alexgriva [62]

Answer:

Should be something along the lines of:

3,450 = 326x - 310

Step-by-step explanation:

First, let's start with the number of years. Assume the number of years is x. 3262 greenhouses amounts to about 326 greehouses/year. The other number was the existing greenhouses, but we want just how many greenhouses that were built, per the subtraction sign.

Hope this helps!! : )

Sorry if I am wrong, haven't done equations in a while.

Concerned about graffiti, mayors of nine suburban communities instituted a citizen community watch program. community monthly in
lesya [120]
The data are reported in the attached table.

We define the null hypothesis H₀ as the statement that is believed true until we prove it wrong with the test.
We define the alternative hypothesis H₁ as the statement we want to conclude with our test.

The difference in graffiti before (B) and after (A) will be:
d = A - B.

If the graffiti declined, it means that A will be smaller than B, therefore d should be negative.

Therefore we can set:
H₀ : μd  ≥ 0
H₁ : μd < 0 

The equal sign would mean that the number of graffiti incidents remained constant, therefore it is part of the null hypothesis.

Therefore the correct answer is B) H₀: μd ≥ 0 versus <span>H₁</span>: μd < 0

For the first interval (-1, 2), f(-1) = f(2), which means that the average rate of change on that interval is zero, so the correct option is A.

<h3>Over which interval the rate of change is zero?</h3>

For a function f(x) we define the average rate of change over the interval (a, b) is defined as:

R = (f(b) - f(a))/(b - a)

Here the function is:

f(x) = x^2 - x  -1

And the rate of change will be zero on an interval (a, b) if and only if:

f(b) = f(a).

Notice that the first interval is (-1, 2)

f(-1) = (-1)^2 - (-1) - 1 = 1 + 1 - 1 = 1

f(2) = 2^2 - 2 - 1 = 4 - 2 - 1  =1

Then f(-1) = f(2), which means that the average rate of change on that interval is zero, so the correct option is A.
