Which data set is the most spread from it's mean?
laila [671]

Answer

C. 49, 17, 4, 18

Step by step explanation

Here mean of all the data set is 88

To find the most spread of data, we need to find the range.

range of set A = The highest value - the lowest value = 36-6 = 30

Range of set B = 30-15 = 15

Range of set C = 49-4 = 45

Range of set D = 30-14= 16

Here the highest range is in Set C.

Therefore, answer is C. 49, 17, 4, 18

-6x + 7 = 8x + A

let x = -4
-6(-4) + 7 = 8(-4) + A
24 + 7      = -32 + A
31 + 32    = -32 + 32 + A
63            = 0 + A
A = 63

Show all work to identify the asymptotes and state the end behavior of the function f(x)=5x/x-25
Nina [5.8K]

Using the asymptote concept, it is found that:

  • The vertical asymptote is of x = 25.
  • The horizontal asymptote is of y = 5.
  • Considering the horizontal asymptote, it is found that the end behavior of the function is that it tends to y = 5 to the left and to the right of the graph.

<h3>What are the asymptotes of a function f(x)?</h3>

  • The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.
  • The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.

In this problem, the function is:

f(x) = \frac{5x}{x - 25}

Considering the denominator, the vertical asymptote is:

x - 25 = 0 -> x = 25.

The horizontal asymptote is found as follows:

y = \lim_{x \rightarrow \infty} f(x) = \lim_{x \rightarrow \infty} \frac{5x}{x - 25} = \lim_{x \rightarrow \infty} \frac{5x}{x} = \lim_{x \rightarrow \infty} 5 = 5

Hence the end behavior of the function is that it tends to y = 5 to the left and to the right of the graph.
