Reason:
There are 4 outcomes we don't want (rolling 1,2,3 or 4) and 2 outcomes we do want (rolling 5 or 6)
This gives the odds against ratio of 4:2 or 2:1
This can be written out as "2 to 1" or "two to one".
Having 2 to 1 odds means that we're twice as likely to get something we don't want vs something we do want.
Side note: the odds in favor will have us flip the ratio.
A group of 5 friends each have x action figures in their collections. Each friend buys 6 more action figures. Now the 5 friends have a total of 150 action figures. How many action figures did each friend start with?
Answer:
29
Step-by-step explanation:
The problem is 5x + 6 = 150
I subtract 6 from each sides except the one with the variable.
6 - 6 = 0 and 150 - 6 = 144.
Then I bring 5x down.
Then I divided 5x with 5 and 144 with 5.
I got 28.8 for x, which means the friends had 28.8 action figures each.
And I don't think it would be possible for them to have 28.8 action figures, so you round to a whole number which would give you the answer 29.
I think I that makes sense.

Step-by-step explanation:
Leslie set up a fruit stand to sell some of her crop of oranges. The first person who came by bought 1/3 of her oranges. The second person bought 4 oranges. The thrid person bought 1/4 of the REMAINING oranges. Leslie took the last 15 oranges home to make orange juice. How many oranges did Leslie have at the beginning?
Answer:
36
Step-by-step explanation:
Let's say Leslie starts with x oranges.
The first person buys 1/3 of the oranges, leaving behind 2/3 x.
The second person buys 4 oranges, leaving behind 2/3 x − 4.
The third person buys 1/4 of the remaining oranges, leaving behind:
3/4 (2/3 x − 4)
This amount equals 15. Solving for x:
15 = 3/4 (2/3 x − 4)
20 = 2/3 x − 4
24 = 2/3 x
36 = x

In a study of patients arriving at a hospital emergency room, the gender of the patients is considered, together with whether the patients are younger or older than 30 years of age, and whether or not the patients are admitted to the hospital. It is found that 45% of the patients are male, 30% of the patients are younger than 30 years of age, 15% of the patients are females older than 30 years of age who are admitted to the hospital, and 21% of the patients are females younger than 30 years of age. What proportion of the patients are females older than 30 years of age who are not admitted to the hospital?
The probability of patients are females older than 30 years of age who are not admitted to the hospital is 0.19
How to calculate the probability?The probability of patients who are females and are admitted will be 0.15. The probability of those younger than 30 years will be 0.21.
The proportion of the patients are females older than 30 years of age who are not admitted to the hospital will be:
= [(1 - 0.45) - 0.21] - 0.15
= 0.19

2x-3y=7
-3x +7y = - 8
4x-3y = 9
2x + 3y = 9
SOLVE BOTH EQUATIONS??
Answer:
(5, 1 ) and (3, 1 )
Step-by-step explanation:
2x - 3y = 7 → (1)
- 3x + 7y = - 8 → (2)
multiplying (1) by 3 and (2) by 2 and adding will eliminate x
6x - 9y = 21 → (3)
- 6x + 14y = - 16 → (4)
add (3) and (4) term by term to eliminate x
0 + 5y = 5
5y = 5 ( divide both sides by 5 )
y = 1
substitute y = 1 into either of the 2 equations and solve for x
substituting into (1)
2x - 3(1) = 7
2x - 3 = 7 ( add 3 to both sides )
2x = 10 ( divide both sides by 2 )
x = 5
solution is (5, 1 )
------------------------------------------------------------
4x - 3y = 9 → (1)
2x + 3y = 9 → (2)
adding the 2 equations term by term will eliminate y
6x + 0 = 18
6x = 18 ( divide both sides by 6 )
x = 3
substitute x = 3 into either of the 2 equations and solve for y
substituting into (2)
2(3) + 3y = 9
6 + 3y = 9 ( subtract 6 from both sides )
3y = 3 ( divide both sides by 3 )
y = 1
solution is (3, 1 )

15 (y - 4 ) - 2 ( 9y - 11 ) = 4 (8z - 13)
Answer to the given equation is 32z + 3y = 14.
Step 1: Given data: The given equation is 15 (y - 4) - 2 (9y - 11 ) = 4 (8z - 13)Step 2: Solving the above equation,15y - 60 - 18y + 22 = 32z - 52
- 3y - 38 = 32z - 52
- 3y + 52 - 38 = 32z
- 3y + 14 = 32z
32z + 3y = 14

Step-by-step explanation:
We are asked to solve the system of equations simultaneously.
We need to equate the equations.
=============================================================
Solving :
⇒ -4 + 2x = 4x + 2
⇒ 4x - 2x = -4 - 2
⇒ 2x = -6
⇒ x = -3
============================================================
Finding y :
⇒ y = 4(-3) + 2
⇒ y = -12 + 2
⇒ y = -10
============================================================
Hence, the solution :
(-3, -10)
We have to solve them graphically as per question
