The quadratic equation that has a root of 6 and 2 is x^2 - 8x + 12 = 0

<h3>How to determine the quadratic equation?</h3>

The roots are given as:

x = 6 and x = 2

Rewrite as:

x - 6 = 0 and x - 2 = 0

Multiply both equations

(x - 6)(x - 2) = 0 * 0

Evaluate the product

x^2 - 6x - 2x + 12 = 0

Evaluate the difference

x^2 - 8x + 12 = 0

Hence, the equation that has a root of 6 and 2 is x^2 - 8x + 12 = 0

Give an example that shows why you need to reverse the sign when dividing or multiplying an inequality by a negative number.
AnnZ [28]

Answer:

2 < 3 ⇒ -2 > -3

Step-by-step explanation:

∵ 2 < 3

If we divide each side by -1

∴ -2 < -3 but it's not true

∴ we must reverse the sign of inequality

∴ -2 > -3

similar:

∵ 25 > 20

If we divide each side by -5

∴ -5 > -4 it's not true

∴ we must reverse the sign of inequality

∴ -5 < -4

kherson [118]

Answer:

3.6% of the ball bearings will have diameters of 20.27 mm or more.

Step-by-step explanation:

We can calculate this proportion using the z-score.

We have a normal distribution with mean 20.00 mm and standard deviation of 0.150 mm.

The value for X is 20.27 mm.

Then, the z-score and its associated probability are:

z=\dfrac{X-\mu}{\sigma}=\dfrac{20.27-20}{0.15}=\dfrac{0.27}{0.15}=1.8\\\\\\P(X>20.27)=P(z>1.8)=0.036=3.6\%
