1.2 * 10^-5 * 1.5 * 10^-4
= 1.2 * 1.5 * 10^-5 * 10^-4
= 1.8 * 10^-9
Its A
Answer:
The completed reaction is
CaCO3 + 2 HCl → (Ca+2 + 2 Cl-)aq + H2O + CO2↑
The second equation because they all have a common factor of 3. You can get x by itself. However, with the first one, you'll end up with fractions instead.
Answer:
The answer is Discrete Random Variable
Step-by-step explanation:
A random variable is considered discrete if its possible values are countable.
In our case,
In a basketball game, for example, it is only possible for a team's score to be a whole number—no fractions or decimals are allowed, and so the score is discrete.
A good rule of thumb is this: if the variable you're measuring has to be rounded before it's written down, then it's continuous. If no rounding is necessary, as with anything that's countable, then it's discrete.
