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%.

V≈167.55
Answer:
a = 1 1/15
Step-by-step explanation:
1/4 a = 4/15
Multiply each side by 4 to isolate a
4 * 1/4a = 4 * 4/15
a = 16/15
a = 1 1/15
Answer:
Area of circle= 81π
Area of triangle= 371.8 yards
Step-by-step explanation:
<em>2) Area of circle = πr²</em>
<em>Area of circle = π*(18/2)²</em>
Area of circle = 81π
Therefore, the area of circle is 81π.
<em>4) Area of triangle = 1/2*base*height</em>
<em>Area of triangle = 1/2*22*33.8</em>
Area of triangle = 371.8 yards
Therefore, the area of the triangle is 371.8 yards.
