Find the GCF, then factor it out. Finally, simplify each term in the parentheses.
5x + 2x3 + 8x2


Answer:
15.87%
Step-by-step explanation:
Notice that the mean of 0.35 inches with a standard deviation of 0.01 gives you when you add (to the right of the distribution), exactly 0.36. Since you want to find the probability (or percentage) of the bolts that have diameter LARGER than 0.36 in, that means you want to estimate the area under the Normal distribution curve from 0.36 to the right). See attached image.
We can use the tables of Z distribution for that, or the standard normal tables:
P(x>0.36) = P(z>(0.36-0.35)/0.01) = P(Z>1) = 0.1587 = 15.87%
1/10 is equal to 0.10. Multiply their total tables (200) by the percent (10% aka 0.10), and you get 20. Hope this helps.
