The number of months, m, given the number of years, y is 12 years.

The Calendar in use today has 12 months every year. The length of the months is either 28, 29, 30, or 31 days. The 12 months of the Calender each have a length of 28 to 31 days. In a typical year, which has 365 days, each month has either 28, 30, or 31 days.

Months to Years Conversion. Divide the time by the conversion ratio to change the measurement from a month to a year. The months are equal to the years when split by 12.

12 months = 1 years

24 months = 2 years

36 months = 3 years

Answer: 4/9 es racional - cualquier fracción adecuada x/y es un número racional. Expresado como un decimal, esto es igual a 0.4 recurrente (es decir, 0.44444...)

Step-by-step explanation: ¡Espero que esto ayude!

El número 4/9 es un número racional. Es una razón, o fracción, formada por dos números enteros, 4 y 9.

The given equation is (1/2)a + (2/3) b = 50

and b = 30

Substituting the given value of b is above the equation we get

\(\large\displaystyle\text{$\begin{gathered}\sf \bf{\Rightarrow\left(\frac{1}{2}\right)a+\left(\frac{2}{3}\right)\times30=50 } \end{gathered}$}\)

\(\large\displaystyle\text{$\begin{gathered}\sf \bf{\Rightarrow \left(\frac{1}{2}\right)a+20=50 } \end{gathered}$}\)

\(\large\displaystyle\text{$\begin{gathered}\sf \bf{\Rightarrow\left(\frac{1}{2}\right)a=50-20=30 } \end{gathered}$}\)

\(\large\displaystyle\text{$\begin{gathered}\sf \bf{\Rightarrow a = 30 \times 2 = 60 } \end{gathered}$}\)

Therefore, a = 60 and b = 30 is a solution of the given equation.

Answer:

Answer

Step-by-step explanation:

The probability of the sum of the faces that the 2 dice are thrown simultaneously can be found by using the formula for the probability of independent events, which is P(A) * P(B).

The probability of the sum of the faces when 2 dice are thrown simultaneously depends on the specific sum you are looking for. You can use the formula P(A) * P(B) and the number of possible outcomes for each sum to find the probability.

First, let's determine the probability of each event. The probability of rolling a specific number on a single die is 1/6, since there are 6 possible outcomes. Therefore, the probability of rolling a specific number on both dice is (1/6) * (1/6) = 1/36.

Next, we need to determine the number of possible outcomes for the sum of the faces. There are 11 possible sums (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12), each with a different number of possible outcomes. For example, there is only one way to roll a 2 (1 + 1), but there are six ways to roll a 7 (1 + 6, 2 + 5, 3 + 4, 4 + 3, 5 + 2, 6 + 1).

Finally, we can use the formula to find the probability of each sum. For example, the probability of rolling a 7 is (6/36) = 1/6. The probability of rolling a 2 is (1/36).

The equation when solved for the variable 'c' is c = P-5/ 2

A subject of formula can be defined as the variable that is written or denoted in terms of other variables in an equation or expression.

It is known as the variables being worked out in an equation. It is allowed to stand on its own over the equality sign.

Given the equation;

P = 2c + 5

To make the variable 'c' the subject of formula, we take the following steps:

Take 5 over the equality sign

P - 5 = 2c

Now, divide both sides by the coefficient of 'c' which is 2

2c/ 2 = P - 5/ c

Find the quotient

c = P-5/ 2

Thus, the equation when solved for the variable 'c' is c = P-5/ 2

Answer: $120

Step-by-step explanation:

So you find 1/3 of 180, basically, you multiply them which is 60.

So if he has a third of the money, he has $60, but he needs 180. So we subtract $180 (how much money he needs) from $60 (the money he has). Which is 120 dollars, so the boy needs $120.

First, you need to graph all given points in the table, that way you will be able to determine the end behavior.

Remember, the end behavior of a function is the behavior of f(x) as x approaches to positive infinity and negative infinity.

So, based in the graph, we can say that as x approaches to positive infinity, f(x) approaches to negative infinity, and as x approaches to negative infinity, f(x) approaches to negative inifinity. In other words, in either case, f(x) always approaches to negative infinity.

Therefore, the right answer is the last choice.

Answer:

As x → ∞, f(x) → –∞, and as x → –∞, f(x) → –∞

The correct answers for this large university offering STEM are:

(A) To find the probability that a woman selected will not meet the age requirement, we add up the probabilities of her being 17, 18, or 19 years old:

(B) To find the probability that at least 30% of the women in the sample will not meet the age requirement, we can use the binomial distribution formula to find the probability that 0, 1, 2, ..., 30 women in the sample will not meet the age requirement, and then subtract this from 1 to get the complement:

Where:

(C) To compare the likelihood of a woman who does not meet the age requirement being selected in a stratified random sample versus a simple random sample, we need to find the probability of her being selected in each scenario.

In the stratified random sample, 30 women are selected from the group of women who do not meet the age requirement, and 70 are selected from the group who do meet the age requirement. So, the probability of a woman who does not meet the age requirement being selected in this scenario is:

In a simple random sample, a woman has a 0.223 probability of being selected if she does not meet the age requirement and a 0.777 probability of being selected if she does meet the age requirement. So, the probability of a woman who does not meet the age requirement being selected in this scenario is:

Since the probability of a woman being selected in the stratified random sample is greater than the probability of her being selected in a simple random sample, we can conclude that she is more likely to be selected in a stratified random sample.

Exponential smoothing is a popular forecasting technique used to predict future trends in time-series data. It works by assigning weights to historical data points, with more recent data points receiving higher weights. The level of smoothing is controlled by a smoothing parameter called alpha, which ranges between 0 and 1. As alpha increases, the influence of older data points decreases, and the model becomes more reactive to recent changes in the data.

When alpha is high, the exponential smoothing model group of answer choices tends to produce sluggish forecasts. This is because the model gives more weight to recent data points, which can cause it to overreact to short-term fluctuations in the data. As a result, the model may miss important trends or patterns in the data that would have been captured by a more balanced weighting scheme.

On the other hand, when alpha is low, the model tends to be more stable and less reactive to short-term changes in the data. This can be useful for predicting long-term trends or for smoothing out noisy data sets.

In summary, the choice of alpha in an exponential smoothing model depends on the characteristics of the data and the goals of the forecast. A high alpha value may be appropriate for short-term forecasting or for data sets with high volatility, while a low alpha value may be more suitable for long-term forecasting or for data sets with low volatility.
