A contractor records all of the bedroom areas, in square feet, of a five-bedroom house as: 100, 100, 120, 120, 180 What is the v

The variance is the total of the squared distances of the given data from the mean.

This can be calculated through the equation,

  σ² = summation of X² / N - μ²

where σ² is the variance X's are the data, N is the number of terms, and μ is the mean.

summation of X² = 100² + 100² + 120² + 120² + 180² = 81200
N = 5
  μ = (100 + 100 + 120 + 120 + 180) / 5
μ = 124

Substituting these values to the equation for variance,

  σ² = (81200/5) - 124² = 864

Thus, the variance is equal to 864.

the volume of hemisphere is 1527.4cm^3.find the radius of the hemisphere to the nearest whole whole number.(take π to be 22/7)

skelet666 [1.2K]

Answer:

radius of the hemisphere = 9 cm approx

Step-by-step explanation:

Volume of hemisphere = $\frac{2}{3} \pi r^{3}$

1527.4 = $\frac{2}{3} * \frac{22}{7} * r^{3}$

$\frac{7*15274*3}{2*22*10}$ = $r^{3}$

$\frac{320754}{440}$ = $r^{3}$

$r^{3}$ = 729

r = $\sqrt[3]{729}$

r = 9 cm approx.
