First, find the volume of the whole cube
Volume of cube = 4 x 4 x 4 = 64 cm³
The volume of sand is 25% of the volume of cube so,
Volume of sand = 25/100 x 64 = 16 cm³
Answer:
37
Step-by-step explanation:
Here, we have two different samples, hence, to obtain the confidence interval, we use the relation for the confidence interval for two sample means ;
(x1 - x2) ± Margin of error
Where, (x1 - x2) = point estimate of the sample mean, this is the difference in mean of the two samples.
From the question ;
x1 = 1150 ; x2 = 1113
Hence, the point estimate is : (1150 - 1113) = 37
It will have x and y switched
so (x,y) will become (y,x)
