The question requires that we calculate the theoretical probability of landing on the head.
This means that, we have to ignore the given data, and we use the following
--- sample space
--- sample size
--- occurrence of Head
So, the theoretical probability is:



Answer:

Step-by-step explanation:
x² = 19x + 12
⇔ x² - 19x - 12 = 0
Calculating the discriminant :
b² - 4ac = (-19)² - 4×1×(-12) = 409
The discriminant is positive ,then the equation has two solutions.

Answer:
No for both
Step-by-step explanation:
If 2 x values that are the same but different y values for them then its not a function
You would do 375 divided by 60% and get 6.25 if need to round to nearest whole it would be 6
