Answer:
Option (C)
Step-by-step explanation:
Let the relation between amount of money (m) and Time (t) is represented by the equation,
m = ct + b
Where c = Investment per week
b = Ben already had the amount before investment
From the question,
c = $5 per week
b = $100
Therefore, equation will be,
m = 5t + 100
If duration of the investment 't' = 8 weeks
Amount in the account after 8 weeks,
m = 5(8) + 100
m = $140
Option (C) is the correct option.
The dependent variable depends on the independent do depending on how many bags you buy, the price changes so for 5 bags the price is $15 and for 10 bags the price is $30

Answer:
a) No, since 80 is less than 2.5 standard deviations above the mean; b) Yes, since 80 is more than 2.5 standard deviations above the mean.
Step-by-step explanation:
For part a,
The mean is 70 and the standard deviation is 5. This means that 2 standard deviations above the mean is 70+5+5 = 80.
This means that 80 is not an outlier, as it is not more than 2.5 standard deviations above the mean.
For part b,
The mean is 70 and the standard deviation is 3. This means that 2 standard deviations above the mean is 70+3+3 = 76; 3 standard deviations above the mean is 70+3+3+3 = 79. 80 is more than this, so yes, it is an outlier.
