Answer:
Amounts in the intervall ![130 \leq c \leq 230](https://tex.z-dn.net/?f=130%20%5Cleq%20c%20%5Cleq%20230)
Step-by-step explanation:
We will take the variables c and s, where
c = amount to spend that month
s = savings of the month.
Since each month we save at least 100, we know that
![0 \leq s \leq 100](https://tex.z-dn.net/?f=0%20%5Cleq%20s%20%5Cleq%20100)
Moreover, we earn $250 per month and we spend $20 in a kayaking club, which tells us that
![250=20+s+c](https://tex.z-dn.net/?f=250%3D20%2Bs%2Bc)
and so
![230-s=c](https://tex.z-dn.net/?f=230-s%3Dc)
By multiplying by -1, the first inequality also tells us that
![-100 \leq -s \leq 0](https://tex.z-dn.net/?f=-100%20%5Cleq%20-s%20%5Cleq%200)
Consequently by adding 230 to the inequality, we get that
![230-100 \leq 230-s \leq 230\\\\\Rightarrow 130\leq c \leq 230](https://tex.z-dn.net/?f=230-100%20%5Cleq%20230-s%20%5Cleq%20230%5C%5C%5C%5C%5CRightarrow%20130%5Cleq%20c%20%5Cleq%20230)
What the answers choices?
The sample which is likely to produce the most valid result is Richard's sample because there was no statistical bias. Statistical bias is the systematic favoritism of certain individuals in the study. Just like what Adriana, Henry and Malik did in conducting their surveys, they choose people who are point of interest and also who are near them. In the way Richard conducted his survey, he used a random sampling technique, this is a method of selecting a sample from a population in such a way that every possible individual can be chosen and he doesn't know who these people are.
Answer:
Each child will receive 0.125 (or 12.5%) of the estate.
Step-by-step explanation:
If the surviving spouse gets one half of the estate, the other half have to be divided among the four surviving children.
So its 0,5 divided among the 4 surviving children. That is 0.125 or 12.5% of the estate.
Each child will receive 0.125 of the estate.
