Answer:

Factors of the expression given in the question i.e 9y² - 12y + 4 is (3y -2)(3y -2) .

Step-by-step explanation:

As the expression is given in the question be .

= 9y² - 12y + 4

Simplify the above

= 9y² -6y -6y + 4

= 3y (3y -2) -2 (3y - 2)

= (3y-2)(3y-2)

Therefore factors of the expression given in the question i.e 9y² - 12y + 4 is (3y -2)(3y -2) .

The question is $9y^{2}$ -12y +4, right?

The answer is (3y-2)(3y-2) or $(3y-2)^{2}$

The thickness of a flange on an aircraft component is uniformly distributed between 0.95 and 1.05 millimeters. (a) Determine the

maxonik [38]

Answer:

a) 0.5 = 50% of flanges exceed 1 millimeter.

b) A thickness of 0.96 millimeters is exceeded by 90% of the flanges

Step-by-step explanation:

A distribution is called uniform if each outcome has the same probability of happening.

The uniform distributon has two bounds, a and b, and the probability of finding a value higher than x is given by:

$P(X > x) = \frac{b - x}{b - a}$

The thickness of a flange on an aircraft component is uniformly distributed between 0.95 and 1.05 millimeters.

This means that $a = 0.95, b = 1.05$

(a) Determine the proportion of flanges that exceeds 1.00 millimeters.

$P(X > 1) = \frac{1.05 - 1}{1.05 - 0.95} = \frac{0.05}{0.1} = 0.5$

0.5 = 50% of flanges exceed 1 millimeter.

(b) What thickness is exceeded by 90% of the flanges?

This is x for which:

$P(X > x) = 0.9$

$\frac{1.05 - x}{1.05 - 0.95} = 0.9$

$1.05 - x = 0.9*0.1$

$x = 1.05 - 0.9*0.1$

$x = 0.96$

A thickness of 0.96 millimeters is exceeded by 90% of the flanges
