Simplify the following:
(5 i^3 t^4)/7 - 2
i^3 = i^2×i = (-1) i = -i:
(5×-i t^4)/7 - 2
Put each term in (5 (-i) t^4)/7 - 2 over the common denominator 7:
(5 (-i) t^4)/7 - 2 = (-5 i t^4)/7 - 14/7:
(-5 i t^4)/7 - 14/7
(-5 i t^4)/7 - 14/7 = (-5 i t^4 - 14)/7:
Answer: (-5 i t^4 - 14)/7

Answer:
The value of the test statistic 
Step-by-step explanation:
From the question we are told that
The high dropout rate is
% 
The sample size is 
The number of dropouts 
The probability of having a dropout in 1000 people 
Now setting up Test Hypothesis
Null 
Alternative
The Test statistics is mathematically represented as

substituting values


Answer:
5.625
Step-by-step explanation:
So first do 112 / 360
Simplify it = 28 / 90 = 14 / 45
So 1.75 is 14 / 45 of the circumference.
The whole circumference is 1.75 * (45 / 14)
So the answer is 45 / 8 = 5.625
