Plz 30 points im desperate
loris [4]

Answer:

See below for answers and explanations

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.

Solve for b. 2/3 b + 5 = 20 - b
Arisa [49]

Answer:

b = 9

Step-by-step explanation:

Step 1: Add <em>b</em> on both sides (Addition Equality)

5/3b + 5 = 20

Step 2: Subtract 5 on both sides (Subtraction Equality)

5/3b = 15

Step 3: Divide both sides by 5/3 (Division Equality)

b = 9

Part 1

Answer: -9

---------------------------

Explanation:

Let's focus on evaluating   first. We need to look at the table and locate f(x) = 13. So we're looking in the f(x) row where 13 shows up. That's in the second to last column. Right above that we have x = 5

This means f(5) = 13 and   The inverse undoes the f(x) function. So the input x and output y values swap places. This is why we're reading the table in reverse.

<em>We can replace all of </em>f^{-1}<em> </em>(13)<em>  with 5 to go from </em>f^{-1} (f^{-1} (13))<em> to </em>f^{-1} (5)<em> </em>

<em>Then we repeat the process of using the table. Locate 5 in the f(x) row. This is in the last column. The value above that is x = -9.</em>

<em>So f(-9) = 5 and </em>f^{-1} (5)=-9

<em>Overall, </em>f^{-1} (f^{-1} (13))=-9

===============================================

Part 2

Answer:  -13

---------------------------

Explanation:

Same idea as before. Locate 8 in the f(x) row. The value above this is x = -13

<em>This means f(-13) = 8 and </em>f^{-1}(8) =-13
