Answer:
2: 35 and 70
Explanation:
1. The LCM of 5 and 7: <em>35</em>
2. 35 * 2 = 70
3. 35 * 3 = 105, not 2-digit
So, the only 2-digit numbers that are multiples of both 5 and 7 are 35 and 70, so 2.

The given statement about the correlation between two variables is; False
<h3>Pearson's correlation coefficient </h3>
Pearson's correlation coefficient is the measure of linear correlation between two sets of data.
Pearson's r is always between the values of -1 and +1.
In that range, -1 denotes a perfect negative while +1 denotes a perfect positive relationship and 0 denotes the perfect absence of a relationship.
Finally, Pearson's r is symmetric and as such the correlation between two variables x and y must be the same as the correlation between y and x.
Thus, if the correlation between x and y is 0.8, then the correlation between y and x must be also 0.8 and not -0.8 as the question states.
