Using the Empirical Rule, it is found that 49.85% of buyers paid between $150,000 and $154,800.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
Considering the given mean and standard deviation, the interval between $150,000 and $154,800 corresponds to the interval between the mean and 3 standard deviations above the mean.
The normal distribution is symmetric(50% above the mean, 50% below), hence the percentage corresponding to this interval is:
P = 0.5 x 99.7% = 49.85%.

Step-by-step explanation:
the estimated increase in height of baby each year would be 3 inches.
I believe the answer is 3. Order of Operations is Parenthesis Exponents Multiplication and Division solve left to right and Addition and Subtraction solve left to right
The shape in the middle is a quadrilateral, so the bottom right hand corner should add up to the rest of the angles to give 360 degrees.
40 + 80 + 110 = 230°
360 - 230 = 130°
The line on which x is on is a straight line, and a straight line is 180 degrees.
Therefore x has to be 180 - 130 to make sure it adds up to give 180 degrees.
180 - 130 = 50
∴ x = 50°
