The cards are thoroughly reshuffled, and I again choose a card at random, observe its color, and replace it in the set. This is done a total of four times. Let X be the number of red cards observed in these four trials. The mean of X is:

Answers

Answer:

The mean of X is 2

Step-by-step explanation:

Given the data in the question;

set of 10 cards consist of 5 red card and 5 blacks

cards are chosen, replaced and shuffled four times;

number of independent trials n = 4

now, since its is replaced, the probability of getting a red card in each trial will be;

p = 5/10 = 0.5

let X rep the number of red cards observed in the four trials.

the random variable follows binomial distribution where

n = 4 and p = 0.5

E(X) = ∑xP( X = x )

E(X) = np

we substitute

E(X) = 4 × 0.5

E(X) = 2

Therefore, The mean of X is 2

This is because the diameter of the smaller circle is 12pi/pi which is 12, and the diameter of the bigger one is 18pi/pi which is 18. 12 + 6 = 18, so the diameter increases by 6.

Answer: I believe it’s 35
Explanation: so a triangle will always equal 180 add 104 19 and 22 and then subtract that by 180 and you get 35 hope this helps if not reply to my comment and I’ll help

Answer: z=35°

Explanation: First find X. All angles of a triangle adds up to 180°. To find x, add up all sides and set it equal to 180. 22+104+x=180. Solve for x. x = 54

A straight Line is 180°. Use x to find y. x+y = 180. Substitute x. 54+y=180 y = 126

To find z, find y + 19 +z = 180. Substitute y. 126+19+z=180. Solve for z. z = 35

A train arrives at a station and waits 3.5 minutes before departing. Another train arrives at the station 16 minutes later, repeating the cycle. Identify the probability that a train will not be at the station when you arrive.

Answers

Step-by-step explanation:

so we can safely say that one train will be there for 3.5 minutes and it will be gone for 16 minutes before another train comes and repeats the cycle.

we want how many minutes that the train will not be there over the total time that is possible so that would be

16/(16+3.5)

16/19.5

32/39

Hope that helps :)

The probability of the train not being at the station on arrival would be:

0.82

Find the probability

Given that,

The duration for which the train makes = 3.5 minutes

The time at which the second train arrives = 16 minutes later

We know that this cycle is repeated.

The duration for which the train is not there would be:

[tex]= 16/(16+3.5)[/tex]

[tex]= 16/19.5[/tex]

[tex]= 32/39[/tex]

[tex]= 0.82[/tex]

Thus, 0.82 is the probability.

how many ping pong balls do you need if you want to arrange them in the shape of an equilateral triangle with 23 rows

Answers

Answer:
You would need a total of 276 ping pong balls

Step by step explanation:
To determine the number of ping pong balls needed to form an equilateral triangle with 23 rows, we can calculate the total number of balls in the triangle. In an equilateral triangle, each row has one more ball than the previous row. The formula for the sum of the first n natural numbers is given by:

Sum = (n * (n + 1)) / 2

In this case, we want to find the sum of the first 23 natural numbers. Substituting n = 23 into the formula, we get:

Sum = (23 * (23 + 1)) / 2 = 276

Therefore, you would need 276 ping pong balls to arrange them in the shape of an equilateral triangle with 23 rows.
