Answer:
1 13/15
Step-by-step explanation:
3−1=2
10/15−12/15=−2/15
2−2/15=1 13/15
Answer:
Your answer is B. Tell me if you need graphics)
Mean = 110
Sample size = 45
Standard deviation = 6
Z score for 90% is 1.645 ( from Z-table).
Lower Limit = Mean - Z(SD/√Sample size))
Lower limit = 110 - 1.645(6/√45)
Lower limit = 108.5
Upper Limit = Mean + Z(SD/√Sample size))
Lower limit = 110 +1.645(6/√45)
Lower limit = 111.5
The interval is (108.5, 111.5)
Answer:cot t = 1.875
but sin²t + cos²t = 1 ⇔ cos²t = 1 - sin²t
⇔cos t = 
but t is a quadrant III angle => cos t = 
=> cot t =
