169/2209 OR 7.22%

Step-by-step explanation:

[probability that both have the secret decoder ring]=(13/47)*(12/46)

[probability that both have the secret decoder ring]=(156/2162)

[probability that both have the secret decoder ring]=0.0722-------> 7.22%

the answer is 0.0722 (7.22%)

How do I find the absolute value
pychu [463]

Absolute value of function = - 9 / 3 .

The absolute value or modulus of a real number x, denoted by |x|, is the non-negative value of x without regard to its sign. Namely, |x|=x if x is a positive number, and |x|=-x if x is negative (in which case negating x makes -x positive) , and |0|=0.

For example, the absolute value of 3 is 3, and the absolute value of −3 is also 3. The absolute value of a number may be thought of as its distance from zero.

x ≥ 1.52 / 3 x - 1 = 2 / 3 x + 4⇒ -1 = 4 which is not possible .Now for all x ≤ 1.5- 2 /3 x + 1 = 2 / 3 x + 4⇒ 4 / 3 x = -3  x = - 9 /4 Hence absolute value = - 9 / 3 .

Convert the following units of time. a. 5 years to days b. 8 weeks to days c. 7 days to weeks d. 336 hours to seconds e. 12 hour
AysviL [449]

Answer:

A. 1,825 days

B. 56 days

C. 1 week

D.  1,209,600 seconds

E. 43,200 seconds

F. 2 hours

Step-by-step explanation:

A. 1 year = 365 days, then

5 years = 5\cdot 365 days = 1,825 days.

B. 1 week = 7 days, then

8 weeks = 8\cdot 7 days = 56 days.

C. 7 days = 1 week.

D. 1 hour = 3,600 seconds, then

336 hours = 336\cdot 3,600 seconds = 1,209,600 seconds.

E 12 hours = 12\cdot 3,600 seconds = 43,200 seconds.

F. 3,600 seconds = 1 hour, then

7,200 seconds = \dfrac{7,200}{3,600} hours = 2 hours.

A local library claims it has 2.73x103 books. If there are 42 people in the building, how many books per capita are there?
Marizza181 [45]

Answer:

63 books per capita in the library

<em></em>

Step-by-step explanation:

Given

Books = 2.73 * 10^3

People = 43

Required

Determine the book per capita

To do this, we simply divide the number of books by number of person;

Average = \frac{Books}{People}

Average = \frac{2.73 * 10^3}{43}

Average = \frac{2.73 * 1000}{43}

Average = \frac{2730}{43}

Average = 63.488372093

Average = 63 (Approximated)

Hence;

<em>There are 63 books per capita in the library</em>
