Let x be a random variable representing the mean thickness of alutin.

a.) P(2.97 < x < 3.08) = P((2.97 - 3.05)/0.025 < z < (3.08 - 3.05)/0.025) = P(-3.2 < z < 1.2) = P(z < 1.2) - P(z < -3.2) = P(z < 1.2) - [1 - P(z < 3.2)] = P(z < 1.2) + P(z < 3.2) - 1 = 0.88493 + 0.99931 - 1 = 0.88424

Answer:

NO

Step-by-step explanation:

Try to replace x by -50
y= 390 + 11*(-50) = -160
in the table we have -210 so the table doesn't represent the equation

An observer for a radar station is located at the origin of a coordinate system. Find the bearing of an airplane located at the

AfilCa [17]

Answer:

135 degrees

$S45^{0}E$

Step-by-step explanation

Consider the attached diagram

we are required to find the bearing of the aeroplane,

Consider the right angled triangle BOE

|OB|=4 unit

|AB|=4 Units

$Tan \alpha =\frac{Opposite}{Adjacent} =\frac{4}{4} \\\\\alpha=Tan^{-1} 1=45 degrees$

The Bearing of the Aeroplane is therefore given:

(i)From North Clockwise as: 90+45 =135 degrees

(ii)From a North South Line as $S45^{0}E$
