Answer:

There are 9,000,000 seven-digit positive integers.

Explanation:

For the first digit, we have 9 choices: 1, 2, 3, 4, 5, 6, 7, 8, 9.

For each remaining digit, we have 10 choices: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

Each choice is independent of the others. So, the number of total 7-digit positive integers is the product of all the numbers of choices for each digit.

Since 0 cannot be put as the first digit, there are 9 choices for the first digit, and the next 6 digits have 10 choices. So, there are 9 × 10^6 = 9000,000 numbers.

3. A metal fabricating plant currently has five major pieces under contract each with a deadline for completion. Let X be the number of pieces completed by their deadlines, and suppose it's PMF p(x) is given by x 0 1 2 3 4 5 p(x) .05 .1 .15 .25 .35 .1 (a) Find and plot the CDF of X. (b) Use the CDF to find the probability that between one and four pieces, inclusive, are completed by their deadline

Answer:

a) The cumulative distribution function would be given by:

x 0 1 2 3 4 5

F(X) 0.05 0.15 0.30 0.55 0.9 1

b) $P(1 \leq X \leq 4) = F(4) -F(0) =0.9-0.05 = 0.85$

And replacing we got:

$P(1 \leq X \leq 4) =0.85$

Step-by-step explanation:

For this case we have the following probability distribution function given:

x 0 1 2 3 4 5

P(X) 0.05 0.1 0.15 0.25 0.35 0.1

We satisfy the conditions in order to have a probability distribution:

1) $\sum_(i=1)^n P(X_i)=1$

2) $P(X_i) \geq 0, i=1,2,..,n$

Part a

The cumulative distribution function would be given by:

x 0 1 2 3 4 5

F(X) 0.05 0.15 0.30 0.55 0.9 1

Part b

For this case we want to find this probability:

$P(1 \leq X \leq 4) = F(4) -F(0) =0.9-0.05 = 0.85$

And replacing we got:

$P(1 \leq X \leq 4) =0.85$
