Solution: We are given:

\mu=600, \sigma =120

We need to find the z value corresponding to probability 0.84, in order to find the how much money almost 84% of gamblers spent at casino.

Using the standard normal table, we have:

z(0.85) = 0.9945

Now we will use the z score formula to find the required amount:

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

0.9945=\frac{x-600}{120}

0.9945 \times 120 = x - 600

119.34 = x - 600

x = 600 + 119.34        

x = 719.34

x = 720 approximately

Therefore, almost 84% of gamblers spent more than $720 amount of money at this casino.

How do you solve 3/5×4 1/6?
Helen [10]
\frac{3}{5} × 4 \frac{1}{6}

First, convert 4\frac{1}{6} to an improper fraction. Use this rule: a \frac{b}{c} = \frac{ac+b}{c} / Your problem should look like: \frac{3}{5} × \frac{4x6+1}{6}
Second, simplify 4 × 6 to 24. / Your problem should look like: \frac{3}{5} × \frac{24+1}{6} 
Third, simplify 24 + 1 to 25. / Your problem should look like: \frac{3}{5} × \frac{25}{6}
Fourth, apply this rule: \frac{a}{b} × \frac{c}{d} = \frac{ac}{bd} / Your problem should look like: \frac{3x25}{5x6}
Fifth, simplify 3 × 25 to 75. / Your problem should look like: \frac{75}{5x6}
Sixth, simplify 5 × 6 to 30. / Your problem should look like: \frac{75}{30}
Seventh, simplify. / Your problem should look like: \frac{5}{2}
Eighth, convert to mixed fraction. / Your problem should look like: 2\frac{1}{2}

Answer: 2 \frac{1}{2}
