Answer:

3(x - 2)(x + 4).

Step-by-step explanation:

3x^2 + 6x – 24

= 3(x^2 + 2x - 8)

= 3(x - 2)(x + 4).

The value of the standardized test statistic for this significance test is 1.7265

Standardized test statistic

In statistics, the standardized test statistic means a way for you to compare your results to a “normal” population.

Given,

A city ordinance requires that more than 75% of its residents must agree to the construction of new public buildings (using tax dollars) before any such structures can be built. a proposal has been made to build a new recreational facility in the city, and sponsors of the proposal want to conduct a small survey to see if it would be approved if put to an official vote of all residents. a simple random sample of 150 residents revealed that 123 supported a change (and 27 did not).

Here we need to find the value of the standardized test statistic for this significance test.

While we looking into the given question we have identified the following values,

Random samples = 150

Supported values = 123

Not supported = 23

Aggreged percentage = 75%

So, the null and alternative hypotheses were as follows: H0: p = 0.75 and Ha: p ≠ 0.75.

Then the value of Standardized test statistic is calculated as,

=> (150 - 123) / (75 / √23)

=> 1.7265

HELP ME THIS THE LAST ONE AND THEN I AM DONE PLS HELP BTW I COULDN’T TAP ON THE LINK THAT U GAVE ME I FORGOT UR NAME

Answer:

$\Huge\boxed{V=550}$

Step-by-step explanation:

Hello There!

For this problem we want to split the irregular 3d figure into two regular 3d figures

Two rectangular prisms with the following dimensions

rectangular prism 1

length - 5 feet

width - 12 feet

height - 5 feet

rectangular prism 2

length - 5 feet

width - 5 feet

height - 10 feet (was found by subtract height of rectangular prism 1 (5 feet) from the total height of the irregular figure (15-5=10 so the height of rectangular prism 2 is 10 feet)

Now to find the volume of each individual prism...

So remember the formula for volume of a rectangular prism is

volume = length x width x height

so having the dimensions of each rectangular prism we plug in each value to the formula ( remember we're doing this for each individual rectangular prism)

For rectangular prism 1

V = 12 x 5 x 5

12x5x5=300 so the volume of rectangular prism is 300 cubic feet

For rectangular prism 2

V = 10 x 5 x 5

10x5x5=250 so the volume of rectangular prism is 250 cubic feet

our final step is to add the two volumes together

250 + 300 = 550

so we can conclude that the volume of the rooftop is 550

What are the solutions to the quadratic function x^2-16=0

Mama L [17]

Answer:

x = ± 4

Step-by-step explanation:

Given

x² - 16 = 0 ( add 16 to both sides )

x² = 16 ( take the square root of both sides )

x = ± $\sqrt{16}$ = ± 4

Solutions are x = - 4 or x = 4
