Answer:
Range of is (−5,11).
Step-by-step explanation:
Given the invertible function Ф(x) which has the domain (−5,11) and the range (−12,1).
Invertible function is the function that inverses another function i.e if y=Ф(x) then x=g(y) where g is called the inverse of Ф and denoted by
Given Ф(x) the function whose domain is (−5,11) and range is (−12,1). Therefore, by definition of invertible function there exist a function g with domain (−12,1) and range (−5,11) which is called the inverse function denoted by
Hence, Range of is (−5,11)
Answer: C
Step-by-step explanation:
<u>Given:</u>
Sample size (n) = 50
x = 12
Confidence level = 90%
α = 1 − 0.90 = 0.10
α/2 = 0.05
(from standard normal table)
90% Confidence interval is,
Therefore, 90% confidence interval for the true proportion of sophomores who favour the adoption of uniforms is C
