Answer:

option A.

$a^{9}b^{6}$

Step-by-step explanation:

To solve this, we need to use the following exponent rules:

Quotient rule: (a^n)/(a^m) = a^(n-m)

Power rule: (a^n)^m = a^nm

Power of a product rule: (ab)^n = (a^n)(b^n)

Then, we have the following expressions:

$[\frac{a^{-8}b}{a^{-5} b^{3}}}]^{-3}=[a^{-8+5}b^{1-3}}}]^{-3}=[a^{-3}b^{-2}]^{-3} =a^{9}b^{6}$

So the correct result is option A.

$a^{9}b^{6}$

The amount of soda a dispensing machine pours into a 12-ounce can of soda follows a normal distribution with a mean of 12.30 oun

Ugo [173]

Answer: A) .1587

Step-by-step explanation:

Given : The amount of soda a dispensing machine pours into a 12-ounce can of soda follows a normal distribution with a mean of 12.30 ounces and a standard deviation of 0.20 ounce.

i.e. $\mu=12.30$ and $\sigma=0.20$

Let x denotes the amount of soda in any can.

Every can that has more than 12.50 ounces of soda poured into it must go through a special cleaning process before it can be sold.

Then, the probability that a randomly selected can will need to go through the mentioned process = probability that a randomly selected can has more than 12.50 ounces of soda poured into it =

$P(x>12.50)=1-P(x\leq12.50)\\\\=1-P(\dfrac{x-\mu}{\sigma}\leq\dfrac{12.50-12.30}{0.20})\\\\=1-P(z\leq1)\ \ [\because z=\dfrac{x-\mu}{\sigma}]\\\\=1-0.8413\ \ \ [\text{By z-table}]\\\\=0.1587$
