Math question down below
Kipish [7]
Answer: 6928

----------------------------------------------------------

Explanation: 

We have two areas we need to find: The area of the trapezoid and the area of the rectangle. Let's call these areas A1 and A2.

Area of Trapezoid = (height)*(base1+base2)/2
A1 = h*(b1+b2)/2
A1 = 80*(150+100)/2
A1 = 80*250/2
A1 = 20000
A1 = 10000

Area of Rectangle = (length)*(width)
A2 = L*W
A2 = 48*64
A2 = 3072

Subtract the two areas (A1-A2) to get the difference D
D = A1 - A2
D = 10000 - 3072
D = 6928

This difference D is exactly equal to the shaded area.

To investigate if there is an association between eating red meat and the health of individuals, researchers used data from a na
Reika [66]

Answer:

a) Observational study

b) No

c) No

-Eating habits

-Age

-Health hystory

Step-by-step explanation:

Hello!

An observational study is one where the investigator has no control or intervenes on it. He just defines the variable of interest and merely collects and documents the information. These types of studies are usually made as precursors to a more formal experimental study, to have an idea of what's to be expected from the population.

In this example, the researcher merely took the information of interest from the survey that was taken. The researcher did not intervene in any way in the experiment. Because of the lack of intervention from the researcher, it is not valid to use the conclusions of this experiment to generalize to all American adults. For instance, it is not sure that the sample is representative, all people responding to the survey may be healthy or have certain eating habits. This also shows that many confusing factors are not taken into account like:

-eating habits (from eating healthy to extreme cases like being vegetarian/vegan or eating only fast food)

-age, the age range is not defined, if the sample is taken from surveys answered by people in their early 20s it will be different in both eating habits and health information as if the interviewees are in their 30s or 40s

-before health issues, there can be other health conditions that may be affecting the interviewees.

I hope it helps!

On field day, Breanna long jumped 62 inches, Myquisha jumped 5 feet 4 inches, and Ariana jumped 1 yard, 2 feet, 7 inches. Which
ella [17]
Let’s convert all their jumps into inches.

Breanna’s is already in inches (62)

Myquisha jumped 5 feet 4 inches
There are 12 inches in a foot, so

5 feet * 12 inches= 60 inches

Then add the 4 inches
60+4= 64
So Myquisha jumped 64 inches.


Ariana jumped 1 yard, 2 feet, 7 inches

1 yard is equal to 3 feet.

So, she jumped 5 feet 7 inches

12 inches in a foot, so
5*12=60 inches

Add the 7
60+7= 67 inches

So Breanna jumped 62, Myquisha 64 and Ariana 67

In order of shortest to longest:

Breanna, Myquisha, Ariana
