Set up an equation with x as the variable for the missing number

(28+32+21+22+x)/5 = 24.4

multiply both sides by 5

28+32+21+22+x = 5(24.4)

simplify (add and multiply)

103+x = 122

subtract 103 from both sides

x = 122-103

simplify

x = 19

Hair colors are an example of which type of data?
kotykmax [81]

Answer:

Nominal data are used to label variables without any quantitative value. Common examples include male/female (albeit somewhat outdated), hair color, nationalities, names of people, and so on. In plain English: basically, they're labels (and nominal comes from "name" to help you remember). You have brown hair (or brown eyes).

Which of the following is a area of the special trepezoid if ab=19,cd=19 and the height is 14
tankabanditka [31]

As, Opposite side of Special trapezoid is equal.So, it will be a Parallelogram.

ab=c d= 19 units

Height of Trapezoid = 14 units

Area of Trapezoid =  \frac{1}{2} \times {\text{Sum of parallel sides}} \times {\text{Perpendicular Distance between them}}

  =\frac{1}{2}\times (19+19) \times 14\\\\ =\frac{1}{2} \times 38 \times 14\\\\ = 19 \times 14\\\\= 266

So, Area of Trapezoid = 266 square units

You, can use the formula for finding the area of parallelogram,which is = Base on which perpendicular is drawn × Length of Altitude

= 19 × 14

= 266 square units
