Find the slope between these two points: (3, -10) and (-2, -30). Show all of your work. what the answer

Harlamova29_29 [7]

$\huge\text{$m=\boxed{4}$}$

Hey there! Start with the slope formula, where $(x_1,y_1)$ and $(x_2,y_2)$ are the two known points.

$\begin{aligned}m&=\dfrac{y_2-y_1}{x_2-x_1}\\&=\frac{-30-(-10)}{-2-3}\end{aligned}$

Simplify.

$\begin{array}{c|l}\textbf{Solving}&\textbf{Reason}\\\cline{1-2}\\m=\dfrac{-30+10}{-2-3}&x-(-y)=x+y\\\\m=\dfrac{-20}{-5}&\text{Addition and subtraction}\\\\m=\dfrac{20}{5}&\text{The negatives cancel out}\\\\m=\dfrac{4}{1}&\text{Divide the numerator and denominator by $5$}\\\\m=\boxed{4}&\dfrac{x}{1}=x\end{aligned}$

What is the mean absolute deviation of the following data set 3, 13, 11, 5

charle [14.2K]

Answer:

Step-by-step explanation:

Add up your data. 3+13+11+5=32
Divide the sum by the number of data you have. In your case you would divide 32/4/
This will give you 8, which is your mean. Now, subtract 8 from each value and put the difference to its absolute value.
Now, add up each of these values (5+5+3+3=16), then divide by 4. This will give you an answer of 4.

Hope this helps! Have a great day :)

A rectangular brick walkway has a length of ten feet and a width of four feet.The length and the width of the walkway will each

ankoles [38]

Answer:

$\boxed{\text{22.5 ft}^{2}}$

Step-by-step explanation:

Existing walkway

l = 10 ft

w = 4 ft

A₁ = lw = 10 ft × 4 ft = 40 ft²

New walkway

Expanding a measurement by 25 % means that you multiply it by a factor of 1.25.

New length = 10 × 1.25 = 12.5 ft

New width = 4 × 1.25 = 5 ft

A₂ = lw = 12.5 ft × 5 ft = 62.5 ft²

Increase in area

A₂ - A₁ = 62.5 – 40 = 22.5 ft²

The increase in area is $\boxed{\textbf{22.5 ft}^{2}}$
