The box plots represent the distributions of typing speeds of students before and after a computer-programming course. Which statement is true about the variability of the distributions?

The interquartile range of the typing speeds after the course is greater than the interquartile range of the speeds before the course.
The interquartile ranges of the two distributions are the same.
The range of the speeds after the course is smaller than the range of the speeds before the course.
The ranges of the two distributions are the same.

C on edge

Step-by-step explanation:

the range of the speeds after the course is smaller than the range of the speeds before the course.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
