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.

How to solve 5h-2(3/2h+4)=10

trasher [3.6K]

Answer:

h = 9

Step-by-step explanation:

Solve for h:

5 h - 2 ((3 h)/2 + 4) = 10

Put each term in (3 h)/2 + 4 over the common denominator 2: (3 h)/2 + 4 = (3 h)/2 + 8/2:

5 h - 2(3 h)/2 + 8/2 = 10

(3 h)/2 + 8/2 = (3 h + 8)/2:

5 h - 2(3 h + 8)/2 = 10

(-2)/2 = (2 (-1))/2 = -1:

5 h + -1 (3 h + 8) = 10

-(3 h + 8) = -3 h - 8:

5 h + -3 h - 8 = 10

Grouping like terms, 5 h - 3 h - 8 = (5 h - 3 h) - 8:

(5 h - 3 h) - 8 = 10

5 h - 3 h = 2 h:

2 h - 8 = 10

Add 8 to both sides:

2 h + (8 - 8) = 8 + 10

8 - 8 = 0:

2 h = 10 + 8

10 + 8 = 18:

2 h = 18

Divide both sides of 2 h = 18 by 2:

(2 h)/2 = 18/2

2/2 = 1:

h = 18/2

The gcd of 18 and 2 is 2, so 18/2 = (2×9)/(2×1) = 2/2×9 = 9:

Answer: h = 9
