Answer:
0.98
Step-by-step explanation:
Work Shown:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.13 + 0.85 - 0
P(A or B) = 0.98
Note that P(A and B) is 0. This is because we are told A and B are mutually exclusive events. This means both events cannot happen simultaneously. An example would be flipping a coin to have it land on heads and tails at the same time.
Answer:
Step-by-step explanation: the best way to get this answer is by using a scientific calculator fx-991es plus I recommend
Let's go manual for now.
Let's covert pi/4 to angle
1⁰ =π/180
1 radian =180/π
Therefore π/4 × 180/π
∅ =45⁰
Sin-¹(tan 45⁰)
Tan 45⁰= 1
Sin-¹ (1) = 90⁰. Press { sin,-¹ (1) } on your calculator
Sin-¹ (tan pi/4) = 90⁰
I think it’s C cause it’s never ending but not repeating at the same time
The does this differ from the original points is -32.5
