Imma need help om these 7 next questions, i will post them back to back According to this partial W-2 form, how much money was paid in FICA taxes?

$2134.88

$2653.97

$3274.66

$8417.41

(a) $54

(b) $60

(c) $30

(d) $6.3

Step-by-step explanation:

Suppose a month has 30 days. Then the expected expense for the whole month is 30 times the expected expense at each day

(a) E[F] = 30*30%*$6 = 30*0.3*6 = $54

(b) E[T] = 30*50%*$4 = 30*0.5*4 = $60

(c) E[C] = 30*4%*$25 = 30*0.04*25 = $30

(d) Suppose all events are independent, the probability that she would spend on all 3 items on the same day is

P[F+T+C] = 0.3*0.5*0.04 = 0.006

So the expected expense she would make on all 3 items is

E[F+T+C] = 30*0.006*(6+4+25) = $6.3
