Answer:
(364.595 ; 391.405)
Step-by-step explanation:
Given the sample data:
406, 385, 389, 383, 352, 379, 388, 343, 368, 387
Using calculator :
Sample mean, xbar = 378
Standard deviation, s = 18.74
Confidence interval :
Xbar ± Margin of error
Margin of Error = Tcritical * s/√n
TCritical at df = 24 ; 0.05 = 2.262
Margin of Error = 2.262 * 18.74/√10 = 13.405
Lower boundary = (378 - 13.405) = 364.595
Upper boundary = (378 + 13.405) = 391.405
(364.595 ; 391.405)
Answer:
2x = 120°, x = 60°, y = 60°
Step-by-step explanation:
2x + x = 180° (eternal angles in a parrallel lines add up to 180°)
3x = 180. divide by 3 in both sides.
x = 60
therefore:
2x = 2(60) = 120°
x = 60°
y = x (crossponding).
if x = 60°, then y = 60°
Done :D
Answer:
There are 5 solutions
Step-by-step explanation:
Answer:
AE
Step-by-step explanation:
Because it intersects with EJ.
Whereas skew lines are those that do not inersect and not parallel with each other.
Hope it helps :)
