Step-by-step explanation:

We may build up a proportion and solve for the scale model radius of Neptune using the ratio between the radii of the two planets and the known scale model radius of the Earth. The scale model of Neptune that is produced has a radius of around 9.7 cm.

We may take advantage of the fact that the ratio between the two planets' radii and the ratio between their respective scale model radii is the same. Let's name the Neptune scale model radius "r" Then, we may set up the ratio shown below:

Neptune's radius is equal to the product of Earth's radius and its scale model.

With the provided values, we may simplify and obtain:

24620 km / 6370 km equals 2.5 cm / r

We obtain the following when solving for "r":

r = (24620 km * 2.5 cm) / (6370 km)

r ≈ 9.7 cm

Therefore, a scale model of Neptune would have to be drawn with a radius of approximately 9.7 cm.

Step-by-step explanati

Answer:

The correct answer is (b): Since F test statistic 1.10 < F critical value 2.28, do not reject the null.

To test the hypothesis, we need to perform an F-test for two population variances. The test statistic is given by:

F = (stdev1^2 / stdev2^2)

Under the null hypothesis, this follows an F-distribution with degrees of freedom (n1-1) and (n2-1).

We can calculate the F statistic as follows:

F = (1450/1320) = 1.098

Using a significance level of 0.05, the critical F value with (12,20) degrees of freedom is 2.28.

Since our calculated F value (1.098) is less than the critical F value (2.28), we fail to reject the null hypothesis.

Therefore, the correct answer is (b): Since F test statistic 1.10 < F critical value 2.28, do not reject the null.

The correct answer is (b) Since F test statistic 1.10 < F critical value 2.28, do not reject the null.

To test the hypothesis, we use the F-test. The F test statistic is calculated as follows:
F = (stdev1^2 / stdev2^2). Under the null hypothesis, this statistic follows an F-distribution with degrees of freedom (df1 = n1 - 1) and (df2 = n2 - 1). Using a significance level of 0.05, the critical F-value with df1 = 12 and df2 = 20 is 2.28.

Calculating the F statistic with the given sample information, we get:
F = (1450 / 1320) = 1.10
Since 1.10 < 2.28, we fail to reject the null hypothesis.
Therefore, the correct answer is (b) Since F test statistic 1.10 < F critical value 2.28, do not reject the null.

28° because this is an isosceles triangle, and isosceles triangles have congruent base angles.

Answer:

A or 28

Step-by-step explanation:

Cause if both of the sides is 6, than that means that its equal. So 28 on one side and 28 on the other.

Step-by-step explanation:

I am not sure I can read the original expression right, the picture is too blurry for the small digits.

is it 3^(5/5) ?

or rather 3^(5/6) ?

in any case, you should know that a number written like this always has the structure

a^(b/c)

so,

a = 3

b = 5 (or whatever is the numerator or top of the fraction)

c = 5 (or whatever is the denominator or bottom of the fraction).

the denominator of a fraction in an exponent gives us the grade of root to be taken.

the numerator gives us the power of the base number.

and if the exponent is negative it would mean that the whole thing is a 1/... fraction.

The correct statement about coping strategies is: An effective coping strategy is any strategy that reduces stress.

The correct option is B .

Coping strategies are techniques or actions that individuals use to manage or deal with stressful situations. Different strategies work for different people, so there isn't a one-size-fits-all approach. However, an effective coping strategy is any strategy that successfully reduces or manages stress.

Some examples of effective coping strategies include deep breathing exercises, engaging in physical activity or exercise, seeking support from friends or family, practicing mindfulness or meditation, and engaging in hobbies or activities that bring joy and relaxation.

It's important to note that while ineffective coping strategies may not completely eliminate stress, they can still provide temporary relief or distraction. However, it is generally recommended to focus on developing and using effective coping strategies that can effectively reduce stress and promote overall well-being.

The number of seats in the front row of the theater is a = [2y/(n(n-1)) - x/(n-1)]/2

Let's call the number of seats in the first row "a". We can use the information given in the problem to set up an equation in terms of "n", "d", "x", and "y"

y = a + (a + d) + (a + 2d) + ... + (a + (n-1)d) (1)

We can simplify this equation by using the formula for the sum of an arithmetic series

y = [n/2][2a + (n-1)d] (2)

We can solve this equation for "a" in terms of "n", "d", and "x"

2a = (2y/n) - (n-1)d - 2xd

a = [(2y/n) - (n-1)d - 2xd]/2

Since we know that the number of seats in the last row is "x", we can substitute that into the equation

x = a + (n-1)d

x = [(2y/n) - (n-1)d - 2xd]/2 + (n-1)d

Simplifying this equation gives us

2x = (2y/n) + (n-1)d

2d = (2x - (2y/n))/(n-1)

Now we can substitute this value of "d" into the equation we found for "a"

a = [(2y/n) - (n-1)d - 2xd]/2

a = [(2y/n) - x - (2x - (2y/n))/(n-1)]/2

a = [2y/(n(n-1)) - x/(n-1)]/2

-6 < 3r < 9

divding each term by 3,

-6/3 < r < 9/3

-2 < r < 3

or, -2 < r < 3

this corresponds to

The fourth choice (since there is no equality sign)

The dividend in 2018 was $2.95, and it is expected to grow at a rate of 7.4% for the next five years and 2.6% thereafter. With an equity cost of capital of 8.6%, the value per share at the end of 2018 can be calculated.

To calculate the value per share at the end of 2018, we need to discount the expected future dividends using the dividend-discount model. The model assumes that the value of a stock is equal to the present value of all its expected future dividends.

First, we need to calculate the dividends for each year from 2019 to 2023. We start with the dividend in 2018, which was $2.95. We then increase it by 7.4% each year for the next five years:

Dividend in 2019 = $2.95 * (1 + 7.4%) = $3.17

Dividend in 2020 = $3.17 * (1 + 7.4%) = $3.40

Dividend in 2021 = $3.40 * (1 + 7.4%) = $3.65

Dividend in 2022 = $3.65 * (1 + 7.4%) = $3.92

Dividend in 2023 = $3.92 * (1 + 7.4%) = $4.22

After 2023, the dividend is expected to grow at a rate of 2.6% per year. To find the value per share at the end of 2018, we discount the future dividends to their present value using the equity cost of capital of 8.6%.

The present value of the dividends can be calculated as follows:

PV = (D1 / (1 + r)) + (D2 / (1 + r)^2) + ... + (Dn / (1 + r)^n)

where PV is the present value, D1 to Dn are the dividends for each year, r is the equity cost of capital, and n is the number of years.

In this case, n = 5 because we are discounting the dividends for the next five years. Let's calculate the present value:

PV = ($3.17 / (1 + 8.6%)) + ($3.40 / (1 + 8.6%)^2) + ($3.65 / (1 + 8.6%)^3) + ($3.92 / (1 + 8.6%)^4) + ($4.22 / (1 + 8.6%)^5)

PV = $3.17 / 1.086 + $3.40 / 1.086^2 + $3.65 / 1.086^3 + $3.92 / 1.086^4 + $4.22 / 1.086^5

PV ≈ $2.91 + $3.07 + $3.24 + $3.41 + $3.59

PV ≈ $16.22

Therefore, the estimated value per share of Procter and Gamble at the end of 2018 using the dividend-discount model is approximately $16.22.

The value of (x,y) on the given points of the function will be (-2,10),(-1,7),(0,4),(1,1), and (2,-2).

A certain kind of relationship called a function binds inputs to essentially one output.

In other words, the function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.

As per the given function,

f(x) = 3(2 – x) –2

Put x = -2
