The distribution of the amount of money spent by first-time gamblers at a major casino in Las Vegas is approximately normal in s
Leya [2.2K]

Answer:

$720

Step-by-step explanation:

Given :

Mean, m = 600

Standard deviation, s = 120

Z = (x - m) / s

P(Z > x) = 84%

P(Z > x) = 0.84

Zscore corresponding to P(Z > x) = 0.84 will be -0.994

Hence,

-0.994 = (x - 600) / 120

120 * -0.994 = x - 600

119.28 = x - 600

119.28 + 600 = x

719.28 = x

Hence,

X = $720

IRISSAK [1]

Answer:

In the complex number 4 + 2i, 4 is the <em>real </em>part. In the complex number 4 + 2i, 2 is the <em>imaginary </em>part.

Step-by-step explanation:

The two parts of the complex number are called the <em>real</em> part and the <em>imaginary</em> part. The imaginary part is identified by its multiplier of <em>i</em>.

In the given number, the 2 is multiplied by i, so 2 is the imaginary part. The other part, 4, is the real part.
