When the bases are the same, you can combine the exponents.
x³ [x is where the base is]
For example:
x³ · y² = x³y² You can't simplify this anymore because they have different bases/variables
[when you multiply a variable with an exponent by a variable with an exponent, you add the exponents together] so:
x² · x³ =
[when you multiply a variable with an exponent by an exponent, you multiply the exponents together] so:
(x³)²=
Answer:
14
Step-by-step explanation:
starting at -18 you must add 5.4 until you reach 60
-18 + 5.4 = -12.6 once (1)
-12.6 + 5.4 = -7.2 twice (2)
-7.2 + 5.4 = -1.8 thrice (3)
-1.8 + 5.4 = 3.6 fourth (4)
3.6 + 5.4 = 9 fifth (5)
9 + 5.4 = 14.4 sixth (6)
14.4 + 5.4 = 19.8 seventh (7)
19.8 + 5.4 = 25.2 eighth (8)
25.2 + 5.4 = 30.6 ninth (9)
30.6 + 5.4 = 36 tenth (10)
36 + 5.4 = 41.4 eleventh (11)
41.4 + 5.4 = 46.8 twelth (12)
46.8 + 5.4 = 52.2 thirteenth (13)
52.2 + 5.4 = 57.6 fourteenth (14)
since 57.6 + 5.4 is over 60, we need to find the difference in how much we need
57.6 - 60 = -2.4
we need 2.4 so subtract by 5.4
5.4 - 2.4 = 3
therefore we should divide
= 14.444...
which means it goes into 60 (starting at -18) 14.444... repeating times
another way to find the answer is
add 18 + 60
18 + 60 = 78
78/5.4 = 14.444... repeating or 14
hope this helps:)
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
