Answer:
Probability of picking Red ball is 27.5%
Step-by-step explanation:
Given:
Total Number of balls = 200
Number of White balls = 100
Number of Red balls = 55
Number of Black balls = 45
We need to find the probability of the ball picked to be red.
Solution:
Now we know that;
Probability is equal to number of Possible Outcomes divide by total number of Outcomes multiplied by 100.
framing in equation form we get;
Hence Probability of picking Red ball is 27.5%.
Answer:
Step-by-step explanation:
Let A = R−{0}, the set of all nonzero real numbers, and consider the following relations on A × A.
Given that (a,b) R (c,d) if
Or (a,b) R (c,d) if determinant
a) Reflexive:
We have (a,b) R (a,b) because ab-ab =0 Hence reflexive
b) Symmetric
(a,b) R (c,d) gives ad-bc =0
Or da-cb =0 or cb-da =0 Hence (c,d) R(a,b). Hence symmetric
The y-coordinate is 16
<h3><u>Solution:</u></h3>Given that a line with slope 3 passes through point (0, 10)
To find the y-coordinate of the point on the line with x-coordinate 2
Which means the point is (2, y)
Let us find the required y co-ordinate using slope formula
<em><u>The slope of line is given as:</u></em>
For a line containing points and
is given as:
Given that slope "m" = 3
Substituting the values we get,
Thus the y-coordinate is 16
The equation of line that passes through the points (-3,-1) and
(-6,3) is:
Step-by-step explanation:
Given points are:
(-3,-1) =(x1,y1)
(-6,3)=(x2,y2)
The slope-intercept form of equation of line is:
We have to find the slope first
Putting the value of slope in the slope intercept form
To find the value of b, putting the point (-3,-1) in the equation
Putting the values of b and m
The equation of line that passes through the points (-3,-1) and
(-6,3) is:
