Answer:
True.
Step-by-step explanation:
A probability distribution is a listing of all the outcomes of an experiment and the probability associated with each outcome. Probability distribution is associated with the following characteristics or properties;
1. The outcomes are mutually exclusive.
2. The list of outcomes is exhaustive, which simply means that the sum of all probabilities of the outcomes must equal one (1).
3. The probability for a particular value or outcome must be between 0 and 1.
Since a probability distribution gives the likelihood of an outcome or event, a single random variable is divided into two main categories, namely;
I. Probability density functions for continuous variables.
II. Discrete probability distributions for discrete variables.
For example, when a coin is tossed, you can only have a head or tail (H or T).
Also, when you throw a die, the only possible outcome is 1/6 and the total probability for it all must equal to one (1).
3 1/2 cm or 3.5 cm. Because you should divide 280 by 80 which equals 3.5. turn 3.5 to centimeters. Thats your answer.
Answer:
Sarah can have the plumber work on her faucet for six (6) hours maximum
Step-by-step explanation:
Hi
As Sarah has only $234.50 in her savings and the plumber charges $50 just to come to her home, so left-over $184.50 of her saving for pay work hours.
Then as the plumber charges $30.75 per hour we have that 
is the maximum amount of hours that Sarah can have the plumber work on her faucet.
Answer: B
Step-by-step explanation:
Answer:
7 Rows with one row having 6 Chairs. The other 6 Rows will have 8 chairs each.
6x8 = 48 chairs + 1x6 = 54 chairs.
Step-by-step explanation:
1 Row = 8 Chairs [1Row/8Chairs]
(1Row/8Chairs)*(54Chairs) = (54/8) Rows = 6.75 Rows
The manager needs 7 rows, one row will have only 6 chairs [(0.75 Rows)*(8Chairs/1Row) = 6 Chairs
