Answer:
Option (D) : 1 / 4
Step-by-step explanation:
We know that :
Let's find the rates at which Melinda and Marcus are saving money and compare them.
Based on the table, we can see that Melinda originally had $75. Then she got $135 in 5 weeks. So the rate of saving money is (135–75)/5 = $12 per week.
This rate is unchanged for the next weeks. As we can see, she got $195 in the next 5 weeks. So she saved $60 more those 5 weeks, or the rate is $60/5 = $12 per week again.
So Melinda saved $12 per week.
As for Marcus, the equation tells us that the rate of saving money is $14 which is the coefficient in front of x.
Hence, t<span>he rate at which Melinda is adding to her savings each week is 2$
less than the rate at which Marcus is adding to his savings each week.</span>
Answer:
The predicted value of the year 18 is 107
Step-by-step explanation:
create a scatter plot for year and mean variables.
(<em>i have done that with Microsoft excel check the attachment from 1-3)</em>
Least square regression equation:
y = 9.3187x - 61.121
Predicted value of the lean 18
y = 9.3187 x (18) - 61.121
y = 107
The predicted value of the year 18 is 107
No it doesn’t because 16+16=32, +50 cents = 32.50
