There are a total of 48 soccer games in the season.

Since there are 3 soccer games in a month, there will be 12 games in a season (3 games/month x 4 months). Since 8 games are played at night and assuming that all games are played either during the day or at night, we can calculate the number of games played during the day as:

Number of day games = Total number of games - Number of night games

= 12 games/month x 4 months - 8 night games/month x 4 months

= 48 games - 32 games

= 16 games

Therefore, the total number of games in the season is:

Total number of games = Number of day games + Number of night games

= 16 games + 32 games

= 48 games

So, there are 48 soccer games in the season.

Answer:

123.2 miles

Step-by-step explanation:

Given that One airplane is 78 miles due south of a control tower. Another airplane is 52 miles from the control tower at a heading of N 38 degrees E. To the nearest tenth of a mile, how far apart are the two airplanes?

The angle Ø = 90 + 52 = 142 degree

Or 180 - 28 = 142 degree

Using cosine formula

D^2 = 78^2 + 52^2 - 2(78)(52)Cos142

D^2 = 6084 + 2704 - 8112Cos142

D^2 = 8788 + 6392.34

D^2 = 15180.34

D = 123.2 miles

Therefore, the two planes are 123.2 miles apart.

To find the number of other flowers needed, she subtracts the number of roses from the total number of flowers. 36 minus 12 is 24. Thus, Diva needs 24 other flowers to finish the arrangement.

To solve the above word problem, let's follow the steps given below:

Step 1: Find the total number of flowers in the arrangement since the number of roses is known. Divide the number of roses by 1/3 to get the total number of flowers in the arrangement. 1/3 of the arrangement is roses. 12 roses represent 1/3 of the arrangement. 12 is equal to 1/3 of the total number of flowers in the arrangement.

Thus, let the total number of flowers in the arrangement be x.1/3 of the arrangement, which means:

(1/3) x = 12

Divide both sides of the equation by 1/3 to isolate x.

x = 12 ÷ 1/3x

= 12 × 3x

= 36

Step 2: Find the number of flowers that are not roses. Since Diva wants 1/3 of the arrangement to be roses, 2/3 of the arrangement should be other flowers.2/3 of the arrangement = 36 - 12

= 24 flowers.

Thus, Diva needs 24 other flowers to finish the arrangement. Diva wants to make a flower arrangement for her aunt's birthday. She has 12 roses, and she wants 1/3 of the arrangement to be roses. To find the number of other flowers needed, she must determine the total number of flowers needed for the entire arrangement.

She knows the 12 roses represent 1/3 of the arrangement. Thus, to find the total number of flowers in the arrangement, she must divide 12 by 1/3. This gives her x, which is equal to 36.

To find the number of other flowers needed, she subtracts the number of roses from the total number of flowers. 36 minus 12 is 24. Thus, Diva needs 24 other flowers to finish the arrangement.

Answer:

Step-by-step explanation:

To calculate the tax amount the girl should pay in a year, we need to determine the taxable income and then apply the corresponding tax rates.

The taxable income is calculated by subtracting the tax-free allowance from the girl's early income:

Taxable Income = Early Income - Tax-Free Allowance

Taxable Income = 150,000 - 100,000

Taxable Income = 50,000

Now, we can calculate the tax amount based on the given tax rates:

For the first 20,000 rupees, the tax rate is 12%:

Tax on First 20,000 = 20,000 * 0.12

Tax on First 20,000 = 2,400

For the remaining taxable income (30,000 rupees), the tax rate is 15%:

Tax on Remaining 30,000 = 30,000 * 0.15

Tax on Remaining 30,000 = 4,500

Finally, we add the two tax amounts to get the total tax she should pay in a year:

Total Tax = Tax on First 20,000 + Tax on Remaining 30,000

Total Tax = 2,400 + 4,500

Total Tax = 6,900

Therefore, the girl should pay 6,900 rupees in tax in a year.

The rate at which the volume of the snowball is changing at the instant the radius is 4 cm is -(448*pi)/15 cubic cm/minute.

The volume of a sphere is given by the formula V = 4/3 * pi * r³, where r is the radius. To find the rate at which the volume of the snowball is changing, we need to take the derivative of this formula with respect to time.

V = (4/3) * pi * (r)³

dV/dr = 4pir²

r = 21 - (21-14)/30*t (Where t = time in minutes)

dV/dt = dV/dr * dr/dt

=> dV/dt = 4pi(21 - (21-14)/30*t)² * -(21-14)/30

=> dV/dt = -4pi(21 - (21-14)/30*t)² / 30

dV/dt = -4pi(21 - (21-14)/30t)² / 30 = -4pi*(21-7)² / 30 = -4pi(14)² / 30 = -(448*pi)/15 cubic cm/minute.

Using the hypothesis test, the p-value is greater than the significance level, we fail to reject the null hypothesis. There is not enough evidence to suggest that a headed mannequin is more effective in selling clothing.

To perform a hypothesis test to determine if a headed mannequin is more effective in selling clothing, we can use a two-sample proportion test.

Let p1 be the proportion of women who would purchase the dress when presented on a mannequin with a head, and p2 be the proportion of women who would purchase the dress when presented on a headless mannequin.

The null hypothesis is that there is no difference between the two proportions, i.e. p1 = p2, and the alternative hypothesis is that p1 > p2 since we want to test if the headed mannequin is more effective.

We can use a significance level of 0.05. Using the given data, we calculate the test statistic as:

z = (p1 - p2) / √(p × (1-p) × (1/n1 + 1/n2))

where p = (x1 + x2) / (n1 + n2), x1 = 18, x2 = 12, n1 = 50, and n2 = 45.

The calculated z-value is approximately 1.02.

Using a standard normal distribution table, we find the p-value to be approximately 0.155.

The fact that she selected a green pair of swim goggles does not change the probability of selecting a green sand bucket. Each selection is independent of the other, and the probabilities of each event remain the same.

Given that executives for a car dealership are interested in the sales for the type of vehicle, suv or truck, and the type of power train, two-wheel drive (2wd), four-wheel drive (4wd), or all-wheel drive (awd).

The data from the sales of 165 vehicles is displayed in the two-way table. A vehicle is randomly selected.Let S be the event that the vehicle is an SUV and let D be the event that the vehicle has 4WD.To find the value of P(S and DC), we need to calculate the joint probability of the event S and the complement of D. Here, DC is the event that the vehicle doesn't have 4WD.

So, the probability of DC can be calculated as:P(DC) = 1 - P(D)P(D) = 4WD vehicles/165 vehicles= 58/165=0.35P(DC) = 1 - 0.35=0.65Now, to find the joint probability of S and DC, we can use the formula:P(S and DC) = P(S) * P(DC)So, the probability of an SUV with no 4WD is:P(S and DC) = P(S) * P(DC)= 0.23 * 0.65=0.1495≈0.15Hence, the value of P(S and DC) is approximately 0.15.

The z-score for P(? ≤ z ≤ ?) = 0.60 is approximately 0.25.

The z-score for P(z ≥ ?) = 0.30 is approximately -0.52.

How to find the Z score

P(Z ≤ z) = 0.60

We can use a standard normal distribution table or a calculator to find that the z-score corresponding to a cumulative probability of 0.60 is approximately 0.25.

Therefore, the z-score for P(? ≤ z ≤ ?) = 0.60 is approximately 0.25.

For the second question:

We want to find the z-score such that the area under the standard normal distribution curve to the right of z is 0.30. In other words:

P(Z ≥ z) = 0.30

Using a standard normal distribution table or calculator, we can find that the z-score corresponding to a cumulative probability of 0.30 is approximately -0.52 (since we want the area to the right of z, we take the negative of the z-score).

Therefore, the z-score for P(z ≥ ?) = 0.30 is approximately -0.52.
