A digital scale reports a 10 kg weight as weighing 8.975 kg
sergiy2304 [10]

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</span>

Which inequality is represented by this graph? 0 - 345&gt; x O 0 -34.5 0 -355 cx​
julia-pushkina [17]

Answer:

Step-by-step explanation:

If x is the white dot on the graph:

From what it looks like, x is right between -35 and -34 x (which is -35.5).

If that is the case then none of the answers are correct since -35.5 is <u>equal or less</u> than x. (the sign looks like this:  "\leq" )

But if you have to choose one of the answers then number 4 (-35.5 < x) would be closest.

7x/5+5/2=x/10+1/5<br> SHOW WORK!!! <br> PLEASE HELP!!!!<br> WILL MARK BRAINLIEST
Anettt [7]

Answer:

- 23/13

Step-by-step explanation:

1. Subtract 5/2 from both sides of the equation.

2. Simplify

7/5 = /10 − 23/10

3. Multiply all terms by the same value to eliminate fraction denominators.

7/5 = /10 − 23/10          2 ⋅ 5 ⋅ 7/5 = 2 ⋅ 5( /10 − 23/10)

4. Simplify

14 = − 23

5. Subtract from both sides of the equation.

14 = − 23                              14 − = − 23 −

6. Simplify

13 = − 23

7. Divide both sides of the equation by the same term.

13<em>x </em>= −23                          13x/13 = -23/13

8. Simplify

= −23/13

Problem<br> What is the slope of the line that contains these points?<br> ***********<br> slope:
Leokris [45]
Answer: -8

Explanation: the formula to find slope is

y1 - y2/x1 - x2

When you substitute the values in this formula, you get

= 36 - 12/8 - 11
= 24/-3
= -8

Therefore, the slope is -8
