First blank: not random Because he sent it to the top 5 students. Not random students throughout the grade.
second blank: I would guess not valid because it was not a random sample.
Answer: The function that models the distance they drive is
f(x) = 50x + 20 where x is the time in hours
reasonable domain: 0 ≤ x ≤ 3
Step-by-step explanation:
examples:
95 = 50(1.5) + 20 After driving another hour and a half, they will have driven a total of 95 miles.
120 = 50(2) + 20 This means that after 2 more hours they will reach their destination.
There is a little ambiguity in the question. The function could be written as if they are starting out. f(x) = 50t
20 = 50(.4) At 50 mph it took .4 hours to go 20 miles.
120 = 5(2.4) The whole trip took 2.4 hours.
Answer:
hi, im not 100% sure but i think this is false.
Step-by-step explanation:
Based on the table given on the punch recipe, the correct answers are:
- 48 cups.
- 48 cups.
- 8
- 8 cups of frozen strawberry.
<h3>What does the table on the punch recipe show?</h3>
3 gallons of punch in cups is:
= 16 cups per gallon x 3 gallons
= 48 cups
The amount that Chandra should multiply each ingredient by is:
= 48 cups / 6 cups per recipe
= 8
The number of cups of frozen strawberries needed is:
= 8 x 1
= 8 cups
