Which one of the following procedures will be able to calculate the average value of a population without statistical error?
A Random Sampling B Systematic Sampling C Census D Cluster Sampling
Answers
Random Sampling will be able to calculate the average value of a population without statistical error.
What do you mean by random sampling?Each sample has an equal chance of being chosen when using the sampling technique known as random sampling.
When there is little chance of data manipulation, systematic sampling is employed.
A census is a study of every element, person, or aspect of the population.
When a population is divided into clusters, a sample is chosen at random from within each cluster. This process is known as cluster sampling.
Hence, we use Random sampling for not getting statistical errors.

how much fuel will you need to travel 75 sm if your airplane burns 3 gallons of fuel/hr. and your groundspeed is 45 mph?
Answers
Using Simple Speed formula,
To travel the distance of 75m with an airplane will need five gallons of fuel .
We have given that,
An airplane, fuel burn speed = 3 gallons of fuel per hour
ground speed of airplane = 45mph
distance = 75m
Speed = distance /time = 45 mph
=> 45 m distnce in one hour
fuel consumption of airplane = 3gallons/h
from above discussion we get,
fuel consumption for 45 m is equal to 3 gallons .
we have to calculate the quantity of fuel need to travel 75 m .
Now, 45 m distnce implies 3 gallons fuel consumption
1 m distance implies 3/45 gallons of fuel consumption
fuel consumption for 75 m =( 3/45)×75 = 5 gallons
Hence, 5 gallons fuel we need to travel 75 m .

How do you find the vertical asymptote of an exponential function?
Answers
There is no the vertical asymptote of given exponential function.
How to find the vertical asymptote of an exponential function?Consider the fact that the exponential function's domain is x ∈ R in order to identify its vertical asymptote. There is thus no value of x for which y is not true. Therefore, there is no vertical asymptote for the exponential function.
Assume that x is the variable and that f(x)=ax is an exponential function.
So let's determine the domain for x; it is x ∈ R for an exponential function, where R is the set of real numbers.
As a result, the exponential function has no vertical asymptote (as there is no value of x for which it would not exist).
However, the horizontal asymptote occurs at y=0 as lim ax=0 if we talk about it. x→∞
As a result, the exponential function has no vertical asymptote.

Apples are prepared in a process with two resources. The first resource has a capacity of 2.1 apples per hour. The capacity of the second resource is 4.4 apples per hour. The first resource has 1 worker and the second resource has 4 workers. Demand for this process is 1.6 apples per hour. Wages are $8 per hour.
What is the cost of direct labor (in $)?per unit
Answers
The cost of direct labor per unit is $5.628 per apple.
To calculate the cost of direct labor per unit, we need to determine the total labor hours required to produce one unit of output and then multiply it by the wage rate.
Let's denote the labor hours required for the first resource as "L₁" and the labor hours required for the second resource as "L₂".
The first resource has a capacity of 2.1 apples per hour, and the demand is 1.6 apples per hour. Therefore, the labor hours required for the first resource per unit of output are:
L₁ = 1 apple / (2.1 apples/hour) = 0.4762 hours/apple (rounded to 4 decimal places)
The second resource has a capacity of 4.4 apples per hour, and the demand is 1.6 apples per hour. Therefore, the labor hours required for the second resource per unit of output are:
L₂ = 1 apple / (4.4 apples/hour) = 0.2273 hours/apple (rounded to 4 decimal places)
Now, let's calculate the total labor hours required per unit:
Total labor hours per unit = L₁ (first resource) + L₂ (second resource)
= 0.4762 hours/apple + 0.2273 hours/apple
= 0.7035 hours/apple (rounded to 4 decimal places)
Finally, to calculate the cost of direct labor per unit, we multiply the total labor hours per unit by the wage rate:
Cost of direct labor per unit = Total labor hours per unit * Wage rate
= 0.7035 hours/apple * $8/hour
= $5.628 per apple (rounded to 3 decimal places)

A toy train set has a circular track piece. The inner radius of the piece is 6 cm. One sector of the track has an arc length of 33 cm on the inside and 55 cm on the outside. What is the width of the track? *respost since people thought it would be funny to troll on my last. :/
Answers
The width of the toy train track is 4 cm.
To find the width of the toy train track, we need to consider the inner radius, the arc length of the inner sector, and the arc length of the outer sector.
Given:
Inner radius (r1) = 6 cm
Inner arc length (s1) = 33 cm
Outer arc length (s2) = 55 cm
Step 1: Find the central angle (θ) using the inner arc length and inner radius.
θ = s1/r1 = 33 cm / 6 cm = 5.5 radians
Step 2: Find the outer radius (r2) using the central angle and the outer arc length.
s2 = r2 × θ
55 cm = r2 × 5.5 radians
r2 = 55 cm / 5.5 radians = 10 cm
Step 3: Calculate the width of the track.
Width = Outer radius - Inner radius
Width = r2 - r1 = 10 cm - 6 cm = 4 cm
The width of the toy train track is 4 cm.

2 and StartFraction 3 Over 16 EndFraction hours
5 and three-fifths hours
10 and two-fifths hours
Answers
Answer:
We can start by isolating the variable "h".
5 8 h + 1 1 2 = 5
Subtracting 11/2 from both sides:
5 8 h = 5 - 1 1 2
Simplifying:
5 8 h = 8 1 2
Dividing both sides by 5/8:
h = 8 1 2 ÷ 5 8
Converting the mixed number to an improper fraction:
h = (8 x 8 + 1) ÷ 5 8
h = 65/8
Now, we can convert this fraction to a mixed number:
h = 8 1/8
Brigid has already picked for 8 1/8 hours, so the amount of time needed to pick the remaining strawberries is:
5 - (1 1/2 + 5/8 x 8) = 5 - (3 5/8) = 1 3/8
Therefore, Brigid still needs to pick for 1 3/8 hours to fill 5 bushels of strawberries. The answer is 1 and 3/8 hours or 2 and 3/16 hours (if simplified).

A radical expression is an expression that contains a radical symbol (√) which represents a square root or higher-order root of a number or expression.
The expression under the radical symbol is called the radicand. Radical expressions can also include variables and exponents.
For example, √25 is a radical expression, where 25 is the radicand and the radical symbol represents the square root.
Another example is ∛(x^2+2x+1), where x^2+2x+1 is the radicand and the radical symbol represents the cube root.
