Let be the density function for the shelf life of a brand of banana which lasts up to weeks. Time, , is measured in weeks and .

Maurinko [17]

The question is incomplete. The complete question is :

Let $p(t) = -0.0375t^2 + 0.225t$ be the density function for the shelf life of a brand of banana which lasts up to 4 weeks. Time, t, is measured in weeks and $0 \leq t \leq 4$ . Incorrect answer icon Your answer is incorrect. Find the mean shelf life of a banana using . Round your answer to one decimal place.

Answer:

2.4

Step-by-step explanation:

Given :

$p(t) = -0.0375t^2 + 0.225t$

Mean :

$=\int_0^4 tp (t) \ dt$

$=\int_0^4 t (0.0375 t^2 + 0.225t) \ dt$

$=-0.0375 \int_0^4 t^3 \ dt + 0.225 \int_0^4 t^2 \ dt$

$=-0.0375 \left[ \frac{t^4}{4} \right]^4_0 + 0.225 \left[ \frac{t^3}{3} \right]^4_0$

$=-0.0375 (64) + 0.225 \left( \frac{64}{3} \right)$

$=-2.5 + 4.8$

= 2.4

Therefore, the mean is 2.4

Weekly demand for a particular item averages 30 units, with a standard deviation of 4. This item is managed with a fixed-order-i

bezimeni [28]

Answer: 93 units should be ordered.

Step-by-step explanation:

Since we have given that

Standard deviation = 4

Average = 30 units

Number of weeks in order interval = 3

Desired service level = 97.5%

Number of units on hand = n = 43

So, the expected value would be

$E[x]=30\times (3+1)+1.96\times 4\sqrt{3+1}-43\\\\E[x]=30\times 4+1.96\times 4\times 2-43\\\\E[x]=120+15.68-43\\\\E[x]=92.68\approx 93$

Hence, 93 units should be ordered.
