A worker at a factory earns $12 per hour plus 2.50 for each unit produced that hour. The worker earns a total of $27 in one hour

nevsk [136]

Answer:

The total number of units produced is 6 .

Step-by-step explanation:

Given as :

The earning of worker at the factory = $ 12 per hour + $ 2.50 each unit per hour

The total earning of worker per hour = $ 27

Let The total number of unit produced = x

According to question

The wage worker earn per hour + earning × per unit produced that hour = Total earning of worker per hour

Or, $ 12 per hour + $ 2.50 each unit per hour × x = $ 27

Or, $ 2.50 each unit per hour × x = $ 27 - $ 12

Or, $ 2.50 each unit per hour × x = $ 15

∴ x = $\frac{15}{2.50}$

Or, x = 6

Hence The total number of units produced is 6 . Answer

A word processor that was purchased for $600

klasskru [66]

The slope of the graph shows the rate of change, or, in this case, the rate of depreciation, which you are told is $100 per year. So, depending upon the units used in your graph, the slope will be 100/1, and since it is a decrease as the years increase, it will have a negative slope, i.e. -100/1.

Or, if you had drawn your graph with units of $100 dollars on the y-axis, then you might say that the slope was -1 / 1.

The corresponding formula would of course be

y = 600 - 100t

where y = value after t years, and (if you are into calculus) differentiating would give you

slope = dy/dt = -100

Calculate the standard deviation of the distribution of sample means. Write you answer in terms of fluid ounces and round to thr

NikAS [45]

Answer:

$\sigma_{\bar X} =\frac{0.8}{\sqrt{8}}=0.283$

Step-by-step explanation:

Assuming this question : "A bottling plant fills one-gallon jugs with milk. The labels on the jugs state that the volume of milk they contain is 128 fluid ounces (fl. oz.). Federal law mandates that the jugs must contain no less than the stated volume. The actual volume of milk in the jugs is normally distributed with mean μ=129 fl. oz. and standard deviation σ=0.8 fl. oz. Plant workers take a simple random sample (SRS) of 8 jugs, measure the volume of milk in each jug, and calculate the sample mean".

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

Let X the random variable that represent the volume of milk in the jugs of a population, and for this case we know the distribution for X is given by:

$X \sim N(129,0.8)$

Where $\mu=129$ and $\sigma=0.8$

Since the distribution for X is normal then the distribution for the sample mean is given by:

$\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})$

And the standard deviation for the sample mean would be given by:

$\sigma_{\bar X} =\frac{0.8}{\sqrt{8}}=0.283$
