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

×WILL MARK AS BRAINLIEST×<br>Solve the equation for b, d and x

Lera25 [3.4K]

Solve for d:
(3 (a + x))/b = 2 d - 3 c
(3 (a + x))/b = 2 d - 3 c is equivalent to 2 d - 3 c = (3 (a + x))/b:
2 d - 3 c = (3 (a + x))/b
Add 3 c to both sides:
2 d = 3 c + (3 (a + x))/b
Divide both sides by 2:
Answer: d = (3 c)/2 + (3 (a + x))/(2 b)

-----------------------------

Solve for x:
(3 (a + x))/b = 2 d - 3 c
Multiply both sides by b/3:
a + x = (2 b d)/3 - b c
Subtract a from both sides:
Answer: x = (2 b d)/3 + (-a - b c)

____________________________

Solve for b:
(3 (a + x))/b = 2 d - 3 c
Take the reciprocal of both sides:
b/(3 (a + x)) = 1/(2 d - 3 c)
Multiply both sides by 3 (a + x):
Answer: b = (3 (a + x))/(2 d - 3 c)
