Presumably,
. In that case,
(A)
The average rate of change over the interval
is
and over
, it's
(B)
, i.e. the average rate of change over the second interval is 25 times higher. That's to be expected;
is an exponential function. As
gets larger, the rate of change of
gets larger too.
Answer:
a) 0.1535
b) 0.4866
c) 0.8111
Step-by-step explanation:
The probability that the next call come within the next t minutes is:
According to this model,
a) the probability that a call in comes within 1/2 minutes is 
=0.1535
b) the probability that a call in comes within 2 minutes is 
=0.4866
c) the probability that a call in comes within 5 minutes is 
=0.8111
To solve this, you must subtract .56 from -1.64. Then divide that by -5.5x. So the answer is .4

Step-by-step explanation:
<u>Step 1: Define</u>
2x³y³ + 3xy - 3x³y³ + x²y - xy + 2x²y
x = -1
y = 2
<u>Step 2: Evaluate</u>
- Substitute: 2(-1)³(2)³ + 3(-1)(2) - 3(-1)³(2)³ + (-1)²(2) - (-1)(2) + 2(-1)²(2)
- Exponents: 2(-1)(8) + 3(-1)(2) - 3(-1)(8) + 1(2) - (-1)(2) + 2(1)(2)
- Multiply: -16 - 6 + 24 + 2 - (-2) + 4
- Simplify: -16 - 6 + 24 + 2 + 2 + 4
- Subtract: -22 + 24 + 2 + 2 + 4
- Add: 2 + 2 + 2 + 4
- Add: 4 + 2 + 4
- Add: 6 + 4
- Add: 10
