Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given size 'n' = 800
The population proportion 'p'=0.6
Let 'X' be the random variable of the binomial distribution
a) mean of the binomial distribution = n p = 800 ×0.6
μ = 480
b) variance of the binomial distribution
= n p q
= 800 X 0.6 ×0.4
σ² = 192
Standard deviation of the binomial distribution
σ =
Answer:
The cube with surface area of 0.3 sq. meters will exert more pressure.
Step-by-step explanation:
Pressure is given by
Since mass(m) and acceleration (a) for both the cubes are equal and the area varies, we will have to base our answer on the area.
In the formula for pressure, we can see that Pressure and Area are inverse of each other <em><u>(given mass * acceleration is constant, in this case).</u></em>
So the cube that will exert more pressure is the one with less surface area <u><em>(pressure and area are inverse of each other).</em></u>
Hence the cube with surface area of 0.3 sq. meters will exert more pressure.
