Answer:
15p-9=5p-5
Step-by-step explanation:
i expanded the brackets I think this is correct if you wanted to expand it
Just use the coefficients for each variable and put it in a matrix. Is the second question set equal to something? Because then you would put it in place as the question mark. (Did the pic come through?)
So the 3x3 matrix is made up of the coefficients and then to augment the matrix, you add another column at the end with the solutions. Good luck!
8th term = 256/729
Step-by-step explanation:
Ratio = a2/a1
2/3 = a2/6 a 2=2/3*6 =12/3 =4 a2=4
1) 6* 2/3=4
2) 4*2/3=8/3
3) 8/3*2/3 = 16/9.......
The correct is b.
This is because, confidence interval is given by:
Confidence interval = p +/- error
In this case,
p = 18%
error = 3%
Therefore;
Confidence interval = 18+/-3 = [(18-3),(18+3)] = [15,21].
Therefore it will be true to say that the percentage of those who jog is between 15% and 21%.
