Converting an equation into inverse function, we need to interchange x with the y.
f(x) = 1/9x + 2
y = 1/9x + 2
Interchange x and y
x = 1/9y + 2
Get the y.
-1/9y = -x + 2
1/9y = x - 2
y = 1/9x - 2/9
So the final answer is
<span>y = 1/9x - 2/9</span>
Exact = 609.
Estimate to 10s = 610.

Answer:
Hi there!
Your answer is:
The rod is equal to $5
The reel is equal to $105
Step-by-step explanation:
Rod= R
Reel= E
Rod = R
E= 100+r
(100+R)+R= 110
100+ 2R= 110
-100
2R = 10
/2
R= 5
E= 100+5
The rod is equal to $5
The reel is equal to $105
Answer:
[ 0.4964, 0.5836 ]
Step-by-step explanation:
Data provided in the question:
Total sample size = 500
person voting for smith = 270
thus,
P( person voting for smith ), p =
= 0.54
Confidence level = 95%
now,
standard error, SE = 
or
SE = 
or
SE = 0.0223
now,
Confidence interval = p ± ( z × SE )
here,
z value for 95% confidence interval is 1.96
Confidence interval = [ 0.54 - ( 1.96 × 0.0223 ), 0.54 + ( 1.96 × 0.0223 ) ]
= [ 0.54 - 0.0436 , 0.54 + 0.0436 ]
= [ 0.4964, 0.5836 ]
