Answer:

strong negative linear correlation
-0.986

Step-by-step explanation:

You need to notice that when altitude goes up, temperature goes down. That means the correlation is negative.

The table shows the temperature decrease to be monotonic (nowhere does it go up when altitude increases), so the correlation is strong.

The strong negative correlation number available to you is -0.986.

___

If you want confirmation, you can put the numbers into your favorite graphing calculator and tell it to compute the correlation for you.

Line w and line v are perpendicular to each other. Line w passes through the points ( -4,8 ) and ( 12,-2 ). What is the slope of

erik [133]

The slope of line "v" is $\frac{8}{5}$

<h3>Solution:</h3>

Given that Line w and line v are perpendicular to each other

Also given that line w passes through the points ( -4, 8 ) and ( 12, -2 )

To find: slope of line v

Since line w and line v are perpendicular to each other, product of slopes of line w and line v are equal to -1

$\text {slope of line } w \times \text { slope of line } v=-1$ ---- eqn 1

Let us first find slope of line w

The slope "m" of a line is given as:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$\text {Here } x_{1}=-4 \text { and } x_{2}=12 \text { and } y_{1}=8 \text { and } y_{2}=-2$

$m=\frac{-2-8}{12-(-4)}=\frac{-10}{16}=\frac{-5}{8}$

Thus the slope of line "w" is $\frac{-5}{8}$

Substituting the slope of w in eqn 1 we get,

$\begin{array}{l}{\frac{-5}{8} \times \text { slope of line } v=-1} \\\\ {\text { slope of line } v=\frac{8}{-5} \times-1=\frac{8}{5}}\end{array}$

Thus the slope of line "v" is $\frac{8}{5}$

Find the volume of a prism with a length of 4.5 inches, width of 5 inches, and a height that is one third of the length.

evablogger [386]

Answer:

33.75

Step-by-step explanation:

Formula: Width · Height · Length

Substitute with known values: 5 · height · 4.5

Find Length: Since the height is one third of the length, we need to divide the length by three → 4.5 ÷ 3 = 1.5

Know we know that the height is 1.5.

Substitute Known Height: 5 · 1.5 · 4.5

Simplify: 5 · 1.5 · 4.5 = 33.75

Erwin earns $ 2 , 100 per month. Her deductions amount to 26 % of her paycheck. How much does Erwin take home each month?

Sergeu [11.5K]

Answer:

Credit ⇒ 45

Debit ⇒ $30

Step-by-step explanation:

Credit = $45

Debit = $30

When an account balance increases it means that it has been credited and when it decreases, it has been debited.

The beginning balance here is $0 and the closing balance is $15.

There were 2 transactions, one credit and one debit.

For the closing balance to be $15, the Credit amount must have been $15 more than the Debit amount.
