Answer:
b=4√10
Step-by-step explanation:
AB²=AC²+BC²
14²=b²+6²
b²=14²-6²=160
b=√160=4√10

Answer:
a) 0.15
b) 0.2
c) 0.6
Step-by-step explanation:
We are given the following in the question:
A: Stopping at first signal
B: Stopping at second signal
P(A) = 0.35
P(B) = 0.55
Probability that he must stop at at least one of the two signals is 0.75
a) P(at both signals)
0.15 is the probability that motorist stops at both signals.
b) P(at the first signal but not at the second one)
0.2 is the probability that motorist stops at the first signal but not at the second one.
c) P(at exactly one signal)
0.6 is the probability that the motorist stops at exactly one signal.
Answer:
y=-2x/3+3
Explanation:
2x+3y=9
-2x -2x
3y=-2x+9
3y/3= -2x/3+9/3
y=-2x/3+3
Hope this helps!!
