Regarding the first question, the scale and the fact that the graph starts at 50 and not at 0 on the vertical axis, shows a deceptive growth trend. Therefore, the creator of this graph wants the reader to conclude that "The car dealership business is expanding very quickly"

In the second question, using wider bars, different colors or an interval of 1 will not make the graphic stop being misleading. Therefore the correct option is the fourth one: Start the y axis at zero and use an interval of 5 or 10. In the attached image the same graphic is shown but with these changes made and the difference is clearly noticed.

In the third question, if The Camera Shop wants to use the measurement of the central tendency that expresses how successful they are in the sale of cameras should consider that the data present high dispersion. For example, in February the value is of 21 and in December the value is of 125. The mean is a sensitive measure to the extreme values, for that reason of all the measures of central tendency cited the mean is the one that gives a higher result and for that may be the ideal to present to management the success of sales:

mean = 63.16

interquartile range = 47.5

mode = 35

median = 59.5

Given the functions f(x)= 1/x−4 +3 and g(x)=1/x+1 +6 .

melomori [17]

ANSWER

The graph shifts 5 units left and 3 units up.

EXPLANATION

The given functions are:

$f(x) = \frac{1}{x - 4} + 3$

and

$g(x) = \frac{1}{x + 1} + 6$

We want to transform f(x) so that, it coincide with the g(x).

The required transformation is

$f(x+5)+3$

Let us see why this works.

$f(x+5)+3 = \frac{1}{x + 5- 4} + 3 + 3$

$f(x+5)+3 = \frac{1}{x + 1} + 6 = g(x)$

The transformation f(x+5)+3 will shift f(x) 5 units left and 3 units up.

The third choice is correct.

Angelina_Jolie [31]

Answer:

$P(X = 0) = 0.027$

$P(X = 1) = 0.189$

$P(X = 2) = 0.441$

$P(X = 3)= 0.343$

Step-by-step explanation:

The probability mass function P(X = x) is the probability that X happens x times.

When n trials happen, for each $x \leq n$ , the probability mass function is given by:

$P(X = x) = pe_{n,x}.p^{x}.(1-p)^{n-x}$

In which p is the probability that the event happens.

$pe_{n,x},$ is the permutation of n elements with x repetitions(when there are multiple events happening(like one passes and two not passing)). It can be calculated by the following formula:
