The statements that are true are:
The population for the survey is all people who surf at Breakers Point.
Micah will not get a representative sample.
Options B and C are the correct answer.
What is random sampling?It is the way of choosing a number of required items from a population given.
Each item has an equal probability of being chosen.
We have,
A.
Micah will obtain a random sample by talking to as many surfers as possible.
This statement is not necessarily true as Micah may not be able to talk to all the surfers at Breakers Point during the time frame mentioned. Additionally,
Randomly selecting surfers would result in a better representation of the population.
B.
The population for the survey is all people who surf at Breakers Point.
This statement is true, as the population of interest is the surfers at Breakers Point.
C.
Micah will not get a representative sample.
This statement is also true, as the survey is conducted only between 8:00 A.M. and 12 P.M, which may not be representative of all surfers at Breakers Point.
Additionally, there may be bias in the sample if Micah only surveys surfers at a certain location or time period.
D.
Micah's sample will be representative because anyone can surf at Breakers Point.
This statement is not necessarily true as not all surfers may surf at the same time or location, or have the same level of experience or preference for surfboard style.
Thus,
The population for the survey is all people who surf at Breakers Point and
Micah will not get representative sample statements are true.

A frame is 1 in wide and 4 in tall. If it is enlarged to a height of 20 in, then how wide will it be
A ratio shows us the number of times a number contains another number. The width of the frame after enlargement is 5 inches.
What is a Ratio?A ratio shows us the number of times a number contains another number.
Given that the frame is 1 inch wide and 4 inches tall. Now, if the frame is enlarged, then the ratio of the corresponding sides will be equal.
Further, given that height after enlargement is 20 inches. Therefore, if the ratio of the height of the before enlargement and after enlargement is taken, then it will be,
Ratio = After Enlargement/ Before Enlargement
Ratio = 20 inches / 4 inches
Ratio = 5
Now, if we use the ratio to find the width of the frame after enlargement, then the frame width will be,
Ratio = After Enlargement/ Before Enlargement
5 = Width after Enlargement/ Width before Enlargement
5 = Width after Enlargement/ 1 inche
Width after Enlargement = 5 inches
Hence, the width of the frame after enlargement is 5 inches.

Answer:
[tex] y = \dfrac{w}{h - 5t^2} [/tex]
Step-by-step explanation:
w = yh − 5yt^2
There is a y in each term on the right side. We factor it out.
w = y(h - 5t^2)
Now we divide both sides by h - 5t^2 to isolate y.
[tex] \dfrac{w}{h - 5t^2} = y [/tex]
