Positive because two negative signs would make it a positive. The answer would be 7. If you had a positive 3 and a negative 4 it would make it negative (bigger number) If you had a positive 4 and a negative 3, it would be positive (bigger number yet again)
If I'm wrong I'm sorry XD I haven't gone this in years.
Answer:
or 80.25%
Step-by-step explanation:
Number of blue Marbles = 4
Number of Red Marbles = 5
Total Number of marbles =4+5=9
In the experiment, two marbles are chosen one after the other with replacement.
The possible outcomes are: BB, BR, RB and RR
The probability of getting at least 1 red
=P(BR or RB or RR)
=P(BR)+P(RB)+P(RR)
Expressed as a percentage, we have:
The probability of getting at least 1 red is 80.25%.
I think this is the answer
Right angle: 90 degrees
Straight angle: 180 degrees
Acute angle: 80 degrees
Obtuse angle: 100 degrees
Hope this helps :)
The Slope is 0 (there is no incline or decline therefore there is no slope)
