 <span>If the positions are distinct, as in executive offices, then P(9, 5). 

P(9, 5) = 9!/(9 - 5)! = 15120 

If the positions are equivalent, such as seats in a legislative body, then C(9, 5). 

C(9, 5) = 9!/[(9 - 5)!(5!)] = 126</span>

Mike can stitch 7 shirts in 42 hours. he can stitch 1 shirt in how many hours, and in 1 hour he can stitch how much of a shirt.
podryga [215]

Answer:

Mike can stitch one shirt in 6 hours and in 1 hour he can stitch \frac{1}{6} (0.167) shirts.

Step-by-step explanation:

Mike can stitch 7 shirts in 42 hours

to calculate the time that he takes to make 1 shirt, we have to divide 42 by 7.

He can stitch 1 shirt in = \frac{42}{7} = 6 hours

Now we calculate the work done in one hour.

He can stitch in 1 hour = \frac{1}{6}  shirts or 0.167 shirts

Mike can stitch one shirt in 6 hours and in 1 hour he can stitch \frac{1}{6} shirts.
