Answer:
-16-72v
Step-by-step explanation:
-8*2 = -16
-8*9v = -72v
so, -16 + (-72v) -> -16-72v
See attached picture for solution:
C, planes are more likely to take off on time. .72 as a percent is 72%. Hence, a relatively high probability that the planes will take of on time.
Let S be the number of Brand S snowboards sold.
Let B be the number of Brand B snowboards sold.
309S + 489B = 4299
S + B = 11
S = 6 snowboards sold
B = 5 snowboards sold
