Answer:
anyone know the real answer please i need helpppppppp
Step-by-step explanation:
please
We are given with the equation
1/sin 18 - 1/sin 54 = 2
We are meant to verify if the equation is true
So,
(sin 54 - sin 18)/ sin 18 sin 54 = 2
sin 54 - sin 18 = 2 sin 18 sin 54
sin 18*3 - sin 18 = 2 sin 18 sin 18*3
Use trigonometric identities to verify the equation.
The identities to use are the double and product of angles.<span />

Answer:
The point estimate for p is 0.5637.
Step-by-step explanation:
Point estimate for the proportion of all judges who are introverts.
We have a big sample.
So the proportion of the sample proportion of introverted judges can be used as the estimation of the population proportion.
In the sample:
502 judges
283 introverts.
So
p = 283/502 = 0.5637
The point estimate for p is 0.5637.
