What is the mode of the data values: 54,78,26,36,26

Mode: the numbers that occurs the most in a set of data.

Although it's optional, I prefer to list the numbers in order from least to greatest because it makes it easier to see what number occurs the most.

Least to greatest - 26,26,36,54,78

The mode of this set of data is 26. The number 26 occurs twice and no other number occurs more than once in that set of data.

The mode for this set of numbers is 26.

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'.
