The answer is unreasonable because the value of x is between 2 and 3.The error is : she did not introducing logs in solving the equation.
Step-by-step explanation:
The question is
Here answers is unreasonable because, she can test with powers of seven like;
7²=49
7³=343
So this means the value of x lies between 2 and 3, so here answer 11.71 is unreasonable

Since the intersection is - by definition - common to both sets, we can work out the number of people that use only the fitness suite or the swimming pool.
We know that 57 people use the fitness suite, but 36 of those are already counted in the intersection. So, 57-36=21 people use only the fitness suite.
The same goes for the swimming pool: 49-36=13 people use only the swimming pool.
So, we have:
- 21 people using fitness suite only
- 13 people using swimmng pool only
- 36 people using both
This sums to 21+13+36=70 people. We deduce that 30 people don't use any of the features.
