A bag contains 2 red, 5 blue, and 3 green marbles. A marble is chosen at random. What is the probability of NOT choosing a red m
Lapatulllka [165]

Step-by-step explanation:

  1. Number of red = 2
  2. Number of blue = 5
  3. Number of green = 3
  • total number of marbles = 10
<h3>probability of not choosing a red marble = 1--choosing a red marble.</h3>

<u>Because</u><u> </u><u>probability</u><u> </u><u>is</u><u> </u><u>always</u><u> </u><u>one</u><u>(</u><u>1</u><u>)</u><u>.</u>

<em>Probability</em><em> </em><em>=</em>

<em>1 -  \frac{2}{10}</em>

<em>\frac{8}{10}</em>

<em>\frac{4}{5}</em>

<em>Is</em><em> </em><em>the</em><em> </em><em>probability</em><em> </em><em>of</em><em> </em><em>not</em><em> </em><em>choosing</em><em> </em><em>a</em><em> </em><em>red</em><em> </em><em>marble</em><em>.</em>

What is the measure of
sesenic [268]

Answer: C. 84

Step-by-step explanation:

In triangles ABD y BCD:

- AD=CD

- Angle BAD = angle BCD

- BD common side

THEN the triangles are equal because they have two sides and the angle opposite the longest side respectively equal.

CBD = ABD = 42 because the triangles ABD y BCD are equal

ABC = CBD+ABD = 42+42= 84

Help!!!! I really need help with this I don’t understand it!!!
Temka [501]

Answer:

  y = 5

Step-by-step explanation:

There are a number of ways to get there, but the short of it is that a horizontal line has the equation ...

  y = constant

The constant value must be chosen to match the y-value of points on the line. Here, that is 5. The equation of the line is ...

  y = 5

_____

<em>Another way</em>

You can write the equation in slope-intercept form if you know the slope and the y-intercept. The line crosses the y-axis at y = 5, so that is the value of the y-intercept.

The "rise" between the two points is 5 -5 = 0. The "run" between the two points is 5-0 = 5, so the slope is ...

  m = rise/run = 0/5 = 0

Then the slope-intercept equation is ...

  y = mx + b . . . . . where m is the slope and b is the y-intercept

  y = 0x +5

Simplifying, we get ...

  y = 5
