Answer:
Step-by-step explanation:
I think across from each other is more direct. You could say two angles that are on opposite ends of a diagonal. That is probably clearest of all, now that I think of it.
Answer: 0.0142
Step-by-step explanation:
Given : The mean height of women in a country (ages 20 - 29) is 64.2 inches.
i.e. 
Also, 
Sample size : n= 50
Let x denotes the height of women.
Then, the probability that the mean height for the sample is greater than 65 inches :-
![P(x>65)=1-P(x\leq 65)\\\\=1-P(\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}\leq\dfrac{65-64.2}{\dfrac{2.58}{\sqrt{50}}})\\\\=1-P(z\leq2.193)\ \ [\because z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}]\\\\=1-0.9858463\ \ [\text{By using z-value table or calculator}]\\\\=0.0141537\approx0.0142](https://tex.z-dn.net/?f=P%28x%3E65%29%3D1-P%28x%5Cleq%2065%29%5C%5C%5C%5C%3D1-P%28%5Cdfrac%7Bx-%5Cmu%7D%7B%5Cdfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%7D%5Cleq%5Cdfrac%7B65-64.2%7D%7B%5Cdfrac%7B2.58%7D%7B%5Csqrt%7B50%7D%7D%7D%29%5C%5C%5C%5C%3D1-P%28z%5Cleq2.193%29%5C%20%5C%20%5B%5Cbecause%20z%3D%5Cdfrac%7Bx-%5Cmu%7D%7B%5Cdfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%7D%5D%5C%5C%5C%5C%3D1-0.9858463%5C%20%5C%20%5B%5Ctext%7BBy%20using%20z-value%20table%20or%20calculator%7D%5D%5C%5C%5C%5C%3D0.0141537%5Capprox0.0142)
Hence, the the probability that the mean height for the sample is greater than 65 inches = 0.0142
Answer:
v = 6
Step-by-step explanation:
<u>Given</u>
3(3v-5) = 39
So,
3v - 5 = 39 / 3
=> 3v - 5 = 13
=> 3v = 13 + 5
=> 3v = 18
=> v = 18 / 3
=> v = 6

Answer:
PQR is an equilateral triangle because its sides are equal. ... Since radius of the incircle is equal to the side length of the hexagon, all sides of the triangle are equal, thus, creating an equilateral triangle. I hope this helped.
