Does this set of ordered pairs represent a function? Why or why not ?

Answer:

C. Yes, because every x-value corresponds to exactly one y-value

Step-by-step explanation:

We are asked to find whether the given ordered pairs represent a function or not.

$\{(-1,5),(0,-3),(2,7)(4,0),(7,5)\}$

We know that a relation is a function, when each input of x value gives exactly one output of y-value.

In a function two or more x-coordinates can give same y-value, but one x-value cannot give two y-values.

We can see that in our given set each x-value corresponds to exactly one y-value, therefore, the given set represents a function.

Answer:

The answer is below

Step-by-step explanation:

A transformation of a point is the movement of an point from an initial position to a new position. If an object is transformed, all the point of an object is transformed. Two figures are said to be congruent if they have the same shape and the measure of each of their sides are the same.

An object is congruent to another object if the object can be mapped to the other object when transformed.

What are two possible transformations that together could have been used to create the red figure from the blue figure?

attashe74 [19]

Id say 2 and 3 .  It has to reflect off of the Y axis to look like the red figure. Other than that I can't help.

A survey of 35 people was conducted to compare their self-reported height to their actual height. The difference between reporte

Over [174]

Answer:

The test statistic is t = 3.36.

Step-by-step explanation:

You're testing the claim that the mean difference is greater than 0.7.

At the null hypothesis, we test if the mean difference is of 0.7 or less, that is:

$H_0: \mu \leq 0.7$

At the alternate hypothesis, we test if the mean difference is greater than 0.7, that is:

$H_1: \mu > 0.7$

The test statistic is:

$t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}$

In which X is the sample mean, $\mu$ is the value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.

0.7 is tested at the null hypothesis:

This means that $\mu = 0.7$

A survey of 35 people was conducted to compare their self-reported height to their actual height.

This means that $n = 35$

From the sample, the mean difference was 0.95, with a standard deviation of 0.44.

This means that $X = 0.95, s = 0.44$

Calculate the test statistic

$t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}$

$t = \frac{0.95 - 0.7}{\frac{0.44}{\sqrt{35}}}$

$t = 3.36$

The test statistic is t = 3.36.

Optimization problem: what are the dimensions of the lightest open-top right circularcylindrical can that will hold a volume of

vivado [14]

So Volume of cylinder is pi*r^2*h = 1,000

Then lightest one means you have the smallest surface area. Which is one base and then the area of the surface. SA = pi*r^2 + 2pi*r*h

So now you have 2 equations, so:

h = 1,000/(pi*r^2)
So then SA = pi*r^2 + 2pi*r*(1,000/(pi*r^2) = pi*r^2 + 2,000/r

Derivative of SA is then 2pi*r -2,000/r^2. Set to 0

2pi*r-2,000/r^2 =0 --> 2pi*r^3 = 2,000 --> r^3 = 1,000/pi --> r = 10/pi^(1/3)

Now go back to the volume function: pi*r^2*h =1,000 --> 1,000/(pi*100/pi^(2/3)) = h
h = 10 / pi^(1/3)
