1) "a" and 60° are vertical angles, hence equal. a = 60°

2) "b" is the supplement to 60°, so is 180° - 60° = 120°. b = 120°

3) "d" is the supplement to 65°, so is 180° - 65° = 115°. d = 115°

4) "e" and 65° are vertical angles, hence equal. e = 65°

5) "g" is the supplement to 55°, so is 180° - 55° = 125°. g = 125°

6) "h" and 55° are vertical angles, hence equal. h = 55°

Find the distance between the two points. (round to the nearest hundredths)
4vir4ik [10]

Answer:

d = 5.10

Step-by-step explanation:

The distance between two points is given by

d = sqrt( ( y2-y1)^2 + ( x2-x1)^2 )  where ( x1,y1) and ( x2,y2) are the two points

d = sqrt( ( 5-6)^2 + (8-3)^2 )  

d = sqrt( ( -1)^2 + (5)^2 )  

d = sqrt(  1+25)

d = sqrt(26)

d = 5.099019514

Rounding to the nearest hundredth

d = 5.10

A simple random sample from a population with a normal distribution of 102 body temperatures has x overbarequals98.40degrees Upp
Oliga [24]

Answer:

It is 80% statistically safe to conclude that the population standard deviation is less than 1.8°F

Step-by-step explanation:

The given information are;

The sample size, n = 102

The sample mean = 98.4°F

The sample standard deviation = 0.66°F

\sqrt{\dfrac{\left (n-1  \right )s^{2}}{\chi _{\alpha /2}^{}}}< \sigma < \sqrt{\dfrac{\left (n-1  \right )s^{2}}{\chi _{1-\alpha /2}^{}}}

α = 0.2, ∴ α/2 = 0.1

\chi _{1-\alpha /2} = \chi _{0.9, 101} = 83.267

\chi _{\alpha /2} = \chi _{0.1, 101} = 119.589,

Which gives;

\sqrt{\dfrac{\left (102-1  \right )0.66^{2}}{119.589}^{}}}< \sigma < \sqrt{\dfrac{\left (102-1  \right )0.66^{2}}{83.267}^{}}}

0.607 < σ <0.727

Therefore, it is 80% statistically safe to conclude that the population standard deviation is less than 1.8°F.
