Micah wants to know the most common style of surfboard used at Breakers Point. He surveys surfers at Breakers Point between 8:00 A.M. and 12 P.M. Which of the following statements is true about Micah’s survey? Select all that apply.
A. Micah will obtain a random sample by talking to as many surfers as possible.
B. The population for the survey is all people who surf at Breakers Point.
C. Micah will not get a representative sample.
D. Micah's sample will be representative because anyone can surf at Breakers Point
Answer: B I think I hope it helps
Step-by-step explanation:
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.What is random sampling?It is a method of selecting a set number of essential items from a given population.
Each item has an equal likelihood of getting chosen.
A. Micah will interview as many surfers as possible to obtain a random sample.
This statement is not always true because Micah may not be able to speak with all of the surfers at Breakers Point during the time frame specified. Also, randomly selecting surfers would result in a more accurate picture of the population.
B. The survey's population consists of all Breakers Point surfers.
This remark is correct, as the demographic of interest at Breakers Point is surfers.
C. Micah will not be able to obtain a representative sample.
This assertion is also correct, as the poll is only done between 8:00 a.m. and 12:00 p.m., which may not be representative of all Breakers Point surfers.
Furthermore, if Micah only polls surfers in a specific place or time period, the sample may be biased.
D. The statement is not always true because not all surfers surf at the same time or location, or have the same level of experience or surfboard preference.

can someone please explain
how to do this
Answer:
93
Step-by-step explanation:
A + B +C = 180
75+51 + C =180
126 +C =180
C = 180-126 = 54
DCB : ACD = 2:1
DCB = 2x
ACD = x
2x+x=54
3x = 54 ; x = 54/3 = 18
DCB = 2x = 2 x 18 = 36
dcb + dbc + bdc = 180
51 + 36 + bdc = 180
87 + bdc = 180 ; bdc = 180 - 87 = 93
I hope im right!!
Answer:
the answer is 93°
Step-by-step explanation:
As you know that in a triangle,
angle1+angle2+angle3 = 180°
hence,
angle ABC + angle BAC + angle DCB + angle ACD ( Angle DCB + angle ACD = angle BCA) = 180°
75°+51°+2x+1x (let the ratio be x) = 180°
126°+3x = 180°
3x = 54°
x = 18°
2x = 36° = angle DCB
In triangle DCB,
51°+36°+angle BCD = 180°
angle BCD = 180°- 87°
Hence, angle BCD = 93°

A number is 12 more than the other. Find the numbers if their sum is 48
Answer:
let one number be x and the other be x + 12
sum = 48
x + x + 12 = 48
2x + 12 = 48
2x = 48 - 12
2x = 36
x = 36 by 2
x = 18
therefore x = 18 and x+12= 18+12=30
so the answer is 18 and 30

The total interest on a 5 year 5.2% loan with a principal of $10,000 is 10,000 × 0.052 × 5 = $2,600.
True or False?
Answer:
True
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5.2%/100 = 0.052 per year,
then, solving our equation
I = 10000 × 0.052 × 5 = 2600
I = $ 2,600.00
The simple interest accumulated
on a principal of $ 10,000.00
at a rate of 5.2% per year
for 5 years is $ 2,600.00.

Kiera randomly selected 35% of the eighth grade students in her school and asked them their favorite food in the cafeteria. Of the students surveyed, 60 chose chicken nuggets as their favorite food. Based on her school who would choose chicken nuggets as their favorite food served in the cafeteria?
Answer:
171
Step-by-step explanation:
Percentage randomly selected = 35%
Number of surveyed who chose chicken nugget = 60
To obtain the number who chose chicken nugget based on her school :
number who chose chicken nugget / Percentage randomly surveyed
60 ÷ 35%
60 ÷ 0.35
= 171.42
Approximately 171 students

Answer:
x=5.09
Step-by-step explanation:
Always look at what info they give you, here you have angle, opposite, and adjacent. The trig function that uses [tex]\frac{opp}{adj}[/tex] is tangent so tan (27) = [tex]\frac{x}{10}[/tex] so
x = 10 tan (27) so x = 10 (.5095254495) [make sure you are in degree mode] so x has to be 5.09

Write a System of Equations to solve the following problem:
The school that Maria goes to is selling tickets to the annual talent show. On the first day of ticket sales the school sold 1 senior citizen ticket and 12 student tickets for a total of $51. The school took in $93 on the second day by selling 5 senior citizen tickets and 6 student tickets. What is the price each of one senior citizen ticket and one student ticket?
Cost of Senior Citizen Ticket: $
Cost of Student Ticket: $
Answer:
Cost of Senior Citizen Ticket: $15
Cost of Student Ticket: $3
Step-by-step explanation:
Let the price of a senior citizen ticket be s.
Let the price of a student ticket be t.
Day 1:
s + 12t = 51
Day 2:
5s + 6t = 93
The system of equations is:
s + 12t = 51
5s + 6t = 93
Let's use the substitution method to solve it. Solve the first equation for s.
s = 51 - 12t
Now substitute s in the second equation with 51 - 12t.
5s + 6t = 93
5(51 - 12t) + 6t = 93
255 - 60t + 6t = 93
Subtract 255 from both sides. Combine -60t and 6t.
-54t = -162
Divide both sides by -54.
t = 3
Now substitute 3 for t in the equation
s = 51 - 12t
s = 51 - 12(3)
s = 51 - 36
s = 15
