It is spun twice.
What is the probability of getting green both times?

Answer:

y = -2x + 9

General Formulas and Concepts:

The median number of free throws made is 5.5.

To find the median, we first need to arrange the number of free throws made in order from lowest to highest:

3, 4, 5, 5, 5, 6, 6, 7, 8, 9

There are 10 numbers in the list, so the median is the average of the fifth and sixth numbers.

(5 + 6) ÷ 2 = 5.5

Therefore, the median number of free throws made is 5.5.

The median is a measure of central tendency that is used to describe the middle value or values of a dataset. It is especially useful when dealing with datasets that have extreme values or outliers, which can skew the mean.

The median is found by ordering the values in the dataset from lowest to highest and then finding the middle value(s). If there are an even number of values, the median is the average of the two middle values.

In this case, there were an even number of values, so we took the average of the fifth and sixth numbers to find the median.

Statistics is a set of mathematical procedures used to collect, analyze, and interpret data.

Generally, it involves collecting data from a sample population, organizing the data into a meaningful manner, and then applying statistical methods to draw conclusions from the data. Statistical methods include descriptive statistics, which summarize the data, and inferential statistics, which use the data to make predictions about a larger population.

Descriptive statistics uses various measures to summarize a population, such as the mean, median, and mode. The mean is the average of all the values in a population and is calculated by adding up all the values and dividing by the number of values. The median is the middle value when all the values in a population are arranged from smallest to largest. The mode is the most frequently occurring value in a population.

Inferential statistics uses the data from a sample population to make predictions about a larger population. For example, a researcher might use a statistical test to determine if a certain treatment is effective. The researcher would collect data from a sample of the population, then use a statistical test to determine if the treatment had an effect on the sample population. If the test is statistically significant, then the researcher can conclude that the treatment is likely to have an effect on the larger population.

The height of peak is around 2346.9 feet according to stated angles and distance.

The flat base, vertical height of the peak and angle of elevation form a right angled triangle. Hence, the trigonometric relation that will form is -

tan theta = perpendicular/base.

Let the distance between peak and hiker be x from the point of 500 feet

The height based on the first elevation angles of 30° -

tan 30° = perpendicular/(500 + x)

Perpendicular = 0.577 × (500 + x)

Performing multiplication

Perpendicular = 288.67 + 0.577x

The height based on the second elevation angles of 35° -

tan 35° = perpendicular/x

Perpendicular = 0.7 × x

Performing multiplication

Perpendicular = 0.7x

Now equating the height of peak -

288.67 + 0.577x = 0.7x

0.7x - 0.577x = 288.67

0.123x = 288.67

x = 288.67/0.123

x = 2346.9 feet

Hence, the height of peak is 2346.9 feet.

Straight-line graphs are commonly referred to as "linear graphs" or "linear equations."

We have,

A straight line graph, often referred to as a linear graph or linear equation, represents a relationship between two variables that can be expressed by a linear equation in the form y = mx + b.

In this equation, 'x' and 'y' are the variables, 'm' is the slope of the line, and 'b' is the y-intercept (the point where the line crosses the y-axis).

The slope 'm' determines the steepness or incline of the line.

A positive slope indicates the line rises as 'x' increases, while a negative slope indicates the line descends as 'x' increases.

The y-intercept 'b' represents the value of 'y' when 'x' is zero, determining where the line crosses the y-axis.

Step-by-step explanation:

The total number of ways a chairperson, a secretary, and a treasurer can be selected is 990 ways.

What is meant by selection?

A selection principle is a rule in mathematics that states it is possible to choose elements from predetermined sequences of sets in order to generate mathematically important objects. Studying these principles and how they relate to other mathematical features is called the theory of selection principles.

It is said that there are a total of 11 members on a board of directors.

We are asked to find the number of ways a chairperson, a secretary and a treasurer can be selected.

Number of places to be selected for = 3

Number of members = 11

We are assuming the order of selection in the order of importance of the designation.

So first chairperson, second secretary and third treasurer will be selected.

Then the number of ways the chairperson can be selected = 11 ways

When the chairperson is selected, 1 person reduces.

Then the number of ways the secretary is selected = 10

Now the remaining people are 9.

Then the number of ways the treasurer is selected = 9

Therefore the total number of ways a chairperson, a secretary, and a treasurer can be selected is = 11*10*9 = 990 ways.

Answer:

(a) 0.2824

(b) 0.0002441

Step-by-step explanation:

Assuming that the population is large enough to behave as a binomial distribution (between whites and non-whites), the probability of 12 out of 12 juros being white is:

\(P(w=12) = p(w)^{12}\)

Where p(w) is the proportion of the population that is white:

(a) for p = 0.90

\(P(w=12) = 0.90^{12}\\P(w=12) =0.2824\)

The probability is 0.2824.

(b) for p = 0.50

\(P(w=12) = 0.50^{12}\\P(w=12) =0.0002441\)

The probability is 0.0002441.

As per the combination method, the number of tickets that we put in that are marked "outer" is 3 (option d).

In this case, we want to choose the number of tickets marked "outer." Let's call this number k. We know that we already put one ticket marked "inner" in the box, so the total number of tickets in the box is 2. Therefore, n = 2.

Now we need to determine k. We want to know how many tickets we need to put in that are marked "outer." We can represent this as a. So we have:

ᵃC₁ = a! / ((1!)(a-1)!) = a

We want to find the value of a that satisfies the condition that the probability of choosing an "inner" ticket is 1/3 and the probability of choosing an "outer" ticket is 3/2.

Since we already put in 1 ticket marked "inner," the probability of choosing an "inner" ticket is 1/2, which means the probability of choosing an "outer" ticket is also 1/2.

We know that the probability of choosing an "outer" ticket is 3/2, so we can set up the following equation:

ᵃC₁ / 2 = 3/2

Solving for a, we get:

a = 3

In conclusion, the answer is (d) 3.

The amount of work required to fill a cylindrical tank with a cross-sectional area following the graph of y is dependent on the size of the tank and the amount of water needed to fill it.

It depends on the size of the tank and how much water is needed to fill it. If we assume the tank is cylindrical and the cross-sectional area follows the graph of y, then the volume of the tank can be calculated using the formula V = πr2h, where r is the radius and h is the height of the tank. If we assume the tank needs to be filled with 1 cubic meter of water, then the total work required would be 9 cubic meters.

The probability that all five balls drawn out of the box at random are white is approximately 0.001082.

To find the probability that all five balls drawn out of the box at random are white, follow these steps:

1. Calculate the total number of balls in the box: 5 white balls + 6 black balls = 11 balls
2. Determine the probability of drawing the first white ball: 5 white balls / 11 total balls = 5/11
3. After drawing the first white ball, there are now 4 white balls and 10 total balls remaining. Determine the probability of drawing the second white ball: 4 white balls / 10 total balls = 4/10
4. After drawing the second white ball, there are now 3 white balls and 9 total balls remaining. Determine the probability of drawing the third white ball: 3 white balls / 9 total balls = 1/3
5. After drawing the third white ball, there are now 2 white balls and 8 total balls remaining. Determine the probability of drawing the fourth white ball: 2 white balls / 8 total balls = 1/4
6. After drawing the fourth white ball, there is now 1 white ball and 7 total balls remaining. Determine the probability of drawing the fifth white ball: 1 white ball / 7 total balls = 1/7

To find the probability of all five events occurring, multiply the probabilities together: (5/11) * (4/10) * (1/3) * (1/4) * (1/7) = 0.00108225108

So, the probability that all five balls drawn out of the box at random are white is approximately 0.001082, or 0.1082%.
