A researcher is comparing the effectiveness of three devices designed to help people who snore. There are 120 people who snore participating in the experiment. Using a table of random digits, the researcher will randomly place the participants into three equally sized treatment groups suitable for comparison.
Which design is the most appropriate for this experiment?
A Randomly number each person with 1, 2, or 3. Assign the people labeled 1 to the device 1 group, the people labeled 2 to the device 2 group, and the people labeled 3 to the device 3 group.
B Number each participant from 1 to 120. Reading numbers from left to right from a random number table, identify 80 unique numbers from 1 to 120. Assign the people whose labels are the first 40 numbers to the device 1 group. Assign the people whose labels are the second 40 numbers to the device 2 group. Assign the remaining people to the device 3 group.
C Number each participant from 000 to 119. Reading numbers from left to right on a random number table and looking at three digits at a time, identify 80 unique three-digit numbers from 000 to 119. Assign the people whose labels are the first 40 numbers to the device 1 group. Assign the people whose labels are the second 40 numbers to the device 2 group. Assign the remaining people to the device 3 group.
D Select a participant, and identify the first digit reading numbers from left to right on a random number table. If the first digit is a 1, 2, or 3, assign the participant to the device 1 group. If the first digit is a 4, 5, or 6, assign the participant to the device 2 group. If the first digit is a 7, 8, or 9, assign the participant to the device 3 group. If the first digit is a 0, skip that digit and move to the next one to assign the participant to a group. Repeat this process for each participant.

A line that is not parallel nor perpendicular to y=2/4x+1
Answer:
y=2x+1
Step-by-step explanation:
Parallel = gradients are the same
Example: y=2/4x+5
Perpendicular = gradients are the inverse of each other
Example: y= -4/2x+1
Any equation would be correct unless the gradient is 2/4 or -4/2

if the standard deviation of the data values in a sample is 16, what is the variance of the data values?
A. 289
B. 225
C. 256
D. 196
Answer:
C. 256Step-by-step explanation:
Variance is the square of the standard deviation:
υ = σ²υ = 16² = 256Correct choice is C
Answer:
.
standard variance=standard deviation²
standard varience =16²
standard varience=16²=256 is your answer
The total length of a road trip was 19.6 hours. If highway signs are posted every 0.7 hours, including one at the end of the road trip, how many highway signs will there be on the road trip.
Answer:
28
we can do it by dividing the journey time by in how after how many time the sign is place so 19.6/0.7=28
Hope you like it please make me the brainiest.

it took Stephanie 2 1/3 hours to travel to her Aunt's house, and then 1 2/3 hours to travel to her Grandma's house. How many total hours did Stephanie travel?
Answer:
It took Stephanie 4 hours
Step-by-step explanation:
2 1/3 + 1 2/3 = ?
To make it easier, let's add them differently
2 + 1 = 3
1/3 + 2/3 = 1
1 + 3 = 4 hours
Or turn them into mixed numbers:
7/3 + 5/3 = 12/3 = 4 hours
So our final answer is 4 hours.
Hopefully this helps :3 sorry if wrong :( Plz mark brainiest if correct :D Your bootiful/handsome! Have a great day luv <3

Apply the distributive property. Then simplify by combining like terms. How do you do that? 14(-7w-4)
Answer:
-98w-56
Step-by-step explanation:
Distributive property means to take the 14 and distribute and multiply by everything inside the parenthesis,
so 14(-7w) -4(14) = -98w-56
Since there are not 'like terms' you are done

First, rewrite 1/9 and 2/15 so that they have a common denominator. Then use to order 1/9 and 2/15.
Answer: 1/9= 5/45 or 2/15= 6/45
Step-by-step explanation:
1/9 *5/5 = 5/45
1*5 =5 (numerator)
9*5=45 (denominator)
-----------------------------------------------------------------------------------
2/15 *3/3 = 6/45
2*3= 6 (numerator)
15*3= 45 (denominator)
