Answer: it will take 35 more gallons.
Reasoning: multiply 17.5 by 3, then get the answer (52.5), finally subtract 17.5 by 52.5 and you should see how many more gallons needed. <3

What is the average rate of change of the function on the interval from x = 1 to x = 2?

neonofarm [45]

x=1 f = 10(5.5)(1) = 55

x=2, f = 10(5.5)(2) = 110

110-55 = 55

2-1 =1

55/1 = 55

average rate of change = 55

Answer:

I think these are the right answers. The answer to one is 32. The answer to two is 38.

1: 2[18-(5+3^2)/7]

2[18-(5+9)/7]

2[18-14/7]

2[18-2]

2 times 16 = 32

2: I used a calculator for this one.

Use the regression calculator to compare the teams’ number of runs with their number of wins. a 2-column table with 9 rows. colu

The equation of the trend line is ŷ = 0.15x - 23.21

<h3>How to determine the average rate of change of the trend line?</h3>

The points are given as:

hr =>808, 768, 655, 684, 637, 619, 613, 609, 563

w => 93, 94, 66, 81, 86, 75, 61, 69, 55.

Using a graphing calculator, we have the following calculation summary:

Sum of X = 5956
Sum of Y = 680
Mean X = 661.7778
Mean Y = 75.5556
Sum of squares (SSX) = 50569.5556
Sum of products (SP) = 7547.1111

The regression equation is represented as:

ŷ = bX + a

Where:

b = SP/SSX

b = 7547.11/50569.56

b = 0.14924

a = MY - bMX

a = 75.56 - (0.15*661.78)

a = -23.20961

This gives

ŷ = 0.14924X - 23.20961

Approximate

ŷ = 0.15x - 23.21

Hence, the equation of the trend line is ŷ = 0.15x - 23.21
