Two different suppliers, A and B, provide a manufacturer with the same part. All supplies of this part are kept in a large bin.
koban [17]

Answer:

The probability of selecting a non-defective part provided by supplier A is 0.807.

Step-by-step explanation:

Let <em>A</em> = a part is supplied by supplier A, <em>B</em> = a part is supplied by supplier B and <em>D</em> = a part is defective.

<u>Given</u>:

P (D|A) = 0.05, P(D|B) = 0.09

A supplies four times as many parts as B, i.e. n (A) = 4 and n (B) = 1.

Then the probability of event <em>A</em> and <em>B</em> is:

P(A)=\frac{n(A)}{n(A)+N(B)}= \frac{4}{4+1}=0.80\\P(B)\frac{n(B)}{n(A)+N(B)}= \frac{1}{4+1}=0.20

Compute the probability of selecting a defective product:

P(D)=P(D|A)P(A)+P(D|B)P(B)\\=(0.05\times0.80)+(0.09\times0.20)\\=0.058

The probability of selecting a non-defective part provided by supplier A is:

P(A|D')=\frac{P(D'|A)P(A)}{P(D')} = \frac{(1-P(D|A))P(A)}{1-P(D)}\\=\frac{(1-0.05)\times0.80}{(1-0.058)}\\ =0.80679\\\approx0.807

Thus, the probability of selecting a non-defective part provided by supplier A is 0.807.

Given: m∠LOI=38°, m∠JOP=84°
Romashka-Z-Leto [24]

Answer:

The measure of angle JKP is m

Step-by-step explanation:

step 1

we know that

The measure of the arc is equal to the measure of its central angle

so

arc\ JP=m

and

arc\ IL=m

step 2

Find the measure of the angle JKP

we know that

The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite.

m

substitute the values

m
