5.4
5
2.6

question 5(multiple choice worth 4 points)

(08.02)evan collected data about the amount of time each student in his math class spends studying. if the range of these data is 2, what does this reveal about the data?

all the students in his math class spend exactly 2 hours studying.
all the students in his math class spend an average of 2 hours studying.
the smallest and largest data values are 2 units away from each other.
the middle data value for time spent studying by all students in his class is 2 hours.

The first question of the answer is d (2.6)

Step-by-step explanation:because, 4.5 x 3 = 13.5, 0.5 x 2 = 1,  1.5 x 2 = 3, and 2.5 x 2 = 5 and I add 13.5 + 3.5 +  1 + 5 + 3 and then i divid 26 and 10 and I got 2.6 in total im not lying.

The answer would be 2.6

Step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
