Answer:
Step-by-step explanation:
Given :
From rules of probability :
........................... equation *
can be written as x
Also , can be written as x
substituting into equation * , we have
since P(B) = 0.7, then
so , substituting each values , we have
In this order going from left to right:
Substitute 4 for g
Substitute 9 for f
9-4
5
Hope this helps!
Step 2
because she should substitute the negative sign to 6
Answer:
Step-by-step explanation:
Given that,
Hudson Bay tides vary between and .
Tide is at its lowest when
Completes a full cycle in 14 hours.
To find:- What is the amplitude, period, and midline of a function that would model this periodic phenomenon?
So, The periodic function of this model is
...................(1)
where,
Then putting the value in given Equation(1) we get,
Amplitude =
Now, At it complete full cycle in because it is at lowest at t=0sec.
∵
∴
Hence
