Step-by-step explanation:

To find the mean, add up all the numbers

15+15+25+29 =84

Divide by the number of numbers

84/4 = 21

Find the equation of the line that
Aleonysh [2.5K]

Answer:

y = 3x/2-14

Step-by-step explanation:

We are given that the line is perpendicular to y = -2/3 and contains (4,-8).

<u>P</u><u>e</u><u>r</u><u>p</u><u>e</u><u>n</u><u>d</u><u>i</u><u>c</u><u>u</u><u>l</u><u>a</u><u>r</u><u> </u><u>D</u><u>e</u><u>f</u><u>.</u>

\displaystyle \large{m_1m_2 =  - 1}

Both slopes multiply each others equal to -1.

Finding another slope that is perpendicular to -2/3, substitite m1 = -2/3 in.

\displaystyle \large{ -  \frac{2}{3} m_2 =  - 1}

Multiply both sides by 3.

\displaystyle \large{ -  \frac{2}{3} m_2( 3) =  - 1(3)} \\  \displaystyle \large{ -  2 m_2=  - 3} \\  \displaystyle \large{  m_2=  \frac{3}{2} }

Therefore, another slope that is perpendicular to -2/3 is 3/2.

Then rewrite in slope-intercept form.

<u>S</u><u>l</u><u>o</u><u>p</u><u>e</u><u>-</u><u>I</u><u>n</u><u>t</u><u>e</u><u>r</u><u>c</u><u>e</u><u>p</u><u>t</u>

\displaystyle \large{y  = mx + b}

where m = slope and b = y-intercept; substitute m = 3/2 in.

\displaystyle \large{y  =  \frac{3}{2} x + b}

Since the line contains (4,-8), substitute x = 4 and y = -8 in and solve for b.

\displaystyle \large{ - 8 =  \frac{3}{2} (4) + b} \\  \displaystyle \large{ - 8 =  3(2)+ b} \\  \displaystyle \large{ - 8 =  6 +  b} \\  \displaystyle \large{ - 8 - 6 =  b} \\  \displaystyle \large{ - 14 =  b}

Therefore, b is -14; rewrite again in slope-intercept form.

Thus:-

\displaystyle \large{y  =  \frac{3}{2} x + b} \\  \displaystyle \large{y  =  \frac{3}{2} x  - 14}

What is a rate and a unit rate examples
mojhsa [17]

Answer:Rates. ... When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
