How many significant figures does the number 520 have? What is the difference between a systematic error and a random error?

1 answer:

6 0

I'd say there are two significant figures in the number 520, and those are 5 and 2, because trailing zero in a number without decimals is rarely considered to be significant.
Now, the difference between a systematic error and a random error is that a systematic error occurs over and over again, whereas a random error is random and may never be repeated.

If QT is 9 and TP is 8 Find the length of the following:<br><br>RP<br>RT<br>RS

anyanavicka [17]

Answer:

i. RP = 17

ii. RT = 15

iii. RS = 30

Step-by-step explanation:

Given that; QT = 9 and TP = 8.

From the diagram, join R to P. Thus RP = QP (radius of the circle)

RP = QT + TP

= 9 + 8

RP = 17

Applying Pythagoras theorem to triangle TRP;

RT = $\sqrt{(RP)^{2} - (TP)^{2} }$

= $\sqrt{17^{2} - 8^{2} }$

= $\sqrt{225}$

= 15

∴ RT = 15

But, RT = TS = 15.

So that;

RS = 15 + 15

= 30

RS = 30

Therefore; RP = 17, RT = 15 and RS = 30.
