Answer:
a
SST = 1800
SSR = 1512.376
SSE = 287.624
b
coefficient of determination is 
What this is telling us is that 84.02% variation in dependent variable y can be fully explained by variation in the independent variable x
c
The correlation coefficient is 
Step-by-step explanation:
The table shown the calculated mean is shown on the second uploaded image
Let first define some term
SST (sum of squares total) : This is the difference between the noted dependent variable and the mean of this noted dependent variable
SSR(sum of squared residuals) : this can defined as a predicted shift from the actual observed values of the data
SSE (sum of squared estimate of errors): this can be defined as the sum of the square difference between the observed value and its mean
From the table




The coefficient of determination is mathematically represented as




The correlation coefficient is mathematically represented as

Substituting values


this value is + because the value of the coefficient of x in estimated regression equation(
) is positive
Answer:2.65
Step-by-step explanation:
The answer is 2.65
Answer:
im going to say c
Step-by-step explanation:
if its has 160 units and goes to half-life after 2 months im assuming it loses 1/2 of the units so in order for it to lose that many it will have to lose 40 units a month so i say its c after 10 months there will be less than 1 unit in the potion
hope this helps im sorry if im wrong have a blessed day :)
23/100×$640=147.2 is the answer
