Answer:
2. tan 280°
3. -tan 80°
Step-by-step explanation:
Your calculator can help you figure this out.
__
The tangent function is periodic with a period of 180°, so tan(100°) will be equal to tan(100°+k·180°) for any integer k. Answer choices include k values of ±1, so two of them are correct:
- tan(100°) = tan(100° -180°) = tan(-80°)
- tan(100°) = tan(100° +180°) = tan(280°)
Answer:
C) $826.82 to $873.18.
Step-by-step explanation:
Sample mean (M) = $850
Standard deviation (s) = $54
sample size (n) = 36
Z for 99% confidence interval (Z) = 2.576
The confidence interval is determined by the following relationship:
Applying the given values, the lower (L) and upper (U) values are:
The answer is C) $826.82 to $873.18.
Answer:
x = 3.1
