If Jerry, Joe, and David each get 1/3rd of a pizza, how can you express it as an integer?
Trick question - you can't! 1/3rd is 0.3 (with the 3 repeating) which can't be an integer
Suppose
is even, i.e. there is some integer
such that
. Then
where
is just some other integer. Therefore
is odd, proving the contrapositive, and so the original statement is also true.
Answer:
Answer/Step-by-step explanation: A. If a scatter plot shows an upward trend, it means there is a positive correlation between the x and y variables. That is, as one variable increases, the other also increases. The value of correlation coefficient, r, would be a positive value. Also, when the data points plotted are fairly far apart or moderately spread out along the line if best fit, the value of the correlation coefficient would be far from -1 but also far from 1. Therefore, if a computer software gives us a correlation coefficient of, r = 0.51, it is most likely an accurate value for the given data because it shows a positive correlation with data points moderately spread out and farther apart along the line of best fit. B. A scenario that can be written as a casual relationship for pumpkins picked can be: Number of pumpkins picked versus the amount of nutrient given per kg of fertilizer applied.

Answer:
B. The weather on a particular day a year from now
Step-by-step explanation:
We can only predict the weather in the near future, not long term or all time. The rest of the answer choices are predictable. We will always know the age of a person 10 years from now, we can predict the rating of the movie if we preview and watch it, and if a student studies enough/not enough we can predict the type of grade they will get on a test.
