Identify the sample chosen for the study. The number of hours a group of 12 children in Mrs. Smith's kindergarten class sleep in a day. Answer2 Points The 12 children selected in Mrs. Smith's kindergarten class. All children in Mrs. Smith's kindergarten class. The number of hours children sleep.

Answers

Answer:

The 12 children selected in Mrs. Smith's kindergarten class.

Step-by-step explanation:

A sample is a representative part of a population on which a research is carried out.

The study In Mrs Smith's class was to find out the number of hours the children in Kindergarten Sleep in a day. Out of the total number of students, 12 were selected for observation. The 12 childen selected is therefore  a sample of the class.

Final answer:

The sample in the study refers to the 12 children in Mrs. Smith's kindergarten class. A sample is a subset of people selected from a larger group for study purposes. In this research, the data being analyzed only pertains to these selected individuals.

Explanation:

In this study, the sample chosen is the group of 12 children in Mrs. Smith's kindergarten class. This is because the data being collected and scrutinized is related to these particular individuals. In this context, 'sample' refers to the subset of people chosen from a larger group (the population) for research or study purposes. It is the set of individuals on which the study or experiment is conducted. In this case, the larger population could be considered all children in kindergarten, but the sample for the study is specifically the 12 children in Mrs. Smith's class, as the study only includes their sleep patterns.

If m = 8, how many solutions are there for the expression m - 8? what is it going to be? 0 ? 1 ? 2 ? or infinite ?

Answers

Answer:

The answer is m=8

Step-by-step explanation:

In order to determine the answer, we have to know that it means "solution".

In any expression where there is a variable, we can replace any value in the variable and we get a result. When we replace a value that it makes the expression equal to zero, that value is called "solution".

So in this case, we have to find a solution for "m":

m-8=0\nm=8

Finally, the solution is only one and it is 8.
Solutions for the expression:
(m - 8)

if m = 8, 
Solution for the expression m - 8 = 8 - 8 = 0.

So there is only 1 solution for the expression.

What is the 10th term of the geometric sequence 400, 200, 100...?

Answers

ANSWER

a_ {10} = (25)/(32)

EXPLANATION

The given geometric sequence is

400, 200, 100...

The first term is

a_1=400

The common ratio is

r = (200)/(400) = (1)/(2)

The nth term is

a_n=a_1( {r}^(n - 1) )

We substitute the known values to get;

a_n=400( (1)/(2) )^(n - 1)

a_ {10} =400( (1)/(2) )^(10 - 1)

a_ {10} =400( (1)/(2) )^(9)

a_ {10} = (25)/(32)

A+(-b) where a=4 and b=2

Answers

Answer:

The sum of a and (-b) is 2

Step-by-step explanation:

method 1:First, we take the negate(negative) of b to get -2. Then, we take the sum of 4 and -2 to get 2.

method 2: since adding a negative is the same as subtracting a positive, we get 4-2, which is 2.
