The probability of getting at least one tail when a coin is tossed 9 times is 0.8438. This can be calculated by adding the probability of getting 0 tails, 1 tail, 2 tails, 3 tails, 4 tails, 5 tails, 6 tails, 7 tails, 8 tails, and 9 tails together:

P(at least one tail) = P(0 tails) + P(1 tail) + P(2 tails) + P(3 tails) + P(4 tails) + P(5 tails) + P(6 tails) + P(7 tails) + P(8 tails) + P(9 tails)
= 0.0019 + 0.0156 + 0.0781 + 0.2051 + 0.3086 + 0.3086 + 0.2051 + 0.0781 + 0.0156 + 0.0019
= 0.8438

Therefore, the probability of getting at least one tail when a coin is tossed 9 times is 0.8438, which can be expressed as a decimal rounded to four decimal places.
The probability of getting at least one tail in a coin toss is 1 minus the probability of getting all heads.
The probability of getting a head in one toss is 0.5, so the probability of getting all heads in 9 tosses is 0.5^9 = 0.001953125.

So the probability of getting at least one tail is 1 - 0.001953125 = 0.998046875.
As a fraction, this can be written as 998046875/1000000000, which can be simplified to 511/512.
So the probability of getting at least one tail in 9 tosses is 0.9980 or 511/512.

4x7 = 28 divided by 5 which is 5.6

The LHS part is greater than the RHS part. So, The given expression is 10,000 less than 24,576 is greater than 1,000 less than 14,576.

Given data:

The given expression is 10,000 less than 24,576 is............ 1,000 less than 14,576.

The given expression is broken into two parts to get the result.

Consider it as the LHS part,

10,000 less than 24,576 can be expressed numerically as:

24,576 - 10,000 = 14,576

This is the LHS part,

Consider it as the RHS part,

1,000 less than 14,576 can be expressed numerically as:

14,576 - 1,000 = 13,576

This is the RHS part

The LHS part is greater than the RHS part. So, The given expression is 10,000 less than 24,576 is greater than 1,000 less than 14,576.

The set of numbers that could represent the sides of a triangle is

{ 11, 17, 26 }.

Option E is the correct answer.

We have,

To determine whether a set of three numbers can represent the sides of a triangle, we need to check if the sum of the two shorter sides is greater than the longest side.

This is known as the Triangle Inequality Theorem.

So,

{ 7, 10, 18 }:

7 + 10 = 17, which is less than 18.

Therefore, this set cannot represent the sides of a triangle.

{ 6, 19, 25 }:

6 + 19 = 25, which is equal to 25.

Therefore, this set cannot represent the sides of a triangle.

{ 11, 17, 26 }:

11 + 17 = 28, which is greater than 26. 17 + 26 = 43, which is greater than 11. Therefore, this set can represent the sides of a triangle.

{ 8, 16, 24 }:

8 + 16 = 24, which is equal to 24.

Therefore, this set cannot represent the sides of a triangle.

Thus,

The set of numbers that could represent the sides of a triangle is

The panicked reaction to the Ebola virus outbreak in 2014 can be attributed to several barriers to reasoning rationally.

These barriers include:

1. Availability Bias: People tend to overestimate the probability of an event occurring based on how easily they can recall similar instances. In the case of the Ebola virus, the extensive media coverage and graphic images of the outbreak may have made it seem more widespread and dangerous than it actually was.

2. Negativity Bias: People are more influenced by negative information and tend to focus on potential risks and threats. The fear of contracting a deadly virus like Ebola overshadowed the low probability of actually being infected.

3. Loss Aversion: People tend to have a stronger emotional response to potential losses than to gains. The fear of losing one's health and safety to a deadly virus can lead to exaggerated reactions and panic.

4. Overgeneralization: People often make generalizations based on limited or incomplete information. In the case of the Ebola outbreak, the limited number of cases in the United States led to the assumption that the virus was highly contagious and posed a significant risk to the general population.

It is important to note that these barriers to reasoning can hinder our ability to think rationally and make informed decisions. Understanding these biases can help us approach situations with a more balanced and evidence-based perspective.

Value of n(number of lawns) = 22

Step-by-step explanation:

She has already saved $85 which means the amount of money she needs left will be

=$415 - $85

= $330

Now n represents the number of lawns she needs to mow. She earns $15 per lawn, so she needs to multiply the cost of each lawn by the number of lawns (n) and equal it to the money she needs. This is how the equation will turn out.

15n = 330

To go further, divide both sides by 15 to get the number of lawns she has to mow.

\(\frac{15n}{15} =\frac{330}{15}\)

n = 22

∴ She needs to mow 22 lawns to get the amount of money she needs.

The approximate value of x in the equation 7x^3 + 9x^2 - 2 = 5 is x ≈ -1.153.

To find the approximate value of x in the equation 7x^3 + 9x^2 - 2 = 5, we need to solve for x.

Rearranging the equation, we have:

7x^3 + 9x^2 - 2 - 5 = 0

7x^3 + 9x^2 - 7 = 0

This equation is a cubic equation, which can be challenging to solve analytically. However, we can use numerical methods or software to approximate the value of x.

Using a numerical solver or a graphing calculator, we can find that there is a root near x ≈ -1.153.

It's important to note that this is an approximation, and the exact value of x may have more decimal places. Additionally, there could be other roots to the equation that are not visible in the given equation.

If a more precise value is required, you can use numerical methods like Newton's method or bisection method, or utilize software with higher precision calculations to find a more accurate approximation of x.
