The expression would be 2.98 * 10 to the -7 power? Please tell me if I'm wrong.
4-1.175=2.825
There was 2.825 liters left in the tank.
Hope this helps.
Answer:
The probability table is shown below.
A Poisson distribution can be used to approximate the model of the number of hurricanes each season.
Step-by-step explanation:
(a)
The formula to compute the probability of an event <em>E</em> is:

Use this formula to compute the probabilities of 0 - 8 hurricanes each season.
The table for the probabilities is shown below.
(b)
Compute the mean number of hurricanes per season as follows:

If the variable <em>X</em> follows a Poisson distribution with parameter <em>λ</em> = 7.56 then the probability function is:

Compute the probability of <em>X</em> = 0 as follows:

Compute the probability of <em>X</em> = 1 as follows:

Compute the probabilities for the rest of the values of <em>X</em> in the similar way.
The probabilities are shown in the table.
On comparing the two probability tables, it can be seen that the Poisson distribution can be used to approximate the distribution of the number of hurricanes each season. This is because for every value of <em>X</em> the Poisson probability is approximately equal to the empirical probability.
Y=2x+4
To graph this linear function, put a point on (0,4) since 4 is the y-intercept. From that point, place the next point two units up and one unit over from the y-intercept since the slope is 2 or 2/1.
5x+x=42
X=7
The daughter is 7
Check work 7 times 5 is 35, 35 plus 7 is 42
