Answer: 80
Step-by-step explanation:
We can use the formula , where are the lengths of the diagonals.
By the distance formula,
So, the area is
If two angles are supplementary, their sum equals 180 degrees
<u>Answer:</u>
The probability of getting two good coils when two coils are randomly selected if the first selection is replaced before the second is made is 0.7744
<u>Solution:</u>
Total number of coils = number of good coils + defective coils = 88 + 12 = 100
p(getting two good coils for two selection) = p( getting 2 good coils for first selection ) p(getting 2 good coils for second selection)
p(first selection) = p(second selection) =
Hence, p(getting 2 good coil for two selection) =
3.4x3=10.2...
