own. Brianna wants to know how many Internet-compatible devices are owned, on average, by people in her town. Can she use her sample data to form a valid inference about the town? Use the drop-down menus to explain your answer. Brianna can/cannot use her sample data to form a valid inference about the town because her school does/does not represent her town’s entire population.

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!

c

step-by-step explanation:

i think because what else can be a sample of every member

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

im guessing (23,14). hope this : )
