Answer:
0.1175 or 11.75%
Step-by-step explanation:
If the new machine is 3 times more productive than the old machine, then 75% of widgets are produced by the new machine with a defective rate of 8%, while 25% of widgets are produced by the old machine with a defective rate of 23%.
The probability that a randomly chosen widget produced by the company is defective is given by:

The probability is 0.1175 or 11.75%.
A/4 + 2 = 6....subtract 2 from both sides
A/4 = 6 - 2
A/4 = 4...multiply both sides by 4, eliminating the 4 on the left side
A = 4 * 4
A = 16
-4 = r/20....multiply both sides by 20, eliminating the 20 on the right side
-4 * 20 = r
-80 = r
0.7 can be turned into a fraction which can be 70/100 and 3/4 can be turned into 75/100 so 3/4 would be greater
Each exterior angle = (360° / number of sides)
Each exterior angle = 3.6°
Answer:
Step-by-step explanation:
Let x represent the speed of the slower plane. The faster plane's speed is then x+40. The sum of speeds is ...
x + (x+40) = 1180
2x = 1140 . . . . subtract 40
x = 570 . . . . . .divide by 2
x+40 = 610 . . . . the speed of the faster plane
The two speeds are 570 mph and 610 mph.
