Answer:
The answer is D. An observational study
Step-by-step explanation:
The researchers are observing how different diets in the cattle affects their body composition. They are not counting a population or anything so it is not a census. It is not a sample survey because they aren't asking cows and it is not an experiment because they are not changing or testing anything. They are just viewing meaning it is an observational study.

The map below shows the locations of the houses of Maria Reese and Paul.what are the coordinates of Steve's house who lives 2 miles form Paul and 1 mile form Reese. Please help
Answer:
Coordinates of Steve's House are S (3,2)
The required coordinate of the Steves's house is (3,2).
The map below shows the locations of the houses of Maria Reese and Paul, coordinates of Steve's house who lives 2 miles from Paul and 1 mile from Reese is to be determined.
Coordinate, is represented as the values on the x-axis and y-axis of the graph
Here,
Since Steve's house lives 2 miles from Paul's, So the Y coordinate of Steve's house will raise to 2 more than the Y coordinate of Paul, So Y = 0 + 2 = 2
Now, Steve's house lives 1 mile from Reese x coordinate of Steve's house will raise to 1 more than the x coordinate of Reese, So X = 2 + 1 = 3
Thus, the required coordinate of the Steves's house is (3,2).

Give your answer correct to 1 decimal place.
Answer:
Step-by-step explanation:
reqd. rate=(1.6)×47÷34≈2.2 questions per minute.
The required rate to complete the question in 34 minutes is given as 2.2 questions per minute.
What is the rate of change?Rate of change is defined as the change in value with rest to the time is called rate of change.
As mentioned in the question, in homework rate of doing questions is 1.6 questions per minute.
It took 47 minutes to complete the whole expression,
Total questions in the homework given by,
Total question = rate × time
Total question = 1.6 × 47
Total questions ≈ 75 questions
Now,
If the time to complete the question is 34 minutes, the rate required is given by,
Rate = total question/time
Rate = 75/34
rate = 2.2 questions per minute.
Thus, the required rate to complete the question in 34 minutes is given as 2.2 questions per minute.

what is the value of x? Help asap please
Answer:
x = 30
Step-by-step explanation:
A triangle's angles add up to 180
Also, angles on a straight line add up to 180
180-100 = 80
80+70=150
180-150=30
Answer:
x = 30
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
100° is an exterior angle of the triangle, then
x + 70 = 100 ( subtract 70 from both sides )
x = 30

Use proportional reasoning to determine the value of a in the proportion shown below.
a=1
a=25
a=10
a=15
Answer: a = 10
Step-by-step explanation:
3/5 = a + 5/25
Multiply both sides by 25 to get rid of it:
3/5 * 25 = 25(a + 5) /25
15 = a + 5
a = 15 - 5
a = 10

If the measure of angle 1 is 110° and the measure of angle 3 is (2x+10)", what is the value of x?
x=50
Step-by-step explanation:
angle 1 and 3 are corresponding angles that menas they equal the same
so set it up like this 2x+10=110 solve for x
move over the 10, subtract 10 from 110 you get 100 and divide by 2
you get 50.
=================================================
Explanation:
Angles 1 and 3 are vertical angles which are congruent.
angle 1 = angle 3
110 = 2x+10
2x+10 = 110
2x = 110-10
2x = 100
x = 100/2
x = 50
5x + 7 (-7) = 2x + 6 (-7)
What property is being shown above?
O Multiplication Property of Equality
Division Property of Equality
O Addition Property of Equality
