1st set = 4 letters
2nd set = 4x 4 = 16 letters
3rd set = 16 x 4 = 64 letters
4th set = 64 x 4 = 256 letters
5th set = 256 x 4 = 1,024 letters
6th set =1024 x 4 = 4,096 letters
7th set = 4096 x 4 = 16,384 letters
8th set = 16,384 x 4 = 65,536 letters
Each letter cost 2
Total cost = 65,536 x 2 = 131,072
60 miles because (20mph)((3hrs) = 60
Answer:
6%
Step-by-step explanation:
393/6550=0.06
0.06=6%
Answer:
Step-by-step explanation:
n = sample size = 5
a) Let us determine the sum





Now we can determine 




The estimate b of the slope β is the ratio of
and 


The mean is the sum of all value divide by number of values


The estimate a of the intercept is


General least square equation;

replace alpha by a = 3 and beta by b = 0.67 in general least equation
y = a + bx
195.9 + 0.67x
b)
<em>Scatter plot is shown in the attached file</em>
x is on the horizontal axis
y is n the vertical axis
The degree of freedom of regression is 1
because we use one variable s predictor variable

The degree of freedom of error is the sample size n decrease by 2

Total df is equal to the sum of seperate degree of freedom dfR and dfE
total df = 1 +3 4

Total SS =Syy= 45007.2
SSE + Total SS = SSR
= 45007.2 - 43146.9296
= 1860.2705
