1) At 95% Confidence interval the critical value is z0.025= 1.96 Margin of error = 0.02 Or, z0.025* sqrt(p(1 - p)/n) = 0.02 Or, 1.96 * sqr

Answer:
80cm^2
Step-by-step explanation:
20*5=100
10*2=20
100-20=80
Since 
(density = mass/volume), we can get the mass/weight of the liquid by integrating the density 
over the interior of the tank. This is done with the integral
which is more readily computed in cylindrical coordinates as
Answer: 74.9 millimeters
Step-by-step explanation:
From the question, a photo of a beetle in a science book was.increased to 535% as large as its actual size and the beetle.has a actual size of 14 millimeters,
The size of the beetle on the photo will be 535% of 14 millimeters. This will be:
= 535% of 14
= 535/100 × 14
= 5.35 × 14
= 74.9 millimeters
