What value of x makes the equation true?<br> -1=1 – 4(-5+4x) – 4x

cluponka [151]

Answer:

x = 11/10

Step-by-step explanation:

we have from statement:

-1=1 - 4(-5+4x) – 4x

we apply distributive property:

-1 = 1 -4*(-5) -4*(4x) -4x

so we have:

-1= 1+20 -16x -4x

-1 = 21 -20x

-22=-20x

so we have:

x=22/20

x=11/10

we can substitute the x value found:

-1 = 1 - 4(-5+4*(11/10)) – 4*(11/10)

-1 = 1+20 -17.6 -4.4

-1 =21 -22

so we have:

-1 = -1

A stick is broken at a point, chosen at random, along its length. Find the probability that the ratio, R, of the length of the s

Oksanka [162]

Solution :

Let the distance of the stick from one break be X

And let us assume that $X \leq l/2$ .

Here, l = length of stick

Therefore, $$P(X$

We know that, $R=\frac{X}{l-X}$ , so by definition we get

$X =\frac{lR}{1+R}$

The cumulative distribution function for R is

$$P(R$

When it starts at zero, then r =0. It ends at one when the r has a maximum

value of one.

The probability density function is given by

$\frac{d}{dr}(\frac{2r}{1+r})= \frac{2}{(r+1)^2}$

Now integrating, we find E(R) and $E(R)^2$ gives :

$E(R) =\int\limits^1_0 \frac{2r}{(1+r)^2} \, dr = 2 \ln 2-1$

$E(R)^2= 3 - 4\ln 2$

Therefore, Var(R)= $2-4(\ln \ 2)^2$

The International Business Club starts the school year with $250.50 in their account. They spend $35 each month on activities. T

valina [46]

For The International Business Club: y = 250.50 - 35m,
For The Future Agricultural Leaders Club: y = 300 - 45.25m.

So the answer is 250.5 - 35m = 300 - 45.25m
