This problem involves Statistics. When you are talking about the number of deviations, you directly refer to what we called the Empirical Rule.
The empirical rule states that 95% of the values will lie within 2 standard deviations of the mean. So 100% - 95% = 5% of the parts will be rejected. So
(0.05)*(15,000) = 750
Therefore, 750 machine parts are rejected. Hope this helps! :D
1050 feet of room can be painted with 3 gallon of paint
<u>Solution:</u>
Given, 280 ft of room painted with 4/5 gallon of paint
We have to find how many feet can you paint with 3 gallon
Now, according to given information,
gallon of paint ⇒ 280 feet of room
Then, 3 gallon of paint ⇒ "n" feet of room
So by chris cross method, we get
![\begin{array}{l}{n \times \frac{4}{5}=3 \times 280} \\\\ {n=3 \times 280 \times \frac{5}{4}} \\\\ {n=3 \times 70 \times 5} \\\\ {n=210 \times 5=1050}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bl%7D%7Bn%20%5Ctimes%20%5Cfrac%7B4%7D%7B5%7D%3D3%20%5Ctimes%20280%7D%20%5C%5C%5C%5C%20%7Bn%3D3%20%5Ctimes%20280%20%5Ctimes%20%5Cfrac%7B5%7D%7B4%7D%7D%20%5C%5C%5C%5C%20%7Bn%3D3%20%5Ctimes%2070%20%5Ctimes%205%7D%20%5C%5C%5C%5C%20%7Bn%3D210%20%5Ctimes%205%3D1050%7D%5Cend%7Barray%7D)
Hence, we can paint 1050 ft of the room with 3 gallons of paint.
The arc angle is twice (i.e. two times) the angle subtended between the chord and the tangent.
Since the arc is 118 degrees, the angle subtended at the tangent point is 59 degrees.
Angle d is therefore
= 180-59 = 121 degrees. (which is not shown in the answer options)
