This doesn't make sense, as a triangle much equal 180, so it cannot have two angles bigger than 90, because this would mean it cannot be acute.

Answer:
$109
Step-by-step explanation:
<u>Formulas</u>
interest = (principal amount)(rate)(time)
<em>interest = (100)(0.09)(3) = $27</em>
total = principal amount + interest
<em>total = 100 + 9 = $127</em>
Answer:
B) 0.894
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given interval.
A local animal rescue organization receives an average of 0.55 rescue calls per hour.
This means that 
Probability that during a randomly selected hour, the organization will receive fewer than two calls.

In which
