Step-by-step explanation:

A machine operation produces bearings whose diameters are normally distributed, with a mean of 0.497 inch and a standard deviati
eduard
Mean = 0.497 in, SD = 0.003 in
Required diameter ranges between 0.496 in and 0.504 in
Anything other diameter obtained is not acceptable.

That is;
P(x<0.496) and P(x>0.504) are not acceptable.

Now,
P(x<0.496) = P(Z< (0.496-0.497)/0.003)) = P(Z<-0.33)
From Z tables, P(Z<-0.33) = 0.3707

Similarly,
P(x>0.504) = P(Z> (0.504-0.497)/0.003)) = P(Z>2.33)
From Z tables, P(Z>2.33) = 1-0.9901 = 0.0099

Therefore, unacceptable proportion = P(x<0.496)+P(x>0.504) = 0.3707+0.0099 = 0.3806 or 38.06%

Which statement is true about the equation? 3y-6x=-3
Mekhanik [1.2K]
<span>B.When x=-4, y=-9 and when x=2, y=3.

</span><span>3y-6x=-3
3(-9) - 6(-4)= -3
-27 +24 =-3
-3 = -3

</span>
<span>3y-6x=-3
3(3) -6 (2) = -3

8/x2+6x times 2x product
sergejj [24]

Answer:

4 • (3x4 + 2)

 ———————

      x2    

Step-by-step explanation:

Step  1  :

            8

Simplify   ——

           x2

Equation at the end of step  1  :

  8    

 —— +  12x2

 x2    

Step  2  :

Rewriting the whole as an Equivalent Fraction :

2.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  x2  as the denominator :

           12x2     12x2 • x2

   12x2 =  ————  =  —————————

            1          x2    

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

8 + 12x2 • x2     12x4 + 8

—————————————  =  ————————

     x2              x2  

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  12x4 + 8  =   4 • (3x4 + 2)

Polynomial Roots Calculator :

3.2    Find roots (zeroes) of :       F(x) = 3x4 + 2

Polynomial Roots Calculator is a set of methods aimed at finding values of  x  for which   F(x)=0  

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers  x  which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number  P/Q   then  P  is a factor of the Trailing Constant and  Q  is a factor of the Leading Coefficient

In this case, the Leading Coefficient is  3  and the Trailing Constant is  2.

The factor(s) are:

of the Leading Coefficient :  1,3

of the Trailing Constant :  1 ,2

Let us test ....

  P    Q    P/Q    F(P/Q)     Divisor

     -1       1        -1.00        5.00    

     -1       3        -0.33        2.04    

     -2       1        -2.00        50.00    

     -2       3        -0.67        2.59    

     1       1        1.00        5.00    

     1       3        0.33        2.04    

     2       1        2.00        50.00    

     2       3        0.67        2.59    

Polynomial Roots Calculator found no rational roots

Final result :

 4 • (3x4 + 2)

 —————————————

      x2
