A square has sides measuring 3 feet. If the sides of a square are doubled, will the area also double? Explain
Kryger [21]
Hello!

Let's find the area and see!

A = s^2

A = 3^2

A = 6 ft^2

Now, if you double 3, you get 6. 3 × 2 = 6 Find the area:

A = 6^6

A = 36 ft^2

ANSWER:

No, the area will not be doubled. The area was 9 ft^2 when the sides were 3 feet long. If you double 9, you get 18, since 9 × 2 = 18.

36 is not the double of 9, so no, the area is not double.

love history [14]

Answer:

The correct option is (C).

Step-by-step explanation:

A null hypothesis is a sort of hypothesis used in statistics that intends that no statistical significance exists in a set of given observations.  

It is a hypothesis of no difference.

It is typically the hypothesis a scientist or experimenter will attempt to refute or discard. It is denoted by H₀.

Whereas the alternative hypothesis is a contradicting statement tot he null hypothesis. It is denoted by Hₐ.

In this case we need to test whether the average age of online consumers has increased or not.

From previous data we know that the average age of online consumers a few years ago was 24.1 years.

A one-sample mean test can be used to determine whether the mean age has increased or not.

The hypothesis for the test can be defined as follows:

<em>H₀</em>: The average age of online consumers is 24.1 years, i.e. <em>μ</em> = 24.1.

<em>Hₐ</em>: The average age of online consumers is more than 24.1 years, i.e. <em>μ</em> > 24.1.

Thus, the correct option is (C).

Which shows the equation of the line containing the points (-2, 6) and having a slope of 3 in intercept-form?
puteri [66]
We know that the slope-intercept form of an equation is represented by:

y = mx + b

Where m is the slope, b is the y-intercept, and x and y pertain to points on the line in the graph.

So the slope of the line is know to be 3, and we are able to plug that into the equation:

y = 3x + b

We also know that the point (-2, 6) is on the line. With this information, we can then plug in the point into the equation to find b:

6 = 3(-2) + b

Then we can solve for b:

6 = -6 + b

b = 12

Knowing that b is 12, we can then rewrite the equation in a more general slope-intercept form that is applicable to any point on that line:

y = 3x + 12

Thus, your answer would be C.
