The amount of soda in a 16-ounce can is normally distributed with a mean of 16 ounces and a standard deviation of 0.20 ounce. What percentage of these cans will have less than 15.6 ounces

Answers

Answer: The percentage of these cans will have less than 15.6 ounces = 2.28%

Step-by-step explanation:

Let x = amount of soda in a 16-ounce can which  is normally distributed.

[tex]\mu=16\text{ ounces},\ \ \ \ \sigma=0.20\text{ ounces}[/tex]

The probability that cans will have less than 15.6 ounces:

[tex]P(X<15.6)=P(\dfrac{X-\mu}{\sigma}<\dfrac{15.6-16}{0.20})\\\\=P(z<-2)=1-P(Z<2)\\\\=1-0.9772\ \ \ [\text{By p-value table}]\\\\=0.0228=2.28\%[/tex]

Hence, the percentage of these cans will have less than 15.6 ounces = 2.28%

Medical records indicate that people with more education tend to live longer; the correlation is 0.48. The slope of the linear model that predicts lifespan from years of education suggests that on average people tend to live 0.8 extra years for each additional year of education they have. The slope of the line that would predict years of education from lifespan is

Answers

Answer:

0.288

Step-by-step explanation:

Given that :

Correlation (R) = 0.48

Slope of linear model which predicts Lifespan from years of education (m) = 0.8

To determine the value of slope of the model which predicts years of eductauoon from lifespan:

The square of the regression Coefficient is multiplied by the inverse of the slope of linear model which predicts Lifespan from years of education

Hence,

(R² * 1/m)

0.48² * 1/0.8

0.2304 * 1.25

= 0.288

Find constants A and B such that the function y = A sin(x) + B cos(x) satisfies the differential equation y'' + y' − 2y = sin(x).

Answers

Answer:

A = - 0.3 and B = - 0.1.

Step-by-step explanation:

y(x) = A sinx + B cosx

y'(x) = A cosx - B sinx

y"(x) = -A sinx - B cos x

So, substituting we have:

y" + y' - 2y = -A sinx - B cos x + A cosx - B sinx - 2(A  sinx + B cosx)

=    -3A sin x - B sinx + A cosx  - 3B cos x = sinx

sin x (-3A - B) + cos x(A - 3B) = sin x

Since this is an identity then we equate coefficients:

-3A - B =  1

A - 3B = 0

Solving these we get A = - 0.3 and B = - 0.1.

The amount of tax for another camera is $5.25 and the tax rate is 6%. Use the given equation to find the price before tax.

Answers

Answer:

0.31 *rounded to the nearest thousendth.*

Step-by-step explanation:

$5.25*6/100=Your tax

Answer:

$ 87.50

Step-by-step explanation:

First, identify what is given from the problem:

Tax Amount = $5.25

Tax Rate = 6%

Original Cost  = ?

Then let us state the original formula stated from the problem.

Tax Amount = (Original Cost)(Percent)

Since the Percent in our equation is the Tax Rate, let us substitute it to avoid confusion.

Tax Amount = (Original Cost)(Tax Rate)

The Original cost is the only unknown in this equation as stated from the given. Now we need to arrange first the equation so that the unknown should be on the left side.

(Original Cost)(Tax Rate) = Tax Amount  

To remove the Tax Rate to be multiplied to the Original Cost, let us divide both side by the same Tax Rate. This holds true to all as long as what you did on the left side of the equation should be done on the right side of the equation.

(Original Cost)(Tax Rate) / (Tax Rate) = (Tax Amount) / (Tax Rate)

This will cancel the Tax Rate on the left side of the equation to yield to a new formula for the Original Cost.

Original Cost = (Tax Amount) / (Tax Rate)

We can then substitute the values to solve the problem

Original Cost = $ 5.25 / 0.06

Original Cost = $ 87.50

Therefore the original price before tax is $ 87.50

1. The time between arrivals of taxis at a busy intersection is exponentially distributed with a mean of 10 minutes. a. What is the probability that you wait longer than one hour for a taxi

Answers

Answer:

The answer is below

Step-by-step explanation:

The time between arrivals of taxis at a busy intersection is exponentially distributed with a mean of 10 minutes. (a) What is the probability that you wait longer than one hour for a taxi? (b) Suppose that you have already been waiting for one hour for a taxi. What is the probability that one arrives within the next 10 minutes? (c) Determine x such that the probability that you wait more than x minutes is 0.10. (d) Determine x such that the probability that you wait less than x minutes is 0.90.

Answer:

A continuous variable is has a probability distribution function as:

[tex]f(x)=\lambda e^{-\lambda x}[/tex]

A continuous variable is has a cumulative distribution function as:

[tex]F(x)=1- e^{-\lambda x}[/tex]

Given mean  = 10 minutes

[tex]mean=\frac{1}{\lambda}\\ \\10=\frac{1}{\lambda}\\\\\lambda=\frac{1}{10}[/tex]

a) P(X > 1 hour) = P(X > 60 minutes) = 1 - F(60) = [tex]1-[1-e^{-60*0.1}]=0.0025[/tex]

b) P(X < 70 | x > 60) = P(X < 10) = [tex]1-e^{-10*0.1}=0.6321[/tex]

c) 0.1 = P(X > x)

0.1 = 1 - F(x)

[tex]0.1=1-[1-e^{-0.1*x}\\\\0.1=e^{-0.1x}\\\\ln(0.1)=-0.1x\\\\-2.3=-0.1x\\\\x=23\ minutes[/tex]

d) 0.9 = P(X < x)

0.9 = F(x)

[tex]0.9=1-e^{-0.1*x}\\\\e^{-0.1x}=1-0.9\\\\e^{-0.1x}=0.1\\\\ln(0.1)=-0.1x\\\\-2.3=-0.1x\\\\x=23\ minutes[/tex]

. The probability of drawing a blue cube from a hat is 80%. What is the probability of drawing 4 blue cubes in a row

Answers

Given:

The probability of drawing a blue cube from a hat is 80%.

To find:

The probability of drawing 4 blue cubes in a row.

Solution:

Let E be the event of drawing a blue cube from a hat.

[tex]P(E)=80\%[/tex]

[tex]P(E)=\dfrac{80}{100}[/tex]

[tex]P(E)=0.8[/tex]

We need to find the probability of drawing 4 blue cubes in a row.

Let as consider each cube is replaced after being drawn. So, that probability of drawing a blue cube from a hat remains same.

Probability of drawing 4 blue cubes in a row is

[tex]P(E)\times P(E)\times P(E)\times P(E)=(P(E))^4[/tex]

                                                          [tex]=(0.8)^4[/tex]

                                                          [tex]=0.4096[/tex]

Therefore, the required probability is 0.4096.

A soft drink machine outputs a mean of 24 ounces per cup. The machine's output is normally distributed with a standard deviation of 3 ounces. What is the probability of filling a cup between 18 and 30 ounces

Answers

Answer:

The probability is 0.9545

Step-by-step explanation:

We start by using z-scores here

Mathematically;

z-score = (x-mean)/SD

mean = 24 ounces

SD = 3 ounces

For 18, we have

z-score = (18-24)/3 = -6/3 = -2

For 30, we have

z-score = (30-24)/3 = 6/3 = 2

So the probability we want to calculate is;

P( -2 < x < 2)

We can use the standard normal distribution table for this

From the standard normal distribution table;

P(-2 < x < 2) = 0.9545

The U.S. Bureau of Labor Statistics released hourly wage figures for various countries for workers in the manufacturing sector. The hourly wage was $30.67 for Switzerland, $20.20 for Japan, and $23.82 for the U.S. Assume that in all three countries, the standard deviation of hourly labor rates is $3.00. Appendix A Statistical Tables a. Suppose 36 manufacturing workers are selected randomly from across Switzerland and asked what their hourly wage is. What is the probability that the sample average will be between $30.00 and $31.00?

Answers

Answer:

The probability that the sample average will be between $30.00 and $31.00 is 0.6553.

Step-by-step explanation:

Let X represent the hourly wage for Switzerland.

It is provided that the mean hourly wage for Switzerland was $30.67 and the standard deviation of hourly labor rates is $3.00.

A random sample of 36 manufacturing workers are selected randomly from across Switzerland and asked what their hourly wage.

According to the Central Limit Theorem if an unknown population is selected with mean μ and standard deviation σ and appropriately huge random samples (n > 30) are selected from this population with replacement, then the distribution of the sample means will be approximately normally.  

As n = 36 > 30, Central limit theorem is applicable.

Then, the mean of the sample means is given by,

[tex]\mu_{\bar x}=\mu=30.67[/tex]

And the standard deviation of the sample means is given by,

[tex]\sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}=\frac{3}{\sqrt{36}}=0.50[/tex]

Compute the probability that the sample average will be between $30.00 and $31.00 as follows:

[tex]P(30<\bar X<31)=P(\frac{30-30.67}{0.50}<\frac{\bar X-\mu_{\bar x}}{\sigma_{\bar x}}<\frac{31-30.67}{0.50})[/tex]

                         [tex]=P(-1.34<Z<0.66)\\\\=P(Z<0.66)-P(Z<-1.34)\\\\=0.74537-0.09012\\\\=0.65525\\\\\approx 0.6553[/tex]

Thus, the probability that the sample average will be between $30.00 and $31.00 is 0.6553.
