A digital scale reports a 10kg weight as weighing 8.975kg. which of the following is true?

1 answer:

6 0

That question is accompanied by these answer choices:

<span>A. The scale is accurate but not precise.
B. The scale is precise but not accurate.
C. The scale is neither precise nor accurate.
D. The scale is both accurate and precise.

Then you need to distinguish between accuracy and precision.

Accuracy refers to the closeness of the measure to the real value, while precision, in this case, refers to the level of significant figures that the sacle report.

The fact that the scale reports the number with 4 significant figures means that it is very precise, but the fact that the result is not so close to the real value as the number of significan figures pretend to be, means that the scale is not accurate.

So, the answer is that the scale is precise but not accurate (the option B).

The figure below shows a shaded region and a nonshaded region. Angles in the figure that appear to be right angles are right ang

serious [3.7K]

16 x 8 = 128 square feet (area of rectangle)

shaded:
8 x 2 = 16
10 x 1 = 10
1/2 (3)(10) = 15

total shaded area: 16+10+15 = 41 square feet
total non-shaded area = 128 - 41 = 87 square feet

answer

area of the shaded region = 41 square feet
area of the non - shaded region = 87 square feet

What is the measure of the smallest interior angle of the hexagon shown?

yan [13]

<h3>Answer: C) 70 degrees</h3>

=========================================================

Explanation:

We have n = 6 sides, so the interior angles must add to 180(n-2) = 180(6-2) = 720 degrees

Lets add up the angles, set the sum equal to 720 and solve for x

x+2x+115+2x+115+2x = 720

7x+230 = 720

7x = 720-230
