Answer:
Step-by-step explanation:
Reflect over the y-axis: When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed).
Answer:
69%
Step-by-step explanation:
If Motor Works is selected, the probability that the worker is a female is 70%. If City Bank is selected, the probability is 68%.
But we don't know what company will be selected, we only know that they have the same probability, 50-50.
So, with 50% of probability the worker will be female with a 70% of probability (because they selected from Motor Works) and with 50% of probability the worker will be female with a 68% of probability (they selected from City Bank).
We express this as 50%*70% + 50%*68% = 69%
The multiplication means that both probabilities happen together and the sum means that happens one thing or the other (they select Motor Works or City Bank)
Let's analyse the function
The amplitude is A, so we want A=1.5
Now, we start at x=0, and we have 
After one second, i.e. x=1, we want this sine function to make 330 cycles, i.e. the argument must be 
So, we have
so, the function is
