Answer:
The 95% confidence interval of the proportion of Americans who believe in the conspiracy is
Step-by-step explanation:
From the question we are told that
The sample size is n =1057
The number that believe there was a conspiracy is k = 614
Generally the sample proportion is mathematically represented as

=> 
From the question we are told the confidence level is 95% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of
is
Generally the margin of error is mathematically represented as
=>
=>
Generally 95% confidence interval is mathematically represented as
=>
=>
Answer:
V = 267.95
Step-by-step explanation:
Volume of a Sphere:
V = 4/3πr³
r = d/2
r = 4
Work:
V = 4/3πr³
V = 4/3(3.14)(4³)
V = 4/3(3.14)(64)
V = 267.95
Answer:
Angles G and H are congruent.
Step-by-step explanation:
To compare ratios, write them as fractions. The ratios are equal if they are equal when written as fractions.
Let us assume the following units of measure:
Length = 10 inches
Width = 5 inches
Height = 8 inches
Surface area = 2lw + 2wh + 2lh
S.A = 2(10in * 5in) + 2(5in * 8in) + 2(10in * 8in)
S.A = 2(50in²) + 2(40in² + 2(80in²)
S.A = 100in² + 80in² + 160in²
S.A = 340 in²
Volume = lwh
V = 10 in * 5 in * 8 in
V = 400 in³
ratio of the surface area to volume?
340 in² / 400 in³ = 34 / 40 in = 17/20 in
