Answer:
14/9 or 1 5/9
Step-by-step explanation:
Answer:
1 \(\frac{5}{9}\)
Step-by-step explanation:
We require 2 equations with the repeating digit placed after the decimal point
let x = 1.555... (2) Multiply both sides by 10
10x = 15.555.... (2)
Subtract (1) from (2) thus eliminating the repeating digits
9x = 14 ( divide both sides by 9 )
x = \(\frac{14}{9}\) = 1 \(\frac{5}{9}\)

T/F: The proportion in the body of a normal distribution can never be less than 0.50.
This statement ''The proportion in the body of a normal distribution can never be less than 0.50.'' is false because the proportion in the body of a normal distribution can be less than 0.50, depending on the location of the mean and the spread of the distribution.
In fact, for a normal distribution with a mean of μ and standard deviation of σ, approximately 68% of the area under the curve falls within one standard deviation of the mean (i.e., between μ - σ and μ + σ), which means the proportion in the body of the distribution is about 0.68.
The remaining 32% is split evenly between the tails of the distribution, which means the proportion in each tail is about 0.16.
So, the proportion in the body of the distribution is greater than 0.50.

In the Bass forecasting model, the __________ measures the likelihood of adoption due to a potential adopter being influenced by someone who has already adopted the product.A.coefficient of innovationB.coefficient of imitationC.coefficient of regressionD.coefficient of the objective function
It is a useful tool for marketers and managers to plan product launches, allocate resources, and estimate potential market share.
The Bass forecasting model is a popular approach used in marketing and management to forecast the adoption of new products or services by consumers. It is based on the assumption that the adoption of a new product is driven by two factors: innovation and imitation.
The coefficient of innovation (p) represents the likelihood of adoption due to a potential adopter's intrinsic motivation or independent decision-making process to adopt the product, while the coefficient of imitation (q) represents the likelihood of adoption due to a potential adopter being influenced by someone who has already adopted the product.
The coefficient of imitation captures the network effect of adoption, where early adopters serve as opinion leaders and influence others to adopt the product. As more people adopt the product, the likelihood of adoption for potential adopters increases due to social influence and perceived social norms. This creates a positive feedback loop, leading to an S-shaped adoption curve over time.
The Bass model combines the coefficients of innovation and imitation to forecast the cumulative number of adopters over time. It is a useful tool for marketers and managers to plan product launches, allocate resources, and estimate potential market share.

1/5 de los animales en el zoológico son monos 5/7 de los monos son machos
¿Qué fracción de los animales en el zoológico son monos machos?
1/7 of the animals in the zoo are male monkeys.
What fraction of the animals in the zoo are male monkeys? Explain with workings.
To find the fraction of animals in the zoo that are male monkeys, we have to calculate the product of the fractions representing the proportion of monkeys and the proportion of male monkeys among them.
Given that 1/5 of the animals in the zoo are monkeys, we will then represent this as:
= 1/5
= 5/25.
And 5/7 of the monkeys are male which is written as 5/7.
To get fraction of male monkeys, we will multiply these two fractions:
= (5/25) * (5/7)
= 25/175
= 1/7.

a die is rolled twice and the sum of numbers appearing on the upper faces of them is observed to be 7. what is the probability that the number 2 has appeared atleast once? hint: use the concept of conditional probability)
The probability of getting at least one 2 given that the sum of the numbers is 7 is 2/6 or 1/3.
To find the probability that the number 2 has appeared at least once given that the sum of the numbers is 7, we need to use the concept of conditional probability.
Let's consider the possible outcomes when two dice are rolled. The total number of outcomes is 36, as each die has six possible outcomes.
Out of these 36 outcomes, there are six outcomes in which the sum of the numbers appearing on the upper faces is 7. These outcomes are (1,6), (2,5), (3,4), (4,3), (5,2), and (6,1).
Out of these six outcomes, there are two outcomes in which the number 2 appears at least once: (1,6) and (2,5).
We can use the formula for conditional probability to verify our answer:
P(2 appears at least once | sum is 7) = P(2 appears at least once and sum is 7) / P(sum is 7)
P(2 appears at least once and sum is 7) = 2/36 = 1/18 (as there are two outcomes with a sum of 7 that have a 2 in them)
P(sum is 7) = 6/36 = 1/6
So, P(2 appears at least once | sum is 7) = (1/18) / (1/6) = 1/3, which is consistent with our previous answer.

One study of mortality versus age used the following model to give the probability P of death from measles if contracted at age t years.
P = 1 / 1 + 77.39e^−0.08t
Here we assume that t is at least 2.
(a) What is the limiting value for this logistic function? Note: In other contexts, this would be known as the carrying capacity.
(b) Explain in practical terms the meaning of the limiting value you found in part (a).
The limiting value indicates that as age increases, the probability of death upon contracting measles at that age increases toward or %.
(c) At what age does the model predict that mortality due to measles is 50%? (That is a value of 0.5 for P. Round your answer to two decimal places.)
t =
(a) The limiting value for the logistic function is 1, meaning that as age increases, the probability of death upon contracting measles at that age approaches 100%.
(b) The limiting value of 1 indicates that as age increases, the risk of death from measles becomes almost certain.
(a) In the given model, the logistic function has a limiting value of 1. As age (t) increases, the probability of death from measles approaches 1, meaning that it becomes almost certain. This limiting value represents the maximum probability of death from measles that can be reached within the context of the model. It can be interpreted as the carrying capacity or upper bound for the probability of death from measles.
(b) In practical terms, the limiting value of 1 means that as individuals grow older, their vulnerability to death upon contracting measles increases significantly. The logistic model predicts that there is a point beyond which the risk of death becomes almost inevitable for individuals infected with measles. This underscores the importance of early vaccination and preventive measures, as they play a crucial role in reducing the risk of contracting measles at an early age when the probability of death is relatively lower.
(c) To find the age at which the model predicts a mortality rate of 50% (P = 0.5), we can set the given probability equation to 0.5 and solve for t. Substituting P = 0.5 into the equation, we get 0.5 = 1 / (1 + 77.39e^(-0.08t)). Solving this equation for t gives us t ≈ 8.66 years (rounded to two decimal places). Therefore, according to the model, the predicted age at which the mortality due to measles is 50% is approximately 8.66 years.
