Two positive, consecutive, odd integers have a product of 143. set up an equation to then solve for the integers.

mixer [17]

Answer:

Step-by-step explanation:

Let (2n-1) and (2n+1) be the consecutive, odd numbers.

(2n-1)(2n+1) = 143

4n² - 1 = 143

4n² = 144

n² = 36

n = 6

2n-1 = 11

2n+1 = 13

The numbers are 11 and 13.

The mail arrival time to a department has a uniform distribution over 5 to 45 minutes. What is the probability that the mail arr

VashaNatasha [74]

Answer:

0.5

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X higher than x is given by the following formula.

$P(X > x) = \frac{b - x}{b-a}$

The mail arrival time to a department has a uniform distribution over 5 to 45 minutes.

This means that $a = 5, b = 45$ .

What is the probability that the mail arrival time is more than 25 minutes on a given day?

$P(X > 25) = \frac{45 - 25}{45 - 5} = 0.5$

So the probability that the mail arrival time is more than 25 minutes on a given day is 0.5.
