Step-by-step explanation:
When you reflect a point across the y-axis, the x-coordinate gets multiplied by -1 and the y-coordinate remains the same.
A(-3, -2) => B(3, -2).
The number that is filled in the blank is 3.
Answer:
44 units²
Step-by-step explanation:
For triangles: (bases and heights of both triangles are equal)
Base = 4 units, height = 3 units
For trapezoid:
Base 1 = 5 units, base 2 = 3 units, height = 8 units
Area of figure = Area of two triangles + Area of trapezoid
= 2 *1/2 * base * height + 1/2(base 1+ base 2) *height
=4*3 + 1/2(5+3)*8
= 12 + 8*4
= 12 + 32
= 44 units²

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.
