Hey there, x:252 miles, 1/4:18=x:52, from there we cross mutliply 18*x=1/4*252=18x=63, x=63/18=7/12=3.5. So, the anwer is 3.5 inches.
The answer to the question
Answer:
The probability distribution for x:"number of children per family for this income group" is:
![\text{P(x=0)}=0.15\\\\\text{P(x=1)}=0.35\\\\\text{P(x=2)}=0.45\\\\\text{P(x=3)}=0.05\\\\](https://tex.z-dn.net/?f=%5Ctext%7BP%28x%3D0%29%7D%3D0.15%5C%5C%5C%5C%5Ctext%7BP%28x%3D1%29%7D%3D0.35%5C%5C%5C%5C%5Ctext%7BP%28x%3D2%29%7D%3D0.45%5C%5C%5C%5C%5Ctext%7BP%28x%3D3%29%7D%3D0.05%5C%5C%5C%5C)
Step-by-step explanation:
With the information given we have the relative frequencies of each category.
We know:
![\text{P(x=0)}=0.15\\\\\text{P(x=1)}=0.35\\\\\text{P(x=2)}=0.45\\\\\text{P(x=3)}=0.05\\\\](https://tex.z-dn.net/?f=%5Ctext%7BP%28x%3D0%29%7D%3D0.15%5C%5C%5C%5C%5Ctext%7BP%28x%3D1%29%7D%3D0.35%5C%5C%5C%5C%5Ctext%7BP%28x%3D2%29%7D%3D0.45%5C%5C%5C%5C%5Ctext%7BP%28x%3D3%29%7D%3D0.05%5C%5C%5C%5C)
It’s usually takes a compound interest of 4%
4 and 1/2 years
Step-by-step explanation:
y = sqrt[3² + 3²] = sqrt18 = 3sqrt2.
