we can conclude that the range is:

(0, 5), (-16, -1), (12, 4)

Which is the first option (counting from the top).

<h3>How to find the range?</h3>

When we have a relation:

x⇒f(x) = y

We define the domain as the set of possible inputs, and the range as the set of possible outputs.

In this case, we know that the domain is:

(0, 5), (8, -1), (-6, 4)

And the transformation is:

f(x, y) = (-2x, y)

So, if we apply that to each one of the pairs in the domain, we will get:

f(0, 5) = (-2*0, 5) = (0, 5)

f(8, -1) = (-2*8, - 1) = (-16, -1)

f(-6, 4) = (-2*-6, 4) = (12, 4)

Then we can conclude that the range is:

(0, 5), (-16, -1), (12, 4)

Which is the first option (counting from the top).

Answer:

a

$z-score = 1.57$

b

$z-score_s = -3.36$

Step-by-step explanation:

From the question we are told that

The sample size is n = 103

The sample mean of sag is $\= x_1 = 353$

The sample mean of swells is $\= x_2 = 184$

The standard deviation of sag is $s_1 = 30$

The standard deviation of swells is $s_2 = 25$

The number of swell for a randomly selected transformer is k = 100

The number of sag for a randomly selected transformer is c = 400

Generally the z-score for the number of swells is mathematically represented as

$z-score_s = \frac{ k - \= x_2}{s_2}$

=> $z-score_s = \frac{ 100- 184}{25}$

=> $z-score_s = -3.36$

Generally the z-score for the number of sags is mathematically represented as

$z-score = \frac{ c - \= x_1}{s_1}$

$z-score = \frac{ 400 - 353}{30}$

$z-score = 1.57$
