What Ln(z) is answer????!!

dimaraw [331]

Write z in exponential form:

$z=1-i=\sqrt2 e^{-i\frac\pi4}$

Then taking the logarithm, we get

$\mathrm{Ln}(z)=\ln(\sqrt2) + \ln e^{-i\frac\pi4} = \boxed{\ln(\sqrt2)-\dfrac\pi4i}$

so a is the correct answer.

A random variable r is normally distributed with a mean of 7 and a standard deviation of 1.5. Find the value of w so that P (8.8

a_sh-v [17]

Answer:

The answer is explained below

Step-by-step explanation:

Given that:

mean (μ) = 7 and standard deviation (σ) = 1.5.

The z score is used in statistic used to measure the number of standard deviation by which the raw score is above or below the mean value. It is given by:

$z=\frac{x-\mu}{\sigma}, where\ x\ is\ the \ raw\ score$

To find the Probability that x < 8.8, we first find the z score using:

$z = \frac{x-\mu}{\sigma}=\frac{8.8-7}{1.5}=1.2$

From the z tables, P(x < 8.8) = P(z < 1.2) = 0.8849 = 88.49%

A building casts a shadow that is 420 meters long. At the same time, a person who is 2 meters tall casts a shadow that is 24 met

Westkost [7]

Answer:

35 Meters

Step-by-step explanation:

Ratio is 12

What I mean by that is 2 turns into 24 because you multiply 12 to it. Same thing for 420, except for the fact that you divide it (working backwards). So 420 divided by 12 equals 35:) Enjoy your day
