Noah wants to predict who will be selected as the sixth-grade treasurer for student council. Which of the following groups should Noah survey to make his prediction?A) The first 100 students from an alphabetical list of the entire school
B) The first 100 students from an alphabetical list of sixth graders
C) One hundred random students from the entire school
D) One hundred random students from the sixth grade

Answers

Answer 1
Answer:

One hundred randomstudents from the sixth grade. Therefore, option D is the correct answer.

What is random sampling?

In statistics, a simple random sample is a subset of individuals chosen from a larger set in which a subset of individuals are chosen randomly, all with the same probability. It is a process of selecting a sample in a random way.

First off, the survey should be focused on the sixth graders, since they are the demographic that will be voting for 6th grade treasurer.

Next, the group should be random, because random groups better represent the entire class than an alphabetic list. Maybe those first 100 kids in the list like Noah because he has a last name that begins with A or something. It's not likely, but it's something that could corrupt the data collection.

Therefore, option D is the correct answer.

Harold brought three pounds of red apples and 4.2 pounds of green apples from the grocery store we're both kinds of apples are $1.75 a pound how much did Harold spend on apples

Answers

So you multiply because you want to find out the cost of the total amount of apples per pound bought. You multiply 3 and 1.75 and you should get $5.25 for red apples. You multiply 4.2 pounds and 1.75 and you should get $7.35 for green apples.

Jerry has 7 3/4 dozen donuts. He purchased another 4.25 dozen donuts. How many dozens of donuts does he have now?

Answers

Answer:

12 dozens of donuts

Step-by-step explanation:

First, you want to change the decimal into a fraction. The decimal, 4.25, is the same as 4 25/100. You can reduce 4 25/100 to 4 1/4 by diving both the numerator and denomiator by 25.  Now that both of our numbers are fractins, we can just add the fractions up. 7 3/4 + 4 1/4 = 11 4/4 = 12\

Jerry got 12 dozens of donuts.

Answer:

12 dozen

Step-by-step explanation:

  • Relatively easy stuff, just recall fractions
  • A dozen means  12
  • he has 7 dozen (7 x 12=84) and 3/4 dozen (3/4 x 12=9) so that's 84+9= 93 donuts
  • he gets 4.25, which is the same as 4 1/4, so its 4 dozen (4 x 12=48) and 1/4 dozen (1/4 x 12=3) so that's 48+3= 51 donuts
  • Add what you got 93 + 51 = 144 donuts
  • Then divide this by 12 to get the number of dozens
  • 144/12 = 12 dozen

HELP PLEASEDory and Nemo go to Taco Bell for lunch. Dory orders three soft tacos and three double deckers for $11.25. Nemo pays $10.00 for four soft tacos and two Double Deckers. Write a system of equations that represents the lunch orders for Dory and Nemo. Use x to represent soft tacos and y to represent Double Deckers.

Answers

x = soft tacos
y = double deckers

Dory:
3x + 3y = 11.25 

Nemo:
4x + 2y = 10.00

---Now to solve for x and y---
---We find LCM of either x or y then make them cancel each other---
Dory multiply by 2:
6x + 6y = 22.50

Nemo multiply by 3:
12x + 6y = 30.00

--eliminate y--- 
Nemo subtract Dory:
6x = 7.50
Therefore x = 7.50 ÷ 6 = 1.25
---Now substitute x = 1.25 in either equation.---

Dory:
3.75 + 3y = 11.25
Therefore 3y = 11.25 - 3.75
therefore 3y = 7.50
there fore y = 2.50

y = 2.50 , x = 1.25

Sorry, that this is so long, I hope you understand. This is called simultaneous equations, you can read up on it.

Answer:

Dory: 3x+3y=11.25

Nemo: 4x+2y=10.00
