All digits in a dropdown number are different and one of its digits is the average of all its digits. It has at least two digits. For example, 5021 is a dropdown number, but neither 4389 nor 6033 is a dropdown number. How many 3 digit dropdown numbers are there?
Answer:
112
Step-by-step explanation:
You want the number of 3-digit "dropdown numbers".
Dropdown numberA "dropdown number" has distinct digits, one of which is the average of all digits.
We can count the number of dropdown numbers by considering the digit that is the average of the rest. For that digit (n), the number of possible choices of the other digits is the lesser of (n) or (9-n). For example, for n=2, we can have other digit pairs of (0, 4) or (1, 3). For n=6, we can have other digit pairs of (5, 7) or (4, 8) or (3, 9).
CountingThe value of n may range from 1–8, inclusive, so the number of digit triples will be 2(1 +2 +3 +4) = 20. Each triple of digits can be arranged 6 ways, for a total of 20·6 = 120 numbers of 3-digits.
Of those, 8 numbers will have a leading 0, so may not count as 3-digit numbers. That leave a total of 120 -8 = 112 3-digit dropdown numbers.

There are two imaginary roots and one real root of the equation
What is the root of an equation?Generally, In mathematics, the root of an equation is a value that satisfies the equation. In other words, it is the value of the variable for which the equation is true. For example, in the equation x^2 - 4 = 0, the roots are +2 and -2, because when either of these values is substituted for x, the equation becomes true.
There are different methods for finding roots of an equation, depending on the type of equation. For example, some equations can be solved by factoring, while others require the use of more advanced techniques such as the quadratic formula or numerical methods like the Newton-Raphson method.
In general, finding the roots of an equation is an important task in mathematics and has many practical applications in fields such as engineering, physics, and finance.

the standard deviation is a resistant measure of spread. t/f
True, the standard deviation is a resistant measure of spread.
The standard deviation is calculated as the square root of the variance of the data set. Variance is calculated as the average of the squared differences between each data point and the mean of the data set. The standard deviation is the square root of this average.
In mathematical terms, the standard deviation can be calculated using the following formula:
σ = √(1/n ∑(x - μ)²)
Where σ is the standard deviation, n is the number of data points in the data set, x is the value of the i-th data point, and μ is the mean of the data set.
The standard deviation is an important measure because it gives an idea of how much the individual values in a data set differ from the mean.
In summary, the standard deviation is a resistant measure of spread because it gives a robust measure of the spread of the data in a set and is not easily influenced by outliers or extreme values.

Superior segway tours gives sightseeing tours around chicago, illinois. it charges a one-time fee of $60, plus $28 per hour. what is the slope of this situation? a. 28 b. 32 c. 60d. 88
Answer:
the answer is (a) 28.
Step-by-step explanation:
The given situation can be represented by a linear equation of the form:
Cost = mx + b
where "m" is the slope (the rate of change of cost with respect to time), "x" is the number of hours of the tour, and "b" is the y-intercept (the cost when x = 0).
In this case, the y-intercept is $60, which represents the one-time fee. The cost increases by $28 per hour, so the slope is:
m = $28/hour
Therefore, the answer is (a) 28.

what is the value of 77 degrees f in c?
The value of 77 degrees Fahrenheit (°F) is equal to 25 degrees Celsius (°C).
The conversion from Fahrenheit to Celsius involves a simple mathematical formula, which is as follows:
°C = (°F - 32) x 5/9
In this formula, °F represents the temperature in degrees Fahrenheit, while °C represents the temperature in degrees Celsius.
To convert 77 degrees Fahrenheit to Celsius, we first plug in the value of 77 for °F:
°C = (77 - 32) x 5/9
Next, we simplify the expression inside the parentheses:
°C = 45 x 5/9
We can simplify this further by multiplying 45 and 5/9:
°C = 225/9
We can then simplify this fraction by dividing both the numerator and denominator by the greatest common factor, which is 9:
°C = 25
Therefore, we conclude that 77 degrees Fahrenheit is equivalent to 25 degrees Celsius.

25 points! the radius r of a sphere with volume v is given by r= (3v/4π)
find the radius of a ball that hold 66 cubic centimeters of air.
Answer:
To find the radius of a ball that holds 66 cubic centimeters of air:
1. Substitute the given volume into the equation r= (3v/4π): r = (3*66/4π).
2. Simplify the equation: r = (198/4π).
3. Calculate the value of 4π: 4π = 12.57.
4. Divide 198 by 12.57: r = 15.75.
5. The radius of the ball that holds 66 cubic centimeters of air is 15.75 cm.
Answer:
Step-by-step explanation:
To find the radius of a sphere that holds 66 cubic centimeters of air, we can use the formula provided in the question:
r = (3v/4π)
where v is the volume of the sphere. We are given that the volume of the sphere is 66 cubic centimeters, so we can substitute this value into the formula:
r = (3 x 66) / (4 x π)
Simplifying this expression:
r = 198 / (4π)
Using a calculator to evaluate this expression:
r ≈ 15.8267
Therefore, the radius of the sphere that holds 66 cubic centimeters of air is approximately 15.8267 centimeters.

C) The volume of the pyramid is 9 times larger than the prism.
D) The volume of the pyramids is 1/3 times larger than the prism.
Yhe volume of both the prism and the pyramid are the same. The right response is B, which states, "The volume of both shapes is the same."
What is the straightforward meaning of volume?
Three-dimensional space is occupied by everything. Here, the volume of the space is calculated. A three-dimensional object's volume is the area included inside its bounds. It is also referred to as an object's capability occasionally.
[tex]\mathrm{h_{py} = 3 \times h_p}[/tex]
The volume of the prism is given by:
[tex]V_p[/tex] = base area × height = 4 cm² × [tex]h_p[/tex]
The volume of the pyramid is given by:
[tex]\mathrm{V_{py}}[/tex] = (1/3) * base area * height = (1/3) * 4 cm² * [tex]h_{py[/tex]
Using the equation for [tex]h_{py[/tex] from above, we can substitute:
[tex]\mathrm{V_{py}}[/tex] = (1/3) * 4 cm² * 3 * [tex]h_p[/tex] = 4 cm² * [tex]h_p[/tex] = [tex]V_p[/tex]

What is 576 square root by division method?
Answer:
√576 = 24
Step-by-step explanation:
You want to find the square root of 576 by the long division method.
MethodThe attachment shows the result of applying the method.
The dividend is marked off in 2-digit groups working outward from the decimal point. An overline is typically used. Here, 76 is the group closest to the decimal point, and the next "group" is 5The integer part of the square root of the leftmost 2-digit group is written as the leftmost digit of the root. Here the integer part of the square root of 5 is 2, so that is the first root digit.The quotient digit is appended to the divisor, and the result is multiplied by the root digit. For the first step here, the digit 2 is appended to 0, and multiplied by the root digit 2. The product, 4, is subtracted from the dividend so far, and the next 2-digit group is appended to the result to form the next "dividend."The root so far is doubled and written as the first digits of the new divisor. This will be 2·2 = 4, with space left to append the next root digit: 4_.The next root digit is the largest integer that can be appended to the divisor, and multiplied by that divisor to obtain a value that is at most equal to the "dividend." Here, the second digit of the root is 4, and 44 · 4 = 176. This value is subtracted from the dividend resulting from step 3. Here, they are equal, so the difference is zero, and we're done. If there are more digits and/or the difference is not zero, then the process is repeated from step 3.The root of 576 is 24.
