Answer:
the experimental group would be the teachers who recieved the candy
control group would be the teachers who dont get any candy
<em>Explanation:</em>
experimental group is the group that receives the test variable being tested in this case the variable being the candy
and the control group is the group who doesn't receive the variable
purpose of having a control is to rule out other factors which may influence the results of an experiment.
15.9643 gramns are in 2.3 moles of lithium
C is the correct answer since it outputs and inputs chemicals
We have to calculate formula mass of N₂O.
The answer is: 44
Relative formula mass is the sum of relative atomic mass of constituent atoms in a formula unit of any compound. Relative formula mass is represented as same symbol of relative molecular mass.
To calculate relative formula mass we need to know number of each atom in the formula and then adding atomic masses of all the atoms.
In N₂O, number of N-atom present is equal to 2 and number of O-atom is equal to 1.
Atomic mass of N-atom is 14 and atomic mass of O-atom is 16.
So, formula mass of N₂O is (2 X 14)+16 = 44.
The Probability of spending at least half an hour on exactly one subject is mathematically given as
P(1)= 0.50
<h3>What is the
Probability of spending
at least
half an
hour on exactly one
subject </h3>
Question Parameters:
The amount of study time that Actuary Tong will spend on each exam in a day follows a continuous random variable that ranges from 0 to 1 hour.
Generally, the equation for the Probability of spending at least half an hour on a subject is mathematically given as
P(A)= (1 – 0.5)/(1 – 0)
P(A)= 0.5
Hence, the Probability of spending at least half an hour on exactly one subject is mathematically given as
P(1)=2C1 * 0.5 * 0.5
P(1)= 0.50
