The mean of a data set can be greater than any of the data sets is True.

The average is basically a model of the dataset. The most frequently occurring value. However, the mean value is often not one of the actual values observed in the dataset. The median can be larger or smaller than the mean of the distribution. So the given statement is wrong.

The mean is affected by outliers that do not influence the mean. Therefore, when the average distribution of data is skewed to the left, the mean is often less than the median. When the distribution is skewed to the right, the mean is often greater than the median. No matter what value we add to the set, the mean, median, and mode will shift by that amount but the range and the IQR will remain the same. The same will be true if we subtract an amount from every data point in the set.

Answer:

d=4

Step-by-step explanation:

First, you have to move the 7 to the left and only keep the d on the right.

41+7=12d (Remember to change the sign)

48=12d (Add the like terms)

Then you have to find the HCF (Highest Common Factor), which is 12.

At last divide both sides by the HCF (12)

So, d=4

Using a paired t-test with a significance level of 5%, we can test the hypothesis that mood rating improved after being exposed to classical music.

The null hypothesis is that there is no difference in mood rating before and after being exposed to music.

Calculating the t-statistic with 3 degrees of freedom and a difference in means of -1.08, we get a t-value of -3.18.

The critical t-value at the 5% level of significance is ±3.18. Since the calculated t-value falls outside of this range, we reject the null hypothesis. Therefore, we can conclude that there is evidence to suggest that mood rating improved after being exposed to classical music for the four participants in the sample.

The expected change in m if GDP increases by 4% is approximately -2%.

The given equation is a logarithmic regression model that relates the quantity of (real) money (m) to the value of (real) gross domestic product (GDP) and the nominal interest rate (R). The equation is expressed as ln(m) = β0 + β1ln(GDP) + β2R, where β1 = 2.78 and β2 = -0.09.

To determine the expected change in m when GDP increases by 4%, we need to substitute the new GDP value into the equation and calculate the resulting change in m.

Let's consider the scenario where the initial GDP increases by 4%. We can calculate the change in m by plugging the new GDP value into the equation:

ln(m') = β0 + β1ln(GDP') + β2R,

where m' represents the new quantity of money and GDP' is the new GDP value.

Since we are interested in the change in m, we subtract the initial equation from the new equation:

ln(m') - ln(m) = β0 + β1ln(GDP') + β2R - β0 - β1ln(GDP) - β2R,

Simplifying the equation:

ln(m'/m) = β1(ln(GDP') - ln(GDP)),

Using the property of logarithms, ln(a) - ln(b) = ln(a/b):

ln(m'/m) = β1ln(GDP'/GDP).

Now, we know that GDP increased by 4%, so GDP'/GDP = 1 + 0.04 = 1.04. Substituting this value into the equation:

ln(m'/m) = β1ln(1.04),

Since ln(1.04) is a constant, we can multiply both sides by β1:

ln(m'/m) * β1 = \(β1^2\) * ln(1.04),

ln(m'/m) * β1 = 2.78 * ln(1.04),

Finally, we can solve for ln(m'/m) by dividing both sides by β1:

ln(m'/m) = 2.78 * ln(1.04) / β1.

Using the given values, β1 = 2.78 and β2 = -0.09, we can calculate the approximate change in m by exponentiating both sides:

m'/m = \(e^(^2^.^7^8^ *^ l^n^(^1^.^0^4^)^ /^ β^1^)\).

Substituting the values, we find:

m'/m ≈ \(e^(^2^.^7^8^ * ^l^n^(^1^.^0^4^)^ / ^2^.^7^8^)\) ≈ \(e^l^n^(^1^.^0^4^)\) ≈ 1.04.

This means that the expected change in m, when GDP increases by 4%, is approximately 1.04. To express this as a percentage change, we subtract 1 and multiply by 100:

Percentage change = (1.04 - 1) * 100 ≈ 4%.

Therefore, the expected change in m, when GDP increases by 4%, is approximately -2% (rounded to the nearest integer).

Answer:congruent

Step-by-step explanation:

The fraction \($\frac{9}{12}$\) can be expressed as the sum of the smaller fraction \($\frac{3}{4}$\).

Ryan grew \($\frac{1}{2}$\) feet in a year.

1. To express the fraction \($\frac{9}{12}$\) as a sum of smaller fractions, we can simplify it by dividing both the numerator and denominator by their greatest common divisor. In this case, the greatest common divisor of \(9\) and \(12\) is \(3\).

So, we can rewrite \($\frac{9}{12}$\) as:

\($\frac{9}{12} = \frac{3 \times 3}{3 \times 4} = \frac{3}{4}$\)

Therefore, the fraction \($\frac{9}{12}$\) can be expressed as the sum of the smaller fraction \($\frac{3}{4}$\).

2. To find how much Ryan grew in a year, we need to calculate the difference between his height this year and his height last year.

Let's convert the mixed fractions to improper fractions for easier computation:

Last year's height: \($4 \frac{3}{4} = \frac{4 \times 4 + 3}{4} = \frac{19}{4}feet\)

This year's height: \($5 \frac{1}{4} = \frac{5 \times 4 + 1}{4} = \frac{21}{4} feet\)

To determine the growth, we subtract last year's height from this year's height:

\($\frac{21}{4} - \frac{19}{4} = \frac{21 - 19}{4} = \frac{2}{4} = \frac{1}{2}feet\)

Therefore, Ryan grew \($\frac{1}{2}$\) feet in a year.

Answer:

The volume of the cylinder is \(300\pi\) cubic feet.

Step-by-step explanation:

From Geometry we remember that volumes of a cone and a cylinder with the same radius (\(R\)), measured in feet, and height (\(h\)), measured in feet, are defined by the following equations:

Cone

\(V_{co} = \frac{1}{3}\pi\cdot R^{2}\cdot h\) (1)

Cylinder

\(V_{cy} = \pi\cdot R^{2}\cdot h\) (2)

The ratio of the volume of the cylinder to the volume of the cone is:

\(\frac{V_{cy}}{V_{co}} = 3\) (3)

If we know that \(V_{co} = 100\pi\,ft^{3}\), then the volume of the cylinder is:

\(V_{cy} = 3\cdot V_{co}\)

\(V_{cy} = 300\pi\,ft^{3}\)

The volume of the cylinder is \(300\pi\) cubic feet.

In a nearby college, 70% of the understudies live in the dorms. For a specific study, a 100-student random sample is chosen. The standard error of proportion is 0.0459.

A statistic called the standard error of a proportion tells how much a particular sample proportion is likely to differ from the population proportion, p.

In the question, we have given:

\(n=100\\p=70%\)

Population mean, μ = p

That means,

μ = 70%

μ = 0.7

The formula for calculating the standard error of proportion is:

σ = \(\sqrt{\frac{p(1-p)}{n} }\)

When we add the values to the equation above, we get:

σ = \(\sqrt{\frac{0.7*(1-0.7)}{100} }\)

σ = \(\sqrt{\frac{0.7*0.3}{100} }\)

σ = \(\sqrt{\frac{0.21}{100} }\)

σ = \(\sqrt{0.0021}\)

σ = 0.0459

Step-by-step explanation:

The real zeros of the polynomial function P(x) = x⁵ − 50x³ + 49x are -1, 0, and 1.

To find the zeros of this function, we can factor it by first factoring out an x to get P(x) = x(x⁴ − 50x² + 49). Then, we can factor the quadratic expression inside the parentheses using the difference of squares formula, which gives us P(x) = x(x² − 1)(x² − 49). Simplifying further, we have P(x) = x(x − 1)(x + 1)(x - 7)(x + 7).

Therefore, the zeros of P(x) are the values of x that make each factor equal to zero. This gives us x = -7, -1, 0, 1, and 7. Since all of these values are real, we conclude that the number of real zeros of P(x) is 5.

Answer:

\(y = x - 8\)

Step-by-step explanation:

Slope-intercept form is:

\(y = mx + b\)

Where m = slope and b = y-intercept.

It is stated that the slope of the line is 1.

It is stated that the line includes the point (0, 8)

To find the y-intercept, we can just inverse the slope-intercept form to solve for b.

\(b =y-mx\)

We know that the point (8, 0) falls on the line, so that's what we'll use for x and y.

Then, we just have to plug those numbers in, as well as the slope.

\(b = 0 - (1)(8)\)

Simplify.

\(b = 0 - 8\)

Simplify again.

\(b = -8\)

Now, we know that b = -8.

All we have left is to plug the slope and y-intercept into the slope-intercept form.

\(y = x - 8\)

Answer:

whats the question? Could you elaborate a bit more please

Karen is moving at 81.2 miles per hour while Melinda is moving at 71.2 miles per hour.

Speed is the ratio of total distance travelled to total time taken. It is given by:

Speed = distance / time

Let a represent Karen speed and b represent Melinda speed, hence:

a = b + 10

a - b = 10   (1)

Also:

a = d₁ / 1

d₁ = a

b = d₂/ 1 hour

d₂ = b

Since they are 108 miles apart, using Pythagoras:

108² = d₁² + d₂²

a² + b² = 11664

(b + 10)² + b² = 11664

b = 71.2 mph, a = 81.2 mph
