Write a number in each blank to complete each equation so that it has the requested number of solutions. a. Equation with no sol

Setler79 [48]

Answer:

The answer is 8 $x$ - 3 $x$ + 2 - $x$ = 4  $x$ + 2  .

Step-by-step explanation:

Given:

8x - 3x + 2 -x = __ x + __

Now, to write a number in each blank to complete each equation so that it has the requested number of solutions.

So, to solve the equation:

$8x-3x+2-x$

So, we add the variables:

$5x+2-x$

And, then subtract it:

$4x-2.$

Thus, it remains:

$4x-2$ .

So the complete equation is:

8 $x$ - 3 $x$ + 2 - $x$ = 4 $x$ + 2

Therefore, the answer is 8 $x$ - 3 $x$ + 2 - $x$ = 4  $x$ + 2  .

You’ve observed the following returns on Crash-n-Burn Computer’s stock over the past five years: 14 percent, –9 percent, 16 perc

MatroZZZ [7]

Answer:

a. 9%

b. 0.01445

c. 12.02%

Step-by-step explanation:

n = 5 years

Return rates = 14%, –9%, 16%, 21%, and 3%

a. Arithmetic average return

$A= \frac{14-9+16+21+3}{5} \\A=9.00$

b. Historical variance (to 5 decimal places)

$V= \frac{\sum (X_i-A)^2}{n-1} \\V= \frac{(0.14-0.09)^2+(-0.09-0.09)^2+(0.16-0.09)^2(0.21-0.09)^2(0.03-0.09)^2}{5-1}\\ V=0.01445$

c. Standard deviation.

$s = \sqrt{V} \\s= \sqrt{0.01445}\\s=0.1202 = 12.02\%$
