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:

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

Serga [27]

Answer;

4 or more tubes or paint.

Step-by-step explanation:

54- 8.50x > 20

-54 -54

-8.50x > -34

now you have to divide by -8.50 on both sides to get x alone.

-8.50x/-8.50 > -34/-8.50

x=4
