Answer:

f/2 = -20

f = -10

Step-by-step explanation:

1. Subtract 9 on both sides

f/2 + 9 -9 = 4 -9

= f/2 = -5

2. Multiply all terms by the same value to eliminate fraction denominators

2* f/2 = 2(-5)

3. Simplify

f = -10

The delivery times for all food orders at a fast-food restaurant during the lunch hour are normally distributed with a mean of m
UkoKoshka [18]

Answer:

Let X the random variable that represent the delivery times of a population, and for this case we know the distribution for X is given by:

X \sim N(14.7,3.7)  

Where \mu=14.7 and \sigma=3.7

Since the distribution of X is normal then we know that the distribution for the sample mean \bar X is given by:

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

And we have;

\mu_{\bar X}= 14.70

\sigma_{\bar X} =\frac{3.7}{\sqrt{40}}= 0.59

Step-by-step explanation:

Assuming this question: The delivery times for all food orders at a fast-food restaurant during the lunch hour are normally distributed with a mean of 14.7 minutes and a standard deviation of 3.7 minutes. Let R be the mean delivery time for a random sample of 40 orders at this restaurant. Calculate the mean and standard deviation of \bar X Round your answers to two decimal places.

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 delivery times of a population, and for this case we know the distribution for X is given by:

X \sim N(14.7,3.7)  

Where \mu=14.7 and \sigma=3.7

Since the distribution of X is normal then we know that the distribution for the sample mean \bar X is given by:

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

And we have;

\mu_{\bar X}= 14.70

\sigma_{\bar X} =\frac{3.7}{\sqrt{40}}= 0.59

pedro earned gross income of 35200 last year. if he took the standard deduction of 5450 and one exemption of 3500, what was his
Elenna [48]

Answer:

33250

Step-by-step explanation:

Pedro had earned a gross income of 35200 last year.

So, the gross income of Pedro for the current year will also be 35200.

But, this year he has taken the standard deduction of 5450.

Hence, his current year's income will be reduced to (35200-5450)= 29750.

Again, in the current year, he got an exemption of 3500.

Therefore, the net taxable income of Pedro for the current year will become (29750+3500) =33250. (Answer)

Solve the following equation.
elena-14-01-66 [18.8K]

Answer:

x=6

Step-by-step explanation:

x + 6 = x + x        original problem

x + 6 = 2x            combine like terms

-x      = -x             subtract x from both sides to have like terms on each side

6 = x                    solution
