Answer:
5.5369
Step-by-step explanation:
tan(64) = 13/x
2.3478 = 13/x
Multiply both sides by x
2.3478x = 13
Divide both sides by 2.3478
5.5369 = x
Answer:
108ft³
Step-by-step explanation:
V=(base area) (h/3) = 81 (4
/3) =108ft³
Answer:
1. surface area, 2. volume. 3. surface area, 4. volume
Step-by-step explanation:
The stain means it's just the surface of the box, and not what can go in it.
the question is asking how many shoe boxes can fit IN
Answer:

B. The coefficient of determination is 0.1980, 19.8% of the variation is explained by the linear correlation, and 80.2% is explained by other factors.
Step-by-step explanation:
Previous concepts
The correlation coefficient is a "statistical measure that calculates the strength of the relationship between the relative movements of two variables". It's denoted by r and its always between -1 and 1.
Solution to the problem
In order to calculate the correlation coefficient we can use this formula:
On this case we got that r =0.445
The determinaton coefficient is just:

And we can put it on % and we got 19.8%. And represent the variation explained by a linear model. The best option on this case would be:
B. The coefficient of determination is 0.1980, 19.8% of the variation is explained by the linear correlation, and 80.2% is explained by other factors.
Since the explained variation is 19.8% and the remain 100-19.8= 80.2% is explained by other factors.
Answer:
M=7/8
Step-by-step explanation:
The equation used to solve this is yz-y1/x2-x1.
This applied to the problem would look like 9-2/3--5
Simplified this would be, 7/8 as your slope
