Using a Laplace expansion along the first column, we have
The determinant of a 2x2 matrix is trivial,
So we have
The mean is the average value of numbers given in the series
The median is the middle value of the given series
The mode is the number that is appears more than any other number given in the series
Step-by-step explanation:
The given series is 31,1,27,23,15,27,25,18,22 (totally 9 numbers)
let us change them in a ascending order like 1,15,18,22,23,25,27,27,31
Mean = 21
Median = middle value of the series 1,15,18,22,23,25,27,27,31
23 is the median
Mode = 27 ( it appears in two times 1,15,18,22,23,25,27,27,31)
final answer is
Mean = 21
Median = 23 and
Mode = 27
Answer:
Step-by-step explanation:
a). By applying Pythagoras theorem in right triangle ABC,
AC² = AB² + BC²
20² = 16² + BC²
BC =
= 12
Therefore, another leg of the triangular base = 12 cm
Area of the triangular base ABC =
=
= 96 cm²
Volume of a triangular prism = Area of the triangular base × height
960 = 96 × b
b = 10 cm
b). Area of the triangle ABC = 96 cm²
