What is the solution to the inequality (−4+8x)+3>x/−4 ?

Mathematics

NARA [144]3 years ago
4 0

(−4+8x)+3>x/−4

Remove the parenthesis and simplify the left side:

8x - 1 > x /-4

Add x/4 to each side:

8x + x/4 -1 > 0

Simplify the left side by combining 8x and x/4 as a fraction with a common denominator:

33x/4  -1 > 0

Add 1 to both sides:

33x/4 > 1

Multiply both sides by 4:

33x > 4

Divide both sides by 33:

x > 4/33

Find the solution to the system of equations. Write the solution as an ordered pair.
Greeley [361]
Answer:
Step-by-step explanation:
3x - 2y = –9
3x−2y+2y=−9+2y
3x=2y−9/3x^3
=2y−9/3
x=2/3y−3
4x + 3y = 22
4x+3y+−3y=22+−3y
4x=−3y+22
4x4
=−3y+22/4
x=−3/4y+11/2

A manufacturer makes chocolate squares that have a target weight of 8 g. Quality control engineers sample 30 chocolate squares t

Using the <em>normal distribution and the central limit theorem</em>, it is found that the power of the test is of 0.9992 = 99.92%.

<h3>Normal Probability Distribution</h3>

In a normal distribution with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

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

  • It 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, 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}}.

In this problem:

  • The mean is \mu = 8.5.
  • The standard deviation is \sigma = 0.87.
  • A sample of 30 is taken, hence n = 30, s = \frac{0.87}{\sqrt{30}} = 0.1588.

The power of the test is given by the probability of a sample mean above 8, which is <u>1 subtracted by the p-value of Z when X = 8</u>, so:

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

By the Central Limit Theorem:

Z = \frac{X - \mu}{s}

Z = \frac{8 - 8.5}{0.1588}

Z = -3.15

Z = -3.15 has a p-value of 0.0008.

1 - 0.0008 = 0.9992.

The power of the test is of 0.9992 = 99.92%.
