B) inferential
C) analogical
D) descriptive

Answers

Answer 1

Answer:

Answer: Option (D) is the correct answer.

Step-by-step explanation:

A data that describes or tells what it is about or what is shows is known as descriptive statistic.

A descriptive statistic helps in summarizing a set of data which can be representation of the entire or sample of a population.

It basically provides a meaning to the information described by the data.

Thus, we can conclude that a statistic that describes a sampled group is called descriptive.

Answer 2

Answer: Descriptive statistic analyze and summarize the data into a meaningful form so A statistic that describes a sampled group is called descriptive
so option D is correct from above all
hope it helps

How many batting lineups are there for nine players of a baseball team if the center fielder must bat fourth, the second baseman must bat third and the pitcher last?

Answers

The number of possible batting lineups is 720

Explanation

Total number of players in the team = 9

The center fielder must bat fourth, the second baseman must bat third and the pitcher last. That means, 3 slots in the batting line-up are already assigned to 3 players.

So, the remaining (9 - 3) = 6 players will be assigned to remaining 6 slots.

Thus, the possible number of ways so that 6 players can be assigned to 6 slots will be: $6! = 6*5*4*3*2*1=720$

A researcher wants to develop a product for families who have small children. He needs to determine if there is a nationwide interest in a toy that will help children describe their emotions. He asks only a sample of the population to complete his survey. What should be true of the sample so that the results of the survey can be used to predict the results of surveying the population?A) The size of the sample should be the same size as the population.
B)The families included in the sample should represent the families in the population.
C) The families included in the sample cannot be included in the population.
D)The size of the sample should be larger than the size of the population.

Answers

Here is the answer to the given question above. Given the scenario, that statement that is considered true of the sample so that the results of the survey can be used to predict the results of surveying the population is this: The families included in the sample should represent the families in the population. The answer would be option B.

Answer:

The answer is B.

A city map is placed on a coordinate grid. The post office is located at the pointP ( 5, 35) , the library is located at the point L (15, 10) , and the fire station is
located at the point F  (9, 25) . What is the ratio of the length of PF to the length of
LF ?
A 2 : 3
B 3 : 2
C 2 : 5
D 3 : 5

Answers

The distance between two points:
$d=√((x_2-x_1)^2+(y_2-y_1)^2)$
(x₁,y₁), (x₂,y₂) - the coordinates of the points

$P(5,35) \nL(15,10) \nF(9,25) \n \n\overline{PF} = √((9-5)^2+(25-35)^2)=√(4^2+(-10)^2)=√(16+100)= \n=√(116)=√(4 * 29)=2√(29) \n \n\overline{LF}=√((9-15)^2+(25-10)^2)=√((-6)^2+15^2)=√(36+225)= \n=√(261)=√(9 * 29)=3√(29) \n \n\frac{\overline{PF}}{\overline{LF}}=(2√(29))/(3√(29))=(2)/(3)=2:3$

The answer is A.

Final answer:

The ratio of the length of PF to the length of LF on the coordinate grid can be found by using the distance formula. After calculation, we find that the ratio is approximately 2:3.

Explanation:

To answer this question, you need to know how to calculate the distance between two points on the coordinate grid, which can be found using the distance formula. The distance formula is √[(x2-x1)² + (y2-y1)²] where (x1, y1) and (x2, y2) are the coordinates of two points on a plane.

First, calculate the length of PF as follows:

PF = √[(9-5)² + (25-35)²] = √[16 + 100] = √116≈10.77

Next, calculate the length of LF as follows:

LF = √[(15-9)² + (10-25)²] = √[36 + 225] = √261≈16.155

Hence, the ratio of the length of PF to the length of LF is approximately 10.77:16.155 which approximately reduces to 2:3.

Therefore, the answer is A: 2:3.

"What temperatures are included in the temperature danger zone? A) 0°F (-18°C) to 41°F (5°C) B) 32°F (0°C) to 100°F (38°C) C) 41°F (5°C) to 140°F (60°C) D) 141°F (61°C) to 240°F (116°C)."

Answers

Answer:

C) 41°F (5°C) to 140°F (60°C) D) 141°F

Step-by-step explanation:

The temperature danger zone refers to the range of temperatures at which bacteria can grow and multiply rapidly in food, increasing the risk of foodborne illness. It is important to understand this zone to ensure proper food safety practices.

In the temperature danger zone, which spans from 41°F (5°C) to 140°F (60°C), bacteria can multiply rapidly in food, potentially leading to food poisoning if consumed. Temperatures within this range provide an optimal environment for bacterial growth, as they promote the reproduction of microorganisms that can cause foodborne illnesses.

It is important to note that food should not be kept in the temperature danger zone for an extended period of time. To prevent the growth of harmful bacteria, perishable foods should be stored below 41°F (5°C) or above 140°F (60°C). Keeping food within these safe temperature ranges helps to reduce the risk of foodborne illnesses and ensures the safety of the food we consume.

In summary, the temperature danger zone includes temperatures between 41°F (5°C) and 140°F (60°C), and it is crucial to adhere to proper food safety practices to prevent the growth of harmful bacteria and reduce the risk of foodborne illnesses.

Final answer:

The temperature danger zone, important in food safety, falls between 41°F (5°C) and 140°F (60°C). It's key to avoid keeping food in this range to prevent bacterial growth and potential foodborne illnesses.

Explanation:

In the context of food safety, the temperature danger zone is the temperature range in which foodborne bacteria can grow. This zone is typically defined as being between 41°F (5°C) to 140°F (60°C). Therefore, option C is correct. It's very important to keep food out of this range to prevent foodborne illnesses. When food is kept at a temperature inside this danger zone, pathogens can multiply quickly, especially if conditions last longer than two hours.
