Mathematics

barxatty [35]3 years ago

8000 BCE is the same as saying 8000 BC.  The term "BCE" means "Before Common Era" and "CE" means "Common Era".  The older terms of BC and AD means "Before Christ" and "Anno Dommoni" (Latin for "In the Year of Our Lord").  The change was made to make the terms secular.


The population was approximately 5 million people.

a coffee mug collection includes four red mugs, eight yellow mugs and two white mugs. What is the probability of selecting two w
Kruka [31]

Assuming that the selection process was done without replacement, the probability of selecting two white mugs without replacement is 1/28

<h2>Given data</h2>

Sample Space

Red mugs = 4

yellow mugs = 8

white mugs = 2

Sample Size = 4+8+2 = 14

We are going to assume the selection was done with out replacement

Hence the probability of selecting the first white mug is

<em>Pr(W1) = 2/8 = 1/4</em>

<em>The probability of selecting the second white mug is </em>

<em>Pr(W2) = 1/7</em>

<em />

Hence the probability of selecting  two white mugs one after another

= 1/4*1/7

=1/28

What is the equation of a line that passes<br> through the point (-1, -7) and has a slope of 5?
yulyashka [42]

Answer:

y=5x-2

or

5x-y-2=0

Step-by-step explanation:

  • Line is passing through the point (-1, -7)

  • \implies x_1 = -1,\: y_1=-7

  • Slope of line (m) = 5

  • Equation of line in point-slope form is given as: y- y_1=m(x-x_1)

  • Substituting the values of \implies x_1,\: y_1\: \&\: m in the above equation, we find:

  • y- (-7)=5[x-(-1)]

  • \implies  y+7=5[x+1]

  • \implies  y+7=5x+5

  • \implies  y=5x+5-7

  • \implies  y=5x-2

  • \implies  5x-y-2=0

Find the equation of the line with a slope of 1/5 that passes through the point (10,9).
IRINA_888 [86]

Answer:

The equation of the line with a slope of 1/5 that passes through the point (10,9) is:

  • y=\frac{1}{5}x+7

Step-by-step explanation:

Given

Slope = m = 1/5

Point (10, 9)

To Determine

An equation of the line with a slope of 1/5 that passes through the point (10,9).

We know that the point-slope form of the line equation is

y-y_1=m\left(x-x_1\right)

where

  • m is the slope of the line
  • (x₁, y₁) is the point

substituting the values m = 1/5 and the point (10, 9) in the equation

y-y_1=m\left(x-x_1\right)

y-9=\frac{1}{5}\left(x-10\right)

Add 9 to both sides

y-9+9=\frac{1}{5}\left(x-10\right)+9

y=\frac{1}{5}x-2+9

y=\frac{1}{5}x+7

Therefore, the equation of the line with a slope of 1/5 that passes through the point (10,9) is:

  • y=\frac{1}{5}x+7
