126:399 is one of the ratios to use and 42:133.
Answer:
1,726 cm
Step-by-step explanation:
it boils down to this equation:
2(19×29)+2(19×6.4)+2(29×6.5)
bc if you look closely, it's just each side twice (hope that makes sense)
then you work down from there
2(551)+2(123.5)+2(188.5)
1,102+259+337
1,726
In 7500 iPhones, 18 were found defective.
18 of 7500 is 0.24%
0.24% of iPhones were defective.
Using the information above:
In a sample of 60000 new iPhones, 144 would be found defective.
144 of 60000 is 0.24%
Answer: 144 defective iPhones would be expected in a sample of 60,000.
Hope this helps! Good luck. :-)
