Simply get the value of the angle and distribute away.
Answer:x= 25
Step-by-step explanation:
504.2x + 29,165.8 is the number to divided by x.
<u>Given:</u>
The given function is 
We need to determine the reflection of f(x) over the x - axis
<u>Reflection over x - axis:</u>
The translation rule to reflect over the x - axis is given by

Reflecting the function over the x - axis, we get;

Multiplying -1 to both sides of the equation, we have;

This can be written as

Hence, the reflection of the function over the x - axis is 
Thus, Option A is the correct answer.
Answer:
The standard error increases and the width of the interval increases
Step-by-step explanation:
The variance is equal to the square of the standard deviation. An increase in variance will increase the standard deviation.
The width of the confidence interval can be defined as:

The width is proportional to the standard deviation, so when the variance increases, the standard deviation and also the width of the interval increases.
