Answer:
maybe 6.24
sorry if wrong
Step-by-step explanation:
So, we know that 40 hours is $390 and 4 * 10 = 40, therefore, we just have to divide $390 by 4 to get $97.5, meaning that Zoe made $97.5 in 10 hours of work.
There are 6 pockets all together. You checked two of them and it wasn't
there. So you can forget about those 2, and now there are 4 pockets left.
The total number of ways for your next try is 4.
The number that will be successful is 1.
The probability of success on the next one is <em>1/4 = 25% .</em>
=======================================================
Another method of solution, somewhat more complex:
Total number of pockets = 6.
Amount of money missing = $10
First partial sum, i.e. sum of numbers
in the first part of the problem = 6 + 10 = 16.
Total number of pockets = 6
Current value of cargo pants on a fashion scale from 1 to 10 = -2.
Second partial sum = 6 - 2 = 4.
Probability = (second partial sum) / (first partial sum) = 4/16 = <em>25% </em>.
Answer:
4 mm
Step-by-step explanation:
The radius is half the diameter, so in this case the radius of each button is 4 mm.
