Answer: 17.9 km/h
Step-by-step explanation:
Convert 33 minutes and 50 seconds to Hours:
= 33 ⁵⁰/₆₀ minutes
= 33.83 minutes
In hours that would be:
= 33.83 / 60
= 0.56 hours
10,000 meters in kilometers is:
= 10,000 / 1,000
= 10 kilometers
Speed = 10 / 0.56
= 17.9 km/h

Answer: 0.1835
Step-by-step explanation:
Let x be a random variable that represents the width of the tires .
As per given , we have
![\mu=23\ mm](https://tex.z-dn.net/?f=%5Cmu%3D23%5C%20mm)
![\sigma=0.15\ mm](https://tex.z-dn.net/?f=%5Csigma%3D0.15%5C%20mm)
The company has a lower specification limit of 22.8 mm and an upper specification limit of 23.2 mm.
∵ ![z=\dfrac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
Then for x=22.8,
For x=23.2,
The probability that a tire will either be too wide or too narrow :-
![P(x23.2)\\\\=P(z1.33)\\\\=(1-P(z\leq1.33)+(1-P(z](https://tex.z-dn.net/?f=P%28x%3C22.8%29%2BP%28x%3E23.2%29%5C%5C%5C%5C%3DP%28z%3C-1.33%29%2BP%28z%3E1.33%29%5C%5C%5C%5C%3D%281-P%28z%5Cleq1.33%29%2B%281-P%28z%3C1.33%29%29%20%5C%20%5B%5Cbecause%20P%28Z%3C-z%29%3D1-P%28z%3Cz%29%20%5C%20%2C%5C%20P%28Z%3Ez%29%3D1-P%28Z%3Cz%29%5D%5C%5C%5C%5C%3D2-2%28P%28z%3C1.33%29%29%5C%20%5C%20%5B%5Cbecause%20P%28Z%5Cleq%20z%29%3DP%28Z%3Cz%29%5D%5C%5C%5C%5C%3D2-2%280.9082408%29%5C%20%5C%20%5Ctext%7B%5BUsing%20z-value%20table%5D%7D%5C%5C%5C%5C%3D0.1835184%5Capprox0.1835)
Hence, the probability that a tire will either be too wide or too narrow= 0.1835
