The lifetime of a certain type of battery is normally distributed with mean value 11 hours and standard deviation 1 hour. There
victus00 [196]

Answer: The required lifetime value is 11.27.

Step-by-step explanation:

Since we have given that

Mean value = 11 hours

Standard deviation = 1 hour

The total lifetime of all batteries in a package exceeds that value for only 5% of all packages.

So, α = 0.95, z= 1.645

n = 9

So, the lifetime value would be

x=\mu+z\times \dfrac{\sigma}{\sqrt{n}}\\\\x=11+1.645\times \dfrac{1}{\sqrt{36}}\\\\x=11+1.645\times \dfrac{1}{6}\\\\x=11.27

Hence, the required lifetime value is 11.27.

5 (x + 2 ) + 6 ( x - 3 ) = 25+
lapo4ka [179]
5(x + 2) + 6(x - 3) = 25

Simplify.

5x + 10 + 6x - 18 = 25

Add like terms.

(5x + 6x) + (10 - 18) = 25

Simplify.

11x - 8 = 25

Add 8 to both sides.

11x = 25 + 8

Simplify.

11x = 33

Divide both sides by 11.

x = 3
