2b + 6
2(b+3)
if you distribute 2(b+3), you get 2b+6
Answer:
It's the 2nd one
Step-by-step explanation:
To find the number of yellow marbles, you would do the number of blue marbles plus 6 marbles.
So in this case, let's say n was equal to the number of blue balls, the equation would be n+(n+6)=24.
What if n was equal to the number of yellow balls. The equation would be n+(n-6)=24.
Hope this made sense, let me know if you are still confused.
Answer:
3+4
you can get positive

Step-by-step explanation:
Answer:
SE = 0.025
Step-by-step explanation:
We are given;
Sample mean; x¯ = 14.52
Sample standard deviation; s = 0.075
Sample size; n = 9
Now,formula for standard error of sample mean is;
SE = s/√n
SE = 0.075/√9
SE = 0.075/3
SE = 0.025
