Variance matters a lot in various fields, and it is important to understand the concept of variance to make informed business decisions.
Variance matters a lot in the field of statistics, finance, and business. This term is generally used to determine the level of difference between the actual and the expected values or outcomes. Variance can help us understand the level of risk associated with a particular investment or business decision, and also helps us to analyze the accuracy of the predictions we make.
Example:
Suppose a stockbroker recommends that a client invests in a particular stock, and the client is considering investing in that stock. The stockbroker provides an expected return rate of 10%. However, if the actual return rate ends up being 15%, the client will be very happy, but if it ends up being only 5%, the client will be very unhappy. Thus, it is important for the stockbroker to consider the variance in the expected return rate and to provide an explanation of the level of risk associated with the investment.
Another example is when a company has a budget of $100,000 for advertising, and the marketing team spends $110,000 on advertising. The company's management can calculate the variance of $10,000 to determine whether the marketing team exceeded the budget or not. The variance can help the company to adjust its future marketing strategies to achieve the desired results.
Thus, variance matters a lot in various fields, and it is important to understand the concept of variance to make informed business decisions.

Answer:
(√122 - √10)/112.
Step-by-step explanation:
The average rate of change of a function f(x) over an interval [a, b] is given by:
average rate of change = (f(b) - f(a))/(b - a)
Here, we have f(x) = √x - 1, a = 10, and b = 122. So, the average rate of change of f(x) from x = 10 to x = 122 is:
(f(122) - f(10))/(122 - 10)
= (√122 - 1 - √10 + 1)/(112)
= (√122 - √10)/112
Therefore, the exact, fully simplified answer for the average rate of change of f(x) from x = 10 to x = 122 is (√122 - √10)/112.
You need a 30% alcohol solution. On hand, you have a 675 mL of a 5% alcohol mixture. You also have 75% alcohol mixture. How much of the 75% mixture will you need to add to obtain the desired solution?
you will need____mL for the 75% solution
You need to add 225mL of the 75% alcohol solution to obtain the desired 30% alcohol solution.
To find the amount of 75% alcohol solution needed to obtain a 30% alcohol solution, we must use the formula for dilution:
M1V1 = M2V2
Where M1 is the concentration of the initial solution, V1 is the volume of the initial solution, M2 is the desired concentration, and V2 is the desired volume.
In this case, M1 is 5%, V1 is 675mL, M2 is 30%, and V2 is unknown.
We can rearrange the equation to solve for V2, which is the volume of the 75% alcohol solution needed:
V2 = (M1V1) / M2
V2 = (5% x 675mL) / 30%
V2 = 225mL

Suppose the events Upper B 1, Upper B 2, and Upper B 3, are mutually exclusive and complementary events, such that P(Upper B 1)equals0. 05, P(Upper B 2)equals0. 4, and P(Upper B 3)equals0. 55. Consider another event A such that P(A|Upper B 1)equals0. 6, P(A|Upper B 2)equals0. 5, and P(A|Upper B 3)equals0. 4. Use Bayes's Rule to find P(Upper B 1|A)
The probability of event Upper B 1 given event A is approximately 0.0134.
To find P(Upper B 1|A) using Bayes' rule, we need to use the formula:
P(Upper B 1|A) = P(A|Upper B 1) × P(Upper B 1) / P(A)
To find P(A), we can use the law of total probability:
P(A) = P(A|Upper B 1) × P(Upper B 1) + P(A|Upper B 2) × P(Upper B 2) + P(A|Upper B 3) × P(Upper B 3)
Substituting the given values, we get:
P(A) = 0.6 × 0.05 + 0.5 × 0.4 + 0.4 × 0.55
P(A) = 0.029 + 0.2 + 0.22
P(A) = 0.449
Now, substituting the values of P(A|Upper B 1), P(Upper B 1), and P(A) into the Bayes' rule formula, we get:
P(Upper B 1|A) = (0.6 × 0.05) / 0.449
P(Upper B 1|A) = 0.006 / 0.449
P(Upper B 1|A) ≈ 0.0134
Therefore, the probability of event Upper B 1 given event A is approximately 0.0134.

The picture in this question can be a little deceiving. Each rectangular glass pane is 3 by 10 inches. This means that the picture of the 4 panes overlapping, leaves the center square open. The open area has your inner edges. The question asks for the sum of the inner and outer edges.
Every pane is 10 inches long, so the out perimeter of the figure is 40 inches because the figure has four sides. The rectangles overlap, creating 3 by 3 inch square. 3 inches off either side of a pane leaves 4 inches as the length for the edge of the inner square. Therefore, the perimeter of the inner square is 16 inches.
Outer Perimeter + Inner Perimeter = 40 + 16 = 56 inches
Lara's Burgers cooks its burgers either well done or medium. Last night, the restaurant served 9 well-done burgers and 11 medium burgers. What percentage of the burgers served were well done?
45% of the burgers served were well-done.
What is percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
To find the percentage of well-done burgers, we need to divide the number of well-done burgers by the total number of burgers served and then multiply by 100 to get the percentage.
Total number of burgers served = 9 well-done + 11 medium = 20
Percentage of well-done burgers = (9/20) x 100% = 45%
Therefore, 45% of the burgers served were well-done.

The APR on the loan, given the amount you are to pay in interest every day, can be found to be 190. 54 %
How to find the APR ?To calculate the APR (Annual Percentage Rate) for this loan, we need to know the total interest paid over the course of a year, as a percentage of the loan amount.
First, we need to determine the total interest paid over the course of one year. Since the interest rate is $3.98 per day, we can multiply that by the number of days in a year (365) to get the total interest paid per year:
$3.98 x 365 = $1, 452.70
The APR would therefore be :

Assume that the test scores of a college entrance test fits a normal distribution. The mean test score is 72, and the standard deviation is 15.2 a)What is the percentage of students scoring 84 or more? b) If a random student is chosen. What is the probability of the student scoring an 84 or more on the test if the max score was 95?
The probability of a random student scoring 84 or more if the maximum score is 95 is approximately 0.1179 or 11.79%.
To find the percentage of students scoring 84 or more, first we need to calculate the z-score using the formula:z = (X - μ) / σwhere X = 84, μ = 72, and σ = 15.2z = (84 - 72) / 15.2z = 0.7895Using a standard normal table or a calculator, we can find the percentage of students scoring 84 or more as:percentage = 1 - P(Z < 0.7895)percentage ≈ 21.4%Therefore, approximately 21.4% of students will score 84 or more on the test.b) To find the probability of a random student scoring 84 or more if the maximum score is 95, we need to first calculate the z-score using the same formula as before:z = (X - μ) / σwhere X = 84, μ = 72, and σ = 15.2z = (84 - 72) / 15.2z = 0.7895Then, we need to convert this z-score to a new z-score based on the maximum score of 95. Using the formula:z = (X - μ) / (max score - μ)σwhere X = 84, μ = 72, σ = 15.2, and max score = 95z = (84 - 72) / (95 - 72)z ≈ 1.19Using a standard normal table or a calculator, we can find the probability of a student scoring 84 or more as:P(Z > 1.19)P(Z > 1.19) ≈ 0.1179Therefore, the probability of a random student scoring 84 or more if the maximum score is 95 is approximately 0.1179 or 11.79%.

30 dollars to spend on 3 gifts. She spent 8 9/10 dollars on gift A and 6 3/5 dollars on gift B. How much money did she have left for gift C?
From the given information provided, she has 14.50 dollars money left to spend on gift C.
To find out how much money is left for gift C, we first need to add up the amounts spent on gift A and gift B:
8 9/10 dollars + 6 3/5 dollars = (8 + 6) + (9/10 + 3/5) dollars
= 14 + (9/10 + 6/10) dollars
= 14 + 15/10 dollars
= 15 5/10 dollars
= 15.50 dollars
So the total amount spent on gift A and gift B is 15.50 dollars. To find out how much money is left for gift C, we need to subtract this amount from the total amount she has to spend:

Answer:
[tex]P = 56\sqrt2[/tex]
Step-by-step explanation:
We can find the perimeter of a square given its diagonal by modeling the square as two congruent right triangles and using the Pythagorean Theorem to solve for the square's side lengths.
The Pythagorean Theorem states that...
[tex]a^2+b^2=c^2[/tex], where [tex]a[/tex] and [tex]b[/tex] are the right triangles legs, and [tex]c[/tex] is its hypotenuse.
However, since we are working with a square, we know that the right triangles' legs are congruent. Thus, the theorem becomes:
[tex]a^2 + a^2 = c^2[/tex]
[tex]2 \cdot a^2 = c^2[/tex]
Using this formula, we can solve for the square's side lengths, inputting the given hypotenuse length of 28.
[tex]2 \cdot a^2 = 28^2[/tex]
↓ simplify the exponent
[tex]2 \cdot a^2 = 784[/tex]
↓ divide both sides by 2
[tex]a^2 = 392[/tex]
↓ take the square root of both sides
[tex]a = \sqrt{392}[/tex]
↓ simplify the square root
[tex]a = \sqrt{2^3 \cdot 7^2}[/tex]
[tex]a = (2\cdot 7)\sqrt{2}[/tex]
[tex]a=14\sqrt2[/tex]
Finally, we can multiply the side length by 4 to get the square's perimeter (since a square has 4 sides).
[tex]P = 4 \cdot a[/tex]
[tex]P = 4 \cdot 14\sqrt2[/tex]
[tex]\boxed{P = 56\sqrt2}[/tex]
[tex]\boxed{P \approx 79.2}[/tex]

B) 5x^3 - 4x^2 + 3x - 12
C) 5x^3 - 4x^2 + 3x + 12
D) 5x^3 - 4x^2 + 3x + 4
Answer:
Part A:
To find the total length of sides 1 and 2 of the triangle, we need to add the lengths of these sides:
Side 1 + Side 2 = (3x^2 - 4x - 1) + (-x^2 + 4x + 5)
Simplifying the expression by combining like terms, we get:
Side 1 + Side 2 = 2x^2 + 1
Therefore, the total length of sides 1 and 2 of the triangle is 2x^2 + 1.
Part B:
To find the length of the 3rd side of the triangle, we can subtract the sum of sides 1 and 2 from the perimeter of the triangle:
5x^3 - 2x^2 + 3x - 8 - [(3x^2 - 4x - 1) + (-x^2 + 4x + 5)]
Simplifying the expression by distributing the negative sign, and then combining like terms, we get:
5x^3 - 2x^2 + 3x - 8 - 2x^2 + 8x + 4
Simplifying further by combining like terms, we get:
5x^3 - 4x^2 + 11x - 4
Therefore, the length of the 3rd side of the triangle is 5x^3 - 4x^2 + 11x - 4.
Answer:
A) 5x^3 - 4x^2 + 3x - 4

Therefore, the total length of sides 1 and 2 of the triangle is 2x^2 + 1.
Part B:
To find the length of the 3rd side of the triangle, we can subtract the sum of sides 1 and 2 from the perimeter of the triangle:
5x^3 - 2x^2 + 3x - 8 - [(3x^2 - 4x - 1) + (-x^2 + 4x + 5)]
Simplifying the expression by distributing the negative sign, and then combining like terms, we get:
5x^3 - 2x^2 + 3x - 8 - 2x^2 + 8x + 4
Simplifying further by combining like terms, we get:
5x^3 - 4x^2 + 11x - 4
Therefore, the length of the 3rd side of the triangle is 5x^3 - 4x^2 + 11x - 4.

To fully describe a triangular prism, you would need to provide the dimensions of its triangular bases (e.g. base length and height), the length of the prism, and the length and width of the rectangular faces. Thus, option C is correct.
What is the triangular prism with dimensions?To find the volume of filler material required to surround the triangular prism, we need to first calculate the volume of the box and the volume of the triangular prism.
The volume of the box is given by:
[tex]8[/tex] inches × [tex]13[/tex] inches × [tex]16[/tex] inches = [tex]1,664[/tex] cubic inches
The volume of the triangular prism is given by:
[tex](1/2) × 8[/tex] inches × [tex]13[/tex] inches × [tex]16[/tex] inches = [tex]832[/tex] cubic inches
To completely fill the box, we need to add filler material with a volume equal to the difference between the volume of the box and the volume of the triangular prism, which is:
cubic inches— [tex]832[/tex] cubic inches [tex]= 832[/tex] cubic inches
Therefore, the [tex]832[/tex] Cubic inches.
