So,
If we add them together, we get
5 + 3 + 4 + 1 = 13
Since there are 4 blue chips, the probability would be 4 out of the total number of chips, or 4/13.
Answer:
I think complementary angles
Area = length x width
Area = 21 square cm
Width = x
Length = 3x + 2
21 = 3x+ 2 * x
21 = 3x ^2 + 2x
Subtract 21 from both sides:
3x^2 + 2x -21 = 0
Use the quadratic formula to solve for x:
-2 +/- sqrt(2^2-4*3(-21))/(2*3)
X = 7/3 and -3
A dimension can’t be a negative value so x needs to be 7/3
Width = x = 7/3 = 2 1/3 cm
Length = 3(7/3) + 2 = 9 cm
Check: 9 x 2 1/3 = 21
Dimensions: width 2 1/3 cm length 9 cm
4, 1, 5, 2, 3
The appropriate order is ...
(4) Open a compass so its width is more than half the length of the given segment.
(1) Without changing its width, use the compass to draw an arc above and below the given line segment from one of the segment"s endpoints.
(5) Again, without changing its width, use the compass to draw another pair of arcs from the other endpoint. One arc will be above the segment while the second arc will be below.
(2) Draw the point of intersection between the pair of arcs above the line segment and between the pair of arcs below the line segment.
(3) Use a straightedge to connect the intersection points between each pair of arcs.
