The answer is y = 15. Is this a trick question?
Divide the number of possible outcomes by the number of total outcomes.
Green: ≈ 0.55
Red: = 0.45
Since only red counters were added, this changes the probability of the counter being red to 0.6 or 60% and the probability of it being green to 0.4 or 40%. This means that the change in probability for the red counters was 15% or 0.15.
Set up a proportion:
, so x = 1.65, which rounds to 2 red counters.
We can prove this by adding 5 + 2 red counters. 7/11 = 0.6 or 60% chance.
Your final answer is 2 red counters were added.
Hope this helped. Get well soon.
Answer:
Please check the graph diagram attached.
From the diagram,
- The red line represents the parent function f(x) = x + 8
- The blue line represents the translated function f(x) = x + 3
It is clear the parent function f(x) = x+8 has been translated down 5 units.
Step-by-step explanation:
The rule to determine the translating down 'b' units:
f(x) – b
It means if we have to translate a function f(x) 'b' units down, all we need is to subtract the 'b' units from the function output.
Given the function
f(x) = x + 8
In order to translate 5 units down, all we need is to subtract 5 units from the function.
i.e.
f(x) = x + 8 - 5
f(x) = x+3
Thus, we conclude that f(x) = x+3 is the translated function.
