<h3>Answer:   0.8790072 approximately</h3>

Round this however your teacher instructs.

=================================================

Work Shown:

mu = 830 = mean

sigma = 96.7 = standard deviation

x = 915 = given raw score we want to convert

z = (x - mu)/sigma

z = (915 - 830)/(96.7)

z = (85)/(96.7)

z = 0.8790072 approximately

First find slope
(2-4)/(3+1) = -2/4 = -1/2
Use point (3,2)
y-y1 = m(x-x1)
Plug everything in
y-2 = -1/2(x-3)

Solution: A

Please help me with this question (bottom question)
Sliva [168]
This is another one for the "impossible geometry question" file.

Answering the last question first, the sum of exterior angles of any convex polygon is 360°.

This fact tells us that the sum of interior angles is 10*180° - 360° = 1440°. Without additional information, we do not know the measure of each interior or exterior angle.


If we assume all angles are equal, then
  Each interior = 1440°/10 = 144°
  Each exterior = 180° -144° = 36°

What are the coordinates of R' for the dilation D(0.5. p)(PQRS)?
11111nata11111 [884]

Answer:

R' = (-1,-0.5)

Step-by-step explanation:

See attachment for complete question.

From the attachment:

P = (-3,-3)

R = (1,2)

Dilation:

D_{(0.5,P)}

Required

Determine R'

First, subtract the coordinates of P from R. This means that R is measured from P.

R = (1-(-3),2-(-3))

R = (1+3,2+3)

R = (4,5)

Next, apply dilation factor 0.5

R' = R * 0.5

R' = (4,5) * 0.5

R' = (4* 0.5,5* 0.5)

R' = (2,2.5)

Lastly, measure R' from the origin by adding the coordinates of P to R'

R' = (2+(-3),2.5+(-3))

R' = (2-3,2.5-3)

R' = (-1,-0.5)
