Answer:
x = 65
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
subtract the sum of the 2 given angles from 180° for third angle
third angle = 180° - (60 + 55)° = 180° - 115° = 65°
65° and x are vertical angles and are congruent, thus
x = 65
Answer:
10
Step-by-step explanation:
the radius is from center out.
3 rows x 5 chocolates= 15 pieces per layer
15 pieces x 5 layers= 75 chocolates
Answer:
Follows are the solution to the given points:
Step-by-step explanation:
In point A:

In point B:

In point C:
For df = 70, the top 5% critical t score
tcrit = 1.666914479
Thus,

In point D:
For df = 70, the top 5% critical t score
tcrit = -1.666914479

In point E:
The lower cutoff is 0.10 in the center, which would be around 80 %. The critical point therefore is
tcrit = -1.293762898

In point F:
The lower cutoff is 0.90 in the center, which would be around 80 %. The critical point therefore is
tcrit = 1.293762898
