Options C, D, E. You should be able to simplify each one and realise that CDE does not equal the given equation
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.
Answer:
(2.3x104)x(1.5x10-2) = 3109.6
-5 + x = +
adding/subtracting numbers with same/different signs : if the signs are the same, whether both negative or positive, then the answer will contain the same sign.
Example : -2 + (-2) = -2-2 = -4 : both signs are negative, the sign stays negative.
5 + 5 = 10 : both signs are positive, the sign stays positive.
However, if the signs are different, u subtract the smallest number from the largest number and take the sign of the larger number.
Example : -2 + 5 = 3...I took 5 - 2..which is 3, and took the sign of the largest number (+)...so the answer is 3.
-5 + 2 = -3....I took 5 - 2 and got 3, but used the larger number sign (-) making the answer -3.
now for ur question....u can conclude that the sign of the other integer would have to be positive. As for the value, in order for the answer to be positive, the integer would have to be larger then + 5.
Example :
-5 + 6 = 1
-5 + 7 = 2
if u picked a positive number smaller then 5...
-5 + 4 = -1
-5 + 3 = -2
u would not get a positive result.
1. 5/8 = 15/24
1/4 = 6/24
2. 5/8 = 20/32
1/4 = 8/32
