We will find the inverse of the given functions:
 y = x + 2 / x-2
 (x-2) y = x + 2
 -2y + xy = x + 2
 -2y + xy = x + 2
 x (y - 1) = 2 + 2y
 x (y - 1) = 2 (y + 1)
 x = 2 (y + 1) / (y - 1)
 f (x) ^ - 1 = 2 (x + 1) / (x - 1)
 The inverse is different.
 f (x) = x + 1 / x-1
 
y = x + 1 / x-1
 (x-1) y = x + 1
 -y + xy = x + 1
 x (y - 1) = 1 + y
 x (y - 1) = (y + 1)
 x = (y + 1) / (y - 1)
 f (x) ^ - 1 = (x + 1) / (x - 1)
 The inverse is the same.
 Answer:
 
f (x) = x + 1 / x-1
 
f (x) ^ - 1 = (x + 1) / (x - 1)
 f (x) = f (x) ^ - 1

Construct a 95% prediction interval for y given x=-3.5, ^y= 2.097x - .552 and se= .976​
Rasek [7]

Answer:

95% Confidence interval for y

= (-9.804, -5.979)

Lower limit = -9.804

Upper limit = -5.979

Step-by-step explanation:

^y= 2.097x - 0.552

x = -3.5

Standard error = 0.976

Mathematically,

Confidence Interval = (Mean) ± (Margin of error)

Mean = 2.097x - 0.552 = (2.097×-3.5) - 0.552 = - 7.8915

(note that x=-3.5)

Margin of Error is the width of the confidence interval about the mean.

It is given mathematically as,

Margin of Error = (Critical value) × (standard Error of the mean)

Critical value for 95% confidence interval = 1.960

Standard Error of the mean = 0.976

95% Confidence Interval = (Mean) ± [(Critical value) × (standard Error of the mean)]

CI = -7.8915 ± (1.960 × 0.976)

CI = -7.8915 ± 1.91296

95% CI = (-9.80446, -5.97854)

95% Confidence interval for y

= (-9.804, -5.979)

Hope this Helps!!!

What is the exact volume of the cone?
victus00 [196]
Answer:  [D]:  " 196π  in.³  "  .
_____________________________________________________
Explanation:
_____________________________________________________
Given: radius, "r", equal 7 in.
Given: height, "h", equals 4 in.

Volume:  V = Base area * h ; 

The base area of a cone is a circle:  A = π * r²  = π* (7²) = 49π .

(NOTE: Since all answer choices given are in terms of "π" ; we will leave the units in terms of "π").

V = (Based area) * h = (49π  in.) * (4 in.) = (49*4)π  in.³
   =  196π  in.³  ; which is: Answer choice: [D] .
