<span>The "range" of a list a numbers is just the difference between the largest and smallest values.
Example: 3, 3, 5, 6, 7, 10
The range would be 10-3=7</span>

4. Given directed line segment CD, if point E divides CD three-fourths of the way from C to D, find the coordinates of E, then p

cricket20 [7]

Answer:

Point E is given by $\left ( \frac{3mx_1+4x_0}{7},\frac{3y_1+4y_0}{7} \right )$

Step-by-step explanation:

Let points C and D be $(x_0,y_0),\,(x_1,y_1)$ and let point E divides it in ratio $m:n$ .

Then coordinates of point E are given by $\left ( \frac{mx_1+nx_0}{m+n},\frac{my_1+ny_0}{m+n} \right )$

Put $m:n=3:4$

Point E is given by $\left ( \frac{3mx_1+4x_0}{3+4},\frac{3y_1+4y_0}{3+4} \right )=\left ( \frac{3mx_1+4x_0}{7},\frac{3y_1+4y_0}{7} \right )$

Now plot point E.

In testing a certain kind of missile, target accuracy is measured by the average distance X at which the missile explodes. The d

3241004551 [841]

Answer:

The answer is c) 761.0

Step-by-step explanation:

Mathematical hope (also known as hope, expected value, population means or simply means) expresses the average value of a random phenomenon and is denoted as E (x). Hope is the sum of the product of the probability of each event by the value of that event. It is then defined as shown in the image, Where x is the value of the event, P the probability of its occurrence, "i" the period in which said event occurs and N the total number of periods or observations.

The variance of a random variable provides an idea of the dispersion of the random variable with respect to its hope. It is then defined as shown in the image.

Then you first calculate E [x] and E [ $x^{2}$ ], and then be able to calculate the variance.

$E[x]=0*\frac{1}{40} +10*\frac{1}{20} +50*\frac{1}{10} +100*\frac{33}{40}$

$E[x]=0+\frac{1}{2} +5+\frac{165}{2}$

E[X]=88

So <em>E[X]²=88²=7744</em>

On the other hand

$E[x^{2} ]=0^{2} *\frac{1}{40} +10^{2} *\frac{1}{20} +50^{2} *\frac{1}{10} +100^{2} *\frac{33}{40}$

E[x²]=0+5+250+8250

Then the variance will be:

Var[x]=8505-7744

Given x = 2^p and y = 2^q, express in terms of x and/or y

vampirchik [111]

Answer:

<h2>|||)</h2><h2>2^ (p + q) = 2^p • 2^q because you'd add the exponents, so xy</h2><h2>2^ 2q = 2^(q + q) = 2^q • 2^q as above, so y^2</h2><h2>2^ (p-1) = 2^p / 2^1 because you subtract exponents when dividing, so x/2</h2>

<h2>If xy = 32 then x = 32/y</h2><h2>so 2xy^2 would = 2(32/y)•y^2 = 64y = 32 so y = 1/2</h2><h2>making x = 64 since xy = 32</h2>
