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.

The maximum pounds of cheese that Ariana can buy is 8

Step-by-step explanation:

Let

x ---> the amount of cheese In pounds, that Ariana can buy

we know that

The cost of 3 loaves of bread plus the cost of the cheese must be less than or equal to $50

The inequality that represent this situation is

$3(3.36)+4.99x\leq 50$

$10.08+4.99x\leq 50$

solve for x

subtract 10.08 both sides

$4.99x\leq 50-10.08$

$4.99x\leq 39.92$

divide by 4.99 both sides

$x\leq 8$

Therefore

The maximum pounds of cheese that Ariana can buy is 8

Which two points in the graphed function have an average rate of change of 5?

serious [3.7K]

Answer:

B. points A and B

Step-by-step explanation:

"Rate of change" is just a fancy name for slope.

The question asks for points on the graph having a slope of 5. We know a slope of 5 is a positive (goes up from left to right) and it's quite steep.

By looking at the graph, we see that to have a slope of 5, it has to take place in the first half of the graph.

Let's look at the possible options:

A. Points D and F: From point D to point F, you're going down, so the slope is negative. NO

B. Points A and B: goes up, pretty steep. Let's calculate the slope.

Point A: (2,1), Point B: (3,6)

Slope = (6 - 1) / (3 - 2) = 5 / 1 = 5

We found it!

C. Points B and C: goes up, pretty steep too. Let's calculate the slope:

Point B: (3,6) , Point C: (4,9)

Slope = (9 - 6) / (4 - 3) = 3 / 1 = 3, NO, not the slope we're looking for

D. Points C and E: goes down, NO, not what we want.
