Students want to conduct an experiment to determine how road construction impacts the amount of PM in the air. They spread vasel

ine onto the bottom of six petri dishes and placed them at various distances from a road construction site and an existing road. The first three dishes were placed 50, 100, and 200 yards from the road construction site. The second group of dishes were placed 50, 100, and 200 yards from an active road (not under construction).

The control group and the dependent variable are respectively; will be the 3 dishes placed on the road not under construction and the 3 dishes placed on the road construction site

<h3>What is a control Group?</h3>

A control group in an experiment is that which is made up of participants that do not receive the experimental treatment.

From the opening paragraph, it means when we are conducting an experiment, these people in the control group are randomly assigned to be in this group and as such they also closely resemble the participants or the individuals who receive the treatment.

In this question, the control group will be the 3 dishes placed on the road not under construction

The dependent variable is one that depends on other variables or constraints in an experiment. In this question the dependent variable will be the 3 dishes that were placed in the road under construction.

Integrate from neg 1 to 1
kompoz [17]
First, we need to take the integral of ∛x+2 which is the same as x^1/3+2. To integrate the first part, we add one to the exponent and multiply by the new exponent's reciprocal to get 3/4*x^4/3. Then, the 2 would become a 2x. Now, we are finding the value of 3/4*x^4/3+2x from -1 to 1. To do this, you plug in the top value (1) first, and then subtract the result of plugging in the lower value (-1): [3/4*1^4/3+2(1)]-[3/4*(-1)^4/3+2(-1)]. This would be simplified to [3/4+2]-[3/4-2]. After distributing the negative, it becomes 3/4+2-3/4+2 or simply 4.
