The error that occurred is a systematic error.
<h3>
What is random error?</h3>
Random error is a type of error that causes one measurement to differ slightly from the next.
<h3>
What is systematic error?</h3>
Systematic error is a type of error that affects measurements in the same amount or by the same proportion, provided that readings are taken in the same way.
The three measurements 548.5 g, 548.9 g, and 548.7 g differ slightly but in the same amount and proportion.
Therefore, a systematic error occurred during the determination of the mass of the substance because the readings were taken in the same way and the measurement differ in the same amount.

Answer:
radius is 8 ft
Step-by-step explanation:
circumference formula is 2pi r
so if the circumference is 16 pi, we divide it by 2 to get 8 pi and divide it by pi to get 8.
1 is close to 1
3/4 is close to 1

Answer:</h2><h2>
The city population last year = 2233 approximately</h2>
Step-by-step explanation:
The current population of the city = 245,600
Rate of increase = 110 %
The population in previous year = ?
Let x be the population of previous year
x(110%) = 245600
x = 
= 2232.7
The city population last year = 2233 approximately
So for the first one, you would have to multiply 2 six times. and then 2 with a -4 exponent is a little challenging. Okay, you would have to make it a fraction. so it would be 1/16. then you would just multiply 2 seven times.
