For 95% CI
x - 0.05s = 100
x + 0.05s = 120
Solve for x and s
The interval for u with 90% is
x - 0.10s
and
x + 0.10s
Substitute x and s
Answer:
center (0;0), vertices (0;10) and (0;-10), foci (0;6) and (0;-6)
Step-by-step explanation:
Answer:
It is the third one down.
Step-by-step explanation:
The two smaller angles would be the same measurement because the angle bisector cuts the big angle down the middle. So, if the big angle was 90°, the two smaller angels would be 45°.
the answer would be 6 planes
(10 + 9) x (3 - 1) x 2 = +75
19 x 2 x 2
76
76 > 75
