Answer:
-2.03, 2.03
Step-by-step explanation:
The degree of freedom (df) ;
Df total for the two samples = 35
Therefore, obtuaking the critical value using a T-test distribution at 95% confidence level.
(1 - 95%) / 2 = (1 - 0.95) / 2 = 0.05 / 2 = 0.025
Using a T critical value calculator or t table distribution ;
Tcritical, 0.025, df = 35 = 2.03
Left tail = - 2.03
Right = 2.03
Hence, critical cutoff :
(-2.03 ; 2.03)
Answer:
No, all angles in any triangle must add up to 180.
The answer is 192
1x64=64
2x64=128
3x64=192
Answer:
Option 2.
Explanation:
That method is the most random in order to decide what students should take the survey.
X^2 -(y^2-x-1). >>simplify
=x^2+ (-4)(y^2)+(-4)(-x)+(-4)(-1). >>>> distribute
= x^2 -4y^2 + 4x +4 >>>>answer
