Answer:
1st one is "square root of 2x"
2nd one is "2 square root of x"
3rd one is "is not"
Step-by-step explanation:
1st one: you have 2x for g(x) then you plug that into the x for f(x) giving you square root of 2x
2nd one: you have square root of x for f(x) then you plug that into the x for g(x) giving you 2 square root of x
3rd one: the inverse of the square root of x is x^2
Answer:
(19228.737 ; 20771.263)
Step-by-step explanation:
Given that:
Sample size, n = 17
Sample mean, m = 20,000
Sample standard deviation, s = 1500
α = 95%
The confidence interval,
Mean ± margin of error
Margin of Error : Tcritical * s/sqrt(n)
Tcritical at α = 0.05 ; df = n-1 = 17 - 1 = 16 ; 2 - tailed test = 2.120
Margin of Error = 2.120 * 1500/sqrt(17) = 771.263
Lower boundary :
20,000 - 771.263 = 19228.737
Upper boundary :
20,000 + 771.263 = 20771.263
Confidence interval :
(19228.737 ; 20771.263)

Answer:
The area of one trapezoidal face is 2 square inch
Step-by-step explanation:
Area of a trapezoid is calculated as follows:
A = (a + b)/2 * h
where a, b and h are the lengths of the top side, the base and the height, respectively. Replacing with data:
A = (1 + 3)/2 * 1
A = 2 square inch
The population in 1992 was 83 mill....population is 1996 was 88 mill...
so in 4 years (from 1992 to 1996), the population rose by (88 mill - 83 mill) = 5 mill
Thats 5,000,000 / 4 = 1,250,000 per year.
so in 2013 (17 years from 1996), the population would be :
83 mill + 1,250,000(17) = 83 mill + 2,125,000 = 85,125,000 <==
