B•X. All u need to is b times x
Answer:
a) 
b) f(2) = 0.04462
c) f(1) = 0.01487
d) 
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 successes
e = 2.71828 is the Euler number
is the mean in the given interval.
In this question:
a. Write the appropriate Poisson probability function.
Considering
b. Compute f (2).
This is P(X = 2). So
So f(2) = 0.04462
c. Compute f (1).
This is P(X = 1). So
So f(1) = 0.01487.
d. Compute P(x≥2)
This is:
In which:
Then
So
Roughly 25 because she basically ate 4 slices
Answer:
A
Step-by-step explanation:
We can see that Function A's y coordinate doubles every time. The function A = f(x) = 5(2)^x. It is an exponential growth function, and therefore y can never be 0. This means that A does not have an x-intercept.
Function B is a rational function. x cannot be 0, since that would result in an undefined number. This also means that B does not have an x-intercept.
Answer:
minimum = $445
median = $565
standard deviation = $38
IQR = $48
Step-by-step explanation:
The minimum and the median are measures of location and are affected during addition (or subtraction) and multiplication (or division).
Satandard deviation and IQR (inter-quartile range), which are measures of dispersion, are affected by only multiplication (or division).
For the weight,
<em>minimum </em>= 920 pounds
<em>median </em>= 1160 pounds
<em>standard deviation</em> = 76 pounds
<em>IQR </em>= 96 pounds
For the price,
<em>minimum </em>= 0.50(920) - 15 = $445
<em>median </em>= 0.50(1160) - 15 = $565
<em>standard deviation</em> = 0.50(76) = $38............(<em>Subtraction discarded</em>)
<em>IQR </em>= 0.50(96) = $48........................................(<em>Subtraction discarded</em>)
