Answer:

x=10

Step-by-step explanation:

3x−8=22

Step 1: Add 8 to both sides.

3x−8+8=22+8

3x=30

Step 2: Divide both sides by 3.

$\frac{3x}{3}$ = $\frac{30}{3}$

x=10

Answer:

x=10

Verification:Just substitute the x for 10

$3(10)-8=22$

Multiply 3 (10)

$30-8=22$

Substract 30-8

$22=22$ The solution is correct.

The correct answer is x=10

I hope this help :)

Examine the system of equations.

11Alexandr11 [23.1K]

<h3><u>Explanation</u></h3>

Given the system of equations.

$y = - \frac{1}{4} x - 2 \\ x = 4$

Substitute x = 4 in the first equation.

$y = - \frac{1}{4} (4) - 2 \\ y = - 1 - 2 \\ y = - 3$

We have both x and y values. Therefore, we can answer in coordinate point form.

<h3><u>Answer</u></h3>

<u> $\large \boxed{(4, - 3)}$ </u>

A firm’s marketing manager believes that total sales for next year will follow the normal distribution, with a mean of $3.2 mill

klasskru [66]

Answer:

The sales level that has only a 3% chance of being exceeded next year is $3.67 million.

Step-by-step explanation:

When the distribution is normal, we use 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.

In this question, we have that:

In millions of dollars,

$\mu = 3.2, \sigma = 0.25$
