Ierofanga [76]

Answer:

a. A western diet is associated with higher blood pressure.

b. Eating a western diet increases blood pressure.

Step-by-step explanation:

Given that :

Three groups of 21 participants participated in an observational study.

         A

The raw vegan diet group  who sedentary and had been eating a low-calorie, low-protein vegan diet composed primarily of unprocessed and uncooked plant-derived foods for at least 2 years.

          B

The subjects in the endurance runners group who ran an average of 48 miles per week for an average of 21 years.

         C

The subjects in the western diet group consisted of sedentary and non-obese subjects who ate a typical western diet (characterized by high intakes of red meat, sugary treats, high-fat foods, and refined grains).

From the observational study; we can observe that the raw vegan diet group will improve the heart health, they possess high fiber content necessary for healing. They don't quite have any issues related to higher blood pressure.

The Endurance runners groups who ran for an average of 48 miles per week for an average of 21 years will have a better heart health and a reduction in the risk associated with higher blood pressure or other health related diseases.

But the western diet group  who ate a typical western diet (characterized by high intakes of red meat, sugary treats, high-fat foods, and refined grains) will have a variety of health complications all types of the foods being consumed. For example, high intake of red meat and sugary treats and high-fat food can result an individual to having diabetes. Because these food mention contains high  saturated fat which raises  the blood cholesterol . As a result high level of these cholesterols in the body can cause several heart complications and other health related diseases.

So from the aforementioned , we can concluded that :

option A and B were appropriate summary for the students statements.

Which is the best approximation of the solutions to the system of equations graphed below?
Neko [114]

According to the direct inspection, we conclude that the best approximation of the two solutions to the system of <em>quadratic</em> equations are (x₁, y₁) = (- 1, 0) and (x₂, y₂) = (1, 2.5). (Correct choice: C)

<h3>What is the solution of a nonlinear system formed by two quadratic equations?</h3>

Herein we have two parabolae, that is, polynomials of the form a · x² + b · x + c, that pass through each other twice according to the image attached to this question. We need to estimate the location of the points by visual inspection on the <em>Cartesian</em> plane.

According to the direct inspection, we conclude that the best approximation of the two solutions, that is, the point where the two parabolae intercepts each other, to the system of two <em>quadratic</em> equations are (x₁, y₁) = (- 1, 0) and (x₂, y₂) = (1, 2.5). (Correct choice: C)
