So the probability of the cost being between $260 and $412 is 0.5953.

a. The probability that the cost will be $260 or less can be found by calculating the z-score and using a standard normal distribution table. The z-score is calculated as follows:

z = (x - μ)/σ

where x is the value we are interested in, μ is the mean, and σ is the standard deviation. In this case, x = 260, μ = 360, and σ = 88. So the z-score is:

z = (260 - 360)/88 = -1.14

Using a standard normal distribution table, we can find that the probability of the cost being $260 or less is 0.1271.

b. The probability that the cost will be more than $412 can be found by calculating the z-score and using a standard normal distribution table. The z-score is calculated as follows:

z = (x - μ)/σ

where x is the value we are interested in, μ is the mean, and σ is the standard deviation. In this case, x = 412, μ = 360, and σ = 88. So the z-score is:

z = (412 - 360)/88 = 0.59

Using a standard normal distribution table, we can find that the probability of the cost being more than $412 is 0.2776.

c. The probability that the cost will be between $260 and $412 can be found by subtracting the probability of the cost being $260 or less from the probability of the cost being $412 or less. Using the z-scores we calculated in parts a and b, we can find the probabilities from a standard normal distribution table:

P(x ≤ 260) = 0.1271
P(x ≤ 412) = 0.7224

P(260 < x < 412) = P(x ≤ 412) - P(x ≤ 260) = 0.7224 - 0.1271 = 0.5953

So the probability of the cost being between $260 and $412 is 0.5953.

Answer:

459 cases per 100,000 people.

Step-by-step explanation:

To calculate the prevalence of DMD, we need to know the number of people living with the condition at a specific point in time. We can estimate this number by multiplying the annual incidence rate by the average duration of the disease:

Prevalence = Annual incidence rate x Average duration of the disease

Annual incidence rate = 0.017% = 17 cases per 100,000 people per year

Average duration of the disease = 27 years

Therefore, the prevalence of DMD can be estimated as:

Prevalence = 17 cases per 100,000 people per year x 27 years = 459 cases per 100,000 people

So, approximately 459 people out of 100,000 are living with DMD. This can also be expressed as a percentage by multiplying the above value by 100, which gives:

Prevalence = 459 cases per 100,000 people x 100% = 0.459% of the population

Therefore, the prevalence of DMD is approximately 0.459% or 459 cases per 100,000 people.

The correct equivalent form of 8⁵/8² is Adam made an error in step 2. The denominator should be 1, not 8¹. Option B is correct.

In step 2, Adam used the property of exponents that states: [tex]a^{(m-n)}[/tex] = [tex]a^{m}[/tex] / [tex]a^{n}[/tex]. However, he made a mistake by writing 8¹in the denominator instead of 1.

The probability that the sample proportion will exceed 0.2983 is approximately 0.0708.

It is predicated on the likelihood that something will occur. The justification for probability serves as the basic foundation for theoretical probability. For instance, the theoretical chance of receiving a head while tossing a coin is half.

a) 0.28 percent of Canadians have green eyes. This ratio can be used to calculate the anticipated proportion of sample members who have green eyes:

Estimated number of green eyed individuals = Percentage of green eyed individuals * Sample size

Estimated population of those with green eyes: 600 divided by 0.28

168 persons with green eyes are anticipated.

As a result, we would anticipate that 168 members of the sample have green eyes.

b) The formula for calculating the sample proportion's standard deviation is:

Sample proportion's standard deviation is equal to sqrt[(p * (1-p)) / n].

where n is the sample size, and p is the percentage of people with green eyes (0.28). (600).

Sample proportion's standard deviation is equal to sqrt[(0.28 * (1-0.28)) / 600].

Sample proportion's standard deviation is 0.0258.

As a result, 0.0258 is the sample proportion's standard deviation.

c) We're looking for the likelihood that the sample proportion will be more than 0.2983. As the sample size is large enough to allow for the use of the normal approximation, we may use the conventional normal distribution to determine this probability.

Then, we must use the following formula to standardise the sample proportion:

z = [(P * (1 - P)] / sqrt[(p - P)]

where P is the population proportion (0.28), n is the sample size, and p is the sample proportion (0.2983) that we are interested in (600).

z = (0.2983 - 0.28) / sqrt[(0.28 * (1 - 0.28)) / 600]

z = 1.47

The chance of a standard normal variable reaching 1.47 can be calculated using a standard normal distribution table or calculator and is roughly 0.0708.

Thus, 0.0708 is about how likely it is that the sample proportion will be more than 0.2983.

Answer:

16-year-old horse is equivalent to a 48-year-old human. x = 48

Step-by-step explanation:

We can set up a proportion to solve this problem:

horse age / human age = k

where k is the constant of proportionality. We're told that a 5-year-old horse is equivalent to a 15-year-old human, so we can use this information to find k:

5 / 15 = k

k = 1/3

Now we can use this value of k to find the equivalent human age for a 16-year-old horse:

16 / x = 1/3

Multiplying both sides by x:

16 = x/3

Multiplying both sides by 3:

x = 48

So a 16-year-old horse is equivalent to a 48-year-old human.

Answer:

The fraction that is not equivalent to 25% is 2/5.

To see why, we can start by converting 25% to a fraction. Recall that "percent" means "per hundred," so 25% is equal to 25/100 or 1/4.

Now, we can check each of the answer choices to see if they are equivalent to 1/4:

1/4 is already in the form of 1/4, so it is equivalent to 25%.

5/20 can be simplified by dividing both the numerator and denominator by 5, which gives 1/4. So 5/20 is also equivalent to 25%.

25/100 is the same as 1/4 (we converted 25% to 1/4 earlier), so it is equivalent to 25%.

This leaves us with 2/5 as the answer choice that is not equivalent to 25%. We can see this by converting 2/5 to a percent:

2/5 = 0.4

0.4 x 100% = 40%

So 2/5 is equivalent to 40%, which is not the same as 25%.

Answer: [tex]2/5[/tex] second option

Step-by-step explanation: 1/4 is equal to 25% because if you multiply by 100 and divide by 4 that will equal 25. 5/20 simplified to 1/4 which we know is 25%, 25/100 also does too. Therefore, the answer is 2/5 because it simplifies to 40% which isn't 25%.

The predicted population of the school in 2012 is P = 1060 + 78.14(12) = 2002.68 students. We can round this up to 2003 students.

1. The population grew by _____students.

The population in 2001 was 1138 students, and in 2008, it had risen to 1691 students. Therefore, the population increased by 1691-1138 = 553 students.

2. The population took _____ years to grow from 1138 students to 1691 students.

From the year 2001 to the year 2008, the population increased from 1138 to 1691 students. The number of years it took for this growth is 2008-2001 = 7 years.

3. The average population growth per year is _____ students per year.

To obtain the average growth rate per year, divide the total growth in the population by the number of years between the starting year and the ending year. Therefore, the average population growth per year = (1691 - 1138) / 7 = 78.14 students per year.

4. The population in the year 2000 was _____ students.

Since the population was given for the year 2001, we'll have to work our way backward to find the population in the year 2000. It took 7 years for the population to increase from 1138 to 1691, so if we go back another year, we'll have to subtract the average yearly growth rate, which is 78.14 students. Therefore, the population in 2000 = 1138 - 78.14 = 1059.86 students, which we can round up to 1060 students.

5. An equation for the population P of the school t years after 2000 is P = _____.

We can use the formula for linear growth to determine the population of the school t years after 2000. The formula is P = P0 + rt, where P0 is the initial population (in the year 2000), r is the average annual growth rate, and t is the number of years. Therefore, the equation for the population P of the school t years after 2000 is P = 1060 + 78.14t.

6. The predicted population of the school in 2012 is _____ students.

To predict the population of the school in 2012 using the equation, we need to substitute t = 12 - 2000 = 12 into the equation we derived in part 5. Therefore, the predicted population of the school in 2012 is P = 1060 + 78.14(12) = 2002.68 students. We can round this up to 2003 students.

A geometric sequence is a sequence of numbers in which each term after the first is found by multiplying the previous term by a fixed number called the common ratio. The general formula for a geometric sequence is:

a, ar, ar², ar³, ...

where a is the first term and r is the common ratio.

To find the explicit formula for the sequence 7, 35, 175, we need to identify the pattern in the sequence.

Notice that each term is obtained by multiplying the previous term by 5. Specifically, the first term (7) is multiplied by 5 to get the second term (35), and the second term is multiplied by 5 to get the third term (175).

So, the sequence is a geometric sequence with a common ratio of 5.

The number of bacteria in the refrigerated food product at T = 3 is -100.5.

The number of bacteria in a refrigerated food product is given by the equation N(T) = 27T^2 - 148T + 100.5. This equation can be used to determine the number of bacteria in the product at any given time, T.

To find the number of bacteria at a specific time, simply plug in the value of T into the equation and solve for N(T). For example, if we want to find the number of bacteria at T = 3, we would plug in 3 for T and solve:

N(3) = 27(3)^2 - 148(3) + 100.5
N(3) = 27(9) - 444 + 100.5
N(3) = 243 - 444 + 100.5
N(3) = -100.5

Therefore, the number of bacteria in the refrigerated food product at T = 3 is -100.5. It is important to note that the number of bacteria cannot be negative, so this equation may not be valid for all values of T. It is important to check the validity of the equation for the specific time period in question.
