Step-by-step explanation:
thats right on edge
180 degrees. in an equilateral triangle, each angle is 60 degrees
Step-by-step explanation:
g(t) = (t + 1)² − 20.25
0 = (t + 1)² − 20.25
20.25 = (t + 1)²
±4.5 = t + 1
t = -1 ± 4.5
t = -5.5 or 3.5
The zeros are (-5.5, 0) and (3.5, 0).
Answer: 0.0084
Step-by-step explanation:
Let p be the population proportion of the creatures in Wonderland are anthropomorphic animals.
As per given, p = 0.70
Sample size : n=120
Let be the sample proportion of the creatures are anthropomorphic animals.
Now, required probability :
Hence, the probability that more than 80% of the sampled inhabitants are animals= 0.0084
