Step-by-step explanation:
Your table is a little weird, so I will try my best:
a) A linear regression equation for the line of best fit would be y-hat = 0.018x - 24.5111 where y-hat is the predicted value for the recorded weight gain (in pounds) and x is the additional daily caloric intake. You can put the data into lists and use the LinReg function on the TI-84 to get this equation.
b) It seems that as the pony's additional calorie intake increases, the weight gain also increases in pounds
c) Set x equal to 2300 and solve for y-hat:
y-hat = 0.018x - 24.5111
y-hat = 0.018(2300) - 24.5111
y-hat = 41.4 - 24.5111
y-hat = 16.8889
So our predicted value for the weight gain based on an additional 2300 calorie intake is 16.9 pounds.

Answer:
27
Step-by-step explanation:
firstly we know we get 5 hour free so we know that when we add our total it will go up by 5. an easy way to do the equation is to take 45 and divide by two because we are essentially paying two of our 45 dollars every hour. this means that we will get half the amount we pay in hours. 45/2 =22.5 (do not round up because you will only get what you pay for and if you cant pay for a full hour you just do not get it) 22+5=27. so you get 27 hours of internet.
