Answer:
The best estimate of the proportion of adults who say that the law goes easy on celebrities is 0.7435.
Step-by-step explanation:
Confidence interval concepts:
A confidence interval has two bounds, a lower bound and an upper bound.
A confidence interval is symmetric, which means that the point estimate used is the mid point between these two bounds, that is, the mean of the two bounds.
In this question:
CI is between 0.645 and 0.842. So the best estimate of the proportion is:
(0.645+0.842)/2 = 0.7435
The best estimate of the proportion of adults who say that the law goes easy on celebrities is 0.7435.
Answer:
216°
Step-by-step explanation:
Both chords are the same length, so the left and right arcs are both 72°. The whole circle is 360°, so:
72° + 72° + x = 360°
x = 216°
The answer would be 16 3/4 divided by 3 7/8
Answer:
7.39 ( nearest hundredth )
Step-by-step explanation:
Using the rule of logarithms
= n ⇔ x = 
Note that ln x represents 
x
given 6 + ln x = 8 ( subtract 6 from both sides )
ln x = 2 ⇒ x = 
≈ 7.39
