Based on the information given, it should be noted that the mean and standard deviation of Y will be 0.4899 and 0.699 respectively.

<h3>Calculating the mean.</h3>

Based on the information given, it should be noted that the probability distribution for y will be:

Y 0 1. 2

Probability 0.63. 0.25. 0.12

The mean of Y will be:

= (0 × 0.63) + (1 × 0.25) + (2 × 0.12)

= 0 + 0.25 + 0.25

= 0.49

The variance will be 0.4899. Therefore, the standard deviation will be:

= ✓0.4899

= 0.699

State if each triangle is a right triangle.

Kitty [74]

Answer:

No, It is not a right triangle

Step-by-step explanation:

For it to be a right triangle, the hypotenuse would be equal to the sum of the legs when squared.

Use the pythagorean theorem-

8^2+12^2=15^2

64+144=225

208=225

Since they aren't equal, it is not a right triangle.

Write an equation in slope-intercept form for the line passing through the pair of points.

damaskus [11]

Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line<em>:</em>

$y=mx+b$

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

==========================================

We have the points (-1, 2) and (4, -3).

Calculate the slope:

$m=\dfrac{-3-2}{4-(-1)}=\dfrac{-5}{5}=-1$

Put the value of the slope an the coordinates of the point 9-1, 2) to the equation of a line:

$2=(-1)(-1)+b$

$2=1+b$ <em>subtract 1 from both sides</em>

$1=b\to b=1$

Finally:

$y=-x+1$

What is the value of log 13? Use a calculator. Round your answer to the nearest tenth. 0.1 0.3 1.1 2.6

Kazeer [188]

A logarithm is defined as a power to which a number must be raused to in order to get another number. For example,
$log_{2}(8) = 3$
This is because
${2}^{3} = 8$
So if we have
$log(13) = x$
We have to determine what number must 10 be raised to in order to give 13 so we have
$log(13) = 1.11394 \\ {10}^{1.11394} = 13$
