Krista says that her chickens lay the most eggs of any chickens in the county. To prove her daim, she could survey chicken farms to see how many eggs each of their chickens laid that day. In this scenario, what is the population and what is a possible representative sample?
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Population refers to the all elements which belongs to a particular subject of interest. In the scenario above, Since Krista is comparing eggs laid by any chicken in the county, then the population will be all chickens in the county.
A representative sample, which is a random subset of the population could be a certain number of chickens drawn from different poultry farms around the county. If selected randomly, will be representive of the chickens in the county.
Answer: Look at the expanation please.
Step-by-step explanation:
So she needs to know the population. So the population would be all of the chicken farms or chickens that are in her county.
The next question is what is a possible representative sample?
So one of the possibility is would be choosing a random farm in Krista´s county.
But there are many possible representative samples. You can get creative.
Thank you hope this helps. :)

Diane has a rope that is 8 meters long. She cuts away a piece that is 1.67 meters long. How long is the remaining piece of rope?
Answers
Answer:
6.33 m
Step-by-step explanation:
Total length of the rope = 8 m
Cut length of the rope = 1.67 m
We need to find the remaining piece of the rope.
Remaining piece = Total length - cur length
= 8 m - 1.67 m
= 6.33 m
So, 6.33 m is the remaining piece of the rope.

Two cylinders are similar. Find the surface area of the smaller cylinder small cylinder height is 3 the larger cylinder height is 5 and the surface area is 236 what is the surface area of the smaller cylinder
Answers
Answer:
141.6
Step-by-step explanation:
Two cylinders are similar. Find the surface area of the smaller cylinder small cylinder height is 3 the larger cylinder height is 5 and the surface area is 236 what is the surface area of the smaller cylinder
We solve using Proportion
Height/ Area
Height of small cylinder / Area of small cylinder = Height of large cylinder / Area of large cylinder
= 3/x = 5/236
Cross Multiply
5x = 3 × 236
x = 3 × 236/5
x = 141.6
Please help me with the question please ASAP ASAP I’m begging please
Answers
Answer: a= 144. b= 67
Step-by-step explanation:
Angle b and the angle of measure 113 are same side interior angles which sum to 180 (When 2 parallel lines are cut by a transversal, special angles are formed)
113+b=180. Subtract 113 from both sides.
b= 67 degrees
Now that you have b, the interior angles of four sided figures sum to 360.
a+113+67+36=360. Combine like terms.
a+216=360. Subtract 216 from both sides.
a= 144 degrees

Solve the equation for the value of the variable. 24 = 6m
Answers
Answer:
4
Step-by-step explanation:
24 = 6m
24 / 6 = 6 / 6 m
4 = m
The required solution to the given equation is m = 4 for the variable m.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The equation is given in the question, as follows:
24 = 6m
We have to solve the equation for the value of the variable.
As per the question, we have
⇒ 24 = 6m
Divided by 6 into both sides of the above equation, and solve for the value of the variable m,
⇒ 24 / 6 = 6m / 6
⇒ 4 = m
⇒ m = 4
Thus, the required solution to the given equation is m = 4.
