Answer:

x = 14.6

ZA = 30.8

ZB = 33.2

Step-by-step explanation:

First, solve x: (knowing all angles of a triangle are 180º)

116º + (2x + 4)º + (3x-13)º = 180º

116 + 2x + 4 + 3x - 13 = 180

2x + 3x = 180 + 13 - 4 - 116

5x = 73

x = 73/5 = 14.6

ZA = 3*14.6 - 13 = 30.8

ZB = 2*14.6 + 4 =33.2

Test:

116º + 33.2º + 30.8º = 180º

A jar has 20 marbles: 3 green, 12 blue, 5 red.
nadezda [96]

Probability is defined as the <u>likelihood or the certainty</u> that an event is going to<u> occur or happen.</u>

The probability of randomly choosing a red and then a green marble is 3/76.

The total number of marbles = 20

The number of green marbles= 3

The number of blue marbles = 12

The number of red marbles = 5

<u>The probability of choosing a red marble</u> = Number of red marbles / Total number of marbles

= 5/20

<u>In simplest fraction form</u> = \frac{1}{4}

We are told in the question that you keep the red marble you choose, So this means the <u>total number of marbles</u> left reduces to 19

<u>The probability of choosing a green marble is</u> =  Number of green marbles / New total number of marbles

= 3/19

Therefore, <u><em>the probability of randomly choosing a red and then a green marble is </em></u>

P (Red) x P(Green)

= 1/4  x 3/19

= 3/76
