Answer:
Mean = 18.8
Step-by-step explanation:
Mean = (Sum of all values)/(Number of values)
Mean = (12 + 15 + 18 + 23 + 26)/5
Mean = 94/5
Mean = 18.8
The hypotenuse is equal to the square of the other two sides. The length of AC from the diagram is 21.9feet
<h3>Application of pythagoras theorem</h3>
The theorem states that the square of the hypotenuse is equal to the square of the other two sides
Given the following
Hypotenuse = 26 feet = CD
Base side = AD = 14ft
Required
Length AC
Use the theorem
26^2 = 14^2 + AC^2
AC^2 = 676 - 196
AC^2 = 480
AC = 21.9feet
Hence the length of AC from the diagram is 21.9feet

Yes. A regular polygon is equilateral and equiangular; an equilateral triangle is both equilateral and equiangular, so a triangle can be a regular polygon.

the formula for volume is PI x Raadius squared x Highth
Answer:
For the sum of the digits of Michelle’s father to drop to 1/3 of its’ former value, the second digit must go from 9 to 0, in one year.
Thus, if he is 39 this year, the sum of the digits of his age will be 12. Next year, when the sum of the digits would be 4+0, or 4, then the digits of his age would be 1/3rd of their former value.
Therefore, he is 39, and will be 40 next year
