Answer:

1. and 2.

Step-by-step explanation:

The correct answer is d) f^(-1)(x) = x/3, as it represents the Inverse relationship of y = 3x.

To find the inverse of a function, we need to switch the roles of x and y and solve for the new y.

The given function is y = 3x.

To find its inverse, let's swap x and y:

x = 3y

Now, solve this equation for y:

Dividing both sides of the equation by 3, we get:

x/3 = y

Therefore, the inverse function of y = 3x is f^(-1)(x) = x/3.

Among the given options:

a) f^(-1)(x) = 1/3x

b) f^(-1)(x) = 3x

c) f^(-1)(x) = 3/x

d) f^(-1)(x) = x/3

The correct answer is d) f^(-1)(x) = x/3, as it represents the inverse relationship of y = 3x.

Answer:

131.9 mph

Step-by-step explanation:

First, let's compute the circumference of the wheel, as this gives us the distance the car travels in one revolution of the wheel.

The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle. Given that the radius of the wheel is 20 inches, we can calculate the circumference as follows:

C = 2π * 20 inches = 40π inches

This is the distance the car travels in one revolution of the wheel.

Given that the wheel is making 346 revolutions per minute, the car is moving at a rate of 346 * 40π inches per minute. That's 13840π inches per minute.

Now let's convert this speed to miles per hour.

There are 12 inches in a foot and 5280 feet in a mile. So, there are 12 * 5280 = 63360 inches in a mile.

To convert inches per minute to miles per hour, we first convert inches to miles by dividing by 63360, then convert minutes to hours by multiplying by 60.

So the speed in miles per hour is (13840π / 63360) * 60 ≈ 131.9 mph.

Rounding to the nearest tenth, the linear speed of the car is approximately 131.9 mph.

Answer:

Step-by-step explanation:

85/1000 because we said that 1 meter = 1000 mililiters

Divide both sides by 5 and then you have 17/200

then divide both sides by 2 (to get it over 100) =

8.5/100

Hope that helps!!

You could also just do 85/1000 you would get the same answer!!

The required value of y for the unit circle is: 2/3

The circle is defined as the locus of a point whose distance from a fixed point is constant i.e center (h, k).

The equation of the circle is given by:

(x - h)² + (y - k)² = r²

where:

h, k is the coordinate of the center of the circle on coordinate plane.

r is the radius of the circle.

Here,

Equation of the unit circle is given as,

x² + y² = 1

Now substitute the given value in the equation,

5/9 + y² = 1

y² = 1 - 5/9

y² = 4/ 9

y = √(4/9)

y = 2/3

Thus, the required value of y for the unit circle is 2/3

Answer:

In the case presented, the range is the difference between the maximum value and the minimum value of the data. The range describes the breadth of the data and how much they vary from the minimum value to the maximum value. Therefore, the range indicates the dispersion of the data.

The statement indicates that the range is 5, which means that the most flights made by students is 5. Since the data has a narrow dispersion, we can conclude that most students have taken a similar number of flights, implying that most students have flown an amount close to the maximum number observed.

Therefore, the option that best describes the dispersion of the data is: "The data has a range of 5, which is a narrow dispersion. This means that most students have taken a similar number of flights."

Step-by-step explanation:

The independent variable, x in this scenario is; weeks.

The dependent variable, y in this scenario is; height.

It follows from the task content that the two variables which describe the growth model of the plants are; weeks and height.

Since, independent variable as the name implies is one whose values do not arrive from evaluation using other values, the independent variable in this scenario is; weeks.

However, by logic, the height of the plant is determined by the number of weeks and hence is dependent on the variable weeks. Therefore, the dependent variable is; height.

Ultimately, the independent and dependent variables are; weeks and height respectively.

Una caja de ahorros ofrece a sus clientes un interés simple del 8% anual por una imposición de 18.000 € durante 5 años. de los Interés es = 7,200 €

Interés = Principal × Tasa de interés × Tiempo

Dado que el principal es de 18.000 €, la tasa de interés es del 8% anual y el tiempo es de 5 años, podemos sustituir estos valores en la fórmula:

Interés = 18,000 € × 0.08 × 5

Interés = 7,200 €

Por lo tanto, el importe de los intereses generados en ese tiempo es de 7.200 €. Esto significa que al finalizar los 5 años, el cliente habrá obtenido 7.200 € adicionales como resultado de la imposición de 18.000 € con una tasa de interés del 8% anual.

To calculate the required sample size in Excel for estimating the true proportion of satisfied customers within a 3% margin of error with 99% confidence,

In Excel, you can use the NORM.S.INV function to find the critical value corresponding to the desired confidence level. In this case, we use 1 - (1-0.99)/2 to find the z-score for 99% confidence level.

We square this z-score and multiply it by (0.50.5)/(0.030.03), which represents the maximum variance under worst-case scenario and the desired margin of error. The CEILING function is used to round up the result to the nearest whole number since the sample size should be an integer.

you can use the formula =CEILING(MROUND((NORM.S.INV(1-(1-0.99)/2,0)^2)(0.50.5)/(0.03*0.03),1),1). The result will give you the minimum sample size needed for the desired confidence level and margin of error.

Answer:

y = \(\frac{36}{25}\)

Step-by-step explanation:

y ∝ \(\frac{1}{x^2}\)

=> y = \(\frac{k}{x^2}\) --------------(1)

Now, y = 4 and x = 3.

Putting in (1)

=> 4 = \(\frac{k}{9}\)

=> k = 4*9

=> k = 36

Now, y = ?, when x = 5

Putting in (1)

=> y = \(\frac{36}{5^2}\)

=> y = \(\frac{36}{25}\)

The answer is: a. Yes, the forecast fails the bias test.

To determine whether the forecast fails the bias test, we need to compare the Average Error (AE) with zero.

If the AE is significantly different from zero, it indicates the presence of bias in the forecast. If the AE is close to zero, it suggests that the forecast is unbiased.

In this case, the Average Error (AE) is -2.0, which means that, on average, the forecast is 2.0 units lower than the actual values. Since the AE is not zero, we can conclude that there is a bias in the forecast.

Therefore, the answer is:

Yes, it is necessary to assume that the populations from which you are sampling have equal population means and positive standard deviations when performing certain statistical tests, such as an Analysis of Variance (ANOVA) or a two-sample t-test.

These assumptions are important for the validity and accuracy of the test results.

Step-by-step explanation:

1. Equal population means: This assumption ensures that any observed differences between the sample means are due to random variation, not a systematic difference between the populations.

2. Positive standard deviations: This assumption ensures that the variability within each population is accurately represented and helps to determine the appropriate test statistic and critical value for the hypothesis test.

By making these assumptions, you can conduct statistical tests with greater confidence in the results, as they are based on sound principles of statistical theory.
