A normally distributed population has a mean of 500 and a standard deviation of 60. Determine the probability that a random sample of size 16 selected from this population will have a sample mean less than 475. A. 0.3251 B. 0.0712 C. 0.7124 D. 0.0475

Answers

Answer:

D

Step-by-step explanation:

We start out by calculating the z-score

z = (x-mean)/SD/√n

x = 475

mean = 500

SD = 60

n = 16

Substituting these;

z = (475-500)/60/√16

z = (-25)/60/4

z = -25/15

z = -1.67

So the probability we want to

calculate is P (x < -1.67)

we can use the standard normal distribution table here;

And from the standard normal distribution table;

we have P( x < -1.67) as 0.04746

which is approximately 0.0475

The probability that this population will have a sample mean less than 475 is 0.0475

z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } \\\\where\ \mu=mean,\sigma=standard\ deviation,x=raw\ score,n=sample\ size[/tex]

Given that n = 16, μ = 500, σ = 60.

For x < 475:

[tex]z=\frac{475-500}{60/\sqrt{16} } =-1.67[/tex]

From the normal distribution table, P(x < 475) = P(z < -1.67) = 0.0475

The probability that this population will have a sample mean less than 475 is 0.0475

The salaries of Kofi and Ama are in the ratio 3:5. If the salary of each is raised by ¢4000, the new ratio becomes 40:57. what is Ama's salary​

Answers

Answer:

34000

Step-by-step explanation:

New Ratio = 40/57

Gap between numerator & denominator = 17

Original Ratio = 2/3

Gap between numerator & denominator = 1

=> Original Ratio can be restated as 34/51 to make gap of both ratios same.

Difference between two numerators OR denominators = 40 - 34 = 6 or 57 - 51 = 6

If gap is 6, sumit’s original salary = 51

If gap = 4000, sumit’s original salary is :

51/6 x 4000 = 34000

The salary of Amma is given as ¢11724.10.

What is the application ratio and proportion?

A ratio is the relation between two numbers as a / b. A proportion is the equality of two ratios as a / b = c / d.

Ratio and proportion can be applied to solve Mathematical problems dealing with unit values of the quantities.

The ratio of the salaries of  Kofi and Ama is given as 3 : 5.

After adding 4000 to each ratio the new ratio becomes as 40 : 57.

Suppose the present salaries of  Kofi and Ama be 3x and 5x respectively.

Then, as per the question following equation can be written as,

(3x + 4000)/(5x + 4000) = 40/57

=> 57(3x + 4000) = 40(5x + 4000)

=> 200x - 171x = 68000

=> 29x = 68000

=> x = 68000/29

       = 2344.82

The Amma's salary is given by,

5x = 5 × 2344.82

    = 11724.10

Hence, Amma's present salary is given as ¢11724.10.

Use appropriate algebra and Theorem 7.2.1 to find the given inverse Laplace transform. (Write your answer as a function of t.) ℒ−1 s (s − 4)(s − 5)(s − 20)

Answers

Answer:

[tex]L^{-1} \begin {pmatrix} \dfrac{s}{((s-20)(s-5)(s-4)} \end {pmatrix}= \dfrac{e^{4t}}{12}\begin {pmatrix}e^{16t} - 4e^t+3 \end {pmatrix}[/tex]

Step-by-step explanation:

From the given information the first step to carry out is to find the partial fraction of the given equation; i.e.

[tex]\dfrac{s}{(s-4)(s-5)(s-20)}= \dfrac{A}{s-4}+\dfrac{B}{s-5}+\dfrac{C}{s-20}[/tex]

After finding the partial fraction; we get:

[tex]s= s^2(A+B+C)+s(-2A-24B-25C)+20A+80B+100C[/tex]

By solving this; we get:

[tex]A =\dfrac{1}{12}\ ; \ B = -\dfrac{1}{3} \ ; \ C= \dfrac{1}{4}[/tex]

Thus;  the above equation can be re-written as:

[tex]\dfrac{s}{(s-20)(s-5)(s-4)}= \dfrac{\dfrac{1}{12}}{s-20}+\dfrac{-\dfrac{1}{3} }{s-5}+\dfrac{\dfrac{1}{4}}{s-4}[/tex]

Finally as a function of t ;

[tex]L^{-1} \begin {pmatrix} \dfrac{s}{((s-20)(s-5)(s-4)} \end {pmatrix}= \dfrac{e^{4t}}{12}\begin {pmatrix}e^{16t} - 4e^t+3 \end {pmatrix}[/tex]

You are conducting an experiment to evaluate how the number of hours spent exercising each week affects blood pressure. What is the independent variable in this experiment

Answers

Answer:

The question is incomplete, below is the complete question

You are conducting an experiment to evaluate how the number of hours spent exercising each week affects blood pressure. What is the independent variable in this experiment?

The intensity of the exercise.

The amount of exercise each week.

Blood Pressure

The type of exercise.

Answer:

The amount of exercise each week.

Step-by-step explanation:

The two major kinds of variables in a scientific experiment are the independent and dependent variables.

The independent variable is the variable whose values are completely under the complete manipulation of the experimenter. The experimenter decides what value to assign to the variables in this category and the effect of the manipulation of the independent variable determines the outcome variable. In this example, the amount of exercise each week, which is determined by the number of hours exercised each week is subject to the experimenter, hence it is the independent variable

The dependent or outcome variable is the variable whose values depend on the effect of the manipulation of the independent variable. This variable is not directly subject to the manipulation of the experimenter. In this example, the blood pressure gotten after the exercise is the outcome variable.

The variables in an experiment can be dependent or independent

The independent variable in the experiment is: the amount of exercise each week.

From the question, the parameters are:

Exercise intensity  Amount of exercise each week.  Blood Pressure Type of exercise.

For a variable to be considered as the independent variable, then the variable is not influenced by other variables or parameters.

Within the scope of this question, the independent variable is the weekly amount of exercise
