Answer:

Step-by-step explanation:

1) (x-3),(x-8)

2) 3x^3+3x^2=27x

3 ( x 3^3+ x ^2 − 9 x − 9 )

3 ( x ^2 ( x + 1 ) − 9 ( x + 1 ) )

3 ( ( x + 1)( x ^2 − 9 ) )

3 ( ( x + 1 ) ( x ^2 − 3 ^2 ) )

3 ( x + 1 ) ( x + 3 ) ( x − 3 )

Michelin Tire Company wishes to set a minimum mileage guarantee on its new MX100 tire. Tests reveal the mean mileage is 67,900 w

Keith_Richards [23]

Answer:

The minimum guaranteed mileage is $x = 71489.55$

Step-by-step explanation:

From the question we are told that

The mean is $\mu = 67900$

The standard deviation is $\sigma = 2050$

Generally for the probability to be 4% the minimum guaranteed mileage is evaluated as

$P( X \ge x ) =1- P( \frac{X - \mu }{\sigma } < \frac{ x - 67900 }{ 2050} ) = 0.04$

$\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )$

$P( X \ge x ) =1- P( Z$

=> $P( X \ge x ) = P( Z$

=> $z = \frac{ x - 67900 }{ 2050}$

From the z table, the critical value corresponding to 0.96 to the left of the curve is

$z = 1.751$

$1.751 = \frac{ x - 67900 }{ 2050}$

=> $x = 71489.55$
