What is the solution set of {x | x < -5} ∩ {x | x > 5}?

Mathematics
1 answer:
Pavlova-9 [17]3 years ago
8 0

The first part of the set tells us that x is less than -5.

The second part tells us that x is greater than 5.

The intersection sign in the middle tells us to find "common" item in the first part and second part.

<u><em>Is there any number both greater than 5 and less than -5? No!</em></u>

So our solution doesn't exist and is the empty set.


ANSWER: The empty set

Please help and thank you
kondaur [170]

Answer:

Step-by-step explanation:

Let's see how well I can explain this. \frac{\pi}{6} is the same as a 30 degree angle which is in quadrant 1. If you picture the unit circle, right in the center of it is the origin. If you draw a straight line from 30 degrees and through the center (the origin), you will automatically "connect" with the reference angle of 30 (this is true for ALL angles on the unit circle). This puts us in quadrant 3. In quadrant 3, x is negative and so is y. So the terminal point of the reference angle for 30 degrees has the same exact values, but both of them are negative (again, because both x and y are negative in quadrant 3). I can't see your choices but the one you want looks like this:

(-\frac{\sqrt{3} }{2},-\frac{1}{2})

Increasing the sample size while keeping the same confidence level has what effect on the margin of error? A. Increases the marg
DiKsa [7]

Answer:

C. Decreases the margin of error and hence increases the precision

Step-by-step explanation:

If we select a sample by Simple Random Sampling in a population of “infinite” size (a population so large that we do not know its size exactly), then the margin of error is given by

\bf E=\frac{ZS}{\sqrt{n}}

where  

<em>Z = The Z-score corresponding to the confidence level </em>

<em>S = The estimated standard deviation of the population </em>

<em>n = the size of the sample. </em>

As we can see, since n is in the denominator of the fraction and the numerator is kept constant, the larger the sample size the smaller the margin of error, so the correct choice is:

C. Decreases the margin of error and hence increases the precision
