Answer:

304(pi) g

Step-by-step explanation:

First we find the volume of the hollow ball. Then we find the mass using the volume and density.

Let R = exterior radius = 3 cm

Let r = interior radius = 2 cm

volume = exterior volume - interior volume

volume = (4/3)(pi)R^3 - (4/3)(pi)r^3

volume = (4/3)(pi)(R^3 - r^3)

volume = (4/3)(pi)(3^3 - 2^3) cm^3

volume = (4/3)(pi)(27 - 8) cm^3

volume = (76/3)pi cm^3

Now we use the density and the volume to find the mass.

density = mass/volume

mass = density * volume

mass = 12 g/cm^3 * (76/3)pi cm^3

mass = 304(pi) g

Answer: 304(pi) g

Assuming the population is normally distributed, find the probability P(x>4.5) given the mean is 6 and the standard deviation

Kisachek [45]

Answer:

$P(x > 4.5)= 0.983943$

Step-by-step explanation:

Given

$\mu = 6$

$\sigma = 0.7$

Required

$P(x > 4.5)$

Start by calculating the z score

$z = \frac{x - \mu}{\sigma}$

So:

$z = \frac{4.5 - 6}{0.7}$

$z = \frac{-1.5}{0.7}$

$z = -2.143$

So, we have:

$P(x > 4.5)= 1 - P(x < 4.5)$

This gives:

$P(x > 4.5)= 1 - P(x < z)$

$P(x > 4.5)= 1 - P(x < -2.143)$

Using the z score probability table, we have:

$P(x > 4.5)= 1 - 0.016057$

$P(x > 4.5)= 0.983943$
