A biased dice is thrown.
nexus9112 [7]

Given:

A biased dice is thrown 300 times.

Table of probabilities of each score.

To find:

The expected number of times the score will be odd.

Solution:

Odd numbers on the dice are 1, 3, 5. The sum of their probability is

0.15+0.25+0.3=0.7

Even numbers on the dice are 2, 4, 6. The sum of their probability is

0.05+0.05+0.2=0.3

Now, the expected number of times the score will be odd is

\text{Expected odd number}=300\times \text{Probability of getting an odd number}

\text{Expected odd number}=300\times 0.7

\text{Expected odd number}=210

Therefore, the expected number of times the score will be odd is 210.

Ethan repairs household appliances like dishwashers and refrigerators. For each visit, he charges $25 plus $20 per hour of work.
dalvyx [7]

Answer:the independent variable is x, the number of hours of work.

The dependent variable is y, the total charge for x hours of work.

Step-by-step explanation:

A change in the value of the independent variable causes a corresponding change in the value of in dependent variable. Thus, the dependent variable is is output while the independent variable is the input

For each visit, he charges $25 plus $20 per hour of work. The linear expression that represents the total amount of money that Ethan earns per visit is y = 25 + 20x.

Since the total amount charged, y depends on the number of hours of work, x, it means that the dependent variable is y and the independent variable is x
