Step-by-step explanation:

Cora is flipping three coins at once. The probability that the number of landed coins showing "heads" is less than 3 is 0.875

Probability is a measure how likely an event occurs. Probability of an event A is calculated as:

P(A) = number of ways A can occur / total possible outcomes

Let A and B be independent events, then the followings hold:

P (A and B) = P (A∩B) = P(A) + P(B)

P (A or B) = P (A∪B) = P(A) · P(B)

P (not A) = P(Ā) = 1 - P(A)

In the given problem, H is an event where the number of landed coins showing heads.

The probability distribution for H is:

P(H = 0) = 0.125

P(H = 1) = 0.375

P(H = 2) = 0.375

P(H = 3) = 0.125

The probability of three coins show heads less than 3 is:

P(H < 3) = 1 - P(H=3)

             = 1 - 0.125 = 0.875

It can also be obtained using:

P(H<3) = P(H=0) + P(H=1) + P(H=2)

           = 0.125 + 0.375 + 0.375

           = 0.875

Hence, the probability of three coins show heads less than 3 is 0.875.

Complete question:

Cora is playing a game that involves flipping three coins at once. Let the random variable H be the number of coins that land showing "heads". Here is the probability distribution for H:

Answer:

Yes it is showing a function

Step-by-step explanation:

A within conditions pattern means the range of values is b. variability

The data or observations gathered inside a certain condition or context are included in the pattern of the condition. This could be done in accordance with a specific time period, group, experiment, or other set conditions. If the pattern seen under these circumstances displays a range of values, variability is present. In other words, the observations or data points are not constant or reliable. Instead, they show peaks and valleys or variations over the range of values.

This diversity may show up in several ways. For example, it might be seen, as a collection of unrelated data points lacking a discernible trend or pattern. It might also be seen as a large range of values, which would suggest that the data has a lot of dispersion or variance. However, it would not be seen as a within-conditions pattern indicating variability if data points or observations within the condition were reasonably stable, that is, they were closely grouped around a certain value or followed a steady trend.

Answer:

From 2010 to 2015 the population grew by 8778 (rounded answer 8800)

Step-by-step explanation:

*

68% of the population will have a height within the range of 69 inches to 75 inches. None of the provided options match this range.

In a normal distribution, approximately 68% of the values fall within one standard deviation of the mean.

Given:

mean height = 72 inches  

standard deviation = 3 inches,

We can determine the range within which 68% of the population's heights will fall.

To calculate this range, we subtract and add one standard deviation from the mean:

Lower bound: Mean - Standard Deviation

= 72 - 3

= 69 inches

Upper bound: Mean + Standard Deviation

= 72 + 3

= 75 inches

Therefore, 68% of the population will have a height within the range of 69 inches to 75 inches.

Answer: y = 5x + 26

Step-by-step explanation:

To find the equation of a line that is perpendicular to the given line y = -1/5x + 1 and passes through the point (-5, 1), we need to determine the slope of the perpendicular line. The given line has a slope of -1/5. Perpendicular lines have slopes that are negative reciprocals of each other. So, the slope of the perpendicular line will be the negative reciprocal of -1/5, which is 5/1 or simply 5. Now, we have the slope (m = 5) and a point (-5, 1) that the perpendicular line passes through.

We can use the point-slope form of a linear equation to find the equation of the line:

y - y1 = m(x - x1)

Substituting the values, we get:

y - 1 = 5(x - (-5))

Simplifying further:

y - 1 = 5(x + 5)

Expanding the brackets:

y - 1 = 5x + 25

Rearranging the equation to the slope-intercept form (y = mx + b):

y = 5x + 26

Therefore, the equation of the perpendicular line that passes through the point (-5, 1) is y = 5x + 26.

The respective values in gigabytes (G) using the 2 to the power notation based on the 1G = \(2^3^0\) relationship are 10M = 0.01G, 100M = 0.1G, 110M = 0.11G

To convert values using the 2 to the power notation, we can use the relationship that 1G equals 2 to the power of 30 (\(2^3^0\)).

Here's how to express 10M, 100M, and 110M using this notation:

1. 10M:

To convert 10M (10 million) to the 2 to the power notation, we need to express it in terms of G (gigabytes).

Since 1G is equal to \(2^3^0\), we can calculate the value of 10M as follows:

  10M = (10/1000)G = 0.01G

Therefore, 10M is equivalent to 0.01G.

2. 100M:

Similarly, to express 100M (100 million) in the 2 to the power notation:

  100M = (100/1000)G = 0.1G

Therefore, 100M is equivalent to 0.1G.

3. 110M:

For 110M (110 million) in the 2 to the power notation:

  110M = (110/1000)G = 0.11G

Therefore, 110M is equivalent to 0.11G.

(A) The degree of the polynomial is 2, and the leading coefficient is -3. The end behavior of the graph is that it approaches negative infinity as x approaches negative infinity, and it approaches positive infinity as x approaches positive infinity. (B) The zeros of the polynomial are x = 0 and x = 2. (C) The x-intercepts are x = 0 and x = 2, and the y-intercept is the point (0, 0). (D) The polynomial f(x) = -3x² + 6x is neither even nor odd.

(A) The given polynomial is f(x) = -3x² + 6x. The degree of a polynomial is determined by the highest power of x. In this case, the degree is 2, as the highest power of x is x². The leading coefficient is the coefficient of the term with the highest power of x. In this polynomial, the leading coefficient is -3.

Using the degree and leading coefficient, we can determine the end behavior of the graph. Since the degree is even (2), and the leading coefficient is negative (-3), the end behavior of the graph is as follows: as x approaches negative infinity, the graph approaches negative infinity, and as x approaches positive infinity, the graph approaches positive infinity.

(B) To find the zeros of the polynomial, we set f(x) equal to zero and solve for x:

-3x² + 6x = 0

Factor out common terms:

-3x(x - 2) = 0

Setting each factor equal to zero:

-3x = 0 or x - 2 = 0

Solving these equations, we find two zeros:

x = 0 and x = 2

Therefore, the zeros of the polynomial f(x) = -3x² + 6x are x = 0 and x = 2.

(C) To find the x-intercepts, we set f(x) equal to zero and solve for x, similar to finding the zeros. In this case, the x-intercepts are the same as the zeros we found in part (B): x = 0 and x = 2.

To find the y-intercept, we evaluate f(x) when x is equal to zero:

f(0) = -3(0)² + 6(0) = 0

Therefore, the y-intercept is the point (0, 0).

(D) To determine whether the polynomial is even, odd, or neither, we check if it satisfies the properties of even and odd functions. An even function satisfies f(x) = f(-x) for all x, and an odd function satisfies f(x) = -f(-x) for all x.

Let's check if the polynomial f(x) = -3x² + 6x satisfies these properties:

f(x) = -3x² + 6x

f(-x) = -3(-x)² + 6(-x) = -3x² - 6x

Since f(x) ≠ f(-x), the polynomial is neither even nor odd.

In summary:

(A) The degree of the polynomial is 2, and the leading coefficient is -3. The end behavior of the graph is that it approaches negative infinity as x approaches negative infinity, and it approaches positive infinity as x approaches positive infinity.

(B) The zeros of the polynomial are x = 0 and x = 2.

(C) The x-intercepts are x = 0 and x = 2, and the y-intercept is the point (0, 0).

(D) The polynomial f(x) = -3x² + 6x is neither even nor odd.

The probability that the sample proportion will be between 0.9115 and 0.946 from an infinite population with a known population proportion of 0.85 is required.

The given problem can be solved by using the Central Limit Theorem (CLT) for a sample proportion. Since the sample size is large (n = 51) and the population is infinite, we can assume that the distribution of the sample proportion is approximately normal.

The mean of the sample proportion is equal to the population proportion, which is 0.85. The standard deviation of the sample proportion is calculated using the formula:

σp = sqrt[p(1-p)/n] = sqrt[(0.85)(0.15)/51] = 0.0707

To find the probability that the sample proportion falls between 0.9115 and 0.946, we need to standardize the sample proportion using the formula:

z = (p - μp)/σp

Where μp is the mean of the sample proportion and σp is the standard deviation of the sample proportion.

z1 = (0.9115 - 0.85)/0.0707 = 0.88

z2 = (0.946 - 0.85)/0.0707 = 1.35

We can use a standard normal distribution table or a calculator to find the probability that the sample proportion falls between these two z-scores.

P(0.88 < z < 1.35) = P(z < 1.35) - P(z < 0.88) = 0.9115

Therefore, the probability that the sample proportion will be between 0.9115 and 0.946 is 0.9115

2nd and 4th option  is correct

What is standard deviation?

At first, it is important to know about variance.

Variance is the sum of the square of deviation from the mean.

On taking the square root of the variance, standard deviation is obtained.

Here, the cases are

1) Population standard deviation \((\sigma)\) is known

2) Population standard deviation \((\sigma)\) is unknown

3) Sample standard deviation (s) is known

4) Sample standard deviation (s) is unknown

Now,

Formula for z

z = \(\frac{x - \mu}{\sigma}\) , \(\mu\) is the population mean, \(\sigma\) is the population standard deviation

Formula for t

t = \(\frac{x - \mu}{s}\) ,  s is the sample standard deviation

So if  Population standard deviation \((\sigma)\) is known and Sample standard deviation (s) is unknown, z table is used

If Population standard deviation \((\sigma)\) is unknown and Sample standard deviation (s) is known, t table is used

(A)The probability that the fifth patient who comes to the hospital is the second patient with the virus is 0.0614.

(B)The average number of patients you will see without the virus before the second patient with the virus shows up is 16.1818.

(C)The probability that the tenth patient you see is the first one with the virus is 0.0385.

To answer these questions, we can use the geometric and negative binomial distributions. In the given scenario, the rate of infection for the new virus spreading through the town is 11%.

We will calculate the probabilities of specific events occurring, such as the fifth patient being the second patient with the virus, the average number of patients without the virus before the second patient with the virus shows up, and the probability of the tenth patient being the first one with the virus.

(A) The probability that the fifth patient who comes to the hospital is the second patient with the virus can be calculated using the geometric distribution. Since each patient has an independent probability of 11% to have the virus, the probability of the second patient having the virus is

0.11×0.89=0.0979, and the probability of the first four patients not having the virus is (0.89) ⁴ =0.6274.

Therefore, the probability is P=(0.89) ⁴×(0.11×0.89) =0.0614

(B) The average number of patients you will see without the virus before the second patient with the virus shows up can be calculated using the negative binomial distribution. The negative binomial distribution models the number of failures (patients without the virus) before a specified number of successes (patients with the virus).

In this case, we are interested in the second success, so the average number of patients without the virus before the second patient with the virus is E(X)= \(\frac{r(1-p)}{p}=\frac{2(1-0.11)}{0.11} =16.1818\), where r is the number of successes (2) and p is the probability of success (0.11).

(C) The probability that the tenth patient you see is the first one with the virus can also be calculated using the negative binomial distribution. In this case, we want the first success to occur on the tenth patient, so the probability is P=(1−p)⁹×p=0.0385, where p is the probability of success (0.11).

By using these distributions and the given probabilities, we can calculate the desired probabilities and average number of patients in the specified scenarios.
