Answer:

Niether of them are correct

Step-by-step explanation:

If you actually put into your calculator 2^28, it equals 268,435,456. This is because you're not just squaring 28, you are multiplying 2 by 2-- 38 times. This will quickly add up, even if you start out with 2 it will create a very large number.

A student estimated a mass of 250grams, according to the scale the mass is actually 240grams. What is the percent error? (round
NeX [460]

Answer:

4.2%

Step-by-step explanation:

percent error = (estimated value - actual value)/(actual value) × 100%

Here, the estimated value is 250 g, and the actual value is 250 g.

percent error = (estimated value - actual value)/(actual value) × 100%

percent error = (250 g - 240 g)/(240 g) × 100%

percent error = 10/240 × 100%

percent error = 0.041666... × 100%

percent error = 4.2%
