What is the magnitude of the displacement of the golf ball from t=0 s to t=2.0 s? and What angle does the displacement vector make with the +x axis? angle= degrees.

Actually I'm asking this question because I found my answer for the HW question somewhat weird, but I still can't determine where did I make mistakes. Given: A basketball player can score on a particular shot with p = 0.3. Let S be the number of successes...

I still feel a bit confused, but let's say after all the calculations, I get up to this : P(Z <= -3.36) If I need to look up the normal table, should I change the above to 1 - P(Z >= 3.36) before checking the table? Thank you.

How many hours is it between 2135 hundred military time and 1325 hundred ?

Recall: P(A∪B) = P(A) + P(B) - P(A∩B) do we already given 3 of the unknown for this expression to find P(A∩B) ?
