The probability of choosing a purple marble from the given parameters is given as; 29%
<h3>How to find the Probability?</h3>
We are given;
Probability of drawing an orange marble = 23% = 0.23
Probability of of drawing a white marble = 48% = 0.48
Thus, probability of drawing a purple marble is;
P(purple marble) = 100% - (23% + 48%)
P(purple marble) = 29%

-3x+7y=5 (x2) -> -6x+14y=10
-6x+14y=10
-8x+14y=-10
——————— -
2x=20
x=20/20
x=1
Susbstitute x=1,
-8x+14y=-10
-8(1)+14y=-10
-8+14y=-10
14y=-10+8
14y=-2
y=-2/14
y=-1/7
I hope it helps
It would be a 1/5 chance so maybe 10
Answer:
16. B
17. B
Step-by-step explanation:
16. The intercept form of the parabola is
where 
are two x-intercepts.
In your case,
so
To find <em>a</em>, substitute coordinates of the point (-6,-4) parabola is passing through
and
17. The vertex form of the parabola equation is
where <em>(h,k)</em> are the coordinates of the vertex and sign "-" because parabola goes down.
In your case, vertex is (2,3), so
The vertex is 3 units from the focus, then
The equation of the parabola is
Answer:
the answer is c
Step-by-step explanation:
because it scales up and moves to the right
