Answer:
Y = 0.09X1 - 167.40
Step-by-step explanation:
Year (X) : 2000, 2004, 2006, 2007, 20008
Population (millions) (Y) : 7.08, 7.48, 7.64, 7.71, 7.77
Using technology, the regression model obtained is :
Y = 0.09X1 - 167.40
With a slope of 0.09 and intercept of - 167.40

Answer:
15 miles
Step-by-step explanation:
9 miles is 60% of the total
We can translate this to an equation. Remember:
- "IS" means "EQUAL"
- "OF" means "MULTIPLICATION"
- Percentage should be converted to decimal first by dividing by 100
- Let total be t
60% will be 60/100 = 0.6
Now, translating the word problem into an equation:

Now, we solve for total (t):

Hence, she ran 15 miles all week
