An experiment is pulling a ball from an urn that contains 3 blue balls and 5 red balls. a.) Find the probability of getting a red ball. b.) Find the probability of getting a blue ball. c.) Find the odds for getting a red ball. d.) Find the odds for getting a blue ball.

Answers

Answer:

Step-by-step explanation:

The urn contains 3blue balls 5 red balls

a) probability of getting a red ball

P=no of favourable of outcomes /total no outcomes

P(red ball) = 5/8

b) Probability of blue ball

P(blue ball) = 3/8

c) Odds getting a red ball

odds in favour of any object = m/n

m : event to occur

n : event will not occur

Odds(red ball) = 5/3

Odds(blue) = 3/5

Mr. and Mrs. Horner will be visiting the museum with their three children. Tickets cost $25 for adults and $15.50 for children. How much will it cost for the whole family to visit the museum?

Answers

Answer:

For the hole family it will cost 96.5$

Step-by-step explanation:

There are two adults, $25 each. 2×25=50

There are 3 children, 15.50 each. So you do 3×15.50= 46.5

To find the total cost add them both.

46.5+50= 96.5

Answer:

The total cost is $96.5

Roxanne wants to save up enough money so that she can buy a video game. The game costs $59. Roxanne has $22 saved from mowing the grass. In order to make more money, she plans to pressure wash her neighbors’ driveways.

An elementary n xn row replacement matrix is the same as the n x n identity matrix with__________ of the_____________replaced with some number k.This means this is the ___________and so its determinent is ___________.of its diagnol enteries. Thus, the determinant of an elementary row replacement matrix is______________.
1. Exactly one,atleast one
2. 1's or 0's
3. Identity matrix,invertible matrix, triangular matrix or zero matrix.
4. Product or sum
5. A number

Answers

Answer:

Step-by-step explanation:

Recall that an elementary matrix of a matrix operation is obtained by applying the matrix operation to the identity matrix. In this case, by replacement, it means changing the whole row of a matrix and replacing it with a the same row multiplied by a number k.

In this case, the solution is

What is the determinant of an elementary row replacement matrix?

An elementary n xn row replacement matrix is the same as the n x n identity matrix with Exactly one of the 1's replaced with some number k.This means this is the triangular matrix and so its determinent is product of its diagonal entries. Thus, the determinant of an elementary row replacement matrix is a number. Especifically, the number k we used to replace the one
