*WORD PROBLEM* A jar contains dimes and quarters. Twenty percent of the coins in the jar are dimes. A number generator simulates

randomly selecting 10 coins from the jar. The number generator is used 12 times and the number of dimes in each trial is shown in the dot plot.
Which description is correct about the number generator is fair or not?




-The number generator is not fair. The dot plot shows a distribution that is skewed right.

-The number generator is fair. The dot plot shows a distribution that is skewed right.

-The number generator is fair. It shows that 20% of the coins selected are dimes most of the time.

-The number generator is not fair. In one of the experiments, no dimes are chosen.

Step-by-step explanation:

20% of the coins are dimes, and 10 coins are selected, so the expected number of dimes is 0.20 * 10 = 2.

So the number generator is fair. It shows that 20% of the coins selected are dimes most of the time.

In algebra, we often study relationships where a change to one variable causes change in another variable. Describe a situation
vampirchik [111]

Answer:

A familiar situation is: cost of books you pay for versus the quantity of books bought.

Cost of books ($) and quantity of books are directly proportionally related in the situation.

The graph will look like the graph in the attachment below.

A quantity (dependent variable) will change constantly in relation to another quantity (independent variable) if the relation is a proportional relationship.

A familiar situation for example can be the cost you pay for books will be directly proportional or dependent on the number of books you bought.

That is:

Number of books = independent variable

Cost ($) = dependent variable

A change in the number of books will cause a change in the cost you will pay for buying books.

This shows a direct proportional relationship between the two quantities.

On a straight line graph, the graph will be a proportional graph showing number of books on the x-axis against cost ($) you pay on the y-axis.

Therefore:

A familiar situation is: cost of books you pay for versus the quantity of books bought.

Cost of books ($) and quantity of books are directly proportionally related in the situation.

Step-by-step explanation:

Slope of line that passes through points (2,1) and (17,-17)
mojhsa [17]

Answer: y = -1,2x + 3.4

Step-by-step explanation:

y = ax + b

(2,1)      => 1    = 2a + b (1)

(17,-17) => -17 =17a + b (2)

Using caculator Mode => 5 =>1

We get : a=- 1.2 , b = 3.4

=> y = -1.2x + 3.4
