Slope -1/2, point (-4,-3) in slope int form

Aleksandr [31]

y = - $\frac{1}{2}$ x - 5

the equation of a line in slope-intercept form is

y = mx + c ( m is the slope and c the y-intercept )

here m = - $\frac{1}{2}$

y = - $\frac{1}{2}$ x + c ← is the partial equation

to find c substitute (- 4, - 3 ) into the partial equation

- 3 = 2 + c ⇒ c = - 3 - 2 = - 5

y = - $\frac{1}{2}$ x - 5 ← in slope-intercept form

The amount of cereal dispensed into "12-ounce" boxes of Captain Crisp cereal is normally distributed with mean 12.09 ounces and

wolverine [178]

Answer:

There is a 22.66% probability that the amount dispensed into a box is less than 12 ounces.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by

$Z = \frac{X - \mu}{\sigma}$

After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X.

In this problem:

The amount of cereal dispensed into "12-ounce" boxes of Captain Crisp cereal is normally distributed with mean 12.09 ounces and standard deviation 0.12 ounces, so $\mu = 12.09, \sigma = 0.12$ .
