The answer is that the assumed margin of error is 5%.
Here is how we calculate this;
<span>presidential approval rating is between 47% and 57%
</span>(57% - 47% ) / 2 = 10/2 = 5%
Answer:
Sec (x) - 2 tan (x)
Step-by-step explanation:
Answer:
240
Step-by-step explanation:
So here’s the step by step (for the show your work thingy)
so we can write an equation
0.05x=12
We use 0.05 becuase 5 percent is basically 5/100 and the x is used becuase we don’t know what the number is and the =12 is for the number that came out as a final result
ow we can solve the equation
x=12/0/05
x=240
Final answer is 240
Take the logarithm of both sides. The base of the logarithm doesn't matter.
Drop the exponents:
Expand the right side:
Move the terms containing <em>x</em> to the left side and factor out <em>x</em> :
Solve for <em>x</em> by dividing boths ides by 5 log(4) - log(3) :
You can stop there, or continue simplifying the solution by using properties of logarithms:
You can condense the solution further using the change-of-base identity,
