Her insurance premiums are 150 per month.....there is 12 months in a year....so in 1 year, her premiums totaled : (150 * 12) = 1800
she paid a $ 500 deductible
she paid 20% of $ 3000 for the accident..
0.20 * 3000 = $ 600
therefore, her total healthcare expenses for 1 yr totaled :
1800 + 500 + 600 = $ 2900 <==
Answer:
• Random sampling [ Probability and statistics method ]
Step-by-step explanation:
• This method is easier and saves time.
By probability, a person whose height is to be recorded will be chosen randomly. This will be done on approximately 40% members.
By statistical step, we'll feed results into distribution table. Then we'll find the mean height.
![{ \boxed{ \rm{mean \: height = \frac{ \sum \: f(n)}{n} }}}](https://tex.z-dn.net/?f=%7B%20%5Cboxed%7B%20%5Crm%7Bmean%20%5C%3A%20height%20%3D%20%20%5Cfrac%7B%20%5Csum%20%5C%3A%20f%28n%29%7D%7Bn%7D%20%7D%7D%7D)
• f of n is product of frequency and respective height bracket
• n is the number of samples.
