Answer:
0.0449
The required percentage = 4.49%
Step-by-step explanation:
38% experienced filesharers decreased spending
3% of music fans have broadband access
25% of other fans have reduced spending
A = event that fan is a file sharer and has broadband access
B = event that fan has decreased spending on music
P(B|A) = 0.38
P(A) = 0.03
P(B|A') = 0.25
To answer this question I used bayes theorem.
[P(B|A).P(A)] / [P(B|A).P(A) + P(B|A').P(A')]
= 0.38x0.03/(0.38x0.03) + 0.25(1-0.03)
= 0.0114/0.114+0.2425
= 0.0114/0.2539
= 0.0449
Therefore the required percentage is 4.49% or 4.5%
Let the answer be x percent:
So we say: the tax is x% of the price,
this means: $3.56 is x% of $89
"something %" means 1/100 times something,
thus, we write and solve the following equation:
Answer: the tax is 4%
The options 2 and 4 would have the same graphical representation.
Step-by-step explanation:
Step 1:
To determine which functions are equal to the question, we must assign values to x and see which values equal the function f(x) = .
Any random value can be assigned to x but the same value of x must be assigned to all the equations.
Step 2:
If we substitute x = 5, we get
Question; f(x) =
Option 1; f(x)
Option 2; f(x) =
Option 3; f(x) =
Option 4; f(x)
So options 2 and 4 would have the same graphical representation.
Ah, great question. Let me help you on this one.
We need to balance both equations for this to work out. This is needed because question asks us for an x variable that will make both equations equal to each other.
Let's write it out so it's easier for us to understand.
Let's not forget to multiply both sides by 100.
Let's start by subtracting 45 from both sides.
Let's simplify it.
Now, we need to subtract 375 from both sides.
Simplify it once again.
Divide both sides by -125
