$\huge\boxed{y=\frac{3}{2}x-1}$

Start with the slope-intercept formula.

$y=mx+b$

In this formula, $m$ is the slope and $b$ is the y-intercept.

Substitute in the slope.

$y=\frac{3}{2}x+b$

Substitute in the y-intercept.

$y=\frac{3}{2}x+(-1)$

Adding a negative number is the same as subtracting the absolute value of that same number.

$y=\frac{3}{2}x-|-1|$

Find the absolute value.

$\large\boxed{y=\frac{3}{2}x-1}$

Answer:

y=3/2x+-1

Step-by-step explanation:

the formula is y=mx+b

y is the total

m is the slope

x is what you're multiplying the slope by

b is the y intercept

The town of Simpsonville has two tow truck companies. Company A charges an initial fee of $30 plus $2 per mile. Company B charge

V125BC [204]

Hello :) = Merhaba :)

Answer:

Step-by-step explanation:

In order to solve this question, we need to create an equation.

If A company initially supplies $30 and then $2 per mile, the equation:

2x+30 would.

If B company initially supplies $20 and then $4 per mile, the equation:

4x+20 would.

In the question, since these two wages are asked to be equalized, we equate these two equations with each other and find the result. The answer:

2x+30 = 4x+20

2x = 10

x = 5 would.

<h3 /><h3>The answer 5 would.</h3><h3 />

Sati [7]

Answer:

<h2>Approximately 8%</h2>

Step-by-step explanation:

If rounded by whole number. 

But without rounding it would be 8.3333333333%

Explanation: you have 30 days in a month so you do $250÷30 and you will get your results then round so it would be 8.3% if not rounded and 8% if rounded.

The Arc Electronic Company had an income of 59 million dollars last year. Suppose the mean income of firms in the same industry

Zolol [24]

Answer:

0.0228 = 2.28% probability that a randomly selected firm will earn more than Arc did last year

Step-by-step explanation:

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.

Suppose the mean income of firms in the same industry as Arc for a year is 45 million dollars with a standard deviation of 7 million dollars

This means that $\mu = 45, \sigma = 7$
