Step-by-step explanation:
<u>Step 1: Define Inequality</u>
15 < -5x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Divide -5 on both sides: -3 > x
- Rewrite: x < -3
Here we see that any number <em>x</em> that is smaller than -3 would work as a solution to the inequality.
True because 6 multiplied by 3 is 18. Therefore, when you divide 18 by 6 the anwser will be 3.
The younger brother will be 48 when Adam is 50
The <em>correct answer</em> is:
B) precise
Explanation:
Precision can be broken down into two pieces:
<em>Repeatability </em>- The variation observed when the same person measures the same thing repeatedly with the same device.
<em>Reproducibility</em>: The variation observed when different people measure the same thing using the same device.
If two measurements are very close to each other, this gives repeatability. If the measurements were made by different people, this gives reproducibility.
<em>Accuracy</em>, however, describes the difference between the measurement and the thing's actual value. This would not involve getting the same result repeatedly; it would be getting the <em>correct</em> value.
