I think B should be the top one
In order to prove Rathan wrong, we only need one counterexample. Take the number 6. 6 is even, but it has the odd number 3 as a factor, so clearly, not all factors of even numbers are even.
Step-by-step explanation:
W=-6, x=1.2, and z=-6/7
(W²x-3)÷10-z
we substitute
((-6²)(1.2)-3)÷10-(-6/7)
((-36)(1.2)-3) ÷10-(-6/7)
(-43.2-3) ÷10(6/7)
(-46.2)÷60/7
-46.2÷60/7
-46.2*7/60
-46.2/1*7/60
-323.4/60
-5.39
The percent error is 4.167 %
<em><u>Solution:</u></em>
Given that, Mrs Franklin's speedometer said she was driving at a rate of 48 miles per hour
When checking the accuracy of her speedometer, an Automotive Specialist recorded her speed at 50 miles per hour
<em><u>The percent error is given by formula:</u></em>
Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%

From given,
Experimental value = 50
Theoretical value = 48
<em><u>Substituting the values in formula, we get,</u></em>

Thus the percent error is 4.167 %
