What is the graph of the function rule?<br><br> y = 3x - 2<br><br> Choose from the pictures
bulgar [2K]

we have

y=3x-2

we know that

this is the equation of a line, to identify which is the graph we will proceed to determine the points of intersection with the coordinate axes

1) <u>Find the y-intercept</u>

the y-intercept is when the value of x is equal to zero

For x=0

find the value of y

y=3*0-2

y=-2

2) <u>Find the x-intercept </u>

the x-intercept is when the value of y is equal to zero

For y=0

find the value of x

0=3x-2

x=(2/3)

therefore

the answer is the option B ( see the attached figure)

g Make a decision about the given claim. Use only the rare event​ rule, and make subjective estimates to determine whether event
vagabundo [1.1K]

Answer:

There is not sufficient evidence to support the claim.

Step-by-step explanation:

The claim to be tested is:

The mean respiration rate (in breaths per minute) of students in a large statistics class is less than 32.

To test this claim the hypothesis can be defined as follows:

<em>H₀</em>: The mean respiration rate of students is 32, i.e. <em>μ</em> = 32.

<em>Hₐ</em>: The mean respiration rate of students is less than 32, i.e. <em>μ</em> < 32.

The sample mean  respiration rate of students is 31.3.

According to the claim the sample mean is less than 32.

The sample mean value is not unusual if the claim is true, and the sample mean value is also not unusual if the claim is false.

Thus, there is not sufficient evidence to support the claim.
