Answer:

second option

Step-by-step explanation:

the average is calculated as

average = $\frac{sum}{count}$

= $\frac{4x+5+7x-6-8x+2}{3}$

= $\frac{3x+1}{3}$

= $\frac{3x}{3}$ + $\frac{1}{3}$

= x + $\frac{1}{3}$

Answer:

x + 1/3

Step-by-step explanation:

<u>It just basically the average of the three expressions</u>

<u>=> Remember to divide the expressions into 2 groups (the x group which contains x in it, and the numeral group which doesn't contains x)</u>

The x group: (4x + 7x + (-8x)) /3 = x

The numeral group: (5 +(-6) + 2) /3 = 1/3

So the answer must be x + 1/3, not x + 1

(I hope this is helpful)

MAVERICK [17]

Answer:

y+3=-6(x+8)

Step-by-step explanation:

Because we already know a point and the slope, we can put our equation in the form y-y1=m(x-x1);

y+3=-6(x+8)

Normal Probability Distribution:

Problems of normal distributions 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:

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

The Z-score measures how many standard deviations the measure is from the mean. 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, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Normally distributed with a mean of 5.8-in and a standard deviation of 0.8-in.

This means that $\mu = 5.8, \sigma = 0.8$
