Answer:
Step-by-step explanation:
f(x) = 1/2 .2^x
We need to fill the table by putting values of x in the given f(x)
x = -2
f(x) = 1/2 .2^(-2)
f(x) = 1/2.1/2^2
f(x) = 1/2.1/4
f(x) = 1/8 = 0.125
y=0.125
x = -1
f(x) = 1/2 .2^(-1)
f(x) = 1/2.1/2^1
f(x) = 1/2.1/2
f(x) = 1/4 = 0.25
y=0.25
x = 0
f(x) = 1/2 .2^(0)
f(x) = 1/2. 1
f(x) = 1/2 = 0.5
y=0.5
x = 1
f(x) = 1/2 .2^(1)
f(x) = 1/2.2
f(x) = 1
y=1
x = 2
f(x) = 1/2 .2^(2)
f(x) = 1/2.4
f(x) = 2
y=2
x = 3
f(x) = 1/2 .2^(3)
f(x) = 1/2.8
f(x) = 4
y=4
Now we will plot these points. The graph is shown in the graph below.
Answer:
a)20$
b)46,1$
c)0,3336
d)No concerns
Step-by-step explanation:
A) To find expected difference of cost of medical care for dogs and cats we can simply subtract average costs of cats and dogs.
Expected difference will be 20$.
B) To find the standard deviation of that difference, we need to square deviations and add them and square root it again.
Expected difference will be 46,1$.
C)We need to find the Z value to find the probability of more expensive dogs than cats in a Vet vise.
Z value of the function is -0,434
From the Z table that you can find at the attachment. The probability is %33,36 or 0,3336
D) This is a subjective part. I don't have any concerns
