Answer:
-i
Step-by-step explanation:
We are to find the value of i^31
Note that i^2 = -1
Expanding i^31
i^31 =
= (i^2)15 * i
= (-1)^15 * i
= -1 * i
= -i
Hence the equivalent is -i
Answer:
A, B and E could not be probabilities
Step-by-step explanation:
By definition, <u>a probability could be any number between 0 and 1. </u>So a probability P would be 0≤P≤1. In percentages, 0% ≤ P ≤ 100%
Considering this we would have that:
A) 110% could not be a probability because it's larger than 100%
B) 5.42 could not be a probability because it's larger than 1.
C) 0.001 could be a probability because it's larger than 0 and smaller than 1 (It doesn't matter how small it is)
D) 0.58 could be a probability because it's between 0 and 1.
E) -120% could not be a probability because it's smaller than zero. (it's a negative number)
Thus, A), B) and E) could not be probabilities.
Answer:
a. $3,333.33
b. $223,333.31
Step-by-step explanation:
a. $50,000 value increase and difference of 15 years 50,000/15 = 3,333.333333= 3333.33
b. difference 2006 and 1999 is 7 years, growth by year is $3333.33 so 3333.33 * 7 = 23,333.31 is difference in growth in those 7 years plus the original value of 1999 is $223,333.31
Answer: 1163.2 feet
