Tanzania [10]
Let's set up the problem. First, we know Texas is 270,000 square miles, and this is 41% the size of Alaska.
So 270,000=41%(size of Alaska), or 270,000=.41(x). Now solve for x to find the size of Alaska.

Find the radius and the center of the circle with the given equation x^2+y^2−8x−2y=48.
Semmy [17]

Step-by-step explanation:

x²+y²−8x−2y=48

the radius => √[(8/2)² + (2/2)² +48] =

The diameters of ball bearings are distributed normally. The mean diameter is 130 millimeters and the variance is 9. Find the pr
Crank

Answer:

0.0478

Step-by-step explanation:

We solve using z score formula

z = (x-μ)/σ, where

x is the raw score = 135 mm

μ is the population mean = 130 mm

σ is the population standard deviation.

We are given variance = 9

Standard deviation = √variance = √9 = 3

Hence

z = 135 - 130/3

z = 1.66667

Probability value from Z-Table:

P(x<135) = 0.95221

P(x>135) = 1 - P(x<135) = 0.04779

Approximately to 4decimal places = 0.0478
