your final answer distributing or the by using the foil method will be 4m^2-12mn+9n^2
Answer:
d.
Step-by-step explanation:
tan Ф = opp. / adj. = 15/8
hyp = √(8²+15²) = √289 = 17
sin Ф = opp./ hyp = 15/ 17
The correct question is;
Ellen has a bag with 3 red marbles and 2 blue marbles in it. she is going to randomly draw a marble from the bag 300 times, putting the marble back in the bag after each draw. what is the best prediction for the number of times that ellen will draw a blue marble?
Answer:
120 times
Step-by-step explanation:
We are given;
Red Marbles = 3
Blue Marbles = 2
Thus;
Total Marbles = 3 + 2 = 5
Probability of of Blue Marbles;
P(B) = 2/5
Total number of Draws = 300
Hence, best prediction for the number of times that ellen will draw a blue marble = 300 x (2/5)
= 120
Thus, prediction is 120 Times that Ellen will Draw Blue Marbles
The answer is 7,500.
Hope that helped!!!
You can 14 rows of 5 chairs, which also means you can do 5 rows of 14. Or 7 rows of 10 or 10 rows of seven. That's all I'm getting that doesn't exceed the 20 row limit.
