I’m guessing that the 5th percentile is app. 2 standard deviations which I think is right. In that case the 5th percentile will tend to wait for 212+2(24.7)= 261.4 (days?). Hope that helps!
Whats in the drop down menu??
Brenna and Raelle will need 10 adults. If it is 1:25 then you multiply both by 10, you get 10:250.
Hope this helped! :D
Let x be the 1st number
x + 9 be the second number
Equation:
x + x+9 = 171
Solution:
2x + 9 = 171
2x = 171 - 9
2x = 162
x = 81
x + 9 = 90
81 + 90 = 171
I think it’s Step C. Hope i’m right!
