Answer:

Switch x and y, and solve for y

f^{-1}(x) =\frac{(x -4)^3}{8}

Step-by-step explanation:

Given

f(x) = 3\sqrt{8x} + 4

Required

Complete the steps to determine the inverse function

Solving (a): Complete the blanks

Switch x and y, and solve for y

Solving (b): Determine the inverse function

f(x) = \sqrt[3]{8x} + 4

Replace f(x) with y

y = \sqrt[3]{8x} + 4

Switch x and y

x = \sqrt[3]{8y} + 4

<u>Now, we solve for y</u>

Subtract 4 from both sides

x -4= \sqrt[3]{8y} + 4-4

x -4= \sqrt[3]{8y}

Take cube roots of both sides

(x -4)^3= 8y

Divide both sides by 8

\frac{(x -4)^3}{8} = y

So, we have:

y =\frac{(x -4)^3}{8}

Hence, the inverse function is:

f^{-1}(x) =\frac{(x -4)^3}{8}

Which of the following best describes a cylinder?
alexandr1967 [171]
Hey there!

The shape being described in letter A is a prism. A prism has two polygonal shapes on either end that can be any shape consisting of three or more sides. This won't be your answer, since cylinders have circular bases on either side. 

The shape being described in letter B is a cylinder. Not sure why they needed to throw in the plane part, but this is the only answer that describes the bases as being circular (or, as they put it, discs). 

The shape being described in letter C is a pyramid. If a shape has a polygonal base and meets at a point at the other end, it will be a pyramid. Obviously, a pyramid only has one end, meaning that this isn't your answer. 

The shape being described in letter D is a cone. Again, if a shape has a base and meets at a point, it will be a pyramid. However, in the case of a cone, the base will be circular and the other side will meet at a point. The entire shape will be rounded where a pyramid would have edges. Again, not your answer. 

Your answer will be B. Hope this helped you out! :-)

Roger claims that the two statistics most likely to change greatly when an outlier is added to a small data set are the mean and
Leni [432]

Answer:

No, the Roger’s claim is not correct.

Step-by-step explanation:

We are given that Roger claims that the two statistics most likely to change greatly when an outlier is added to a small data set are the mean and the median.

This statement by Roger is incorrect because the median is unaffected by the outlier value and only the mean value gets affected by the outlier value.

As the median represents the middlemost value of our dataset, so any value which is an outlier will be either at the start or at the end will not the median value. So, the median will not likely change when an outlier is added to a small data set.

Now, the mean is the average of all the data set values, that is the sum of all the observations divided by the number of observations. The mean will get affected by the outlier value because it take into account each and every value of the data set.

Hence, the mean will likely to change greatly when an outlier is added to a small data set.
