Number of members came to help = 5.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Given,

15 members complete decoration in 12 hours,

After 4 hours left time = 8 hours

15 members will do the remaining work in 8 hours

Let x be the number of extra members join

15 + x members will do the remaining work in 6 hours

Work done = no. of members × time

Work is same

thus,

15 × 8 = 15+x × 6

120 = 90 + 6x

30 = 6x

x = 5

No. of extra members = 5

Hence, 5 members came to help.

Answer:

3.82 km

Step-by-step explanation:

Assuming that the change in elevation is linear, we can calculate the elevation change per km traveled.  The known values are the start (0km) and the sign (3km).  The elevation gain over that interval is (0.95-9.0)km = 0.5km.  That was for an distance interval of  3km, so we can write:

(0.5km elevation gain)/(3km distance)

We can use this as a rate change and and use it in a linear equation to predict the elevation as a function of distance.

Let y be the elevation and x the distance, both in km.

y = (0.183)(x)+b, where b is the elevation at the start of the trail.  We can find b by using this equation and entering one of the two data points.  Lets use the elevation of 0.95m at 3km distance:

y = (0.183)(x)+b

0.95 = (0.183)(3)+b

b = 0.4km

The full equation is :

y = (0.1833)X + 0.4

Enter 1.1 km for y and calculate x, the distance to reach 1.1 km altitude.

1.1 = (0.1833)X + 0.4

X = 3.82 km

The effective tax rate is 22%

What is effective tax rate?

 The percentage of income that an individual or business must pay or withhold as taxes is known as the effective tax rate. Individuals' average tax rate on earned income, such as wages, and unearned income, like stock dividends, is known as their effective tax rate. According to the progressive tax model, the tax rate rises as income rises, pushing individuals into a higher tax bracket. Each marginal tax rate only applies to taxable income earned within that bracket; any income earned outside of that range is taxed at the next highest tax rate. That means higher-income earners are taxed at a higher rate on all new income earned above the previous bracket.

Here the given table show us the effective rate for different tax brackets.

The given amount $63425 and its comes under the bracket $41176 - $89075. Then,

Effective tax rate = 22%

Answer:

15.18%

Step-by-step explanation:

$63,425 falls under the 22% marginal tax rate bracket.

Which means a full range of 10% and 12% will be filled.

$63,425 will consist of $10,275 the first bracket. The amount of money taxable in the 12% bracket we have to subtract $41,175 from $10,275

$41,175 - $10,275 = $30,900

For the 22% bracket, the taxable amount can be found by subtracting your taxable income by the maximum amount of the last bracket.

$63,425 - $41,175 = $22,250

We have three values for our taxable amount:

10% : $10,275

12% : $30,900

22% : $22,250

Now we multiply each of these by their respective tax rates.

Which gives us:

$1,027.5

$3,708.0

$4895.0

Now we add these up to find the total tax owed.

Which is $9,630.5

To find the effective tax rate we divide the total tax owed by taxable income and then multiply by 100.

$9,630.5/$63,425 = 0.1518407568 * 100 = 15.18407568% ≈ 15.18%

The scores that need to be examined in order to determine the median value of n = 24 are the 12th and 13th values.

In order to determine the median value of n = 24, you would need to examine the 12th and 13th scores. This is because the median value is the middle number of a sequence of values, so when there is an even number of values, the median is the average of the two numbers in the middle. So in the case of n = 24, there are two values in the middle, the 12th and 13th numbers. To find the median, you would need to add the two values together and divide the result by two. This will give you the median value of the sequence. If there were an odd number of values instead of an even number, then the median would be the middle number rather than the average of two numbers.

Answer:

There are 2 solutions to square root x = 9

They are 3, and -3

Step-by-step explanation:

The square root of x=9 has 2 solutions,

The square root means, for a given number, (in our case 9) what number times itself equals the given number,

Or, squaring (i.e multiplying with itself) what number would give the given number,

so, we have to find the solutions to \(\sqrt{9}\)

since we know that,

\((3)(3) = 9\\and,\\(-3)(-3) = 9\)

hence if we square either 3 or -3, we get 9

Hence the solutions are 3, and -3

\(~~~~~~150\times x\% = 35\\\\\implies 150 \times \dfrac{x}{100} = 35\\\\\implies \dfrac{3x}{2}=35\\\\\implies 3x = 35\cdot 2\\\\\implies 3x = 70\\\\\implies x = \dfrac{70}{3}\\\\\implies x =23.\overline{3}\\\\\text{So, 35 is}~ 23.\overline{3}\%~ \text{of} ~150.\)

2010

In the year 2010 the high school graduating class experience the greatest experience of change.

Finding the difference between two numbers is done using the subtraction technique. The size of a group of things decreases if any of the objects are removed.

For instance, at your birthday celebration, you purchased 9 cupcakes, of which your friends consumed 7. There are only 2 cupcakes remaining for you now. Nine minus seven equals two, which may be represented as the subtraction expression 9 - 7 = 2. (9 - 7) = 2 is the result of subtracting 7 from 9.

According to the question, the given values are :

There are 260 people in the graduating class in 2000, then it increased by 60.

5 years later the people class in the class was 320.

Then in the year 2010, it was 400.

So, the difference between 400 and 320 is 80.

Hence, this concludes that the greatest change will occur in 2010.

The triangular pyramid has a greater surface area than the square pyramid.

The surface area of a pyramid depends on the shape and dimensions of its base as well as its height and slant height. In this case, the square pyramid has a square base with sides of length 10 cm and four equilateral triangular faces with a height of 8.66 cm. The triangular pyramid has an equilateral triangular base with sides of length 10 cm and three identical equilateral triangular faces, each with a height of 8.66 cm.

To calculate the surface area of the square pyramid, we can first find the slant height of each triangular face using the Pythagorean theorem:

slant height = sqrt(10^2 + (8.66/2)^2) = 10.82 cm

Then, we can calculate the area of each triangular face as:

area = (1/2) * base * height = (1/2) * 10 cm * 8.66 cm = 43.3 cm^2

And finally, the total surface area of the pyramid is:

total surface area = area of base + 4 * area of triangular faces

= 10 cm * 10 cm + 4 * 43.3 cm^2

= 600.8 cm^2

To calculate the surface area of the triangular pyramid, we can use the formula:

surface area = area of base + 1/2 * perimeter * slant height

The area of the equilateral triangular base is:

area = (sqrt(3)/4) * base^2 = (sqrt(3)/4) * 10 cm^2 ≈ 21.65 cm^2

The perimeter of the base is simply 3 times the length of a side, or 30 cm. The slant height of each triangular face is 8.66 cm, so the surface area of the pyramid is:

surface area = 21.65 cm^2 + 1/2 * 30 cm * 8.66 cm

= 21.65 cm^2 + 130.0 cm^2

= 151.65 cm^2

Sure qhat is the question

To solve for the probability of a temperature of 98.5 or lower, we need to find the z-score for 98.5 using the formula z = (x - mu) / sigma, where x is the temperature, mu is the mean, and sigma is the standard deviation.

z = (98.5 - 98.6) / 0.8 = -0.125

Using a standard normal distribution table or calculator, we can find the probability of z being less than or equal to -0.125, which is 0.4502. Therefore, the probability of a temperature of 98.5 or lower for a randomly selected healthy person is 0.4502.

No, a temperature of 98.5 is not an unlikely occurrence for a single individual, given that the distribution of human body temperatures is approximately normal with a mean of 98.6 and a standard deviation of 0.8. The probability of a temperature of 98.5 or lower is about 0.45, which means that there is a reasonable chance that a healthy person could have this temperature.

Thus, to solve for the probability of an average temperature of 3.5 or lower for 135 healthy people, we need to use the central limit theorem, which states that the distribution of sample means will be approximately normal with a mean of the population mean and a standard deviation of the population standard deviation divided by the square root of the sample size.

The standard error of the mean (SEM) is calculated as SEM = sigma/sqrt (n), where sigma is the population standard deviation and n is the sample size.

SEM = 0.8 / sqrt(135) = 0.068

The z-score for an average temperature of 3.5 is calculated as z = (3.5 - 98.6) / 0.068 = -1375.74

Using a standard normal distribution table or calculator, we can find the probability of z being less than or equal to -1375.74, which is essentially 0. Therefore, the probability of an average temperature of 3.5 or lower for 135 healthy people is almost 0.
To answer your questions, we will use the normal distribution properties of human body temperatures.

(1) To find the probability that the temperature for a randomly selected healthy person is 98.5 or lower, we need to calculate the z-score:

z = (X - μ) / σ
z = (98.5 - 98.6) / 0.8
z = -0.1 / 0.8
z = -0.125

Now, we can look up the probability in a standard normal distribution table or use a calculator to find the area to the left of z = -0.125. The probability is approximately 0.4505 (rounded to four decimal places).

(2) A temperature of 98.5 is not an unlikely occurrence for a single individual, given that the true average temperature of healthy people is 98.6. The probability of having a temperature of 98.5 or lower is 0.4505, which is not very small, so this is not an unlikely event.

(3) To find the probability that the average temperature for a sample of 135 healthy people is 98.5 or lower, we first need to find the standard error (SE) of the sample mean:

SE = σ / √n
SE = 0.8 / √135
SE ≈ 0.0688

Next, we calculate the z-score for the sample mean:

z = (X - μ) / SE
z = (98.5 - 98.6) / 0.0688
z ≈ -1.451

Now, we look up the probability in a standard normal distribution table or use a calculator to find the area to the left of z = -1.451. The probability is approximately 0.0735 (rounded to four decimal places).
