Answer:
6 and - 18
Step-by-step explanation:
let the 2 integers be a and b , then
a + b = - 12 → (1)
[tex]\frac{a}{b}[/tex] = - 3 → (2)
multiply both sides by b ( b ≠ 0 )
a = - 3b
substitute a = - 3b into (1)
- 3b + b = - 12
- 2b = - 12 ( divide both sides by - 2 )
b = 6
substitute b = 6 into (1) and solve for a
a + 6 = - 12 ( subtract 6 from both sides )
a = - 18
the two integers are - 18 and 6

A bag contains 3 gold marbles, 5 silver marbles, and 26 black marbles. Someone offers to play this game: You randomly select one marble from the bag. If it is gold, you win $3. If it is silver, you win $2. If it is black, you lose $1. What is your expected value if you play this game?
The expected value if you play this game will be -$0.205.
Let the number of gold, silver, and black marbles be P1, P2, and P3, respectively.
Given, The bag contains,
Number of gold marbles (P1) = 3
Number of silver marbles (P2) = 5
Number of black marbles (P3) = 26
Also given,
The winning value if a gold marble is selected = $3
The winning value if a silver marble is selected = $2
The losing value if a black marble is selected = $1
Probability = Expected value/ Sum of the total number of events
Probability of picking a gold marble,
P1 = 3/ (3+ 5+ 26)
= 3/34.
Probability of picking a silver marble,
P2 = 5/ (3+ 5+ 26)
= 5/34.
Probability of picking a black marble,
P3 = 26/ (3+ 5+ 26)
= 26/34.
The expected value if you play the game will be,
Value = ($3) P1 + ($2) P2 + (-$1) P3
= ($9/34) + ($10/34) - ($26/34)
= - ($7/34)

The odds in favor of an event occurring are given. Compute the probability of the event occurring. (Enter the probability as a fraction.) 8 to 9
The probability expression when converted from odd's expression is 8/17
How to determine the probability?From the question, we have the following odd parameters
Odd = 8 to 9
To start with, we need to express the odd as ratio
So, we have the following representation
Odds ratio = 8 : 9
Solving further, we need to express the ratio as fraction
So, we have the following representation
Odds fraction = 8/9
To convert the above odd's expression to probability expression, we make use of the following equation
This is represented as
P = Odds/(Odds + 1)
Substitute the known values in the above equation
So, we have the following equation
P = (8/9)/(8/9 + 1)
Evaluate the sum
This gives
P = (8/9)/(17/9)
Express the quotient as product
P = (8/9) * (9/17)

Given: ∠2≅∠3 Prove: ∠1 and ∠3 are supplementary
The proof to the above diagram is ∠1 + ∠3 = 180
What are Supplementary angles?Supplementary angles are angles whose sum equals 180°
If angle A + angle B = 180°, then both angles are said to be supplementary, meaning angle A is the supplement of Angle B.
∠2 ≅ ∠3. This means ∠2 is approximately equal to ∠3
Also ∠1 + ∠2 = 180°( sum of angles on a straight line)
making ∠2 the subject of the equation
∠2 = 180 - ∠1
But ∠2 ≅ ∠3, which we can say that ∠2 = ∠3
substituting ∠2 for ∠3 in the equation, we have
∠3 = 180 - ∠1
which is further simplified as,
∠1 + ∠3 = 180°
Which means both angles are also supplementary.
In conclusion, both angles are supplementary as ∠1 + ∠3 = 180
