Answer:
is this the right question please??
Answer:
x>-5/7
Step-by-step explanation:
Because our dividing 5 by a negative 7 the symbol flips
I think the answer is x= 11 but im not sure <span />
1/4 c + 3d
c=6 d=7
1/4 (6) + 3(7)
1.5+ 3(7)
1.5+ 21
22.5
I believe this problem has the following table for long
distance call:
0-1 minutes 2-5 minutes 6+ minutes
Long distance 170 120 10
To solve this problem, let us first recall what
probability means:
Probability = number of successful event / number of
total events
In this case, an event is considered to be successful
when the long distance call is not 6+ minutes long. Therefore:
number of successful event = 170 + 120 = 290
Now the number of total events is the sum of all number
of calls, hence,
number of total events = 170 + 120 + 10
number of total events = 300
Probability that the call is not 6+ minutes long is
therefore:
Probability = 290 / 300
Probability = 0.9667
or
Probability = 96.67%
