Answer:

$if \ given \ 2 \ points\ are\ (x_1, y_1) \ and\ (x_2, y_2) \\ then \ slope \ is \ given \ as \ \\m = \frac{(y_2 -y_1)}{x_2 -x_1} \\$

Step-by-step explanation:

I think now you can figure it out. let me know if needed more clarification. It will help you to get started

Answer:

slope = - $\frac{8}{11}$

Step-by-step explanation:

To calculate the slope m use the slope formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (20, 8) and (x₂, y₂ ) = (9, 16)

m = $\frac{16-8}{9-20}$ = $\frac{8}{-11}$ = - $\frac{8}{11}$

A cylinder container 18 inches tall and a diameter of 12 inches is completely filled with vanilla, chocolate, and strawberry ice

Jet001 [13]

If the diameter of the cylinder is 12 inches, then the radius is half that, or 6.

now, the flavors are on a ratio of 3:2:1, that simply means, we can just get the volume of the cylinder in total, and divide it by (3+2+1), and the vanilla flavor gets 3 of that quotient.

$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h~~
\begin{cases}
r=radius\\
h=height\\
-----\\
h=18\\
r=6
\end{cases}\implies V=\pi (6^2)(18)\implies V=648\pi$

$\bf \stackrel{vanilla}{3}~~:~~\stackrel{chocolate}{2}~~:~~\stackrel{strawberry}{1}
\\\\\\
\stackrel{vanilla}{3\cdot \frac{648\pi }{3+2+1}}~~:~~\stackrel{chocolate}{2\cdot \frac{648\pi }{3+2+1}}~~:~~\stackrel{strawberry}{1\cdot \frac{648\pi }{3+2+1}}
\\\\\\
\stackrel{vanilla}{324\pi }~~:~~\stackrel{chocolate}{216\pi }~~:~~\stackrel{strawberry}{108\pi }$

Answer:

6 meters

Step-by-step explanation:

Every 7 floors, it goes up by 22.4 meter intervals.

Let's count down,

the 7th floor would be 50.8 - 22.4, which is 28.4.

the 0th floor would be 28.4 - 22.4, which is 6.

For a repeated-measures study comparing two treatments with 12 scores in each treatment, what is the df value for the t statisti

marishachu [46]

The degree of freedom for t statistic is 11.

According to the given question.

For a repeated-measure study, comparing two treatments with 12 scores in each treatment .

So, we can say that sample size, n = 12.

We know that, when you have a sample and estimate the mean, we have

n – 1 degrees of freedom, where n is the sample size.

Therefore,

The degree of freedom for the given sample test will be

d.f = n -1

⇒ d.f = 12 - 1

⇒ d.f = 11

Hence, the degree of freedom for t statistic is 11.

Answer:

d) $(9*3/4)+y$

Step-by-step explanation:

b) $9+y*(3/4)$

This expression is not equivalent, as the original expression, $y+9*\frac{3}{4}$ , has 9 multiplied to $\frac{3}{4}$ instead of y. You can interchange values like this when it comes to addition, but not multiplication.

c) $(y+9)(3/4)$

This expression is also not equivalent. After opening up the parentheses, it would again result in y being multiplied to $\frac{3}{4}$ .

$(y+9)(3/4)\\= y(3/4)+9(3/4)$

d) $(9*3/4)+y$

This expression is equivalent, as 9 and $\frac{3}{4}$ are still being multiplied together and y is added to the product. We can actually rearrange this to look like the original expression:

$(9*3/4)+y\\=y+(9*3/4)\\=y+(9*\frac{3}{4} )\\=y+9*\frac{3}{4}$

I hope this helps!
