Step-by-step explanation:
Using it's concept, it is found that the average rate of change of the function from x = -1 to x = 5 is of -1.
<h3>What is the average rate of change of a function?</h3>
It is given by the <u>change in the output divided by the change in the input</u>.
In this problem, the output changes by -6(from 7 to 1) when the input changes by 6(from -1 to 5), hence the average rate is given by:
r = -6/6 = -1.

Answer: Many utility companies promote energy conservation by offering discount rates to ... who keep their energy usage below certain established subsidy standards. A recent EPA report notes that 70% of the island residents of Puerto Rico have reduced their electricity usage sufficiently to qualify for discounted rates.

It's clear that Kevin took (1/4)x.
Keith took (1/4)x -> kevin's amount
* 2 -> twice.
-1 -> 1 less.
So Kevin + Keith = (1/4)x + (1/4)x * 2 - 1 = (3/4)x - 1.
Answer:
a) There is suggestive evidence the velvet leaf seed is successful at weed control.
b) Lower bound: 3.699 Upper bound: 6.629
c) Since the confidence interval contains the average percent of seeds to be infected by the beetle (5.164), so we fail to reject the null hypothesis at the specified level of significance.
Step-by-step explanation:
