Answer:
x = 3.5
Step-by-step explanation:
(10x + 15) = 30
10x + 15 = 30 * 
10x + 15 = 10 * 5
10x + 15 = 50 {Subtract 15 form both sides}
10x = 50 -15
10x = 35 {Divide both sides bt 10}
10x/10 = 35/10
x = 3.5
Answer: D) how close a measured value is to the actual value.
Step-by-step explanation: Accuracy is simply a measurement metric which is used to establish how a measured or predicted value conforms to the actual measurement usually in terms of closeness. Accuracy is different from precision which measures closeness in values obtained from repeated measurement of the same sample. For instance;
If the actual vale of a measurement is : 11.34
Prediction 1 : 11.30
Prediction 2 : 11.32 ;
Prediction 2 will be said to be more accurate than prediction 1 becuase it is closer to the actual value than prediction 1.
