magnitude = sqrt(6^2+4^2)
= sqrt ( 36+16)
=sqrt (52) = 7.2
angle = tan^-1(6/4) = 56 degrees
Answer:
6+1x=y
Step-by-step explanation:
-just add 6 because you will only pay it once to enter the fair
-place x for the number of rides the person gets on and 1 next to it to multiply
- place Y at the end because we don't know how much the person spent
Answer:
4x - 5y = 0
Step-by-step explanation:
First off all you do it like this
4x - 5y = 23
4x - 5y - 23 = 23 - 23
4x - 5y - 23 = 0
Using the Poisson distribution, the probabilities are given as follows:
A. 0.0888 = 8.88%.
B. 0.1354 = 13.54%.
C. 0.8646 = 86.46%.
<h3>What is the Poisson distribution?</h3>
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:

The parameters are:
- x is the number of successes
- e = 2.71828 is the Euler number
is the mean in the given interval.
Item a:
10 hours, 2 calls per hour, hence the mean is given by:
.
The probability is P(X = 20), hence:


Item b:
1 hour, hence the mean is given by:

The probability is P(X = 0), hence:


Item c:
The probability is:
