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.

500 * 0.000000001 = 0.0000005 Giga seconds
Final answer:
500 seconds equates to 0.0000005 gigaseconds. This is determined by dividing 500 seconds by 1,000,000,000 seconds (the number of seconds in a gigasecond).
Explanation:
In the field of physics, the measure of time can be broken down into various units. The smallest unit is the second. Higher units include kiloseconds, megaseconds, and gigaseconds. One gigasecond (Gs) is equal to 109 seconds or 1,000,000,000 seconds.
To convert 500 seconds into gigaseconds, you need to divide 500 by 1,000,000,000.
So, 500 seconds = 500 / 1,000,000,000 Gs.
This calculation results in 0.0000005 Gs, which is your answer.

Step-by-step explanation: So for this problem it is important to know what a median is. The median is essentially the center number when everything is written out. So you want to take your line plot and write out each number on the bottom as many times as a dot appears above it. For this problem that would look like 6, 6, 7, 7, 8, 9, 9. Since you have seven numbers the center would be the 4th one. In ascending order out of these numbers the 7 occurs fourth thus giving you your answer.

Answer: y = -2x + 13.
Step-by-step explanation:
To find the equation of a line that passes through the points (4,5) and (2,9), we can follow these steps:
1. First, let's determine the slope of the line using the formula: slope (m) = (change in y) / (change in x). We can choose any point as (x1, y1) and the other point as (x2, y2) to calculate the slope.
Using (4,5) as (x1, y1) and (2,9) as (x2, y2):
slope (m) = (5 - 9) / (4 - 2) = -4 / 2 = -2
2. Now that we have the slope (-2), we can use the point-slope form of a line to find the equation. The point-slope form is given by: y - y1 = m(x - x1), where (x1, y1) is one of the given points and m is the slope.
Using (4,5) as (x1, y1) and -2 as the slope (m):
y - 5 = -2(x - 4)
3. Simplifying the equation further, we get:
y - 5 = -2x + 8
4. To obtain the equation in slope-intercept form, we can isolate y by adding 5 to both sides:
y = -2x + 8 + 5
y = -2x + 13
Therefore, the equation of the line that passes through the points (4,5) and (2,9) is y = -2x + 13.
Final answer:
The equation of the line that passes through the points (4,5) and (2,9) is y = x + 1.
Explanation:
To find the equation of the line that goes through the two given points (4,5) and (2,9), we can use the slope-intercept form of a linear equation, y = mx + b.
First, we need to calculate the slope (m) using the formula:
m = (y2 - y1) / (x2 - x1)
Substituting the values from the points, we get:
m = (9 - 5) / (2 - 4) = -2 / -2 = 1.
Next, we can substitute the slope and one of the given points into the equation to solve for the y-intercept (b).
Using the point (4,5):
5 = (1)(4) + b
b = 5 - 4 = 1.
Therefore, the equation of the line is y = x + 1.
