Null hypothesis:
Alternative hypothesis:
And we can use a t test procedure in order to check if the true mean is equat to the desired value.
Answer:
Second one
Step-by-step explanation:
They have one angle (R) in common
Also,
Angles T & S and P & Q are equal because they are corresponding angles.
RS/RT = SQ/TP
4/(4+4) = 2x/(x+6)
4x = x + 6
3x = 6
x = 2
SQ = 2(2) = 4
TP = 2 + 6 = 8
Answer:
* is 
Step-by-step explanation:
(7x + 3)(x + 3)
= + 24x + 9
