Answer:
(1) 20%
Step-by-step explanation:
→ Find the difference in price
200 - 160 = 40
→ Divide difference by original price
40 ÷ 200 = 0.2
→ Multiply the answer by 100
0.2 × 100 = 20%
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:

Compute the probability of selecting a defective product:

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

Thus, the probability of selecting a non-defective part provided by supplier A is 0.807.
The first lot is (250 x 300) x 5 = 375,000
The second lot is (350 x 400) x 5 = 700,000
375,000 + 700,000 = $1,075,000
You need to use the "mean". -4 + -3 + -5= -12 ÷ by 3 = -4°. the answer is -4
