What does a lake with a zero elevation mean
Yanka [14]

Answer:

Zero-elevation surface is a vertical datum that is used to describe a surface, such as that of a planet. The value of this datum is usually adopted by statute. This elevation is used, for example, to build a texture map from an agreed surface, such as a spheroid with dimensions defined by a mean surface gravity.

A spinner is divided into six equal-sized sectors labeled 1 through 6. Dwayne spins this spinner 12 times. Let X
slavikrds [6]

Answer:

b) μ = 2 and σ = 1.29

Step-by-step explanation:

<u><em>Step(i):-</em></u>

<em>Given that the A spinner is divided into six equal-sized sectors labelled 1 through 6</em>

<em>Given that the probability of labelled '1'</em>

<em>                       </em>p = \frac{1}{6} =0.16

<em>                      q = 1-p =  1- 0.16 = 0.84</em>

Let 'X' be a random variable in binomial distribution

The mean of the binomial distribution

      μ = n p

     μ  =  12 (\frac{1}{6} ) = 2  

<em>The mean of the binomial distribution  = 2</em>

<u><em>Step(ii):-</em></u>

The standard deviation of X

                σ = \sqrt{npq}

               σ = \sqrt{12(0.16)(0.84}

                  σ = 1.269

<em>The standard deviation of the binomial distribution</em>

<em>                </em> σ = 1.269

<u><em></em></u>

A jar contains 6 red marbles numbered 1 to 6 and 4 blue marbles numbered 1 to 4. A marble is drawn at random from the jar. Find
svetoff [14.1K]

Answer:

Step-by-step explanation:

A

The marble is red. There are 6 red marbles out of ten. So the answer is

6/10 = 0.60

B

Red: 1 3 5

Blue: 1 3

So there are 5 ways that you can draw an odd number. The problem is that they are not evenly distributed.

Red: 1/2 * 3/6 = 1/4 = 0.25

Blue: 1/2 * 2/4 = 0.25

Red + blue = 1/4 + 1/4 = 1/2

You could have gotten 1/2 by taking 5/10 but that won't always work.

which expression represents purely real numbers and which expression represents non-real complex number?​
Ray Of Light [21]

Incomplete question. However, I provided some explanation about non-real complex numbers.

<u>Explanation</u>:

In Mathematics, the term complex numbers (non-real complex numbers) in simple terms refers to numbers that containing an imaginary addition to it.

For example, the numbers 3i, 3 + 5i, 3i/4 are <u>non-real numbers</u> because of the addition of an imaginary part which is denoted by 'i'.

While real numbers, on the other hand, are numbers that do not include an imaginary part; they stand on their own, such as whole numbers 0, 1, 2, 3, etc, rational numbers like 3/4, etc.
