8a - 1 + 0.5b = 8(1/4) - 1 + 0.5(10)
= 2 - 1 + 5
= 1 + 5
= 6
_Brainliest if helped!
1 over 64
8^2 = 64 , 8^-2 = 1/(8^2) = 1/64
You will not be able to find the mean from a histogram. The reason is that histograms are special bar graphs that graph data that fall into a range/interval. For example, you would create bars based on what data might fall into 0-9, 10-19, 20-29, 30-39, etc...
With intervals, we do not know the exact data points. They just fall into a range.
I think answer should be 20 I think I’m not 100 percent sure so please give me brainlest let me know if it’s correct or not okay thanks bye bye
