Answer: your independent variable will be the group that receives the placebo. the dependent variable would be the group that received serum B, and your experimental group are the agents from both groups. I say that because both groups received the experimental serum, whereas the first group got a placebo. not sure if your teacher only wants one answer for each questions, but this is what I believe to be correct.

Answer:
1, 210.
2. 72 minutes.
3. 42 minutes
4. 2 inches.
5. 3 cents.
Step-by-step explanation:
1. First, divide 240 by 8, which will get you 30, now multiply 30 by 7 and you will get 210 which is your answer.
2. Your keyword here is times. So you know you will multiply. So just multiply 8 and 9, and your product is 72, so 72 minutes.
3. Multiply 3 1/2 by 12, or convert your fraction to a decimal, which in decimal form is 3.50. Your product would be 42.
4. Multiply 1/7 by 14, you should get 14/7, which is an improper fraction. Divide 14 by 7 and you will get 2 inches.
5. So here you have to find the unit rate. Divide the price by the quantity.
4.86/16.2=0.297530865
Round the number up, which would be 3. So it would be 3 cents
Hope this helps :)
Review the table.
A 2-column table with 4 rows. Column 1 is labeled x with entries pi, StartFraction 7 pi Over 6 EndFraction, StartFraction 5 pi Over 4 EndFraction, StartFraction 4 pi Over 3 EndFraction. Column 2 is labeled y = sine (x) with entries 0, blank, blank, blank.
Which values, in order, will complete the table?
Answers
Answer:
I think that the answer is A.
Step-by-step explanation:
The values that complete the table are -1/2, -√2/2 and -√3/2
How to complete the table of values?The function is given as:
[tex]y = sin(x)[/tex]
From the table, we have:
sin(π) = 0
Next, we calculate the value of y for other values of x
When x = 7π/6, we have:
sin(7π/6) = -1/2
When x = 5π/4, we have:
sin(7π/6) = -√2/2
When x = 4π/3, we have:
sin(4π/3) = -√3/2
Hence, the values that complete the table are -1/2, -√2/2 and -√3/2

y=112
y+(4x-2)+30=180

-140 to both sides
4x=180
divide by 4 to both sides

Hello!!! Princess Sakura here ^^
Step-by-step explanation:
The first step you should take is to distribute the 2, so if you do that it'll leave you with... [tex]12=-4v+2v+4[/tex]
Then you notice the like terms and then you have to combine them and that'll give you... [tex]12=-2v+4[/tex]
Now you subtract the 4 to both sides and get... [tex]8=-2v[/tex]
Lastly the fun step is to divide the -2 to both sides and to get the answer of...
[tex]v=-4[/tex]
