Answer:
12 cubes
Step-by-step explanation:
If the total volume of the box is 24 cm³ and the volume of each cube is 1 cm³ then that means that 24 total cubes can fit perfectly inside the box. Since there can only be two layers of cubes then we simply need to divide the total amount of cubes that will fit in the box by 2 to find the number of cubes in each layer...
24 / 2 = 12 cubes
Finally, we can see that each layer within the box will contain 12 cubes

Answer: 
Step-by-step explanation:
The confidence interval for population mean is given by :-
, where 
= Population standard deviation.
n= sample size
= Sample mean
z* = Critical z-value .
Given : 
n= 49
Two-tailed critical value for 95% confidence interval = 
Then, the 95% confidence interval would be :-
Hence, the 95% confidence interval for estimating the population mean 
:
24/64= 3/8
so the ratio is 3 to 8
