25%
the last part was unformatted and i cant tell what it is, but point b after translated is (-2,3)
Answer:
See proof below
Step-by-step explanation:
In trigonometry identity
tan^2 theta = sin^2 theta /cos^2 theta
cot^2 theta = cos^2 theta/sin^2 theta
csc^2 theta = 1/sin^2 theta
Substitute into the expression
(sin^2 theta /cos^2 theta )+ (cos^2 theta/sin^2 theta)/1/sin^2 theta
= [sin^4theta + cos^4theta/cos^2 theta sin^2 theta]÷(1/sin^2 theta)
= 1/cos^2 theta sin^2 theta÷(1/sin^2 theta)
= 1/cos^2 theta sin^2 theta * sin^2 theta/1
= 1/cos^2theta
= sec^2theta (Proved!)
Answer: 95% confidence interval would be (175.04,194.96).
Step-by-step explanation:
Since we have given that
Mean = 185 mg
Standard deviation = 17.6 mg
At 95% confidence level, z = 1.96
So, Interval would be
Hence, 95% confidence interval would be (175.04,194.96).
