Answer: f(0)=-1
Step-by-step explanation:
f(0) is a fancy way of saying the y value of the equation. the f(0) means that x=0. If you look at x=0, the graph is at y=-1. Therefore, f(0)=-1.
Answer:
17576000 different License plates are possible.
Step-by-step explanation:
Here we will use repetitive permutations.
First 3 digits of the license plates have letters from a to z and next 3 digits have numbers from 0 to 9.
Now, 26 letters ( a to z ) can take 3 positions with repetition in ways.
And 10 numbers ( 0 to 9 ) can take 3 positions with repetition in ways.
So the total number of license plates that can be made = = 17576 1000 = 17576000 plates.
Answer:
a. P(X = 2) = 0.2
b. P(X = 3) = 0.3
c. P(X > 2.5) = 0.7
d. P(X = 1) = 0.1
e. Mean = 3
f. Variance = 1
Step-by-step explanation:
As given,
Probability mass function (pmf) =
Now,
a. P(X = 2) = = 0.2
b. P(X = 3) = = 0.3
c. P(X > 2.5) = P(X = 3) + P(X = 4) = = 0.3 + 0.4 = 0.7
d. P(X = 1) = = 0.1
e. Mean = E(X) = = 0.1 + 0.4 + 0.9 + 1.6 = 3
f. Variance = E(X²) - [ E(X) ]² = - [3]²
= 0.1 + 0.8 + 2.7 + 6.4 - 9
= 10 - 9 = 1
∴ we get
a. P(X = 2) = 0.2
b. P(X = 3) = 0.3
c. P(X > 2.5) = 0.7
d. P(X = 1) = 0.1
e. Mean = 3
f. Variance = 1
