Which is the best place to find a representative sample for a survey on the most popular extracurricular activity at a high school?
a. high school wrestling match
b. high school basketball game
c. high school chorus
d. high school cafeteria
Answers
Answer:
A cafeteria because all of the other choices would be biased towards the sport/activity that is already occurring.
Step-by-step explanation:
During a wrestling match, people are definitely going to be directed towards wrestling. During a basketball game, people prefer basketball. During a chorus or choir, people prefer choir most likely.
When in a cafeteria, people just sit there and eat or play games or talk.
People are also stationary so people won't be yelling at you to back off when you jump in the stadium for wrestling/basketball and start blasting questions at someone in a headlock.

A teacher buys some pencils.
• He buys 2 pencils for each of his students.
• He buys 10 additional pencils.
• Each pencil costs $0.10.
Which equation describes the total amount of money
(y), in dollars, that the teacher spends on pencils as a
function of the number of students (x) he has?
Answers
Answer:
y=2x(.10)
Step-by-step explanation:
I think this is correct but it is 0.10 times 2 because it is 2 pencils/student and each pencil cost 10 cents. We multiply by x because we need to have 2 for each student

And a
Jayden has x nickels and y pennies. He has at most 14 coins worth no less than $0.34 combined. Solve this system of inequalities graphically and determine one possible solution.
Answers
Answer:
Step-by-step explanation:
Number of nickels with Jayden = x
Number of pennies with Jayden = y
Since, number of coins is at most 14,
x + y ≤ 14 -------(1)
Worth of nickels = $0.05x
Worth of pennies = $0.01y
Since, worth of pennies is not less than $0.34,
0.05x + 0.01y ≥ 0.34
5x + y ≥ 34 --------(2)
By using a graphing calculator,
Common point of of both the inequalities is (5, 9)
Therefore, Number of nickels = 5
Number of pennies = 9

The following cone has a height of 4 inches and a volume of 12π. What is the radius of the cone? Enter your answer as the correct value, rounded to the nearest tenth if necessary.
Answers
Answer:
R= 1.69
Step-by-step explanation:
For this, you just have to remember that the volume of a cone is 1/3hπr² (1/3 times pi times the radius squared). Our volume is 12π, so we plug in 12π into our formula, as well as our height of 4 inches, to solve for the radius, like so:
12π=(1/3)(4)πr²
Now we just do the rest of the math.
12π=(1/3)(4)πr²
12=(1/3)(4)r² (divide both sides by π)
3=1/3r² (divide both sides by 4)
9=r² (divide both sides by 1/3)
3=r (take the square root of both sides).
Therefore, the radius of the cone is 3.
Solve 2x + 5 = 12 please

Answer:
D. 50
Step-by-step explanation:
∠CGF and ∠AFG add up 180° because they are same side interior angles. We can write an equation to model the situation:
m∠CGF + m∠AFG = 180°
And, we can substitute:
3x - 20 + x = 180
4x - 20 = 180
4x = 200
x = 50

4x-2y=14
y=1/2x-1
Answers
Since why equals 1/2x-1 you
Do 2(1/2x-1)= x-2
You multiple by 2 cause there’s two on the top for y. So the problem is now 4x-x-2
Combine like terms 3x+2=14
Subtract two on both sides
3x=12
X=4
Go back to the bottom since u know x now do y= 4.1/2-1 solve to get one
Y=1 so your answer is (4,1)
Leila is at a charity fundraiser and has a chance of receiving a gift 6/17 . The odds in favor of receiving a gift are . Find the probability of Leila receiving a gift.
Answers
Answer:
6 / 23
Step-by-step explanation:
The question is not correct, the correct question is:
Leila is at a charity fundraiser and has a chance of receiving a gift. The odds in favor of receiving a gift are 6:17. Find the probability of Leila receiving a gift.
Solution:
Odds provide a measure of the likelihood of a particular outcome occurring. Odds is the ratio of the number of events that produce that outcome to the number that do not.
The probability of an event occurring is the ratio of number of favorable outcomes to the total number of outcomes possible.
Given that the odds in favor of receiving a gift are 6:17. Therefore:
number of favorable outcome = 6, number of unfavorable outcome = 17
Total number of possible outcomes = 6 + 17 = 23
The probability of Leila receiving a gift = number of favorable outcome / Total number of possible outcomes = 6 / 23
The probability of Leila receiving a gift = 6 / 23
