Two matrices are the same if the entries of the two matrices in the same row and column are the equal.
For this equation to hold, we need
5x - 8 = 2
5x = 10
x = 2
Each friend gets two each
Answer:
Option B is correct, i.e. 30 ways.
Step-by-step explanation:
Given that there are 6 runners at a competition. So it means n = 6.
It says 2 medals are awarded for first and second place. So it means r = 2.
Each medal is different, it means the order matters here. It is the case of Permutations, so we will use nPr formula.
Total number of ways = 6P2 = 6x5 = 30.
Hence, option B is correct, i.e. 30 ways.
Answer:
Since the total number on a spinner is 8 and there are 2 of them we get 8 + 8=16 and the blue one has 1 and they are 2 we get 1+1=2.probability=desired chances/total chances =2/16
Step-by-step explanation:
2km/hr is the answer to the question
