Answer: The scatterplot shows a positive correlation because the values of y increase as the values of x increase.
Which of the following is the best approximation of the correlation coefficient for the data displayed in the scatterplot? 0.5
9 miles is = 60% of the distance she ran all the week.
9 = 60% of x.
9 = 0.60 * x.
0.6 x = 9 . Divide both sides by 0.6.
x = 9 / 0.6
x = 15.
Total distance = 15 miles.
N={1,2,3,4,5,6,....}
ElF={5,15,25,35,45,55,65,75....}
so let natural numbers to be n, so
a)count the distance between the numbers
b)add or subtract extra values
10n-5 would be one to-one correspondence.
Ticket cost = $220
discount = 10%
discount = 10/100 x 220=$22
total cost of the ticket is 220-22=$198
service charge is 10.5% of the total amount
service charge is 10.5/100 x 198=$20.79
you will pay 198 + 20.79= $218.79
33 hrs. Because 678.25-97.75= 580.5 and when you divide 580.5 by 17.80 you get 32.61 and you round that up to get 33 hrs
