Answer:
Median = 31
Step-by-step explanation:
The median is the middle number which comes after arranging the set in ascending order.
Here, the given data is: 28, 45, 12, 34, 36, 45, 19, 20
The data arranged in the ascending order is as follows:
12, 19, 20, 28, 34, 36, 45, 45
Since the number of terms is even, we have two middle numbers, viz.,
28 and 34
The median would be the average of these two.
Therefore, Median =
= 31
The answer is 31.
Answer: y2/4 - x2/5
Step-by-step explanation:
This queston is not of Algebra. It is of chemistry.
You have to work with the chemical formula of the compound, the atomic and molar masses and use proportions.
1) PH3:
element atomic mass number of atoms total mass
P 31 g/mol 1 31 g/mol
H 1.0 g/mol 3 3.0 g/mol
------------------
molar mass 34 g/mol
2) proportions
372 g H / x = 3.0 g H / 34 g PH3
=> x = 372g H * 34 g PH3 / 3.0 g H = 4216 g PH3
Answer: 4216 g
