inches and
inches.
Let x denotes the height of women.
Since 1 feet = 12 inches
5.5 feet =
inches
Then, the z-score corresponds to x=66 inches will be :-
![z=\dfrac{66-64.2}{2.8}=0.642857142857\approx0.64](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7B66-64.2%7D%7B2.8%7D%3D0.642857142857%5Capprox0.64)
Hence, the z ‑score for a woman 5.5 feet tall = 0.64

Circumference of a cirxle formula:
2*pi*r=C
Pi and Circumference are given so lets plug those in,
2*pi*r=7.85
6.28318530718*r=7.85
Divide both sides with 6.28318530718
r=1.24936630327
Answer:

Step-by-step explanation:
Let the amount she had initially be x euros.
Then we have the equation:
x - 0.40x - 0.35x = 26.80
x - 0.75x = 26.80
0.25x = 25.80
Multiply both sides by 4:-
x = 107.20 euros.
