You find the probability of an event happening if you divide the number of times that event has actually happened in the experiment by the number of total events that has happened. If you want to find the probability of the used car, you have to know..
how many used cars were there? 15
how many cars were there? 40
Therefore, the probability of buying a used car is 15/40 or 3/8.
Answer:
v = -8
Step-by-step explanation:
First we would have to distribute the 8(-5 - 7v). To do this we would multiply 8 by -5 and 8 by -7v to get 
. After this, we would have to simplify like terms by subtracting 56v from -5v to get 
. We now have to get the variable on one side and to do that, we can add 40 to both sides to get 
. Finally to get the variable alone, we would have to divide both sides by -61 to get 
.

Hello :
sin(x) + cos(x) = √2(1/√2 sin(x) +1/√2 cos(x))
but : 1/√2 = cos(π/4) = sin(<span> π/4)
</span>sin(x) + cos(x) = √2( cos(π/4)sin(x) + sin( π/4) cos(x)) =√2<span>sin(x + π/4)
</span>because : cos(π/4)sin(x) + sin( π/4) cos(x)=sin(x + π/4) by identity :
sin(a+b) = sina cosb +cosa sinb
Answer:
√89
Step-by-step explanation:
√(x2 - x1)² + (y2 - y1)²
√(9 - 1)² + [-6 - (-1)]²
√(8)² + (-5)²
√64 + 25
√89
