Your question wasn't posted clearly.
It would be difficult to help you.
It's all one big mess.
Was it supposed to be two or three separate expressions?
Your answer would be the last option, c = √(E/m).
We can see this when we rearrange the equation, as:
E = mc²
÷ m
E/m = c²
√
√(E/m) = c
So you got all the steps in rearranging correct :)
I hope this helps!
Answer:
43
Step-by-step explanation:
Square root of 9 is 3
Square root of 16 is 4
Square root of 25 is 5
Square root of 43 is not a whole number.
A) Since there are four multiple choice questions Which has one correct answer. The probability of choosing a correct answer is
The probability of choosing wrong answer is
Using the multiplication rule
b) If you guess answers to three of the questions, then the possibilities of getting one correct answer are:
Either the first two are wrong and the third one is correct. This will give the arrangement;
Or the first is wrong the second one is correct and the last one is wrong. This will give the arrangement,
Or the first one is correct and the last two are wrong. This will give the arrangement,
.
c) The probability of getting one correct answer is either the first one is correct or second is correct or third is correct.
