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%.

In order to find the other end point we must know where the End point is.
·(5,-3)
In order to find out the new point we must know how long the line segment is.
·8 units.
Knowing this we would use the equation ΔY/ΔX to find the new point
·ΔY= Y²-Y
·ΔX=X²-X
Knowing this we just plug our points in, and we use process of elimination to get our answer.
First we will try choice A.
· (5,-3)
·(-3,-3)
To get from Y²⇒Y= 8 Units, and to get from X²⇒X=0 Units.
·8+0=8
-In conclusion your answer is A, i hope this is the answer you are looking for, feel free to post your questions here on brainly in the future.
If $3 was 25% of the original price then 3*4 = $12
<span>Given:
AB = x + 16
BC = 4x + 11
AC= 77
We can safely assume that,
AB + BC = AC
x + 16 + 4x + 11 = 77
5x + 27 = 77
5x = 77 - 27
5x = 50
x = </span>
x = 10
Hence,
AB = x + 16 = 10 + 16 = 26
Hence, proved.
1a) no it would be 54
1b) yes
1c) yes
1d) no it would be 40
1e) yes
hope this helped
