Ella conducted a survey to find out the amount of time high schoolers spend surfing the Internet. From the data collected, the range of time spent was 1 hour. What does this range say about the data? A. All the students surveyed spend exactly 1 hour surfing the Internet.
B. All the students surveyed spend an average of 1 hour surfing the Internet.
C. The difference between the greatest amount of time and the least amount of time spent surfing the Internet is 1 hour.
D. The quotient between the greatest amount of time and the least amount of time spent surfing the Internet is 1 hour.

Answers

Answer 1

Answer: The answer is C.

Because we do not have any tables graphs etc., we can only use the fact that the range is 1

The definition of range is the difference between the largest amount and the smallest amount. In equation form, it should look like this: $Largest-Smallest$

Now lets move to the answer choices:

Answer A. is wrong
If everyone surfed for exactly an hour, the largest amount of time would be 1 hour and the smallest amount of time would also be 1 hour. Put this into the equation and the range would be 0 which is contradicted from the data present

Answer B. is wrong because the range is not the average, the mean is the average. We are looking for the range, not the mean so Answer B. is incorrect.

Answer C. is correct. The range is the difference between the largest and the smallest. In this answer, it tells us that the range is the difference between the greatest amount of time and the least amount of time spent surfing the Internet is 1 hour. This follows the term of "Range" and therefore, Answer C. is correct.

Answer D. is incorrect because the range does not have anything to do with quotients.(By the way, a quotient is the result of dividing a dividend with a divisor.) The range is only obtainable with subtraction, not division, so answer D. is incorrect.

Answers

mostly collect like terms
use associative property which is
(a+b)+c=a+(b+c)
also -a+b-c=(-a)+(b)+(-c) so you can move them around
and remember that:
you just use a general rule
x+x=2x
x^2+x^2=2x^2
3xy4xy=7xy
3x+4x^2=3x+4x^2
youcan only add like terms( like terms are terms that are same name like xor y are differnt, and like terms have same power exg x^2 and x^3 andx^1/2 and such

linda wants to but a cell phone. she has looked at two phones. phone a normally cost $175, but she can a 5% discount. phone b normally cost $200, but she can get a 20% discount. Part a how much is the discount for each phone part b what is the price of each phone after the discount part c which discounted phone cost less? linda will have to pay 6% sales tax on whichever phone she buys. does this change which phone cost less?

Answers

Part A:
Phone A has a $8.75 discount
$175*0.05=$8.75

Phone B has a $40.00 discount
$200*0.20=$40

Part B:

Phone A is $166.25
$175-$8.75=$166.25

Phone B is $160.00
$200-$40=$160

Part C:
Phone B costs less after the discount

Part D:
No, sales tax is applied to the discounted/final price, so both prices will increase by 6%. Phone B will still be cheaper.

If your pencil is 20 cm long how many millimeters is it

Answers

For this, you have to know the unit conversions. For metric, this is somewhat easier to remember. cm = centimeters. centi means 100th. One way to remember this one is that a cent is 1/100th of a dollar. So also is a centimeter 1/100th of a meter. A millimeter is 1/1000th of a meter. so a centimeter is 10 millimeters.
$(20)/(1) (cm)/(1) * (10)/(1)(millimeters)/(cm) = 200 millimeters$

Therefore the solution is 200 millimeters.

Tina pet sits to earn extra money. She charges a flat service fee of $20, plus $20 per day. If one of her customers spent less than $80, which of the following inequalities could be used to solve for x, the number of days the customer paid for pet sitting?$20x + $20 < $80
$20x < $80
$20x - $20 < $80
$20x < $100

Answers

The formula for the total amount costumers pay is 20x+20 because 20* the number of days is 20x and then you have to add the 20 dollars for the service fee. The costumer paid less than 80 dollars so 20x+20, which is what the costumer paid, is less than 80. The answer is $20x+$20<$80.
