Answer:
(a) 0.0833 or 8.33%
(b) 0.40 or 40%
Step-by-step explanation:
Parts line one (n1) = 1,000 parts
Defects line one (d1) = 100 parts
Parts line two (n2) = 2,000 parts
Defects line two (d2) = 150 parts
Total number of parts (n) = 3,000 parts
a. Probability of a randomly selected part being defective:
The probability is 0.0833 or 8.33%
b. Probability of a part being produced by line one, given that it is defective:
The probability is 0.40 or 40%.
1. {26, 21, 28, 31, 9, 28, 16, 18, 21, 23, 29, 24, 19, 22, 25, 28}<br>

Answer:
368 / 16 = 23
Step-by-step explanation:
Add them all, then divide by how many numbers are in the data set.
Reflection across x-axis means multiplying the function value by -1.
Shifting upwards by 3 units means, adding 3 to the function value. So the resulting function after these two transformations will be:
Thus, option C gives the correct answer
Answer: 15 - (6 + 1) + 30 ÷ (3 × 2)
Step-by-step explanation:
The simplest way is just to [try check and revise]. Place parentheses on each two numbers and try.
However, there is a somewhat trick involved.
Normally, when a question asks for adding parentheses, the parentheses are normally placed on two numbers that don't usually operate together.
- For example, in this question, [15 - 6 + 1]. Normally, is should be 15-6 which is 9. Then 9+1 is 10. Also, usually when you add parentheses on -6+1, it will change signs into -(6-1). But, in this question, when we add parentheses, signs don't change. So it is -(6+1).
Hope this helps!! :)
Answer:
Triangle 1 - , hypotenuse = 16
Triangle 2 - , adjacent leg = 18
Triangle 3 - , opposite leg = 12
Step-by-step explanation:
Each triangle is solved by means of trigonometric relations:
Triangle 1 - , hypotenuse = 16
Triangle 2 - , adjacent leg = 18
Triangle 3 - , opposite leg = 12
