A study with a sample that is very different from the population is biased
What is Population Density?The population density, or the number of people divided by the area's size, is determined by the number of people who reside there. Numerous creatures' distribution, growth, and migration can all be explained by population density.
Population density = number of people / the area they occupy
Given data ,
A study with a sample that is very different from the population is J. biased.
In statistical terms, bias refers to any systematic error or deviation from the true value that can occur in a study. When a study is biased, the results may not be representative of the population and may not be generalized other settings.
Results from a research may be skewed if the sample chosen is considerably different from the population. Both experimental and observational research may experience this. As a result, alternatives F and G do not offer sufficient details to assess the study's objectivity.

The mean age of 11 women in an office is 31 years old.
The mean age of 6 men in an office is 29 years old.
What is the mean age (nearest year) of all the people in the office?
Answer: 30.2
Explanation:
The mean is calculated by taking the sum of the values and dividing by the count.
For instance, for the 6 women, with the mean being 31, we can see that the ages summed to 186:
186
6
=
31
And we can do the same for the men:
116
4
=
29
And now we can combine the sum and count of the men and women to find the mean for the office:
186
+
116
10
=
302
10
=
30.2
Step-by-step explanation:
9514 1404 393
Answer:
30
Step-by-step explanation:
The total of the ages of the 11 women is 11·31 = 341. The total of the ages of the 6 men is 6·29 = 174. Then the total of the ages of all 17 people in the office is ...
341 + 174 = 515
and their average age is ...
515/17 ≈ 30.294 ≈ 30
The mean age of the people in the office, to the nearest year, is 30.
_____
The mean is the total divided by the number of contributors. Then the total is the mean times the number of contributors.

Maria y juan deben realizar el mapamundi en medio pliego de cartulina para la tarea de sociales pero cada uno tiene un cuarto de cartulina maria le dice a su compañero que si unen los cuartos de cada uno obten dran el medio pliego que necesitan . Maria tine razon justifica tu rrespuesta
Answer:
Cuando María afirma que si unen sus dos cuartos de cartulina obtendrán el medio pliego que necesitan, esto es:
Verdadero.Step-by-step explanation:
Para entender mejor el ejercicio vamos a utilizar números cada vez que se habla de cantidades de cartulina, por lo tanto, María y Juan tienen 1/4 de cartulina cada uno, es decir, 1/4 * 2, y necesitan 1/2 pliego para poder realizar su tarea, por lo tanto, con la afirmación de María sobre unir los dos cuartos de cartulina, en caso de que sea verdadero, ocurrirá que la suma de los dos cuartos dará el medio pliego, como se muestra a continuación:
Total de cartulina de María y Juan = [tex]\frac{1}{4}+\frac{1}{4}[/tex]Total de cartulina de María y Juan = [tex]\frac{4+4}{16}[/tex]Total de cartulina de María y Juan = [tex]\frac{8}{16}[/tex]Procedemos a simplificar el fraccionario obtenido, sacando mitad tanto en el numerador como en el denominador:
Total de cartulina de María y Juan = [tex]\frac{4}{8}[/tex]Total de cartulina de María y Juan = [tex]\frac{2}{4}[/tex]Total de cartulina de María y Juan = [tex]\frac{1}{2}[/tex]Como puedes ver al final, la cantidad de cartulina de ambos, al ser sumada, da como resultado el 1/2 (medio) pliego que necesitan para su tarea de sociales, por lo cual la afirmación de María es correcta.

A moving truck is 16 feet long, 10 feet wide, and 8 feet high. If there are two boxes I. The truck that are each2 feet cubes, how much space remains in the truck?
Answer:
The space remaining in the truck is 1,276 cubic feet
Step-by-step explanation:
Given that the dimensions of the haul of the moving truck are;
The length of (the haul) of the moving truck = 16 feet
The width of (the haul) of the moving truck = 10 feet
The height of (the haul) of the moving truck = 8 feet
The number of boxes in the truck = 2 boxes
The dimensions of the boxes in the truck = 2 feet cubes
From the given dimensions, we have;
The volume of the boxes, [tex]V_{boxes}[/tex] = 2 ft.³ + 2 ft.³ = 4 ft.³
The volume of the haul, [tex]V_{haul}[/tex] = 16 feet × 10 feet × 8 feet = 1,280 ft.³
The amount (volume) of space remaining, V = [tex]V_{haul}[/tex] - [tex]V_{boxes}[/tex]
∴ V = 1,280 ft.³ - 4 ft.³ = 1,276 ft.³
The amount of space remaining, V = 1,276 ft.³
What are the coordinates of the vertex of y=x²+4x+3?
Answer:
(-2, -1).
Step-by-step explanation:
y = x² + 4x + 3
Completing the square:
y = (x + 4/2)^2 - (4/2)^2 + 3
y = (x + 2)^2 - 4 + 3
y = (x + 2)^2 - 1.
This is vertex form and the coordinates of the vertex are (-2, -1).
