Langston estimated the temperature to be 45°F . The thermometer showed the actual temperature to be 50°F. Complete the steps bel
1 answer:
The percentage error is 11.1%
<h3>What is percentage error?</h3>Percentage error is simply the difference between the exact and the estimated values as a percentage
The given parameters are:
- Estimate = 45
- Actual = 50
The percentage error is then calculated as:
Evaluate the difference
So, we have:
Hence, the percentage error is 11.1%

The path is in the shape of a parabola, the horizontal length is 24, so the middle point is at x=12, the symmetry line is x=12, the highest point (the vertex) is at (12,6)
the equation in vertex form is y=a(x-12)²+6
next, find a by using either one of the two points, the starting point (0,0) or the end point (0,24). obviously (0,0) is easier to calculate:
0=a(0-12)² +6
a=-1/24
so the quadratic equation is y=-
