Answer:
(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
Answer:
z = 15 degrees, 5z = 75 degrees
Step-by-step explanation:
AYB is 180 degrees
CYD is 90
so the two missing angles sum to 180 - 90 = 90
z + 5z = 90
6z = 90
z = 15
5z = 75
The ANWSER is 16 I don't think I can show you a area model try your best you can make 64 squares the get and put them into groups of 4 if that helps and there should be 16 groups
