Answer:
<h3>
EVEN</h3>
Step-by-step explanation:
the product of odd numbers is always odd
the product of even numbers is always even
the product of odd number and even one is always even
the <u>sum of two odd </u>numbers is always <u>even</u>
and the sum of two even numbers is always even
so if x is even number we have:
x²=x•x - even number
x⁴=x²•x² - even number
3x²=3•x² - even number
y = x⁴+3x² <u>- even number</u>
and if x is odd number we have:
x²=x•x - odd number
x⁴=x²•x² - odd number
3x²=3•x² - odd number
y = x⁴+3x² <u>- even number</u>
Answer:
randomly choosing a marble from a bag, replacing it, and choosing again
rolling a number cube, rolling again, and trying to match the first roll
Explanation:
In an independent event, getting a certain outcome once does not change the probability of getting the same outcome again.
The second option (about the coins) is NOT independent because if you pull out a dime on your first try, there are fewer dimes in your pocket and you are less likely to pull out a dime the second try. The third option (about drawing a number) is also NOT independent for the same reason: you don't put the number back into the hat after drawing it out, so there's fewer numbers the second time and the probability is different.
