x 6
six is your base number.. then you do 6x8 which is 48 you will leave the 8 under the ones column and carry the 4 above the seven then you do 7x6 plus the 4.
I think that's how i learned it

Answer:
Step-by-step explanation:
Upper box in the diamond: Add the two numbers ⇒ (-2) + 3 = -1
Bottom box in the diamond : Multiply the two numbers ⇒ (-2) * 3 = -6
3) Upper box = (-6) + (-3) = (-9)
Bottom box = (-6) *(-3) = 18
4) Upper box = 1 +(-11) = -10
Bottom box = 1 *(-11) = -11
5) Upper box = 7+8 = 15
Bottom box = 7*8 = 56
divide 2 b 3
2 divided by 3 = 0.625
move decimal point 2 places to the right to turn to a percentage
0.625 = 62.5%
F(-3.29) = (-3.29) + 2.58
f(-3.29) = -0.71
Answer:
Is an experimental study
Step-by-step explanation:
In an observational study you don't control any aspect of the investigation you just observe the variables that you determined since the beginning without any intervention.
In this case you are controlling who sees one or the other video, then you are controlling one of the variables that is the type of video each group sees and because of this it is an experimental study. Researchers designed an experiment to prove the null hypothesis they had.
