A hypothesis used to test that
against the alternatives 
not equal to 10
if null hypothesis is true, then distribution of test statics follow
for two sided alternatives hypothesis 
, then P value is

Answer:
x = 8.5
Step-by-step explanation:
You have all three angles already, so it's easy: 90°, (4x - 8)°, (6x + 13)°
The sum of all angles is 180°
90 + (4x - 8) + (6x + 13) = 180
10x + 95 = 180
- 95 -95
10x = 85
x = 8.5
Answer:
X=2
Step-by-step explanation:
If a number can be written or can be converted to p/q form, where p and q are integers and q is a non-zero number, then it is said to be rational and if it cannot be written in this form, then it is irrational.
