X          1           2        3         4
p(x)    0.40    0.20   0.15     ?

If the items are only 4. The total of the probability must be 1 or 100%

1 - 0.40 - 0.20 - 0.15 = 0.25

The probability of 4 is 0.25.

Primitive function for:<br><br> 1. f(x)=4e2x+e−x, sådan att F(0)=2
Free_Kalibri [48]

The primitive function for f(x) = 4e^{2x} + e^{-x} is given by it's indefinite integral.

To calculate it, recall:

\frac{d}{dx}e^{ax}=ae^{ax}

\int c f(x)dx = c\int f(x)dx

Let's begin

\int 4e^{2x}+e^{-x}dx \\4\int e^{2x}dx+ \int e^{-x}dx\\4\frac{e^{2x}}{2}+\frac{e^{-x}}{-1}  + c\\

F(x) = 2e^{2x}-e^{-x} +c

To find the costant, we just need to use the fact that F(0)=2

F(0) = 2 \\4e^{0}+e^{0} + c =2\\5+c =2\\c=-3

Therefore,

\boxed{F(x) = 2e^{2x} - e^{-x} -3 }

What is the surface area of this net?
balandron [24]

Answer:

It is 27.4

Step-by-step explanation:

First you need to find the area of the three rectangle.

Area=base*high

You do 4*2 for about 3 times

Which is 8 for 4*2

Then you multiply it 3 more time and get 24.

After that you add 24+1.7+1.7 and get 27.4
