The median of a list of whole numbers must be a whole number.

a. true
b. false

Option B. False

Step-by-step explanation:

If we take set of whole numbers as 1, 2, 3, 4, 5, 6.

Then the median of this set will be mean of two whole numbers which are in center.

Median = (3 + 4)/2 = 7/2 = 3.5

which is not a whole number.

Therefore the given statement that median of a list of whole numbers must be a whole number is False.

Answer is False.

answer: c is correct, a regular pentagon

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'.
