The graph to the right is the uniform probability density function for a friend who is x minutes late:

​(a) Find the probability that the friend is between 10 and 30 minutes late.

​(b) It is 10 A.M. and there is a 20​% probability the friend will arrive within how many​ minutes?

The step that indicates the addition property of equality while solving the equation -1 - 6x = x - 15 is : (b) -1 - 6x + 15 = x - 15 + 15.

The "addition-property" of equality states that if we add the same quantity to both sides of an equation, the equation remains true.

In the equation -1 - 6x = x - 15, we need to isolate the variable term 'x'.

To isolate variable "x",  we are adding 15 to both sides of the equation, which is the addition property of equality. This step simplifies the equation and isolate the variable "x" on one side.

So, we get,  -1 - 6x + 15 = x - 15 + 15,

Therefore, the correct step indicating the "addition-property" is (b).

A type of association that is seen between the age and height of the children include the following: C. positive linear association.

In Mathematics and Statistics, a positive correlation is used to described a scenario in which two variables move in the same direction and are in tandem.

This ultimately implies that, a positive correlation exist when two variables have a linear relationship or are in direct proportion. Therefore, when one variable increases, the other variable generally increases, as well.

By critically observing the scatter plot shown in the image attached above, we can reasonably infer and logically deduce that there is a positive correlation between the x-values (age) and y-values (height) because they both increase simultaneously.

The possible values of x, given the number of bets are $54,999, $14,999, and -$1.

The expected winnings would be -$0.97.

The possible values of the net winning would be the amount you win at net if you win first prize, second prize, or nothing.

The fraction in factored form is determined as  (x - 8)(x + 10) / (x - 10)(x + 8).

The quotient of the division is calculated as follows;

Now,

Here are four ordered pairs that relate the side length of a pentagon to the perimeter of the pentagon:

⇒ (1, 5) (2, 10) (3, 15) (4, 20)

Hence, In each pair, the first number represents the side length of the pentagon, and the second number represents the perimeter of the pentagon.

Since on average, 66% of the days in Seattle, Washington, are cloudy or rainy, a model that could be used to simulate this situation is an experimental probability model of about 2/3.

In this scenario and exercise, you are to required to describe a model that you could be used to simulate a situation in which 66% of the days in Seattle, Washington, are cloudy or rainy on an average.

In this context, we can reasonably infer and logically deduce that the most accurate and feasible model to use would be an experimental probability model of about 2/3;

66% = 66/100 = 33/50 ≈ 2/3.

In conclusion, you should select two (2) red marbles that each represent cloudy or rainy days and one (1) blue marble that represent non-cloudy or non-rainy days, and then pick one marble randomly.

Step-by-step explanation:

The volume of the composite figure is calculated as:

The volume of the composite figure can be calculated using:

Volume = volume of rectangular prism + 1/2(volume of cylinder)

Volume of rectangular prism = length * width * height

length = 15 cm

width =  2(6) = 12 cm

height = 10 cm

Volume of rectangular prism = 15 * 12 * 10 = 1,800 cm³

Volume of half Cylinder = 1/2(πr²h)

r = 6 cm

h = 10 cm

Volume of half Cylinder = 1/2(πr²h) = 1/2 * 3.14 * 6 * 10 = 94.20 cm³
