A swimming pool is being filled with water. The diameter of the pool is 27 feet, and the height is 4 feet. Which formula best represents the volume of the pool?
V = pi (13.5) (4)
V = pi (13.5) squared (4)
V = pi (27) (4)
V = pi (27) squared (4)
The expression that best represents the volume is (b) [tex]V = \pi (13.5)^2 (4)[/tex]
How to determine the volume?The given parameters are:
Diameter, d = 27
Height, h = 4
Start by calculating the radius using:
r = d/2
This gives
r = 27/2
r = 13.5
The volume is then calculated as:
[tex]V = \pi r^2 h[/tex]
This gives

Identify the range of the function shown in the graph.
Answer:
D. 0≤y≤5
Step-by-step explanation:
The range refers to how far on the y axis a function exists on a graph. This function starts at y=0 and ends at y=5, meaning you can find a point on the function for any y-level between 0 and 5. So y is greater than or equal to 0, and is less than or equal to 5.
A: A function with a range of all real numbers goes both up and down infinitely, however this function does not go up and down infinitely so we can rule out A.
B: If y>0, the function would start above y-level 0 and go up infinitely, however this graph does not display that so we can rule out B as well.
C: C is the domain of the graph, which is how far left and right the function exists.

What is the inevitable result of running statistical inference on a random sample rather than on an entire population
Your question is incomplete. Please read below to find the complete questin.
B. Sampling error is the inevitable result of running statistical inference on a random sample rather than on an entire population.
A sampling mistake is a statistical blunder that occurs when an analyst does now not pick out a sample that represents the entire population of records. As a result, the outcomes found in the pattern no longer constitute the outcomes that would be received from the entire population.
Sampling error takes place when a sample is chosen from the incorrect populace statistics. Non-reaction errors occur when a user reaction is not received from the surveys. it can happen because of the incapacity to contact capability respondents or their refusal to respond.
The maximum generally used measure of sampling errors is referred to as the same old errors (SE). the standard error is a measure of the spread of estimates across the "true fee". In exercise, only one estimate is available, so the same old blunders can not be calculated at once.

Vortices form in stirred fluids, and may be observed in smoke rings, whirlpools in the wake of a boat, and the winds surrounding a tropical cyclone, tornado or dust devil. Vortices are a major component of turbulent flow. The distribution of velocity, vorticity, as well as the concept of circulation are used to characterise vortices.

The minimum or maximum value of a function is found at the vertex.
The vertex represents either the minimum or maximum point on the graph of the function.
If the quadratic function opens upward, the vertex is the minimum point, and if it opens downward, the vertex is the maximum point.
The x-coordinate of the vertex can be found using the formula x = -b / (2a), where a, b, and c are the coefficients of the quadratic function in the form ax² + bx + c.
Once you find the x-coordinate, you can substitute it back into the function to obtain the corresponding y-coordinate, which represents the minimum or maximum value of the function at the vertex.

Convert 8125 g into kilograms (kg) and grams (g).
Answer:
8125 x 10^-3
= 8.125
8125 g
= 8.125 kg
Step-by-step explanation:
First, note that g is the same as grams and kg is the same as kilograms. Thus, when you are asking to convert 8125 g to kg, you are asking to convert 8125 grams to kilograms.
A gram is smaller than a kilogram. Simply put, g is smaller than kg. In fact, a gram is "10 to the power of -3" smaller than a kilogram.
Since a gram is 10^-3 smaller than a kilogram, it means that the conversion factor for g to kg is 10^-3. Therefore, you can multiply 8125 g by 10^-3 to get 8125 g converted to kg.
Here is the answer with the math showing you how to convert 8125 g to kg by multiplying 8125 by the conversion factor of 10^-3.

A rectangle has integer side lengths. One pair of opposite sides is increased by $30\%$ and the other pair of sides is decreased by $20\%$. The new side lengths are also integers. What is the smallest possible area, in square units, of the new rectangle
The smallest possible area of the new rectangle is 52 square units.
In the question, we are given that a rectangle has side lengths of integral value.
We assume the lengths to be x and y units respectively, such that x and y are integers.
In the new arrangement, one pair is increased by 30%, and the other pair is decreased by 20%, such that the new sides are also integers.
We assume a 30% increase in x.
New side = x + 30% of x = x + 30/100 of x = x + 3x/10 = 13x/10.
For this to be an integer, x needs to be a multiple of 10.
Since we are considering the smallest area, we will consider the smallest multiple of 10, that is, 10 itself.
Hence, side 1 = 13 units.
We assume a 20% decrease in y.
New side = y - 20% of y = y - 20/100 of y = y - y/5 = 4x/5.
For this to be an integer, y needs to be a multiple of 5.
Since we are considering the smallest area, we will consider the smallest multiple of 5, that is, 5 itself.
Hence, side 2 = 4 units.
Now, the area of this rectangle is the product of its sides = 13*4 sq. units = 52 sq. units.
Therefore, the smallest possible area of the new rectangle is 52 square units.

A sales tax of 7% was added to the $36.00 price of a jacket. What was the total cost of the jacket?
a. $36.70
b. $38.10
c. $36.07
d. $38.52
Answer:
[tex]\huge\boxed{\sf \$ \ 38.52}[/tex]
Step-by-step explanation:
Marked price = $36.00
Sales tax = 7%
Sales tax in $:= 7% of marked price
= 7% of $36 [Key: "of" means "to multiply"]
= 7/100 * 36
= 0.07 * 36
= $2.52
Selling price:= Marked price + sales tax
= $36 + $2.52
= $38.52
[tex]\rule[225]{225}{2}[/tex]
The total cost of the jacket was the amount of $38.52. The correct answer is option (d).
To find the total cost of the jacket after adding a 7% sales tax, we need to calculate the tax amount and add it to the original price.
Calculate the tax amount:
Tax amount = 7% of $36.00
Tax amount = 0.07 × $36.00
Tax amount = $2.52
Add the tax amount to the original price:
Total cost = $36.00 + $2.52
Total cost = $38.52
Thus, the total cost of the jacket was the amount of $38.52.
Hence, the correct answer is option (d).
