The statement is not true because random sampling does not eliminate all potential sources of bias and variability in the sample selection process.
Other factors and variables that influence study outcomes include sampling bias, sample size, sampling frame, selection methods, population heterogeneity, and study design and execution.
The statement that random sampling guarantees a representative sample of the population is not entirely true.
While random sampling is a valuable method to increase the likelihood of obtaining a representative sample, it does not provide an absolute guarantee.
There are several factors and variables that can influence the outcomes of studies, even with random sampling.
Sampling Bias: Despite random sampling, certain biases can still occur. For example, non-response bias can arise if selected individuals choose not to participate or are unavailable, which can lead to a non-representative sample.
Sample Size: The size of the sample plays a crucial role in its representativeness.
If the sample size is too small, it may not accurately reflect the diversity and characteristics of the population, leading to biased results.
Sampling Frame: The sampling frame refers to the list or method used to identify potential participants.
If the sampling frame is incomplete or inaccurate, the resulting sample may not be representative of the entire population.
Selection Methods: Random sampling is just one method of selecting a sample. Other sampling methods, such as stratified sampling or convenience sampling, may introduce additional biases and affect the representativeness of the sample.
Population Heterogeneity: The variability and diversity within the population can impact the representativeness of the sample.
If the population is highly heterogeneous, it may be challenging to capture all its characteristics accurately.
Study Design and Execution:
The design and execution of the study, including survey questions, data collection methods, and potential confounding variables, can influence the outcomes and introduce biases.
While random sampling is a valuable tool, researchers must consider and address these factors and variables to enhance the representativeness and reliability of their study results. It is essential to employ rigorous methodologies and employ statistical techniques to account for potential biases and limitations.

you purchase a tight sealed container for your sugar cubes to keep the ants away. The container is a rectangular prism with dimensions 6 in by 4 in by 3. The sugar cubes have 0.5 in sides. Is your container big enough to store 560 sugar cubes?
The container is indeed big enough to store 560 sugar cubes.
To determine if the container is big enough to store 560 sugar cubes, we need to calculate the volume of the container and compare it to the total volume occupied by the sugar cubes.
The volume of a rectangular prism is given by the formula V = lwh, where l is the length, w is the width, and h is the height.
In this case, the dimensions of the container are:
Length (l) = 6 inches
Width (w) = 4 inches
Height (h) = 3 inches
Using the formula, the volume of the container is calculated as follows:
V = 6 inches * 4 inches * 3 inches
V = 72 cubic inches
Now, let's calculate the volume occupied by a single sugar cube:
The side length of a sugar cube is 0.5 inches, so the volume of a single sugar cube is:
V_cube = 0.5 inches * 0.5 inches * 0.5 inches
V_cube = 0.125 cubic inches
To determine the number of sugar cubes that can fit in the container, we divide the volume of the container by the volume of a single sugar cube:
Number of sugar cubes = V_container / V_cube
Number of sugar cubes = 72 cubic inches / 0.125 cubic inches
Number of sugar cubes = 576
Since the number of sugar cubes that can fit in the container is 576, which is greater than the required 560 sugar cubes, we can conclude that the container is indeed big enough to store 560 sugar cubes.
Therefore, the container can comfortably accommodate the desired quantity of sugar cubes while providing a tight seal to keep ants away.

C. 4.003 < 3.996
D. 0.541 > 0.145
E. 0.141 < 0.19
The true comparisons are:
B. 3.114 > 3.112: In this case, the number 3.114 is greater than 3.112, as the digit in the thousandth place (4) is greater than the corresponding digit in 3.112 (1).

Round your answer to the nearest tenth.
The length of the third side, which is opposite the angle of 84°, is approximately 30.1 units.
Given is a triangle with angles 64° and 32°, and side 21.1 and 30, we need to find the third side,
So, according to the angle sum property of triangle,
Third angle = 180° - (64° + 32°)
Third angle = 84°
To find the length of the third side, which is opposite the angle of 84°, we can use the Law of Sines.
The Law of Sines states that the ratio of the length of a side to the sine of its opposite angle is constant for all sides of a triangle.
Let's label the triangle with angles A, B, and C, and sides a, b, and c, respectively.
In this case, angle A is 84°, angle B is 64°, and angle C is 32°. Side a is the side opposite angle A, side b is the side opposite angle B, and side c is the side opposite angle C.
Using the Law of Sines, we have the following equation:
sin(A) / a = sin(B) / b = sin(C) / c
We want to find the length of side a, so we can rearrange the equation as follows:
sin(A) / a = sin(B) / b
Now we can substitute the given values:
sin(84°) / a = sin(64°) / 30
To find side a, we can solve for it algebraically:
a = (sin(84°) × 30) / sin(64°)
Calculating this expression, we get:
a ≈ 30.1
Therefore, the length of the third side, which is opposite the angle of 84°, is approximately 30.1 units.

Find a dimensionless product relating the torque, (ML²T-²) produced by an automobile engine, the engine's rotation rate, (T-¹), the volume V of air displaced by the engine, and the air density p.
The dimensionless product relating the torque, rotation rate, volume, and air density is:
Pi = (torque) * (rotation rate)² * (volume)^(1/3)
To find a dimensionless product relating the torque (ML²T⁻²) produced by an automobile engine, the engine's rotation rate (T⁻¹), the volume V of air displaced by the engine, and the air density p, we can make use of the Buckingham Pi theorem.
The Buckingham Pi theorem states that in a physical problem involving n variables with k fundamental dimensions, there will be n - k dimensionless quantities that can be formed as products of powers of the original variables.
In this case, we have 4 variables with 3 fundamental dimensions: torque (M L² T⁻²), rotation rate (T⁻¹), volume (L³), and air density (M L⁻³). Therefore, we expect to have 4 - 3 = 1 dimensionless product.
Let's define the dimensionless product (Pi) as:
Pi = (torque)ᵃ * (rotation rate)ᵇ * (volume)ᶜ * (air density)ᵈ
To determine the powers (a, b, c, d), we equate the dimensions on both sides of the equation:
M L² T⁻² = (M)ᵃ * (T⁻¹)ᵇ * (L³)ᶜ * (M L⁻³)ᵈ
Equating the dimensions of mass (M):
1 = a + d
Equating the dimensions of length (L):
2 = 3c - 3d
Equating the dimensions of time (T):
-2 = -b
Solving these equations, we find:
a = 1
b = 2
c = 1/3
d = 0
This dimensionless product captures the relationship between these variables, independent of their specific units and scaling factors.

A home decor store donated a percent of every sale to hospitals. The total sales were $8,400 so the store donated $672. What percent of $8,400 was donated to hospitals?
Answer:
8% of sales donated-----------------------
What percent of $8400 is $672?
672/8400 * 100% = 0.08 * 100% = 8%Answer:
8%
Step-by-step explanation:
To find the percentage that was donated to hospitals, we can set up the following equation:
[tex]\sf \dfrac{total\: donation}{ total \:sales} * 100 = percentage \:donated[/tex]
In this case, the total donation was $672 and the total sales were $8,400.
Substituting these values into the equation, we get:
[tex]\sf \dfrac{672}{8400} * 100 = percentage \:donated[/tex]
Simplifying this expression:
(0.08) * 100 = percentage donated
8% = percentage donated
Therefore, the home decor store donated 8% of $8,400 to hospitals.

5m is the height of a cone with a diameter of 12 m whose volume is 188 m³.
To find the height of a cone, we can use the formula for the volume of a cone and solve for the height.
The formula for the volume of a cone is:
V = (1/3)× π × r² × h
Given that the diameter of the cone is 12 m, the radius (r) is half of the diameter, which is 6 m.
We are also given that the volume of the cone is 188 m³.
Using the formula, we can rearrange it to solve for the height (h):
h = (3V) / (πr²)
Plugging in the values:
h = (3 × 188) / (3.14 × 6²)
h = 564 / (3.14 × 36)
h = 564 / 113.04
h =4.9916
h=5

The equation for the area of a trapezoid is A equals one-half times h times the quantity of b subscript 1 plus b subscript 2 end quantity.. If A = 28, b1 = 6, and b2 = 8, what is the height of the trapezoid?
h = 2
h = 4
h = 6
h = 7
Answer:
h = 4 units
Step-by-step explanation:
Given equation:
[tex]\text{A}_{\text{trapezoid} } = \dfrac{1}{2}(h)(b_{1} + b_2)[/tex]
Given numerical values:
A = 28b₁ = 6b₂ = 8Plug in all values into the equation and simplify it to find the height:
[tex]\implies \text{28} = \dfrac{1}{2}(h)(6 + 8)[/tex]
[tex]\implies\text{28} = (h)(3 + 4) = 7h[/tex]
[tex]\implies h = \dfrac{28}{7} = 4[/tex]
Therefore, the measure of the height is 4 units.

In a group of 150 kids 6 have green eyes 52% have brown eyes 16% have gray eyes and the rest have blue eyes what percentage of the kids have blue eyes.
Answer:
[tex]\boxed{\boxed{\sf{\:\:\: \green{Percentage = 28\%}\:\:\: }}}[/tex][tex]\\[/tex]
Step-by-step explanation:
We know that the total number of kids is 150. We can find the number of kids with green, brown, and gray eyes using the given percentages:
[tex]\sf\dashrightarrow Green\: eyes = 6\: kids[/tex]
[tex]\sf\dashrightarrow Brown\: eyes = 0.52 \times 150 = 78\: kids[/tex]
[tex]\sf\dashrightarrow Gray\: eyes = 0.16 \times 150 = 24\: kids[/tex]
[tex]\\[/tex]
To find the number of kids with blue eyes, we can subtract the number of kids with green, brown, and gray eyes from the total number of kids:
[tex]\sf\dashrightarrow Blue\: eyes = 150 - 6 - 78 - 24[/tex]
[tex]\sf\dashrightarrow Blue\: eyes = 42\: kids[/tex]
[tex]\\[/tex]
Finally, we can calculate the percentage of kids with blue eyes by dividing the number of kids with blue eyes by the total number of kids and multiplying by 100:
[tex]\sf\implies Percentage = \dfrac{42}{150} \times 100[/tex]
[tex]\sf\implies Percentage = \dfrac{4,200}{150}[/tex]
[tex]\sf\implies Percentage = \green{28\%}[/tex]
[tex]\\[/tex]
[tex]\\[/tex]
Therefore, 28% of the kids have blue eyes.

Find the equation of the line.
Use exact numbers
Answer:
y = [tex]\frac{2}{3}[/tex] x + 4
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 6, 0) and (x₂, y₂ ) = (0, 4) ← 2 points on the line
m = [tex]\frac{4-0}{0-(-6)}[/tex] = [tex]\frac{4}{0+6}[/tex] = [tex]\frac{4}{6}[/tex] = [tex]\frac{2}{3}[/tex]
the line crosses the y- axis at (0, 4 ) ⇒ c = 4
y = [tex]\frac{2}{3}[/tex] x + 4 ← equation of line
