Considering the Central Limit Theorem, we have that:

a) The probability cannot be calculated, as the underlying distribution is not normal and the sample size is less than 30.

b) The probability can be calculated, as the sample size is greater than 30.

<h3>What does the Central Limit Theorem state?</h3>

It states that the sampling distribution of sample means of size n is approximately normal has standard deviation s = \frac{\sigma}{\sqrt{n}}, as long as the underlying distribution is normal or the sample size is greater than 30.

In this problem, the underlying distribution is skewed right, that is, not normal, hence:

  • For item a, the probability cannot be calculated, as the underlying distribution is not normal and the sample size is less than 30.
  • For item b, the probability can be calculated, as the sample size is greater than 30.

Find the value of x and y
bagirrra123 [75]
According to google, the red marks mean those two lines are the same length.  If that's the case, we know that x is the angle in both corners of the lower triangle.  We also know that because the angle of a straight line is 180, that the top angle of the bottom triangle is 140, because it's divided into two parts, one of which is 40.  That leaves 140 for the rest.  Now we know that there are 180 degrees in a triangle so x=(180-140)/2 = x=20degrees.
The right angle in the left corner is 90 degrees.  It is divided in two parts, the lower one of which we just found to be 20.  So the other part must by 70deg.
So for the upper angle y, we have 180-70-40= y=70degrees

The slope of a line is 2. The y-intercept of the line is –6. Which statements accurately describe how to graph the function?
Ne4ueva [31]
A because (0,-6) is the y-intercept so you start at the point you know. Then because slope is a rise over run fraction the slope can also be written as 2/1 which is rise 2 over 1.
