Answer:

hope this answer will help u.

Step-by-step explanation:

<em>( 5x + 3y )² - ( 5x - 3y )² - 60xy</em>

<em>= ( 25x² + 30xy + 9y²) - ( 25x² - 30xy + 9y² ) - 60xy</em>

<em>= 25x² + 30xy +9y² - 25x² + 30xy - 9y² - 60xy</em>

<em>= 60xy - 60xy</em>

<em>= 0</em>

Suppose that Ayumi rolls a pair of fair six-sided dice. Let AAA be the event that the first die lands on 222 and BBB be the even
balu736 [363]

Answer:

1/6

1/6

1/36

Events A and B are independent

Step-by-step explanation:

Suppose:

A = event that first die lands on 2

B = event that second die lands on 2

Sample space:

Die 1 = 1,2,3,4,5,6

Die 2 = 1,2,3,4,5,6

Sample space of both die combined is attached below

Probability = (total number of required outcomes / total number of possible outcomes)

Probability that first die lands on 2:

P(A) = 1/6

Probability that second die lands on 2:

P(B) = 1/6

Probability of A and B:

P(A and B) = 1/6 × 1/6 = 1/36

Evebts A and B are independent because, the outcome of one event does not affect the occurrence of the other event.

Eric used to practice football for 90 minutes every day. Now, he practices 200% as many minutes as he used to. How many minutes
densk [106]
X/90 = 200/100  is/of = %/100
so cross multiply 90 and 200 and x and 100
giving you 18000 = 100x
divide both sides by 100
180=x
