Two balls are picked in succession without replacement -4 white balls and 5 green balls let Y be the random representing the number of green balls. Find the value of the random variable Y.

Answers

Answer 1

Answer:

If Y represents the number of green balls then it can have values from 0- 5

that is it can have all the value  0,1,2,3,4 and 5.

The probability of getting both balss green without replacement is 0.27778

Step-by-step explanation:

If the balls are not replaced then this is the dependent event .

The probability of getting the first ball is given be = 5/9

where 5 is the number of green balls and 9 is the total number of balls.

The probability of getting the second ball green given that first is also green is  = 5/9* 4/8= 20/72= 0.2778

If Y represents the number of green balls then it can have values from 0- 5

that is it can have all the value  0,1,2,3,4 and 5.

0 means there can be no green balls or white balls.

1 means there can be one green ball.

2 means there can be 2 green balls and so on.

Answer 2

In this exercise we have to use the knowledge of probability to calculate the chance of an event to occur, so you have to:

the chance of the event is 0.2778%

So organizing the information given in the statement is:

If the balls are not replaced then this is the dependent event .The probability of getting the first ball is given be = 5/95 is the number of green balls and 9 is the total number of balls.

So with this information we can write that:

[tex]5/9* 4/8= 20/72= 0.2778[/tex]

Paula is going to hire a makeup artist for a fashion show and is comparing prices. Shelley charges $40 as a booking fee and an additional $30 per hour. Ezra charges $35 per hour, plus a booking fee of $30. Depending on the length of the show, the cost could end up being the same for either artist. What would the cost be?​

The cost of booking was $100 as obtained by the length of the show.

What are linear and non-linear functions?

A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x – 2 depicts a linear function because it is a straight line in the coordinate plane.

Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.

An example of a non-linear function is a quadratic function.

From the given information the two linear equations can be formed as,

30x + 40 and 35x + 30.

The cost would be the same when we'll equate these two equations.

30x + 40 = 35x + 30.

30x - 35x = 30 - 40.

- 5x = - 10.

5x = 10.

x = 10/5.

x = 2, So at two hours the cost would be the same and the total cost is,

$30(2) + 40.

$60 + 40.

= $100.

HELP! Please answer fast How many terms are in the geometric series 0.4 + 1.2 + 3.6 + ... + 7,873.2?

Answers

Answer:

10 terms. I think you should check the explanation :)

Step-by-step explanation:

0.4 + 1.2 + 3.6 + ... + 7,873.2?

So I figured that you have to multiply the terms by three to get the next term.

0.4 * 3 = 1.2

1.2 * 3 = 3.6

But, I know it will takes us a really long time to get to 7,873.2, so what I will do is jump 3 sequences.

So if I multiply by 3 to get the next term, I'll multiply by 9 to get the next two terms because 3 * 3 is 9.

So to jump three times, I will multiply by 27 to get the next three terms because 3 * 3 * 3 is 27.

0.4 + 1.2 + 3.6 + ...

3.6 * 27 = 97.2

0.4 + 1.2 + 3.6 + ..., ..., 97.2, ...

97.2 * 27 = 2624.4

0.4 + 1.2 + 3.6 + ..., ..., 97.2, ..., ..., 2624.4, ...

Since we are getting close, I'm going to go back to multiply by 3.

2624.3 * 3 = 7873.2

0.4 + 1.2 + 3.6 + ..., ..., 97.2, ..., ..., 2624.4, 7873.2

Now that we have reached 7873.2, we will now count the terms (count the sets of three dots as terms too).

There are 10 terms in the geometric sequence.

The slope of a line passing through the point (5.-6) is 0.4.

Ella is 66 inches tall. Andy is 6 1/2 feet tall. Who is taller? By how much? (12 inches = 1 foot)

Answers

Answer:

Andy is taller by one foot or 12 inches

Step-by-step explanation:

Ella = 66 inches = 5'6"

Andy = 6 1/2 feet = 6'6"

Andy is taller by one foot or 12 inches

Andy is taller by one foot or 12 inches

Given:

Ella is 66 inches and Andy is 6 1/2 feet.

12 inches = 1 feet.

Convert inches in to feet.

12 inches = 1 feet.

1 inches = 1/12 = 0.083

66 inches = (0.083 * 66) = 5.5 feet.

Andy = 6 1/2 feet = 6.5 feet.

6.5 > 5.5 (6.5 is greater than 5.5).

Andy is taller by one feet or 12 inches

Therefore, Andy is taller by one feet.
