Step-by-step explanation:

The weighted average total return for the mutual funds covered by Morningstar is 9.20%, calculated by taking the sum of the products of the total return and the number of funds for each of the four categories.

a. The weighted average total return for the mutual funds covered by Morningstar is 9.20%.

This is calculated by taking the sum of the products of the total return and the number of funds for each of the four categories:

(4.65 * 9191) + (18.15 * 2621) + (11.36 * 1419) + (6.75 * 2900) / (9191 + 2621 + 1419 + 2900) = 9.20%

b. Yes, there is a difficulty associated with using the number of funds as the weights in computing the weighted average total return for Morningstar. This is because the number of mutual funds in each category can fluctuate over time, and thus, the weights used to calculate the average total return may not accurately reflect the true performance of the mutual funds.

An alternative to using the number of funds as weights would be to use the dollar amount invested in each type of mutual fund as the weight. This would give a more accurate representation of the performance of the mutual funds.

c. The expected return on the portfolio is 9.63%.

This is calculated by taking the sum of the products of the total return and the amount invested in each of the four categories:

(4.65 * 2000) + (18.15 * 4000) + (11.36 * 3000) + (6.75 * 1000) / (2000 + 4000 + 3000 + 1000) = 9.63%

The weighted average total return for the mutual funds covered by Morningstar is 9.20%, calculated by taking the sum of the products of the total return and the number of funds for each of the four categories. However, using the number of funds as weights may not accurately reflect the true performance of the mutual funds, and an alternative would be to use the dollar amount invested in each type of mutual fund as the weight. The expected return on the portfolio is 9.63%, calculated by taking the sum of the products of the total return and the amount invested in each of the four categories.

The perimeter of the equilateral triangle which has sides of length (3x+7) is 9x+21.

A triangle's three sides and angles must be equal for it to be considered an equilateral triangle.

An equilateral triangle is also referred to as an equiangular triangle because it has angles that are each 60 degrees in length. Because its sides and angles are equal, the equilateral triangle is regarded as a regular polygon or triangle.

Depending on how many sides a triangle has, there are three different types. These triangles are equilateral, isosceles, and scalene.

In an equilateral triangles all sides are equal

so,

perimeter = 3x+7 + 3x+7 + 3x+7

perimeter = 9x+21

Thus, perimeter of the equilateral trinagle which has sides of lenght (3x+7) is 9x+21.

The value of x = 19 and the value of z = 70° in the figure given above.

In algebra, the letter "x" is frequently used to denote an unknown value. It is referred to as a "variable" or occasionally a "unknown.

" x is a variable in x + 2 = 7, but we can figure out its value if we try! A variable can be any letter, name, or symbol; it doesn't have to be "x"; examples include "y" and "w." Z-scores are calculated using the formula z = (x-)/, where x represents the raw score, the population mean, and the population standard deviation.

The z-score is simply the raw score less the population mean, divided by the population standard deviation, as the calculation demonstrates. A raw score's position relative to its distance from the mean is described by the z-score.

Using The property Vertically opposite angles are equal

110° = 9x - 61

⇒ 9x = 110 +61

⇒ 9x = 171

⇒ x = 171/9

⇒ x = 19

As all angles equal 360°

110° + 110° + 2z = 360°

⇒ 2z = 360° - (110° + 110°)

⇒ 2z = 140

⇒ z = 140/2

⇒ z = 140/2

⇒ z = 70°

Thus, The value of x = 19 and the value of z = 70° in the figure given above.

In repeated sampling from the S distribution, the mean of the values will be close to 4.66, which is the appropriate interpretation of the mean.

The arithmetic mean, also known as the arithmetic average or simply the mean or average, is the sum of a set of numbers divided by the total number of numbers in the set. The collection frequently consists of a set of findings from a survey, experiment, or observational study. The average of a group of values is referred to as the mean in mathematics and statistics. There are several methods for calculating the mean, including simple arithmetic means (adding the numbers together and dividing the result by the number of observations), geometric means, and harmonic means.

Answer:

Diameter is 8

Circumference is 8pi ~= 25.13

Step-by-step explanation:



The diameter is double the radius. So the given radius is 4 and double is 8.

The Circumference is given by C = pi•d or C = 2pi•r

Both of these equations will give the circumference.

C = pi•d

= pi•8

= 8pi ~= 25.13

OR

C = 2pi•r

= 2pi•4

= 8pi ~= 25.13

For finding the diameter, I multiply the radius by 2:

Diameter = 2 × radius

                = 2 × 4

                = 8

So the diameter is 8. As for the circumference, we can use two ways : either multiply pi times the diameter, or multiply 2 times pi times the radius.

The formulas are

C = πd              and C = 2πr

To find the circumference, stick in 8 for d:

C = π × 8

C = 25.13 units

We can first simplify the inner parenthesis

[tex]$53\cdot\left(3\frac{1}{5} - 4\frac{1}{2}\right)=53\cdot(-1\frac{1}{10})=-53\frac{11}{10}$[/tex]

Then simplify the denominator, The denominator is the bottom part of a fraction, which represents the total number of parts in the whole. It is used to indicate the size of the fraction's unit or whole. It is also used to divide the numerator (top part of a fraction) by in order to determine the fraction's value.

[tex]$2\frac{3}{4} - 1\frac{2}{3} = \frac{11}{4} - \frac{5}{3} = \frac{44}{12} - \frac{20}{12} = \frac{24}{12} = 2$[/tex]

Now we can divide -53 and 11/10 by 2

[tex]$-53\frac{11}{10} \div 2 = -53\frac{11}{20} = -\frac{1133}{20} = -56\frac{13}{20}$[/tex]

(A)=A/6 =0

Step-by-step explanation:

If 3 inches on the map represents 1.25 miles, we can use that proportion to find how many inches represents 10 miles.

3 inches / 1.25 miles = x inches / 10 miles

We can cross multiply and divide to find x:

x = (3 inches * 10 miles) / 1.25 miles

x = 24 inches

So on the map, 24 inches represent 10 actual miles.

The range is not likely to vary, which is one of the claims regarding the new salary distribution that is supported.

Therefore,

Given that a small company's salary distribution of 27 employees has a mean of $35,000 and a standard deviation of $2,000,

When a highly unusual value, such as 120000, is taken into account for the 28th employee, we discover that the mean increases.

The new median would be the average of items 14 and 15, as the prior median was the 14th item. Thus, the median may alter.

Because the maximum has been raised up to 120000, the range will undoubtedly vary.

Range changes, median changes, and mean increases.
