Your company offers warranty coverage for MP3 players. The policy provides for the replacement of MP3 players that fail within 3

Finger [1]

Answer:

181 MP3 players

Step-by-step explanation:

Given data:

Replacement of MP3 that fail within 3 years

expected lifetime of MP3 = 5 years

number of MP3 players purchased = 1000

number of MP3 players replaced in the first year = ?

To determine the number of MP3 replaced in the first year we will employ this formula:

$E(To) = \frac{1}{u} = e_{x} ^{0} =\int\limits^a_0 {po} \, dt$

a = ∞

since the given problem is an exponential distribution

1/u = 5 hence u = 0.2

next we will determine the number of MP3's to fail in its first year of purchase

qo = failure

po = success

number of purchase = 1000

attached below is the remaining part of the solution

Simplify fully: X^2+3x-4/ 2x^2-5x+3

sweet-ann [11.9K]

Answer:

(-x - 3) • (x - 1)

Step-by-step explanation:

Step 1 :

2

Simplify —

1

Equation at the end of step 1 :

((((x2)+3x)-(2•x2))-5x)+3

Step 2 :

Equation at the end of step 2 :

((((x2) + 3x) - 2x2) - 5x) + 3

Step 3 :

Step 4 :

Pulling out like terms :

4.1 Pull out like factors :

-x2 - 2x + 3 = -1 • (x2 + 2x - 3)

Trying to factor by splitting the middle term

4.2 Factoring x2 + 2x - 3

The first term is, x2 its coefficient is 1 .

The middle term is, +2x its coefficient is 2 .

The last term, "the constant", is -3

Step-1 : Multiply the coefficient of the first term by the constant 1 • -3 = -3

Step-2 : Find two factors of -3 whose sum equals the coefficient of the middle term, which is 2 .

-3 + 1 = -2

-1 + 3 = 2 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -1 and 3

x2 - 1x + 3x - 3

Step-4 : Add up the first 2 terms, pulling out like factors :

x • (x-1)

Add up the last 2 terms, pulling out common factors :

3 • (x-1)

Step-5 : Add up the four terms of step 4 :

(x+3) • (x-1)

Which is the desired factorization

Final result :

(-x - 3) • (x - 1)
