Answer:
9.2
Step-by-step explanation:
you get 9.1651513... but it says round to the nearest 10th which would be 9.2
Answer:
14√2
Step-by-step explanation:
This is a 45-45-90 triangle
Because both of the angles are the same all sides, but the hypotonouse are the same
this means that the other length is 14 too
we can use a²+b²=c² to solve
14²+14²=c²
=
392=c²
√392=c
√392=14√2
The sum can be rewritten as y=4x, where y=f(x).
Now, we can rewrite the equation a x=y/4
Therefore, inv(f(x))=x/4
The components operate independently, so the probability of "total" system failure is the same as the product of each probability of component failure. That is, if
denotes the event that component
fails, then
The
are independent and identically distributed, so
for all
. So
72% of 25=18
25 there are
18 are good at math
7 aren't good at math
