#18 i can't figure this out
Anon25 [30]

Answer:

∠Q = 75 °

Step-by-step explanation:

Since PR = PQ then Δ PQR is isosceles and the base angles are congruent, that is

∠R = ∠Q = 2x + 15

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180

2x + 15 + 2x + 15 + x = 180, that is

5x + 30 = 180 ( subtract 30 from both sides )

5x = 150 ( divide both sides by 5 )

x = 30

Hence

∠Q = 2x + 15 = (2 × 30) + 15 = 60 + 15 = 75°

Pentagon CRAFT has coordinates c(-2,1) r(-5,2) a(-6,7) f(-3,9) and t(-1,6) and is dilated by a scale factor of 2/3 at the origin
Vsevolod [243]

Answer:

First, we need to know the formula when a scale factor appears:

New coordinate =  (scale factor)*(old coordinate)

So using this formula we have:

1) c' = (-2,1)*2/3  

  c' = (-4/3,2/3)

2) r = (-5,2)*2/3

   r = (-10/3,4/3)

3) a = (-6,7)*2/3

   a = (-4,14/3)

4) f = (-3,9)*2/3

   f = (-2,6)

5) t = (-1,6)*2/3

   t = (-2/3,4)

What is the standard error of the proportion if 80% of the 1,200 respondents in a yes/no survey answered "no"?
saw5 [17]
Standard error for a sample proportion, p = 0.8, n = 1200

SE= \sqrt{ \frac{p(1-p)}{1200} } = \sqrt{ \frac{0.8(1-0.8)}{1200} } \approx 0.015 \times 100\%=1.15\%
