Answer:
x is 7 8
Step-by-step explanation:
y is 5 6
Answer: They can recieve about 2.
Exact answer: 2.5
Step-by-step explanation:
If you divded 100 by 40, you get 2.5
Since there are 20 students in each AM and PM classes. you add 20 and 20, which is 40, then you divided by 100 which is 2.5
That has a y intercept at y=-1. For every one block to the right we go three blocks up, so that's a slope of 3/1=3. So in slope-intercept form our equation is
y = 3 x - 1
Answer: third choice
Answer:
10 boys
Step-by-step explanation:
6:2 simplfies to 3:1 30 / 3 = 10
30:10 simplfies down to 6:2
One of the major advantage of the two-condition experiment has to do with interpreting the results of the study. Correct scientific methodology does not often allow an investigator to use previously acquired population data when conducting an experiment. For example, in the illustrative problem involving early speaking in children, we used a population mean value of 13.0 months. How do we really know the mean is 13.0 months? Suppose the figures were collected 3 to 5 years before performing the experiment. How do we know that infants haven’t changed over those years? And what about the conditions under which the population data were collected? Were they the same as in the experiment? Isn’t it possible that the people collecting the population data were not as motivated as the experimenter and, hence, were not as careful in collecting the data? Just how were the data collected? By being on hand at the moment that the child spoke the first word? Quite unlikely. The data probably were collected by asking parents when their children first spoke. How accurate, then, is the population mean?
