Charles predicts he will get 97 points on the test at the end of the week. if charles gets 87 points on the test, what is charles' percent error? round your answer to the nearest tenth of a percent

Percent error = 10.3%

Step-by-step explanation:

Given that:

Predicted points = 97

Obtained points = 87

Error = 87 - 97= 10

We know that:

Percent error = [error / predicted (actual) value] * 100

Percent error = 10/97 * 100%

Percent error = 10.309%

Rounding off to nearest tenth:

Percent error = 10.3%

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
