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

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

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
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.

PLEASE HELP!! Urgent! :((
Answer:
the angle is 245°
Step-by-step explanation:
that is a pentagon, (a shape with 5 sides)
we know 4 of the angles in the pentagon
the sum of those 4 angles is
58°+100°+112°+25°=295°
to find a shapes total amount of °, the equation is (n-2)x180°
(5-2)x180°
=540°
540°-295°=245°
x=245°

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

Write an equation to find the total number of hours h the instructor exercises in any number of weeks w
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)
