Answer:
73.5
Step-by-step explanation:
A=bh
10.5*7
73.5
P=2(l+w)
190=2[(2l+5)+l)
190=4l+10+2l
190=6l+10
180=6l
l=30
190=2(30+w)
190=60+2w
130=2w
w=65
The width of the rectangle is 65.
Answer

standard deviation is the deviation of the value from the target value.
the given question standard deviation of the students is more than that of the individual standard deviation of the heights of males and females because of the distribution of the entire class has more dispersion.
