A^2 + 31 = 155 - I squared each of b and c for those numbers
a^2 = 155 - 31
a^2 = 124
a = 4 * sqrt(31)
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
.
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> = 
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
=

Answer:
g(-2) = -19
g(0) = -5
g(3) = -14
Step-by-step explanation:
- g(-2)= -2(-2)2 + 3(-2) - 5
-
9(-2)= -2(4) - 6-5
-
g(-2)= - 8 - 11
- g(-2) = -19
<u>This is a quadratic function and its form is:</u>
<u>Calculation of g(0) and g(3) below:</u>
- g(0) = -2*0² + 3*0 - 5
-
g(0) = -5
------------------
- g(3)= -2*3² + 3*3 - 5
- g(3) = -18 + 9 - 5
- g(3) = -14
