7×(15+7-4+(x+y×38))^3 when x = 4 and y = 9

7×(15+7-4+(4+9×38))^3

=> 7×(15+7-4+(4+342))^3

=> 7×(15+7-4+346)^3

=> 7×364^3

=> 7×48228544

=> 337599808

What is the third quartile of this data set 20,21,24,25,28,29,35,37,39,42,44

dezoksy [38]

Answer:

The third quartile would be 39.

Step-by-step explanation:

• Since the numbers are already in order, the next step would be to find the median:

- The median is the middle number; found by ordering all data points and picking out the one in the middle.

The median would be 29.

• The first quartile, is denoted as Q1 and is the middle number that falls between the smallest value of the data set and the median.

The first quartile would be 24.

• The third quartile, is denoted as Q3 and is the median of the upper half of the data set.

The third quartile would be 39.

PLEASE HELP L has y-intercept (0,5) and is perpendicular to the line with equation y=1/3x+1

marin [14]

Answer:

y=-3x+5

Explanation:

Given a line L such that:

• L has y-intercept (0,5); and

• L is perpendicular to the line with equation y=(1/3)x+1.

We want to find the equation of the line in the slope-intercept form.

The slope-intercept form of the equation of a straight line is given as:

$\begin{equation} y=mx+b\text{ where }\begin{cases}m={slope} \\ b={y-intercept}\end{cases} \end{equation}$

Comparing the given line with the form above:

$y=\frac{1}{3}x+1\implies Slope,m=\frac{1}{3}$

Next, we find the slope of the perpendicular line L.

• Two lines are perpendicular if the product of their slopes is -1.

Let the slope of L = m1.

Since L and y=(1/3)x+1 are perpendicular, therefore:

$\begin{gathered} m_1\times\frac{1}{3}=-1 \\ \implies Slope\text{ of line L}=-3 \end{gathered}$

The y-intercept of L is at (0,5), therefore:

$y-intercept,b=5$

Substitute the slope, m=-3, and y-intercept, b=5 into the slope-intercept form.

$\begin{gathered} y=mx+b \\ y=-3x+5 \end{gathered}$

The equation of line L is:

$y=-3x+5$
