Answer:
If x can only have one answer, then the solution is one value. If x can be all real numbers, then the solution is all real numbers. And if x doesn't have an answer then it has no solution.
Step-by-step explanation:
For example:
One value: 7 + x= 10 => x= 3
All real numbers: 0x=0 => x can be all real numbers
No solutions: 7x=6x => no solutions
Answer:


And the best option would be:
4. Minimum: 869.69; maximum: 961.17
Step-by-step explanation:
We can assume that the variable of interst X is distributed with a binomial distribution and we can use the normal approximation.
For this case the mean would be given by:

And the standard deviation would be:

And if we find the limits we got:


And the best option would be:
4. Minimum: 869.69; maximum: 961.17
Answer:
4 and 9
Step-by-step explanation:
here's how it should be:
(36÷4) - (36÷9)
9 - 4
5
