Answer:
We conclude that a researcher used simple random sample.
Step-by-step explanation:
We know that select a sample of five children from a class of 30, a researcher puts each child’s name on a slip of paper, then shuffles the papers in a hat and randomly picks five names.
We conclude that a researcher used simple random sample.
Because every children has an equal chance of being included in the sample.
I can’t understand the question can you write it more clearly?
<h2>Hello!</h2>
The answer is:
The coordinates of the midpoint are:
<h2>
Why?</h2>
We can find the midpoint of the segment with the given endpoints using the following formula.
The midpoint of a segment is given by:
We are given the points:
and
Where,
So, calculating the midpoint, we have:
Hence, we have that the coordinates of the midpoint are:
Have a nice day!
Answer: A
Step-by-step explanation:
A linear function is described as:
https://tex.z-dn.net/?f=f(x)%20%3D%20ax%20%2B%20b
When the value of x = 0, then you're left with
https://tex.z-dn.net/?f=f(x)%20%3D%20b
In this question, the speed of sound is the linear function while the temperature is the independent variable. When T = 0, you're left with
https://tex.z-dn.net/?f=S(0)%20%3D%20331.4
Which means the speed of sound in air when temperature is 0°C is 331.4m/s.
1.6*100/0.95=168% 1.6 to 0.95
0.95*100/1.6=59% 0.95 to 1.6
