y is
. This is because in a 30-60-90 triangle, the side facing the 30° is always half of the side facing the 90°
x is always √3 times y, so x=24. Therefore, the answer is the second answer choice.
M=(6-1)/(8-5)=5/3
y=5x/3+b, using (5,1)
1=25/3+b
b=-22/3
y=(5x-22)/3
...
m=(8-3)/(-1--4)=5/3...
y=5x/3+b, using (-1,8)
8=-5/3+b
b=29/3
y=(5x+29)/3
Since they have the same slope and difference y-intercepts they are parallel lines and will never intersect.
The mean of the given sample data is 210, and the standard deviation is 7.937.
Given size 'n' = 300
The population proportion 'p' = 0.7
Let 'x' be the random variable of the binomial distribution
a) mean of the binomial distribution = n p = 300 × 0.7
μ = 210
b) variance of the binomial distribution
⇒ n p q
⇒ 300 × 0.7 ×0.3
⇒ σ² = 63
The standard deviation of the binomial distribution:
⇒ √n p q = √63 = 7.937
Thus, the mean of the given sample data is 210, and the standard deviation is 7.937.

The question seems to be incomplete the correct question would be:
describe the sampling of p hat. Assume that the size of the population is 25000 n= 300 p=0.7 a) Determine the mean of the sampling distributionb) Dtermine the standard deviation of the sampling distribution
I believe it’s option #3. hopefully that helps :)
Answer:
<u>-289 degrees</u>
Step-by-step explanation:
You are looking for what is called <u>Coterminal Angles</u>.
To find a coterminal angle between 0 and 360 you <u>add or subtract</u> 360.
- In this case, we subtracted 360 from 71
- 71 - 360 = -289
- tan(-289) = 2.90
- If TAN 71 = 2.90 and TAN -289 = 2.90, you know -289 is your answer.
