Answer:

1.4%

Step-by-step explanation:

Actual Length = 14.7 inches

Wrong Measurement = 14,5 inches

Error in Measurement = 14.7 -14.5 =0.2 inches

Percentage Error = (Error in Measurement/Actual Value) X 100

=(0.2/14.7) X 100

=0.0136 X 100

=1.36%

Percentage Error=1.4% (to the nearest tenth)

Answer:

%Error = |14.5 - 14.7|/14.7 × 100% = 0.2/14.7 × 100%

%Error = 1.36 %

To the nearest tenth of the percent

%Error = 0%

Step-by-step explanation:

Percentage error is used to determine how accurate a measurement is, it can be written mathematically as;

%Error = |measured - actual value|/actual value × 100%

Given;

Measured value = 14.5 inch

Actual value = 14.7 Inch

%Error = |14.5 - 14.7|/14.7 × 100% = 0.2/14.7 × 100%

%Error = 1.36 %

To the nearest tenth of the percent

%Error = 0%

Jordan flipped a coin 492 times. Which of the following would be a good estimate of the number of times the coin landed on heads
Irina-Kira [14]
I'd say B. but that's only because I divided the number of times he flipped the coin by the number of sides it has, 2, and came up with 246. The closest number on here to that is 231 or B. I hope I helped.
