The probability of drawing a quarter is D, 40%
If we set the problem up in a fraction, 16 of the total 40 coins are quarters.
16/40= .4 or 40%
Hope this helped! :D
Answer:
Answer is D.
Step-by-step explanation:
Which is not true?
So, lets assess the answers given to the question.
A. It is the equation of a horizontal line.
Yes, it is. Since there is only one y - value which is y = -4, we can confirm this is the y intercept, so therefore the x value is zero. But it's not the answer we're looking for.
B. It's slope is zero, yes the slope is zero. It only lists the y-intercept which confirms that the slope is 0.
C. Yes, I mean i can't really explain how. Just use desmos calculator, the graph is exactly perpendicular.
D. The line actually does cross the x-axis, -4 is the y intercept and the x value is 0, and zero is still a point. So D is the one which isn't correct making it the correct answer.
The answer is 41 have a good day
<em>These triangles are congruent, it means all sides are equal.</em>
<em>We equate the sides that are equal and we get this two equations:</em>
x = y + 1 -------------- (1)
x + 3 = 3y -------------(2)
Sub (1) into (2)
(y + 1) + 3 = 3y
y + 1 + 3 = 3y
3y - y = 3 + 1
2y = 4
y = 2 -------------- sub back into (1)
x = y + 1
x = 2 + 1
x = 3
Ans: x = 3, y = 2
