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%.

Answer: m less-than-or-equal-to 17
Step-by-step explanation: First lets write an equation to solve for m, the amount of miles Henry can afford in the taxi.
The inequality 0.75m - 1.25 less than or equal to 14 represents this.
Solve for m.
0.75m - 1.25 + 1.25 = 14 - 1.25
0.75m = 12.75
We need to make m be equal to one mile not 0.75, so divide both sides by 0.75.
0.75m/0.75 = 12.75/0.75
m = 17
So m is less than or equal to 17
Answer:
a = 3
Step-by-step explanation:
Factorize (x+5)(x-4)(x+2)
(x+5)(x-4)(x+2)
= (x²-4x+5x-20)(x+2)
= (x²+x-20)(x+2)
= (x³+2x²+x²+2x-20x-40)
= x³+3x²-18x -40
Compare with x^3+ax^2
3x² = ax²
3 = a
Rearrange
a = 3
Hence the value of a that makes the expressions identical is 3
