The data represents the body mass index? (bmi) values for 20 females. construct a frequency distribution beginning with a lower

class limit of 15.015.0 and use a class width of 6.06.0. does the frequency distribution appear to be roughly a normal? distribution?

Given the data below <span>representing the body mass index (bmi) values for 20 females.
17.7     33.5     26.9     22.7     22.2     29.9     23.6     18.3     27.7     23.4     19.2     25.9     22.9     37.7     31.6     28.1     44.9     31.6     25.2     23.9

From the data above, we construct a frequency distribution beginning with a lower class limit of 15.0 and use a class width of 6.0 as follows:

Class iinterval: 15.0 - 21.0   21.0 - 27.0   27.0 - 33.0   33.0 - 39.0   39.0 - 45.0
Frequency:              3                  9                  5                   2                  1

From the frequency table, it can be seen that the frequencies started low, increased to a point and then decrease. It can also be seen that the highest frequency of the data is not at the center of the distribution, so the distribution is not symetric.

Therefore, the frequency distribution does not appear to be roughly a normal distribution, because, "although the frequency start low, increase to some maximum, then decrease, the distribution is not symmetric."</span>

Candace has $20 more than Amar. Their combined money totals $95. Write a system of equations represents this situation
STALIN [3.7K]

Answer:

Candace has $57.5 and Amar has $37.5.

Step-by-step explanation:

x+(x+20)=z

x+20=y

x+y=z

--------------

2x+20=95

2x=95-20

2x=75

x=75/2

x=37.5

37.5+20=y=57.5

What is the domain and derivative of f(x)=ln(2xsqrt(2+x))?
wolverine [178]
For domain 2x sqrt(2+x)>0
x>0,2+x>0,x>-2 combining 
we get x>2
f'(x)=[1/{2x sqrt(2+x)}][{2x/(2 sqrt(2+x))}+2 sqrt(2+x)]
