Explanation:
The probability that she wins is m/n, where m,n are placeholders for positive whole numbers.
For instance, m = 2 and n = 5 leads to m/n = 2/5. This would mean that out of n = 5 chances, she wins m = 2 times.
The probability of her not winning is 1 - (m/n). We subtract the probability of winning from 1 to get the probability of losing.
We could leave the answer like this, but your teacher says that the answer must be "in the form of a combined single fraction".
Doing a bit of algebra would have these steps
and now the expression is one single fraction.
Answer:
The concentration of hydrogen ions in moles per liter (M) is
Step-by-step explanation:
As we know
The hydrogen ion concentration of any solution at pH is given by
Substituting the given values in above equation, we get -
mol/l
The concentration of hydrogen ions in moles per liter (M) is
Answer:
15 Kg cm²
Step-by-step explanation:
Given that V varies inversely with P then the equation relating them is
V = ← k is the constant of variation
To find k use the condition
V = 360, P = 20, then
360 = ( multiply both sides by 20 )
k = 7200
V = ← equation of variation
When V = 480, then
480 = ( multiply both sides by P )
480P = 7200 ( divide both sides by 480 )
P = 15
