450/15 = 30 mpg -- Adam's
416/13 = 32 mpg -- Kenny's

Kenny is going to get the better gas mileage at 32 mpg (miles per gallon)

Measuring the height of a tree is usually more difficult than measuring the diameter of the tree. Therefore, many researchers us

LenKa [72]

Answer:

(B) (0.396, 1.712)

Step-by-step explanation:

From the information given;

Confidence Interval = 0.95

Significance Level $= 1 - 0.95 = 0.05$

The confidence interval for regression coefficient beta (whereby in this case it is the coefficient of the diameter) is expressed by:

= $( Beta ^- \ t_{n-2}, \alpha/2 ( S.E \ of \ \^ \ \ ), Beta^+ \ t_{n-2}, \alpha/2 ( S.E \ of \ \^ \ \ ))$

From the regression coefficient, the estimated value of beta^ = 1.054

$= (1.054 - t_{29,0.025} *(0.322), 1.054 + t_{29,0.025}*(0.322))$

$t_{229,0.025} = 2.0452\\\\ = \mathbf{(0.396, 1.712)}$

What is the radius of the cone?

gayaneshka [121]

Answer:

r = 6 in

Step-by-step explanation:

$V = \pi r^{2} \frac{h}{3}$ = $216\pi$

r²h/3 = 216

r² (18/3) = 6 r² = 216

r² = 216/6 = 36

r = 6
