Question Help Suppose that the probability that a randomly selected person who has recently married for the first time will be divorced within 2 years is 0.25​, and that the probability that a randomly selected person who has recently married for the second time will be divorced within 2 years is 0.5. Take a random sample of 25 people married for the first time and 25 people married for the second time. The sample is chosen such that no one in the sample is married to anyone else in the sample. Why is the binomial model inappropriate for finding the probability that exactly 4 of the 50 people in the sample will be divorced within 2 ​years? List all of the binomial conditions that are not met.

Answers

Answer:

The trial are not dependent

Step-by-step explanation:

The following four conditions must be met before Binomial probability experiment can be define, they are:

[1]. Each trial is independent, [2]. the trial must have two outcomes that is failure or success, [3]. fixed number of trials and [4]. success probability for each trial is the same.

Thus, the number of ways to choose the positions for success is given in equation (1) below as:

P(x) = n Cₓpˣ [1 - p]ⁿ⁻ˣ. ----------------------------------------------------------------------(1).

Where n-x = failure and 1 - p = probability and x = success.

For this question, three of the conditions mentioned above are met except for condition number one. This is so because the events are dependent. Therefore, the binomial condition that is not met is Each trial is independent.

NB: Why the events are dependent is because if the each husband divorce his wife, then the wife is also divorced.

If I’m not mistaken the answer will be 15.

explanation:

20 = 2(n - 3)

•first distribute
2xn= 2n
2x-3= -10

20 = 2n - 10

•add 10 to both sides (since the sign is negative do the opposite.)

30 = 2n

•divide both sides by 2.

Find the remainder of
[tex] \frac{ {2021}^{2021} }{19} [/tex]
​

Answers

Divide 2021 by 19:

2021/19 = 106.3684 = 106 * 19 + 7

Now calculate the remainder of 7^2021

7^1 = 7

7^2 = 49 = 2*19 + 11

7^3 = 343 = 18*19 + 1

7^4 = 2394* 19 + 7

The pattern repeats 7, 11 , 1

So for every time the exponent is increased by 10, the remainder is is the same. ( so a starting value of 1 would have a remainder of 7.

This means the remainder of 2021^2021/19 would be 7

Answers

9514 1404 393

Answer:

2 6/11 days1 2/3 hours

Step-by-step explanation:

1. Add the rates in terms of houses per day.

  1/4 + 1/7 = (7+4)/28 = 11/28

Then the time required in terms of days per house is the reciprocal of this:

  28/11 = 2 6/11 . . . . days to paint a house, working together

__

2. Each hour, the vehicles separate by 55 -40 = 15 miles. Then the time required for a separation of 25 miles is ...

  time = distance/speed = (25 mi)/(15 mi/h_ = 5/3 h = 1 2/3 h

The vehicles will be separated by 25 miles after 1 2/3 hours.

Rectangle is 5 feet wide and 11 feet long. What is the perimeter

Answers

Answer:

Just add all side

5+11+5+11=32 feet

Make w = width

Since the length is 5 times the width, L = 5w

The formula for perimeter is
P = 2L + 2w

Since the perimeter is 48 and L = 5w
P = 2L + 2w
48 = 2(5w) + 2w
48 = 12w
