Answer: The regression equation could have a positive or a negative slope

Explanation:

The coefficient of determination is marked as r^2. This is always positive because squaring a negative leads to a positive. Knowing something like r^2 = 0.7 does not tell us whether r itself is positive or negative, so we don't know if the regression line slope is positive or negative. We would need more info.

Write an inequality for the given statement the product of -3 and a number is no more than 15
Nata [24]

Answer:

-3n ≤ 15

Step-by-step explanation:

"No more than 15" means the number can be less than 15 or equal to 15, but it can't be more than 15.

"The product of -3 and a number"  "is no more than"  "15".

                          -3n                                        ≤                 15

-3n ≤ 15
