Answer:
x = 11
Step-by-step explanation:
Since this is a triangle, all interior angles add up to 180 so:
57 + 73 + 3x + 17 = 180
3x + 147 = 180
3x = 180 - 147
3x = 33
x = 11
We need to FOIL that out and then get it into standard form to see what our A, B, and C are. FOILing gives us
. If we move the 7 over by subtraction and set it equal to 0, we have
. In order to avoid a negative leading coefficient, we can change all the signs to get
so A = 1, B = 0, C = -18, first choice above.

Answer:option B is the correct answer
Step-by-step explanation:
The formula for poisson distribution is expressed as
P(x = r) = (e^- µ × µ^r)/r!
Where
µ represents the mean of the theoretical distribution.
r represents the number of successes of the event.
From the information given,
µ = 2.19
For the probability of no accidents on this section of highway during one day period, r = 0
Therefore,
P(x = 0) = (e^- 2.19 × 2.19^0)/0!
P(x = 0) = (e^- 2.19 × 1)/1
P(x = 0) = 0.112
