How do you solve the equation 3w-(-4)=8-w

Find the distance between -3 and 6 on a number line

docker41 [41]

-3, -2, -1, 0, 1, 2, 3, 4, 5, 6

The distance would be 9.

I apologize if I’m wrong, I’m not great at math :v

Solve the equation using square roots.<br><br> 2^2 - 26x + 169 = -13

shepuryov [24]

Answer:

x=13+√-13 or x=13-√-13

Step-by-step explanation:

Using the method of completing the square roots:

x²-26x=-13-169

x²-26x=-182

x²-26x+(-13)²=-182+(-13)²

(x-13)²=-182+169

(x-13)²=-13

Take square roots of both sides

(x-13)=√-13

x=13±√-13

That can also be written as

X=13+√13i,13-√13i

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 z-score 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 p-value, we get the probability that the value of the measure is greater than X.

Researchers found that the average student loan balance per borrower is $23,300.

This means that $\mu = 23300$

They also reported that about one-quarter of borrowers owe more than $28,000.

This means that the 1 subtracted by the p-value of Z is 0.25 when X = 28000, that is, when X = 28000, Z has a p-value of 0.75, so when X = 28000, Z = 0.675. We use this to find $\sigma$

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

$0.675 = \frac{28000 - 23300}{\sigma}$
