Answer:

The percent error based on the average measurements is 0.8%.

Step-by-step explanation:

The standard equation for percent error is [(original - actual)/original} x 100. The original amount is 100 degrees celcius. Your average measurement can be found by adding the three temperatures together and dividing by the number of temperatures collected: 98.5 + 99.3 + 99.8 = 297.63/3 = 99.2. When we place our numbers into the equation and solve, we get: (100 - 99.2)/100 = 0.008 x 100 (to get our percentage) = 0.8%.

$\text{State Income Tax Rate: }6.65\%, \\\text{Deduction: }\$7,702.03$

Answer:

State income tax: $6.65\%$

Step-by-step explanation:

Based on the interface, it seems like you have chosen lawyer as a career with the given salary of $115,820.

The chart given for state income tax is broken into two categories:

$21,400-$80,650 => 6.45%

$80,651-$215,400 => 6.65%

Since the chosen career's salary is $115,820, the career falls into the second range of 6.65% state income tax.

The deduction is simply the amount of money taxed. For a 6.65% state income tax, the deduction can be found from:

$115,820\cdot 0.0665=\boxed{\$7,702.03}$
