PLEASE HELP!!!! Given the equation y = 2x - 8, what is the slope and the y-intercept?

2 answers:

By definition a line of the form y=mx+b tells you that the slope is m and the y-intercept is b, so by inspection, m=2 and b=-8

Y=mx+b
so m=2 and b=-8

g Consider a brand of coffee. The weight of a pod of coffee this brand makes has mean 42.05 grams and standard deviation 0.025 g

Brums [2.3K]

Using the normal distribution, it is found that there is a 0.0013 = 0.13% probability that the mean weight of 25 pods of coffee is less than 42.035 grams.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean $\mu$ and standard deviation $\sigma$ is given by:

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

The z-score measures how many standard deviations the measure is above or below the mean.

Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

The parameters are given as follows:

$\mu = 42.05, \sigma = 0.025, n = 25, s = \frac{0.025}{\sqrt{25}} = 0.005$

The probability that the mean weight of 25 pods of coffee is less than 42.035 grams is the <u>p-value of Z when X = 42.035</u>, hence:

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

$Z = \frac{42.035 - 42.05}{0.005}$

Z = -3

Z = -3 has a p-value of 0.0013.

0.0013 = 0.13% probability that the mean weight of 25 pods of coffee is less than 42.035 grams.

Which shows 602 − 402 being evaluated using the difference of squares method?

Elden [556K]

The right answer for the question that is being asked and shown above is that: "602 − 402 = (3600 + 1600)(3600 − 1600) = 10,400,000" The equation that shows 602 − 402 being evaluated using the difference of squares method is that <span>602 − 402 = (3600 + 1600)(3600 − 1600) = 10,400,000</span>
