Accuracy refers to how close a measurement is to the true value of what is being measured. Accuracy refers to the closeness of measurements of the same quantity, even if they are not close to the true value. so the answer is correct hope this helps
just say C Explanation: I understand
answer 6
The second alloy weighs 35-2x pounds and contains 15% silver, so the weight of silver in this alloy is (35-2x)*0.15 pounds. 35 pounds of mixed alloy contains 38% silver, or 35 *0.38=13.3 pounds. If you add the silver weights of two alloys, you get the weight of 13.3 pounds (the weight of the mixed silver alloy). x+(35-2x)*0.15=13.3x+5 ,25-0, 3x=13.30,7x=13.3- 5.25 = 8.05 x = 8.05 ÷ 0.7 = 11.5 pounds (silver content of the first alloy) and 2x = 23 pounds is the premier league weight. 35-23 = 12 pounds is the weight of the second alloy and 12*0.15 = 1.8 pounds (silver content of the second alloy).
Measurements close to the correct value are accurate. The correct option out of all the options given in the question is the third option or the penultimate option. Other options that are given can be overridden. I hope this is the answer that really helped you.
Measurements close to the correct value are accurate.
Measurements are values obtained by determining the quantity, size or level of something. Measurements are usually expressed in numbers. Measured values close to the correct or standard value are accurate. For example, if the actual weight (measurement) of a cup is 10 kg and an individual weighs the same cup and gets a weight measurement of 4 kg, the measurement is not accurate. Measurements close (such as 9.5 kg or 9.8 kg) to the actual value (10 kg) are accurate.
Answer 7
Measurements close to the correct value are accurate.
To accommodate different and unique sizes of people, patterns have been created. The specific measurement against which other measurements are compared to check for uniformity is called the measurement standard. Measurements are generally considered accurate when they are widely accepted. There are different measurement systems that were created to ensure size uniformity, such as the metric system and the FPS system for the United States. The metric system includes measurement standards such as grams, seconds, and degrees Celsius.
