Which description best describes the association between the years and population in this scatter plot?

Answers

Answer:

"moderate negative"

Step-by-step explanation:

 When two variables are correlated, a tendency, negative or positive, can be distinguished in the dispersion chart.

When the trend is positive it means that one variable increases when the other also increases.

When the trend is negative it means that one variable decreases as the other increases ..

The relationship between both variables can be strong or weak.

If the relationship is strong, the points in the scatter diagram will increasingly resemble a line (if it is a linear relationship).

If the relationship is weak, the points will be more and more scattered without any relation between them.

In this case it is observed that when the years increase the population decreases. Therefore it is a negative relationship. The distribution of the points resemble moderately to a straight line. Therefore, the correct option is "moderate negative"

Write an expression that can be used to multiply 6x198 mentally.

Answers

assuming you meant 6x198 do a mental sum for 6x200 (1200) then subtract 6x2(12)to give you 1188
In this problem, we are asked to give an expression that can be used to mentally multiply 6 and 198. In order not to go through the rigorous multiplication, we can estimate 198 to 200, that is 6 *200 equal to 1200. Since there is a 2*6 excess or 12 then we subtract: 1200 -12 equal to 1188.
