shusha [124]

Answer:

47.

Step-by-step explanation:

1) the rule:

$f_{avr}=\frac{1}{b-a} \int\limits^b_a {f(x)} \, dx ,$

where a;b are 0 and 12, f(x)=x²-1.

2) according to the rule above:

$f_{avr}=\frac{1}{12-0} \int\limits^{12}_0 {(x^2-1)} \, dx=\frac{1}{12}(\frac{x^3}{3}-x)|^{12}_0=48-1=47.$

Of the 48 oranges in a carton 1/3 of them were rotten Ben and David took the remaining good oranges it's been took eat my orange

Burka [1]

Answer:

David took 16 oranges.

Step-by-step explanation:

We are given the following in the question:

Total number of oranges = 48

Oranges rotten =

$\dfrac{1}{3}$

Number of oranges rotten =

$\dfrac{1}{3}\times 48\\\\=16$

There were 16 rotten oranges.

Number of good oranges left =

$= 48-16\\=32$

These are equally divided among Ben and David.

Number of oranges each Ben and David get =

$\dfrac{32}{2} = 16$

Thus, David took 16 oranges.
