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%
F(x) = 2x² + 7x - 5
g(x) = -8x² - 3x + 5
g(x) + f(x) = -8x² - 3x + 5 + 2x² + 7x - 5 = - 6x² + 4x
Answer: -6x² + 4x
Answer:
c
Step-by-step explanation:
Answer: $88.90
Step-by-step explanation:
Let her initial deposit be represented by x.
Based on the information given, in the question, an equation can be formed as:
x + $25.50 + $45.25 - $15.15 - $28.65 = $115.85
x + $70.75 - $43.80 = $115.85
x = $115.85 + $43.80 - $70.75
x = $88.90
The initial deposit is $88.90
