Answer:
the answer is D and A hope this helps
Since the precision of the voltmeter is <span>±0.005 V, the effective value range for the first measurement is 9.000 V to 9.010 V, for the second it is 9.001 V to 9.010 V, the third 9.013 V to 9.023 V and the fourth 9.021 V to 9.030 V. From all of these measurements the only one which the accepted value falls within the range is measurement 3.</span>
Answer:
see explanation
Step-by-step explanation:
Since the triangles are similar then the ratio of corresponding sides are equal
(a)
= 
, substitute values
= 
( cross- multiply )
13.23AB = 111.132 ( divide both sides by 13.23 )
AB = 8.4
(b)
= 
, substitute values
= 
( cross- multiply )
6.3DF = 54.243 ( divide both sides by 6.3 )
DF = 8.61
Answer: first option 0 to 30 minutes.
Jusitification:
Interpolation is the prediction of an intermediate value using a linear model.
In this case, she has the data for 0, 5, 10, 15, and 30 minutes.
So, she can interpolate between any pair of consecutive data to find an intermediate value.
For example: i) if she wants the value for 20 minutes, she can interpolate between 15 and 30 minutes, ii) if she wants the value for 7 minutes, she can interpolate between 5 and 10 minutes, iii) if she wants the value for 12 mintues, she will interpolate between 10 and 15 minutes.
