Answer:
¾
Step-by-step explanation:
More than 3: 9
P(more than 3) = 9/12 = ¾
Answer:
The solution is the point (0.5,-3)
Step-by-step explanation:
we have
----> equation A
----> equation B
Solve the system by substitution
Substitute equation B in equation A

Solve for x
Adds 5 both sides


Divide by 4 both sides

therefore
The solution is the point (0.5,-3)
<em>Verify your answer using the graph</em>
using a graphing tool
Remember that the solution of the system of equations is the intersection point both graphs
The intersection point is (0.5,-3)
therefore
The solution is the point (0.5,-3)

<h3>Answer:</h3>
w+x+y+z = 12
<h3>Explanation:</h3>
When right angle ADC is divided into three equal parts (trisected), each of those parts is 90°/3 = 30°. Thus, ∠CDB = ∠PBD = ∠PDB = 30°.
The sides of a 30°-60°-90° triangle are in the proportion 1 : √3 : 2. Hence BD = 2, and PD = PB = 2/√3 = (2/3)√3.
Then the perimeter of ∆BDP is ...
... perimeter ∆BDP = BD + DP + PB
... = 2 + (2/3)√3 + (2/3)√3
... = 2 + (4√3)/3 . . . . . . . . w=2, x=4, y=3, z=3
w + x + y + z = 2+4+3+3 = 12
