Answer:
c
Step-by-step explanation:
the equation would be C because
A would end up with a negative amount
B is more than she originally has to paint and
D has the wrong coefficient for <em> t</em>.
Answer:
a
![P( X > 46) = 0.7 \ minute](https://tex.z-dn.net/?f=P%28%20X%20%3E%20%2046%29%20%20%3D%200.7%20%5C%20%20minute)
b
![\mu = 42 \ minute](https://tex.z-dn.net/?f=%5Cmu%20%20%3D%2042%20%5C%20minute)
Step-by-step explanation:
From the question we are told that
The procedure for performing a certain task is uniformly distributed on the interval from( a = 32 )minutes to (b= 52) minutes
Generally the cumulative distribution function for continuous uniform distribution is
Generally the probability that it takes more than 46 minutes to learn the procedure is mathematically represented as
![P( X > 46) = F(46) = \frac{46 - 32}{52-32}](https://tex.z-dn.net/?f=P%28%20X%20%3E%20%2046%29%20%20%3D%20F%2846%29%20%3D%20%5Cfrac%7B46%20-%2032%7D%7B52-32%7D)
=> ![P( X > 46) = 0.7 \ minute](https://tex.z-dn.net/?f=P%28%20X%20%3E%20%2046%29%20%20%3D%200.7%20%5C%20%20minute)
Generally the average time required to learn the procedure is mathematically represented as
![\mu = \frac{a + b}{2}](https://tex.z-dn.net/?f=%5Cmu%20%3D%20%20%5Cfrac%7Ba%20%2B%20b%7D%7B2%7D)
=> ![\mu = \frac{32 + 52}{2}](https://tex.z-dn.net/?f=%5Cmu%20%20%3D%20%20%5Cfrac%7B32%20%2B%2052%7D%7B2%7D)
=> ![\mu = 42 \ minute](https://tex.z-dn.net/?f=%5Cmu%20%20%3D%2042%20%5C%20minute)
