A. Categorical
b. I think walking group (I’m not sure)
c. Bar graph
There are a total of 297 students in the 7th grade. Rough estimates would say that about half of that number are boys and half are girls. Asking only 50 random girls would be biased because not only would it not be all of the girls (the number of girls would be around 148 or 149) but it would also be ignoring the roughly 148 to 149 boys there are on estimate. The sample would be biased because it would be ignoring the opinions of more than half the seventh grade.
Answer:
Step-by-step explanation:
First find the place that is the thousandth place. That would be the 3 then you will look beside the 3 to see if their is a number bigger than five. If there is then you would add whatever number to make the number 10. In this case their is not so you would instead look at the three and replace all the numbers to the right of three ( don’t change three though) and make them zeros. So that will leave you with 299.2130 rounded to the nearest thousandth.
Answer: graph D
<u>Step-by-step explanation:</u>
graph A) The equation is y = x
graph B) The equation is y = -x² + 2
graph C) The equation is x = y²
graph D) The equation is y = 2
Which equation does not have an "x" in it? <em>D</em>
Therefore, the y-value is not dependent on an x-value.
