700% increase.
Step-by-step explanation:
The duration was 3 decades, or 30 years. The population starts at 100%, then doubles to 200% (decade 1), then 400% (decade 2), then 800% (decade 3).
800% - 100% = 700%
Answer:
240 meters^2
Step-by-step explanation:
Area of a triangle is 1/2b*h. (b=base, h=height). To solve you plug in the values 30 as b and 16 as h and then multiply to get 240.
Answer with explanation:
Given : The computed r -value = 0.45
Sample size : n=18
Degree of freedom : 
Now, the critical value for Pearson correlation coefficient for a two-tailed test at a .05 level of significance will be :
( by critical correlation coefficient table)
Since , 
i.e. 0.45>0.468 , then we say that his Pearson correlation coefficient is not significant for a two-tailed test at a .05 level of significance.
I believe it’s letter A tho no cap
