i need the equation from the first question
Answer:
(c)
(b) The probability that time taken by Ayesha to prepare breakfast exceeds 33 minutes is 0.20.
(c) The probability that cooking or preparation time is within 2 mins of the mean time is 0.40.
Step-by-step explanation:
The random variable <em>X</em> follows a Uniform (25, 35).
(a)
The probability density function of an Uniform distribution is:
Then the probability density function of the random variable <em>X</em> is:
(b)
Compute the value of P (X > 33) as follows:
Thus, the probability that time taken by Ayesha to prepare breakfast exceeds 33 minutes is 0.20.
(c)
Compute the mean of <em>X</em> as follows:
Compute the probability that cooking or preparation time is within 2 mins of the mean time as follows:
Thus, the probability that cooking or preparation time is within 2 mins of the mean time is 0.40.
You must find the unit cost in dollars per gallon for each purchase by dividing the cost by the number of gallons.
Graven: $55.20 for 15 gallons
$55.20/(15 gal) = $3.68/gal
Project: $72.80 for 20 gallons
$72.80/(20 gal) = $3.64/gal
Answer: Project paid less per gallon.
