Answer:
∛50 cm, 2∛50 cm, 3∛50 cm
Step-by-step explanation:
V= wlh
V=300 cm³
w= 1/3l
h= 2/3l
---------
- l*1/3l*2/3l=300
- 2/9l³=300
- l³= 1350
- l= ∛1350= 3∛50 cm
- w= 1/3*3∛50= ∛50 cm
- h= 2/3*3∛50= 2∛50 cm
The z-score corresponding to a cumulative area of 1 - 0.0122 = 0.9878 is 2.25.
Therefore the z-score corresponding to a cumulative area of 0.0122 is the negative of 2.25 = -2.25.
The answer is C. For sure
In d ratio 5:9 which equals 5+9=14
the total female performers is 63
For men = 5/14*63=5/2*9
=45/2 =22.5
The men would be about 22.5 in the dance recital
