Answer:
The distributive property.
Step-by-step explanation:
The distributive property is when you distribute a number to different numbers in a parentheses. For example...
2*x would be 2x, and 2*4 would be 8.
This can be solved using the formula for t test which is = x - mu over standard deviation divided by the square root of the number of samples. In this case, it is 1185 - 1200 over 70 divided by square root of 100 which give us a value of 2.14 which is equal to .9839 in area. Only rarely, just over one time in a hundred tries of 100 light bulbs, would the average life exceed 1200 hours.
To figure this out just multiply:
6 people had 3 servings = 6 x 3
6 x 3 = 18 There's your answer!
