That's the easily recognizable factored form of
the difference between two squares. Before
factoring, it was
x² - 16 .
Answer:
8
Step-by-step explanation:
Let the next number be x
'taking half the number to get the next number. is expressed as;
1/2 of 16 = x
x = 1/2 *16
x = 16/2
x = 8
hence the next number will be 8
Answer:
35
Step-by-step explanation:
Recall that the area under a probability curve is always 1.0. Here we have a probability distribution from 10.6 to 18.6 minutes, of length 10 minutes, so the height of the probability "curve" is 1.0 / 10, or 0.1.
To answer this question, find the area under the probability "curve" between 13.8 and 16.8 minutes. The difference between 13.8 and 16.8 is 3 units, so the desired probability is 3(0.1), or 0.30.
