Use the Law of Sines (sina/A=sinb/B=sinc/C for any triangle)

YZ/sin30=50/sin90

YZ=50sin30 (sin90=1 :P)

YZ=25m

Use the 30,60,90° triangle ratios 1, √3, 2

YZ/1=50/2

YZ=25m

Using the Pythagorean Theorem....

(2*25)^2=YZ^2+(√3*YZ)^2

2500=YZ^2+3YZ^2

2500=4YZ^2

625=YZ^2

25m=YZ

Answer:

The mean of the sampling distribution of sample proportions will be 0.2

Step-by-step explanation:

Central Limit Theorem for Proportions:

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean $\mu = p$ and standard deviation $s = \sqrt{\frac{p(1-p)}{n}}$

20% of American adults ages 25 and older had never been married.

This means that $p = 0.2$

So the mean of the sampling distribution of sample proportions will be 0.2

Z +6 divided by 1/3 = 4

Allushta [10]

Hey there!!

z + 6 / 1/3 = 4

z + 6 = 4 × 1/3

z + 6 = 4/3

z = 4/3 - 6

z = 4 - 18 / 3

z = -14/3

Hope it helps!
