Determining the proper option, acquiring evidence, and exploring various options are all steps in the decision-making process.

Jorge wants to find the most popular way for teens to volunteer in the community. He cannot decide between two methods.

Option 1: He will ask every fifth person on each English class roster. This is a biased one because the best one can be skipped.

Option 2: He will attend a walkathon to ask teen participants about the ways they volunteer. Because all the volunteers participated that can be observed.

Answer:

The given expression is irrational because one factor is irrational

Step-by-step explanation:

Given the expression

[tex](\sqrt{576})(\sqrt{684})[/tex]

we have to find that the product is rational or irrational.

[tex]\sqrt{576}=\sqrt{26\times 26}=26[/tex]

[tex]\sqrt{684}=\sqrt{2 \times 2 \times 3 \times 3 \times 19}=2\times 3\sqrt{19}=6\sqrt{19}[/tex]

[tex]\text{The square root of 19 is irrational }[/tex]

[tex]\text{The square root of 684 is irrational }[/tex]

Hence, the first factor of the expression is rational and the second factor is irrational therefore the product is irrational.

Answer:

A. Solve w+2 = 7w-16 to find the value of w.

Step-by-step explanation:

Here p represents the age of Peter and w represents the age of Winnie,

Given,

Peter is 2 years older than Winnie.

⇒ p = w + 2 -----(1)

Also, Peter's age is 16 years less than seven times Winnie's age.

⇒ p = 7w - 16 -----(2),

By equating right sides of equation (1) and (2),

We get,

w + 2 = 7w - 16,

Since, this equation is only in the variable w,

Thus, we can find the value of w with help of the above equation,

After putting this value in either of equation (1) or (2),

We can find the value of p.

Hence, option A is correct.

Note : From equation (1) and (2),

w = p - 2 and [tex]w=\frac{p+16}{7}[/tex]

[tex]\implies p-2=\frac{p+16}{7}[/tex]

⇒ Option B is incorrect.

Now, let x represents w and y represents p in the graph,

Then, the solution will be the intersection point of lines y=x+2 and y=7x-16,

Which is shown below,

⇒ Options C and D are incorrect.

Step-by-step explanation:

Answer:

  √2

Step-by-step explanation:

You want the distance between the lines y = -x +2 and y = -x +4.

The distance from point (x, y) to line ax +by +c = 0 is given by the formula ...

  [tex]d=\dfrac{|ax+by+c|}{\sqrt{a^2+b^2}}[/tex]

Rewriting the equation of the second line to general form, we have ...

  y = -x +4

  x +y -4 = 0 . . . . . . . a=1, b=1, c=-4

The equation of the first line is written in slope intercept form, so we can identify the y-intercept as (0, 2). Using this point in the formula for the distance to the second line, we have ...

  [tex]d=\dfrac{|1(0)+1(2)-4|}{\sqrt{1^2+1^2}}=\dfrac{|-2|}{\sqrt{2}}=\sqrt{2}[/tex]

The distance between the lines is √2 units.

Additional comment

As you can see from the graph, the distance between the lines is the length of the diagonal of a unit square, √2.

Answer:

The scale factor is equal to [tex]\frac{1}{2}[/tex] or [tex]0.5[/tex]

Step-by-step explanation:  

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z-----> the scale factor

[tex]z^{3}=\frac{45}{360}= \frac{1}{8}\\ \\z=\sqrt[3]{\frac{1}{8}}\\ \\z=\frac{1}{2}[/tex]

The solution for (w) is  W= 4k-2b / -5, corresponding to option A.

To solve the equation [tex]\(k = \frac{2b - 5w}{3k}\)[/tex] for (w), we follow these steps:

1. Isolate the term containing (w):

  Multiply both sides of the equation by (3k) to eliminate the denominator:

[tex]\[3k^2 = 2b - 5w\][/tex]

2. Isolate (w):

  Subtract \(2b\) from both sides of the equation:

[tex]\[3k^2 - 2b = -5w\][/tex]

3. Divide both sides by (-5):

  Divide both sides of the equation by (-5) to isolate (w):

[tex]\[w = \frac{3k^2 - 2b}{-5}\][/tex]

Now, let's summarize the answer:

The solution for (w) is given by option:

[tex]\[\boxed{\text{(A) } w = \frac{4k - 2b}{-5}}\][/tex]

Final answer:

To find the slope-intercept form of a line with a given slope of -5/2 that passes through the point (8, -1), we use the point-slope form and then rearrange to get the final equation: y = (-5/2)x + 19.

Explanation:

To write the equation of a line in slope-intercept form (which is y = mx + b), we need to know the slope (m) of the line and the y-intercept (b). In this case, we are given the slope of the line as -5/2 and a point through which the line passes, which is (8, -1). Using the point-slope form, which is y - y1 = m(x - x1) where (x1, y1) is the given point and m is the slope, we can substitute the given slope and the coordinates of the given point to derive the slope-intercept form.

The equation starts with y - (-1) = (-5/2)(x - 8). Simplifying the equation, we get:

y + 1 = (-5/2)x + (5/2)*8

y = (-5/2)x + 20 - 1

y = (-5/2)x + 19

So, the equation of the line in slope-intercept form is y = (-5/2)x + 19.

To write an equation in slope-intercept form, substitute the given values of the slope and a point on the line into the equation. The equation of the line passing through the point (8, -1) with a slope of -5/2 is y = -5/2x + 19.

To write an equation in slope-intercept form, we need to use the given slope and the coordinates of the point through which the line passes. The slope-intercept form is y = mx + b, where m represents the slope and b represents the y-intercept. We're given that the slope of the line is -5/2, so we can substitute this value for m. We're also given that the line passes through the point (8, -1), so we can substitute these coordinates to find the value of b.

Using the point-slope form of a line, we have y - y1 = m(x - x1). Substituting the given values, we get y - (-1) = -5/2(x - 8). Simplifying, we have y + 1 = -5/2x + 20. Moving the 1 to the other side, we have y = -5/2x + 19. This is the equation of the line in slope-intercept form.

Hope it will find you well.

we are given

radius=r=12m

height=h=9m

now, we can use formula of volume of cylinder

[tex] V=\pi r^2 h [/tex]

now, we can plug values

and we get

[tex] V=\pi (12)^2 *9 [/tex]

we get

[tex] V=1296 \pi m^3 [/tex]

so, the exact volume of the cylinder is [tex] 1296 \pi m^3 [/tex]..........Answer

Answer:

(D)

Step-by-step explanation:

It is given that a cylinder has a radius of 12 m and a height of 9 m.  Then,

Volume of the cylinder is given as:

[tex]V={\pi}r^{2}h[/tex]

⇒[tex]V={\pi}(12)^2(9)[/tex]

⇒[tex]V={\pi}(144)(9)[/tex]

⇒[tex]V=1296{\pi}m^3[/tex]

Therefore, the volume of the cylinder is [tex]1296{\pi}m^3[/tex].

Thus, Option D is correct.
