Using it's formula, considering the results, it is found that the accuracy of the test is of 0.95 = 95%.
<h3>What is the accuracy of a test?</h3>
It is given by the <u>number of correct results divided by the number of tests</u>.
In this problem, there were 80 tests, of which 80 - 2 - 2 = 76 had correct results, hence the accuracy is given by:
A = 76/80 = 0.95 = 95%.

Area = length x width.
Area = 10 1/4 x 10 1/4 = 105 1/16
Answer:
D. 161°
Step-by-step explanation:
m<2 is congruent to m<4, m<1 is congruent to m<3 by properties of a parallelogram
to find x:
4x-17=3x-8
x-17=-8
x=9
m<4=3(9)-8=19
so, m<4=19°
m<2 =19°
to find m<1:
the interior angles of a parallelogram add up to 360°
360-2(19)=2x
2x=360-38
2x=322
x=161°
m<1=161°
