A commuter encounters four traffic lights each day on her way to work. Let X represent the number of these that are red lights. The probability mass function of X is: P(X=0)=0.12, P(X=1)=0.26, P(X=2)=0.31, P(X=3)=0.22, and the rest is P(X=4). Assuming normal distribution, what is the probability that in a period of 100 days, the average number of red lights encountered is more than 2 per day? Express your answer in decimals."

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

step-by-step explanation:

(53.5 - 18.4) m.

step-by-step explanation:

after undergoing a displacement of 18.4m, the initial position was (53.5 - 18.4) m if an object has a final position of 53.5.

hello there!

i believe the answer is

(cot2+1)/sec2=cot2

    csc2/sec2=cot2

  (1/sin2)/(1/cos2)=cot2

  (1/sin2)(cos2/1)=cot2

  cos2/sin2=cot2

  (1/tan2)=cot2

  (cot2)=(cot2)

hope this !
