The random variable KK has a geometric distribution with mean 16. Which of the following is closest to the standard deviation of random variable KK ?
A. 0.0625
B. 0.9375
C. 4
D. 15.49
E. 240

Answers

Answer 1

Answer:

E 240

Step-by-step explanation:

Geometric Distribution mean = (1- p) / p

16 = (1 - p) / p

16p = 1 - p  ;  17p = 1 ; p = 1/17 = 0.058  

Standard Deviation = (1 - p) / p^2

= (1 - 0.058) / (0.058)^2

0.942 / 0.003364

= 280 , closest to 240

Answers

Answer:

1 1/8"

Step-by-step explanation:

First, make a common denominator.

1 1/4 = 5/4 * 2/2 = 10/8 = 1 2/8

Breakfast is frequently referred to as "the most important meal of the day," and with good cause. Breakfast, as the name implies, breaks the overnight fast. Along with providing other crucial nutrients needed for optimal health, it replaces your glucose supply to increase your energy and alertness.

There is medical evidence that eating breakfast is beneficial. In addition to helping you control your weight better, reducing your risk of type 2 diabetes and heart disease in the long run, it also boosts your energy levels and concentration capacity in the near term.

Answer: we have  2,200milliters, 1000milliters, 1800milliters.

Step-by-step explanation:

Step 1

1 Liter= 1000 millilitres

5 liters = 5000 millilitres

Step 2

Dividing 5000 ml in the ratio 11:5:9

First, we find the  Total ratio = 11+5+9 = 25

Such that

First  part = 11/25  x 5000 = 2,200milliters.

Second Part = 5/25 x 5000=1000milliters.

what is the range of the function f (x)= -1/3 lx-1l-2?​

Answers

Answer:

All real values less than or equal to -2 or (infinity, -2].

Step-by-step explanation:

The range of the function is the range of what the output can be. Let’s analyze the equation in parts.

Notice that |x-1| must always be greater than or equal to 0, so we know that 1/3|x-1| also must always be greater than or equal to 1/3*0 = 0.

With the negative, however, -1/3|x-1| must be less than or equal to -1/3*0 = 0.

Finally, we take the -2 into account. -1/3|x-1| - 2 must always be less than or equal to 0-2 = -2.

Therefore, the range is all real values less than or equal to -2, which can be written as (infinity, -2].

From a population of 200,000,000 elements, the standard deviation is known to be 14. A sample of 49 elements is selected. It is determined that the sample mean is 56. The standard error of the mean is

Answers

Answer:

The standard error of the mean = 2

Step-by-step explanation:

Given that:

The standard deviation σ = 14

The sample size n = 49

The sample mean [tex]\overline x[/tex] = 56

The formula for calculating the standard error can be expressed as:

[tex]S.E = \dfrac{\sigma}{\sqrt{n}}[/tex]

[tex]S.E = \dfrac{14}{\sqrt{49}}[/tex]

[tex]S.E = \dfrac{14}{7}[/tex]

S.E = 2

Answer:

x=3

Step-by-step explanation:

First start by simplifying the right side which is -5(x-8)+4. Apply the distributive property to have -5x-5*-8+4. Then simplify to -5x+40+4, and then to -5x+44. Now you are left with 14+5x = -5x+44. Move -5x to the left side, which now makes it positive, and do 5x+5x to have 14+10x=44. Now move 14 to the right side and subtract it from 44 to get 10x=30. Now divide both sides by 10 to have x=3.

Answer:

x=-5

Step-by-step explanation:

14 + 5x = -5(x-8)+4

14+5x=-5x+40+4

14+5x=-5x+44

14+10x=44

It is the end of the semester, and the clubs at school are recording their profits. Graph both lines from question 1 and 2 on the same coordinate plane. When do the clubs have the same balance?

Answers

Answer:

Science Club- y=10x+20

Math Club- y=5x+50

They will be equal 6 weeks

Step-by-step explanation:

X equals the number of weeks that have passed. In example of the science club, they would gain $10 every week, making the equation y (total money) equal to 10 dollars a week (or 10x.)

Since we know they begin with 20 dollars, we'll simply add that to the 10 dollars a week.

To find the week when they will be equal, we have to put both equations equal to each other.

10x+20=5x+50

Now we solve for x, or the number of weeks when the equations (and values) will be equal.

10x+20=5x+50

5x+20=50

5x=30

x=6

So... 6 weeks :)
