Greta collected data about the amount of time each student in her geography class spends studying. if the range of these data is 3, what does this reveal about the data?

a. all the students in her geography class spend exactly 3 hours studying.
b. the smallest and largest data values are 3 units away from each other.
c. all the students in her geography class spend an average of 3 hours studying.
d. he middle data value for time spent studying by all students in her class is 3 hours.

B. The smallest and largest data values are 3 units away from each other.

Step-by-step explanation:

The range of a data set is defined as the subtraction of the smallest value in the data set to the largest value in the data set. Then, the smallest amount of time is 3 units away from the largest amount of time.

step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
