Answer:
144 = arc DF
Step-by-step explanation:
Inscribed Angle = 1/2 Intercepted Arc
72 = 1/2 arc DF
Multiply by 2
2*72 = arc DF
144 = arc DF
Answer:
92
Step-by-step explanation:
(-20,-57)-(-6,-9)=(-26,-66)
-26+-66=-92
|-92|
Answer:
Raise 9 to the power of 11.
= 31381059609
Step-by-step explanation:
The margin of error (MOE) can be calculated by using the
formula:
MOE = 1.96 sqrt [p (1 – p) / n]
So substituting the values:
MOE = 1.96 sqrt [0.5 (1 – 0.5) / 400]
MOE = 0.049
Therefore answer:
