x^2 - 8x + 12 = 0\\
x^2-2x-6x+12=0\\
x(x-2)-6(x-2)=0\\
(x-6)(x-2)=0\\
x=6 \vee x=2

A machine fills boxes with cereal. The boxes are labeled as containing 24 ounces but there is some variability; the amount depos
m_a_m_a [10]

Answer:

The mean amount of cereal in a box must be 23.42 ounces.

Step-by-step explanation:

Let <em>X</em> = amount of cereal in a box.

It is provided that <em>X</em> follows a normal distribution with mean <em>μ</em> and standard deviation <em>σ</em> = 0.25.

If 99% of the boxes contain 24 ounces or more of cereals then the probability statement is:

\geq P(X \geq 24) = 0.99\\P(\frac{X-\mu}{\sigma}\geq  \frac{24-\mu}{0.25})=0.99\\P(Z \geq z)=0.99\\1-P(Z

Use the <em>z</em> table to determine the <em>z-</em>value.

The value of <em>z</em> is -2.33.

Determine the value of <em>μ</em> as follows:

\frac{24-\mu}{0.25}=-2.33 \\\mu=24-(2.33\times 0.25)\\=23.4175\\\approx23.42

Thus, the mean amount of cereal in a box must be 23.42 ounces.
