<h3>
Answer: 13/28</h3>
========================================================
Reason:
The table shows he got 26 heads out of 26+30 = 56 coin flips.
26/56 = (2*13)/(2*28) = 13/28 is the empirical or experimetnal probablity of getting heads.
Side note: 13/28 = 0.4643 = 46.43% approximately which is fairly close to 50%
2.5x - 3 + 2x = 1.75x - 1.25x + 13
4.5x - 3 = 0.50x + 13
4.0x = 16
x = 4
Answer: 4
2. We'll assume those xs are in the numerator
(3/7)x - 1/4 + (3/7)x = (9/7)x - (3/7)x + 3/4 - 1
(6/7)x - 1/4 = (6/7)x - 1/4
0 = 0
That's always true.
Answer: Any x is a solution.
Answer:
30.594
Step-by-step explanation:
To find perimeter we need to find the length of all the sides
The coordinates are A(-3,4), B(7,2), C(6,-3), D (-4,-1)
To find the length of side , we use distance formula

Side 
Side 
Side 
Side 
To find perimeter we add all the sides
10.198 + 5.099 + 10.198 + 5.099= 30.594
the perimeter of the rectangle= 30.594
