So what will it be a percentage of? it will be the percentage of the original recruits, of the original 150.

for this, we need to divide the number of recruits that left over all recruits, and multiply by 100%: $\frac{30}{150} *100%= \frac{1}{5} *100%=20%$

so the number of trainees decreased by 20 %

What is the slope of the line with the equation y-3=-1/2(x-2)?

torisob [31]

Answer: $-\frac{1}{2}$

Step-by-step explanation:

$y -3 = -\frac{1}{2}(x-2)$

Write as slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.

$y-3=-\frac{1}{2}x + 1$

$y = -\frac{1}{2}x+4$

Therefore, the slope is $-\frac{1}{2}$ .

Which of the following is not one the three categories of Euclid’s geometric principles?

Nikolay [14]

"Conjeture" is not one of the three categories of Euclid's geometric principles.

Euclidean geometry begins with Euclid's Elements, which is both a sum of the geometric knowledge of the time and an attempt to formalize this knowledge mathematically.

The notions of straight line, plane, length, area are exposed there and form the support of elementary geometry lessons. The conception of geometry is intimately linked to the vision of the ambient physical space in the classical sense of the term.
