Which of the following is not a commonly used practice? choose the correct answer below.a.the distribution of sample means gets closer to a normal distribution as the sample size n gets larger.b.if the original population is not normally distributed and ngreater than30,the distribution of the sample means can be approximated reasonably well by a normal distribution.c.if the distribution of the sample means is normally distributed, and ngreater than30,then the population distribution is normally distributed.d.if the original population is normally distributed, then for any sample size n, the sample means will be normally distributed.

Hello there!

we have the point (3,2) which means that x = 3 and y = 2

The systems of equations are:

Y <  - 2

Y ≥ (2/3)x - 4

and

Y > - 2

Y ≤ (2/3)x - 4

The points were the systems are true in the white areas, the colored areas are the excluded ones.

Now we need to put our point in both systems and see if the point is a solution or not,

In the first one, you can see that y needs to be less than -2, and in out point y is equal to 2, then the point (3,2) cant is a solution of the first system.

let's see the second system:

Y > - 2

Y ≤ (2/3)x - 4

valuate it in the point (3,2)

2 > -2

2 ≤ (2/3)*3 - 4 = - 2

this is also false.

Then the point (3,2) is not a solution for neither system, and you can see it in the graphs, in the first graph the point (3,2) is in the black area, and in the second one is in the red area.
