The endpoints of PQ are P(2, 0) and Q (4, 2). Find the coordinates of midpoint PQ.
lawyer [7]

Answer:

Step-by-step explanation:

Parameterize the ellipse as (acos∙,bsin∙). Take points P:=(acosp,bsinp) and Q:=(acosq,bsinq) on the ellipse, with midpoint M:=(P+Q)/2.

If |PQ|=2k, then

a2(cosp−cosq)2+b2(sinp−sinq)2=4k2

The coordinates of M are

xy==a2(cosp+cosq)b2(sinp+sinq)

Find Mean, Median, mode and range. Round to the nearest tenth.
Zigmanuir [339]

Answer:

Mean =26.2

Median=27

Mode=32

Range=38

Step-by-step explanation:

From the stem and leaf plot, we obtain the original data as:

9,11,12,12,14,17,25,25,27,32,32,32,33,35,41,42,47

The median is middle observation of the array.

Thebefore the median is 27

The mode is the number that occurs most.

The mode is 32.

The range is the highest observation minus the least observation.

The range is 47-9=38

The mean is given by:

\bar x =  \frac{9 + 11 + 12 + 12 + 14 + 17 + 25 + 25 + 27 + 32 + 32 + 32 + 33 + 35 + 41 + 42 + 47}{17}

\bar x =  \frac{446}{17}  = 26.24

Write an equation in slope-intercept form for the line.<br><br> slope = 0, y-intercept = 3
Anit [1.1K]

Answer:  y = 0x+3 or y = 3

The slope is 0 and the y intercept is 3. So m = 0 and b = 3.

Plug those into y = mx+b to get y = 0x+3, and that simplifies to y = 3.

This graphs out a horizontal line that passes through the two points (0,3) and (1,3).
