Answer:
mZWX = 214°
Step-by-step explanation:
In a circle C, XR and WZ are two diameters.
∠ XCW = 34° and ∠ YCZ = 86°
We have to find the measure of arc ZWX
Since ∠XCW + ∠XCY + ∠YCZ = 180° [ angles on a straight line ]
34° + ∠XCY + 86° = 180°
120° + ∠XCY = 180°
∠XCY = 180 - 120 = 60°
Now arc ZWX = 360° - (∠XCY + ∠ YCZ)
= 360° - (60° + 86°)
= 360° - 146°
= 214°
Therefore answer is arc ZWX = 214°
It’s should be -10 answer
Twice. Dividing by ten will move the decimal point one place to the left. Rather than dividing by ten twice, you can divide by 100 once.
Answer: 0.03855
Step-by-step explanation:
Given :A population of skiers has a distribution of weights with mean 190 pounds and standard deviation 40 pounds.
Its maximum safe load is 10000 pounds.
Let X denotes the weight of 50 people.
As per given ,
Population mean weight of 50 people = 
Standard deviation of 50 people 
Then , the probability its maximum safe load will be exceeded =
![P(X>10000)=P(\dfrac{X-\mu}{\sigma}>\dfrac{10000-9500}{282.84})\\\\=P(z>1.7671-8)\\\\=1-P(z\leq1.7678)\ \ \ \ [\because\ P(Z>z)=P(Z\leq z)]\\\\=1-0.96145\ \ \ [\text{ By p-value of table}]\\\\=0.03855](https://tex.z-dn.net/?f=P%28X%3E10000%29%3DP%28%5Cdfrac%7BX-%5Cmu%7D%7B%5Csigma%7D%3E%5Cdfrac%7B10000-9500%7D%7B282.84%7D%29%5C%5C%5C%5C%3DP%28z%3E1.7671-8%29%5C%5C%5C%5C%3D1-P%28z%5Cleq1.7678%29%5C%20%5C%20%5C%20%5C%20%5B%5Cbecause%5C%20P%28Z%3Ez%29%3DP%28Z%5Cleq%20z%29%5D%5C%5C%5C%5C%3D1-0.96145%5C%20%5C%20%5C%20%5B%5Ctext%7B%20By%20p-value%20of%20table%7D%5D%5C%5C%5C%5C%3D0.03855)
Thus , the probability its maximum safe load will be exceeded = 0.03855
20L = 20,000mL. 20,000 / (22+3) people = 800mL/person
