Answer:
Option A - 10
Step-by-step explanation:
Given : There are 3 red chips and 2 blue chips. If they form a certain color pattern when arranged in a row, for example RBRRB.
To find : How many color patterns are possible?
Solution :
Total number of chips = 5
So, 5 chips can be arranged in 5! ways.
There are 3 red chips and 2 blue chips.
So, choosing 3 red chips in 3! ways
and choosing 2 blue chips in 2! ways.
As changing the places of similar chip will not create new pattern.
The total pattern is given by,
Therefore, color patterns are possible are 10.
Option A is correct.
Answer:
200X = Y
Step-by-step explanation:
Since the insect in question can flap its wings 200 times per second, the equation that represents how many times it flaps its wings according to the time of flight is the following:
200X = Y
Thus, 200 is the number of times per second it flaps its wings, while X is the number of seconds in question. In turn, Y is the number of times it flaps its wings in the given time.
For example, if the insect were to fly for 5 seconds, the equation would work as follows:
200 x 5 = Y
1000 = Y
A natural number is a counting number, it is like 1,2,3,4,5, etc
an integer is a natural number and also negative numbers and 0
so like -3,-2,-1,0,1,2,3
a natural number is always an integer
