<h3>
Answer: 45/121</h3>
=========================================
Work Shown:
2 blue, 4 red, 5 green
2+4+5 = 11 total
P(blue) = probability of getting one blue marble
P(blue) = (number of blue)/(number total)
P(blue) = 2/11
A = P(2 blue) = (2/11)*(2/11) = 4/121
P(red) = 4/11
B = P(2 red) = (4/11)*(4/11) = 16/121
P(green) = 5/11
C = P(2 green) = (5/11)*(5/11) = 25/121
Add the values of A,B, and C to get the probability of getting two of the same color
A+B+C = 4/121+16/121+25/121 = 45/121
This is approximately equal to 0.3719 which is roughly a 37.19% chance of happening
Side note: we can add A,B, and C because they are mutually exclusive events.
Answer:
A; y- 4 = -2(x + 1)
Step-by-step explanation:
Here, we want to find the equation of the given line
The general form
is ;
y = mx + c
c is the y-intercept which is 2
So we have
y = mx + 2
The x-intercept where y = 0 is 1
Thus;
0 = m(1) + 2
0 = m + 2
m = -2
So the equation of the line is
y = -2x + 2
We can rewrite this in the point-slope form as:
y - 4 = -2(x + 1)
Answer:
y= -5/12x - 11/12

Answer:
She will need approximate 
of plastic border
Step-by-step explanation:
we know that
The circumference of a circle is equal to
In this problem we have
substitute
----> exact value of the length of plastic border
assume
---> approximate value of the length of plastic border
