When you talk about balanced equations you are talking about chemistry.
Chemical equation balance is to make sure that there are the same number of atoms of a given element in the right side than in the left side.
It is a chemical principle, the atoms do not create or destroy in a chemical reaction, then you have to count the same number of every kind of atoms in the left side than in the right side.
For example:H2 + O2 -> H2O is not balanced because there two atoms of oxygen in the left side and 1 atom of oxygen in the right side.
To balance this equation you have to insert coefficients:
2H2 + O2 -> 2H2O. Now you have 4 atoms of hydrogen in each side, and 2 atoms of oxygen in each side, making sure that none atoms was created or destroyed in the reaction.
there are 8 numbers and you want to get either a 3 or an 8
3 or 8 is 2 numbers out of the 8
so you have a 2/8 reduced to a 1/4 probability of getting them.
Answer for 1 is 22 degrees
Answer: Slope = -2.667/2.000 = -1.333
x-intercept = 5/4 = 1.25000
y-intercept = 5/3 = 1.66667
Step-by-step explanation: Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 1.667 and for x=2.000, the value of y is -1.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -1.000 - 1.667 = -2.667 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Answer:
Pretty sure that it is False
Step-by-step explanation:
Sampling variation, random samples dont really reflect the population from where i is drawn, but it is close.
