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.

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
