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.
Step-by-step explanation:
x²+y²−8x−2y=48
the radius => √[(8/2)² + (2/2)² +48] =
√(16+1+48) =√65
the center => (8/2, 2/2)
=> (4, 1)
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
If you want the angle it’s 22
In all triangles the angles must add up to 180 so 68 + 90 =158 + 22 =180
sin(π/6) is independent of x, so
