Suppose that 10% of all steel shafts produced by a certain process are nonconforming but can be reworked (rather than having to

be scrapped). Consider a random sample of 200 shafts, and let X denote the number among these that are nonconforming and can be reworked.
(a) What is the (approximate) probability that X is at most 30?

(b) What is the (approximate) probability that X is less than 30?

(c) What is the (approximate) probability that X is between 15 and 25 (inclusive)?

Answer:

0.9905,0.9837,0.8066

Step-by-step explanation:

Given that 10%  of all steel shafts produced by a certain process are nonconforming but can be reworked (rather than having to be scrapped).

Each shaft is independent of the other and probability for non conforming is the same for each trial.

Hence X the among these that are nonconforming and can be reworked. is Bin with n =200 and p = 0.10

a) P(X\leq 30) = 0.9905

b) P(X

c) P(15\leq x\leq 25)\\= F(25)-F(14)\\= 0.8995-0.0929\\= 0.8066

The table below shows temperatures of a mixture in a chemistry experiment over 5 days.
balandron [24]

Step-by-step explanation:

3.4 and -3.4 both have the same absolute value.

It appears that these days would be Tuesday and Friday based on the data you have provided.

Absolute Value

Absolute value is based on the numbers alone, and not the sign in front of them (negative or positive)

When considering absolute value, ignore positive and negative signs. Absolute value is indicated by terms inside of | | straight vertical lines

Example:

|3.4| = 3.4

|-3.4| = 3.4
