Answer:
A: 8/31
B: 5/13
C: The events are dependent because one happening doesn't effect the other happening, sometimes it just happens that it rains and snows on the same day
Step-by-step explanation:
A - A is 8/31 because of the 31 days 8 of them snow (combined from snow and both)
B - There are 13 days that it rains and on 5 of those days it also snows

Step-by-step explanation:
PH
is a scale which measures the acidity or alkalinity of a solution. It ranges
from a level of 1 to 14. A pH which range from 1 to 6 represents an acidic
substance. At pH of 7, signifies the solution is neutral. And at a pH of 8-14
represents a basic solution. pH is expressed as the negative logarithm of the
concentration of hydronium ions. To determine the factor of how the pH will change, we use the definition of the pH.<span>
pH = -log [H+]
5.50 = -log [H+]
[H+] = 10^-5
2.00 = -log [H+]
[H+] = 10^-2
</span>10^-5 / 10^-2 = 0.001
The rate of reaction would change by a factor of 0.001 as the pH change from 5.5 to 2.0
Answer:
q = 8
Step-by-step explanation:
Given the 2 equations
p + q = 36 → (1)
p - q = 20 → (2)
Add the 2 equations term by term
2p = 56 ( divide both sides by 2 )
p = 28
Substitute p = 28 into (1)
28 + q = 36 ( subtract 28 from both sides )
q = 8
