After 4 years
the value = 1000 × (1.1)⁴
the value = 1000 × 1.4641
the value = 1464.1
Answer:
a) 0.0821
b) 0.0111
c) 0.0041
Step-by-step explanation:
Exponential distribution:
The exponential probability distribution, with mean m, is described by the following equation:

In which
is the decay parameter.
The probability that x is lower or equal to a is given by:

Which has the following solution:

Either it lasts more 5 years or less, or it survives more than 5 years. The sum of the probabilities of these events is decimal 1. So

In all 3 cases, we want P(X > 5). So

In which

(a) lambda=.5


(b) lambda=0.9


(c) lambda=1.1


Answer: C. 6 1/6
Step-by-step explanation:
2 * -5 * -7 = -10 * -7 = 70
70 + 4 = 74
3 * 4 = 12
74/12 = 6 1/6
Answer:
C
Step-by-step explanation:
Yes, ACD = BCD by AAS since they have 2 congruent angles & share a side.
