Answer:

D

Step-by-step explanation:

Simply put, domain means the x value and range means the y value.

<em><u>The question asks for the corresponding range (y-value) for domain (x-value) of 2. </u></em>

Looking at the graph, x value of 2 corresponds to y value of 4. So the answer is 4.

Correct answer is D

Answer:

The choice D is correct.

Step-by-step explanation:

We have given graph.

We have to find the range value corresponds to the domain value 2.

The domain is the value of x, and range is the value of y.

In the,graph, the horizontal  line represents the x-axis and vertical line represents  the y -axis.

so when we see the graph the domain value x=2 corresponds to range vale

y = 4 .

So, choice D is correct.

Given the function f(x) = 4x - 2, explain and show how to find the average rate of change between x = 2 and x = 4.
zalisa [80]

Answer:

The average rate of change between x = 2 and x = 4 is of 4.

Step-by-step explanation:

Average rate of change:

The average rate of change of a function f(x) in an interval [a,b] is given by:

A = \frac{f(b)-f(a)}{b-a}

In this question:

f(x) = 4x - 2, b = 4, a = 2

Thus:

f(b) = f(4) = 4(4) - 2 = 16 - 2 = 14

f(a) = f(2) = 4(2) - 2 = 8 - 2 = 6

Average rate of change:

A = \frac{f(b)-f(a)}{b-a}

A = \frac{14-6}{4-2}

A = \frac{8}{2}

A = 4

The average rate of change between x = 2 and x = 4 is of 4.

What are the possible values of x for the following functions?
stiks02 [169]
What can a denominator never be?

0

so, we need to figure what x can't be... the only way to multiply 2 things together to get 0 is if one or both are zero.

so, what x values make our denominator 0?

to figure this out, we need to set (x-1)(x-2)=0

now we split and solve.

x - 1 = 0 \\ x - 2 = 0
so when x is 1 or 2 the function doesnt make sense.

but, x can be every other number and it does, so the answer is

Suppose a simple random sample of size nequals49 is obtained from a population with mu equals 78 and sigma equals 28.
VLD [36.1K]

Answer:

0.0735,0.0179,0.7026

Step-by-step explanation:

Given that a simple random sample of size nequals 49 is obtained from a population with mu equals 78 and sigma equals 28.

Sample size = 49

Population mean = 78

Population std deviation = 28

Std error of sample mean = \frac{\sigma}{\sqrt{n} } \\=4

a) \bar x: N(78, 4)

b) P(\bar x >83.8)\\=0.0735

(by converting to Z and finding value from Z table)

c) P (x overbar less than or equals 69.6 )​

=P(\bar x \leq 69.6)\\=0.0179

d) P (75.8 less than x overbar less than 88 )

=P(75.8
