Answer:

sqrt(-8x+5)

Step-by-step explanation:

(5-8x)

-----------------

sqrt(-8x+5)

We need to rationalize the denominator

(5-8x)               sqrt(-8x+5)

----------------- * ---------------

sqrt(-8x-5)         sqrt(-8x+5)

(5-8x)               sqrt(-8x+5)

----------------- * ---------------

(-8x+5)

The first term cancels

Answer:

Second option

Step-by-step explanation:

The radical represents the square root, i.e power ½

(5 - 8x) ÷ (5 - 8x)^½

(5 - 8x)^(1-½)

(5 - 8x)^½

(-8x + 5)^½ (just a rearrangement)

The distribution of the amount of money spent by first-time gamblers at a major casino in las vegas is approximately normal in s
Lostsunrise [7]

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.
