The value of x is 30; hence 4x is equal to 120. That is because the sum of the angles of a triangle is 180. So, add x, x and 4x together, you get 6x. Divide 180 by 6, you get 30. Hope this helped!
0.25 is the probability that you would select a score between 300 and 700. I used the empirical rule when i solved this.
Answer:
Coordinate D. Because D lies on the 2nd quadrant, meaning that x has a negative value whereas y is positive.
The answer is:put the equation xa+yb=1 to the slope intercept form and find its slope and y-intercept.
Ex: l -3 l = 3.
the two vertical lines on either side stand for absolute value, or the distance to 0 from the given number.
THE ANSWER WILL ALWAYS BE POSITIVE (except...)
however, if there is a negative sign on the OUTSIDE of the bars, the answer will be NEGATIVE.
ex: - l -4 l = -4
ex: l -4 l = 4
