$\text{Find the volume of the sphere}\\\\\text{We would use this equation:}\\\\V = \frac{4}{3}(3.14)r^3\\\\\text{Since we know our radius is 4, plug 4 into r and solve:}\\\\V = \frac{4}{3}(3.14)4^3\\\\V = \frac{4}{3}(3.14)64\\\\V = \frac{4}{3}(200.96)\\\\V = \frac{803.84}{3}\\\\V = 267.946\\\\\text{Round to the nearest hundredths}\\\\V=267.95\\\\\boxed{\text{Volume: 267.95 ft}^3}$

A standard chemistry examination administered nationally by the American Chemical Society has a mean of 500 and a standard devia

Maslowich

Let X be a random sample representing the score of a student in the American Chemical Society Examination.
P(450 < x < 500) = P((450 - 500)/(90/sqrt(25)) < z < (500 - 500)/(90/sqrt(25))) = P(-2.778 < z < 0) = P(z < 0) - P(z < -2.778) = P(z < 0) - [1 - P(z < 2.778)] = P(z < 0) + P(z < 2.778) - 1 = 0.5 + 0.99727 - 1 = 0.49727 = 49.7%
