The following set of coordinates most specifically represents which figure? (−5, 6), (−1, 8), (3, 6), (−1, 4) (6 points) Paralle

Vladimir [108]

Answer:

Rhombus

Step-by-step explanation:

The given points are A(−5, 6), B(−1, 8), C(3, 6), D(−1, 4).

We use the distance formula to find the length of AB.

$|AB|=\sqrt{(-1--5)^2+(8-6)^2}$

$|AB|=\sqrt{16+4}$

$|AB|=\sqrt{20}$

The length of AD is

$|AD|=\sqrt{(-1--5)^2+(6-4)^2}$

$|AD|=\sqrt{16+4}$

$|AD|=\sqrt{20}$

The length of BC is:

$|BC|=\sqrt{(-1-3)^2+(8-6)^2}$

$|BC|=\sqrt{16+4}$

$|BC|=\sqrt{20}$

The length of CD is

$|CD|=\sqrt{(-1-3)^2+(6-4)^2}$

$|CD|=\sqrt{16+4}$

$|CD|=\sqrt{20}$

Since all sides are congruent the quadrilateral could be a rhombus or a square.

Slope of AB $=\frac{8-6}{-1--5}=\frac{1}{2}$

Slope of BC $=\frac{8-6}{-1-3}=-\frac{1}{2}$

Since the slopes of the adjacent sides are not negative reciprocals of each other, the quadrilateral cannot be a square. It is a rhombus

Suppose that X is a random variable that has a binomial uncertainty distribution with parameters n = 10 and π = 0.4. Calculate t

swat32

The numerical values of the mean and standard deviation are 4 and 1.55, respectively

<h3>The numerical value of the probability that x = 6. </h3>

The given parameters are:

n = 10

π = 0.4

The probability is then calculated as:

$P(x) = ^nC_x * \pi^x *(1-\pi)^{n-x}$

So, we have:

$P(6) = ^{10}C_6 * 0.4^6 *(1-0.4)^4$

Apply the combination formula

$P(6) = \frac{10!}{6!4!} * 0.4^6 *0.6^4$

So, we have:

$P(6) = 210 * 0.4^6 *0.6^4$

Evaluate

P(6) = 0.1115

Hence, the numerical value of the probability that x = 6 is 0.1115

<h3>The numerical values of the mean and standard deviation </h3>

The mean value is:

$\bar x = n\pi$

This gives

$\bar x = 10 * 0.4$

$\bar x = 4$

The standard deviation value is:

$\sigma = \sqrt{\bar x(1-\pi)$

This gives

$\sigma = \sqrt{4(1-0.4)$

$\sigma = 1.55$

Hence, the numerical values of the mean and standard deviation are 4 and 1.55, respectively

Are these number sets the same? 1857300 : 1857800

yaroslaw [1]

We are asked to determine if the number sets 1857300 and 1857800 are the same number sets. To answer this, we need to recall and define that number sets are a collection of distinct objects such as elements and numbers. The answer to this question is that these two sets are NOT the same, the first one contains "3" while the second one contains "8".
