To start with, convert 52 feet into metres
1 Feet= 0.3048
52 feet= ?
The number of meters= 52*0.3048
The number of meters= 15.8496 metres
The school need to add a further 1.8496 metres
So if the main question is 9q x 3 it would equal 27q
3 + 3 - 3 / 3 = 5
3 + 3 + 3 - 3 = 6
3 + 3 + 3 / 3 = 7
3 * 3 - 3 / 3 = 8
Use symmetry and find z so that probability is:
(100-39)/2
=61%
=30.5%~0.305
From the z-table:
z=-0.51
Answer: -0.51
Answer:
80
Step-by-step explanation:
Triangles angles measure 180 degrees when added.
You have 2 at 50 which makes 100 degrees.
180 - 100 = 80 degrees
