Answer:
Step-by-step explanation:
Given that a cheese can be classified as either raw dash milk or pasteurized. Suppose that 91% of cheeses are classified as pasteurized.
Each cheese is independent of the other and there are only two outcomes.
Hence X = no of cheeses pasteurized is binomial (2,0.91)
a) P(x=2 ) when n=2 is
b) n=6.
P(x=6) =
c) P(atleast one raw dash milk) = 1-P(all pasteurised)
=0.8281
Since probability is 0.83 it is not unusual.
Answer:
7330 sq.ft
Step-by-step explanation:
Area covered by the beam = Area of sector
Area of sector =
Where,
Radius (r) = 100 ft
Plug in the values into the formula
Area of sector =
Area of sector =
Area of sector = 7,330 ft² (nearest square foot)
Answer:
Area of the triangle WXY = 111.8 mm²
Step-by-step explanation:
By applying Sine rule in the given triangle WXY,
Since m∠W + m∠X + m∠Y = 180°
m∠W + 26° + 130° = 180°
m∠W = 180° - 156°
m∠W = 24°
XY =
XY = 16.4597
≈ 16.4597 mm
Area of the triangle =
=
= 111.83 mm²
≈ 111.8 mm²
Therefore, area of the triangle WXY = 111.8 mm²
