Solve the equation by factoring: x^2 - 5x = 14
daser333 [38]

Answer:

x=7,  x=  -2

Step-by-step explanation:

  1. Start by putting the whole equation to one side:  x2-5x=14 ---->               x2-5x-14=0
  2. Next, factor the equation:  x,x    -7,2 ----> (x-7)(x+2)=0
  3. Now, solve both equations: x-7=0....x=7   AND   x+2=0.....x=  -2
  4. Plug both in to make sure that they are correct....both are correct

QUESTION 3 of 10: Stock returns vary from year to year. The more variance a stock displays the greater the potential risk. These
Dahasolnce [82]

Answer:

The variance of these investment returns is 74

Step-by-step explanation:

Given:

Series =  10, 30, 15, 5, 20

To Find:

variance of a series = ?

Solution:

The variance of the series = Var\left(X\right)=\sum _{i=1}^n\frac{\left(x_i-\bar{x}\right)^2}{n}

\bar{x} = \frac{10+30 +5+15 + 20}{5}

\bar{x} = \frac{80}{5}

\bar{x} =16

Now (x_i -\bar{x})^2 = (10 -16)^2 + (30 -16)^2 + (5 -16)^2 +(15 -16)^2 +(20 -16)^2

= (-6)^2 + (14)^2 + (-11)^2 + (-1)^2+ (-4)^2

= 36  + 196 +121 +  1+ 16

=  370

Now

Var\left(X\right)=\frac{370}{5} =  74

blagie [28]

Answer:

y =-3000x +12000

Step-by-step explanation:

answer is

1)   12000 is the constant therefore when the number of hours is 0 the tickets are 12000

2)  the number of tickets (y) are reducing by 3000 for each hour(x). thus the coefficient of variable x should be -3000  (negative because it is reducing)
