Given the matrix
- A matrix is singular if its determinent is zero.
so solving the matrix B by taking its determinant to get the value a
as according to determinant formula
Therefore, the value of a=4
333.0 if you plug into the formula, 4/3pi r^3
Answer:
If there is an even number of numbers, the median is the average of the two numbers in the middle.
Step-by-step explanation:
To find the median of any set of numbers, put them in order from smallest to greatest. If a number occurs more than once, list it more than once. The number in the middle is the median. If there is an even number of numbers, the median is the average of the two numbers in the middle. For your first example, we line them up: 3, 6, 6.
Answer:
51
Step-by-step explanation:
Given parameters:
Number of heads = 30 heads
Number of legs = 84 legs
Unknown:
Number of chickens and pigs = ?
Solution:
Since a chicken has one head, the number of chicken is the same as the number of heads;
Number of chicken = 30
A pig has 4 legs,
Number of pigs = 
= 21pigs
Total number of pigs and chickens = 30chickens + 21 pigs = 51
18 +2 = 20
s = 20
