Answer:

n=3

Step-by-step explanation:

8n + 2 = 5n + 11

Subtract 5n from each side

8n-5n + 2 = 5n-5n + 11

3n+2 = 11

Subtract 2 from each side

3n+2-2 = 11-2

3n = 9

Divide by 3

3n/3 = 9/3

n =3

In the U.S. More male babies are born than females. In 1998 some 2,265,031 males were born and 2,287,419 females were born. Find

suter [353]

Answer: The empirical probability that the individual being born is a male = 0.498

Step-by-step explanation:

Given the following :

Number of males born =2,265,031

Number of females born = 2,287,419

Empirical probability is given as :

P( A) =( Number of possible outcomes of event A ÷ Total number of events)

Total number of events = (number of males born + number of females born)

Total number of events = (2,265,031 + 2,287,419) = 4552450

Probability(individual being born is a boy) =

(Number of males born ÷ Total number of children born)

=2265031÷(2265031+2287419) = 0.49754110424057

Therefore, the empirical probability that the individual being born is a male = 0.498

Ilya [14]

Answer:

12 meters

Step-by-step explanation:

Given That :

Length of ladder = 15m

Height of wall =. 9 m

Using Pythagoras rule :

Adjacent² = hypotenus² - opposite²

Adjacent² = 15² - 9²

Adjacent² = 225 - 81

Adjacent² = 144

Adjacent = sqrt(144)

Adjacent, x = 12
