Sorry I was moving around taking the picture and my handwriting is sloppy. But I hope you understand how I got the answer
Answer:
f(x)=4/2x
i dont have no explanation
For this you need to use the reverse cosine function
Cos^-1 (.25)
75.6
It’ll be 20.
12+28+15+25+20=100
100/5= 20
Add all the numbers and then divide by the total amount of numbers there and that’s your answer
Answer: 200 bulbs will not be defective.
Step-by-step explanation:
The ratio of defective bulbs to good bulbs produced each day is 2 to 10. This ratio can also be expressed as 1 to 5 by reducing to lowest terms.
The total ratio is the sum of the proportions.
Total ratio = 1 + 5 = 6
This means that if n bulbs is produced, the number of defective bulbs would be
1/6 × n
The number of non defective would be
5/6 × n
Since n = 240, then the number of bulbs that will not be defective is
5/6 × 240 = 200 bulbs
