What is the variance of 2 4 6 8 10?
The variance of 2, 4, 6, 8, 10 is 8.
To calculate the variance of a set of numbers, you first need to calculate the mean of the set. The mean of 2, 4, 6, 8, 10 is 6. Then, for each number in the set, you need to calculate the difference between that number and the mean, and square the result. Finally, you need to sum those squared differences and divide by the number of items in the set.
Here's the calculation:
(2 - 6)^2 + (4 - 6)^2 + (6 - 6)^2 + (8 - 6)^2 + (10 - 6)^2 = (-4)^2 + (-2)^2 + 0^2 + (2)^2 + (4)^2 = 16 + 4 + 0 + 4 + 16 = 40
40 / 5 = 8
So, the variance of 2, 4, 6, 8, 10 is 8.
How does variance work?Variance is a statistical measurement of the variation in numbers within a data set. Variance, in more precise terms, indicates how far apart any number in the set is from both the mean (average) and, consequently, from every other number in the set.

What is equal to 3 minus square root of eight divided by square root of 3
Answer:
approximately 1.732
Step-by-step explanation:
To solve this expression, we need to start by performing the operations inside the parentheses first. The square root of 8 is equal to 2, so 3 minus 2 is equal to 1. Then, we can divide 1 by the square root of 3, which is equal to approximately 1.732. Therefore, the expression 3 minus square root of eight divided by square root of 3 is equal to approximately 1.732.
I need to know the unit price for both a and b and what’s the better buy
Answer:
Brand A Forks $0.08, Brand B Forks $0.06, Better Buy is Brand B
Step-by-step explanation:
Unit price is price per unit (in this case, forks)
You need to find the $ for 1 fork for Brand A and B, since they have different unit prices.
total price/units = price/unit
Brand A: $1.97/25 forks = $0.0788 (rounded up is $0.08)
Brand B: $2.98/48 forks = $0.06208 (rounded up is $0.06)
Better brand is Brand B because it is cheaper.
Determine the domain and range for the function below.
Answer:
Domain: (-∞, ∞); Range: [1, ∞)
Step-by-step explanation:
Domain is the set/interval of x-values that the function spans while the range is the set or interval of y-values that the function spans.
Domain
We can see that the arrows point towards negative and positive infinity for x and also see there are no holes or asymptotes for this graph. Therefore, the domain is (-∞, ∞) or {x | x is any real number}
Range
We can see that the arrows both point towards infinity for y-values and that the lowest y-value this graph touches is y = 1 (inclusive, meaning this y-value is included in the range). Thus, the range is [1, ∞) or {y | y ≥ 1}

ounces, of the substance that is left after t years can be modeled by the equation y = 1800e-0.00052t
where y is the amount of the substance left after t years.
Approximately how many years will it take until 80 ounces of this substance remains?
According to the given statement 2.622 years will it take until 80 ounces of this substance remains.
How much does one ounce weigh?Use a test tube holder that has an ounce marker or can be converted quickly to ounces (like cups). As you take the measuring cup from the ingredient, let it overflow. You may try and reduce measurement afterwards. Use a knife to level the measuring cup.
Briefing:The equation may be used to predict how much of the chemical is still present after t years, measured in ounces.
y=1800e -0.00052t
In the equation above, we substitute y = 80 ounce to obtain the time.
80= 1800e -0.00052t
80/1800=e -0.00052t
2/45= e -000.52t
Considering both ends of the aforementioned equation
In(2/45)= In(e -000.52t)
In(2)-In(45)= In(e -000.52)
0.3010-1.653= -000.52t

The asymptotes for the given function f(x) = 7/(x^2-2x-24) are located at
x = -3 and x = 8.
The asymptotes of a function are the lines that the graph approaches, but never touches as it continues to infinity. In the given function, f(x) = 7/(x^2-2x-24), the asymptotes are located at x = -3 and x = 8.
To find the asymptotes of a function, you first need to factor the denominator of the function. In this case, the denominator is[tex]x^2-2x-24,[/tex]which can be factored into (x+3)(x-8). This means that there are two potential zeroes in the denominator, x=-3 and x=8. These two points are the two asymptotes of the graph of the given function.
To explain further, the two asymptotes divide the x-axis into three intervals. On the interval (-infinity, -3), the graph of the function will approach negative infinity as x approaches -3 from the left. On the interval (-3, 8), the graph of the function will approach positive infinity as x approaches 8 from the right. On the interval (8, infinity), the graph of the function will approach negative infinity as x approaches 8 from the right.
In summary, the asymptotes for the given function f(x) = 7/(x^2-2x-24) are located at x = -3 and x = 8.

To demonstrate how to solve a radical equation, let's use the following equation as an example:
The m∠BOD = 46 and the m∠BOC = 26. What is the m∠COD?
The measure of the angle m∠COD is 20 degrees
How to determine the measure of the angle m∠COD?From the question, we have the following parameters that can be used in our computation:
The measures of the angles:

The measure of the angle m∠COD is the difference between of the above angles
Using the above as a guide, we have the following:
Measure of the angle m∠COD = Difference of angles m∠BOD and m∠BOC
Mathematically, this is represented as
Measure of the angle m∠COD = m∠BOD - m∠BOC
Substitute the known values in the above equation, so, we have the following representation

The relationship between the volume of a rectangular prism and pyramid is defined as that the pyramid takes up 1/3 of the volume of a prism.
Here we need to identify the relationship between the volume of a rectangular prism and pyramid.
As we all know that the volume of rectangle prism is written as,
=> Volume of a prism = (area of base) * height
Now, let us consider the volume of a pyramid that the pyramid takes up 1/3 of the volume of a prism when their bases and height are equal.
So, here the volume of a pyramid is 1/3 multiplied by the volume of a prism.

Clark's rule is a formula used to determine pediatric doses of over the counter medicine.
The formula says

the recommended range of doses?
A. x≤ 600
B. x ≥ 600
C. 500
D. 500 ≤x≤ 600
500 ≤x≤ 600 is the recommended range of doses. Typically, a phase I or early phase II clinical trial involves dose range.
How to calculate doses ?To solve this problem using Clark's rule, we need to determine the range of pediatric doses for a child who weighs less than 90 pounds and for whom the adult dose is 1,000 mg.
A mathematical formula known as Clark's rule is used in medicine to determine the right dosage of medication for patients aged 2 to 17 depending on their weight and the recommended adult dose.
First, we can use the formula provided to calculate the child dose:
Child dose = (Weight of child / 150) * Adult dose
Since the weight of the child is less than 90 pounds, we can set the weight of the child to the minimum value in the range, which is 50 pounds. This gives us:
Child dose = (50 / 150) * 1000 mg
= 333.33 mg
Next, we can set the weight of the child to the maximum value in the range, which is 89 pounds. This gives us:
Child dose = (89 / 150) * 1000 mg
= 593.33 mg
Therefore, the recommended range of doses for a child who weighs less than 90 pounds and for whom the adult dose is 1,000 mg is 500 mg ≤ x ≤ 600 mg.
So, the correct answer is D. 500 ≤x≤ 600.
