<h2>Answer:</h2>

William Jones

<h2 /><h2>Step-by-step explanation:</h2>

The number pi (π) is a platonic concept and has been used for 4000 years. The number pi can be approached but never reached. In general, this number means the constant ratio of the circumference to the diameter of any circle. Ancient Babylonians, Egyptians, and even Archimedes, one of the greatest mathematicians of the ancient world tried to approximate the value of pi, but in the 1700s, mathematicians began using the Greek letter π that was introduced by William Jones, in his second book <em>Synopsis Palmariorum Matheseos</em> or <em>A New Introduction to the Mathematics base</em>. Then, this symbol was popularized and adopted in 1737 by the greatest mathematician Leonhard Euler.

Let X be a discrete random variable with geometric distribution.
Let x be the number of tests and p the probability of success in each trial, then the probability distribution is:
P (X = x) = p * (1-p) ^ (x-1). With x = (1, 2, 3 ... n).
This function measures the probability P of obtaining the first success at the x attempt.
We need to know the probability of obtaining the first success at the third trial.
Where a success is defined as a customer buying online.
The probability of success in each trial is p = 0.3.
So:
P (X = 3) = 0.3 * (1-0.3) ^ (3-1)
P (X = 3) = 0.147
The probability of obtaining the first success at the third trial is 14.7%

Nicholas borrowed $250 from his parents to buy a video game system. He has agreed to pay them back $15 each week. Which equation

AfilCa [17]

Answer:

p = 250 - 15(w)

Step-by-step explanation:

Original amount: 250

No of weeks to return money: w

Amount to pay each week: 15

Amount that he has paid back: 15 × w (When we subtract this term from the total we will get the answer)

So after w weeks he owes his parents :

p = 250 - 15(w)

It took Margie 2 1/4hours to write a 1 1/2 page research paper . What was her hourly writing rate

WARRIOR [948]

Margie would take 1 hour and 30 minutes to write 1 page of her research paper. Think of it like a proportion:

2.25/ 1.5 = x/1

2.25 is the 2 1/4 converted which is the amount of hours she took.

1.5 is the 1 1/2 converted which are the amount of pages she wrote total.

1 on the right side of the proportion represents 1 page.

And x are the amount of hours used to write 1 page.

And in solving that proportion it would result in 1.5 or 1hr. and 30 min.

5p−m=10 answer my question

nasty-shy [4]

Answer:

m = -10 + 5p

Step-by-step explanation:

5p − m = 10

subtract 5p from both sides:

5p − m - 5p = 10 - 5p

simplifiy:

-m = 10 - 5p

divide -1 to both sides

m = -10 + 5p

m = -10 + 5p

what is the difference between the mean and the median of the following distribution? {1,1,1,2,2,2,2,3,3,4,4,4,4,5,5,6,7,7,8,8,9

iren2701 [21]

The given distribution =

1, 1, 1, 2, 2, 2, 2, 3, 3, 4, 4, 4, 4, 5, 5, 6, 7, 7, 8, 8, 9

To find mean, we have to add the given numbers and divide it by the total number of terms given.

Here 21 total numbers given.

Mean = (1+1+1+2+2+2+2+3+3+4+4+4+4+5+5+6+7+7+8+8+9) /21

= (88)/21 = 4.19 (Approximate upto two decimal place)

Median is the middle value of the distribution.

1, 1, 1, 2, 2, 2, 2, 3, 3, 4, 4, 4, 4, 5, 5, 6, 7, 7, 8, 8, 9

There are 21 numbers given. So middle value is the number in the 11th position.

The number in the 11th position is 4.

So, the median of the distribution = 4

We have to find the difference between mean and median here. To find the difference we have to subtract mean and median.

Therefore, the required difference = 4.19 - 4 = 0.19

0.19 is the required answer here.

So, option b is correct.
