No it's not a reasonable conclusion. Correlation does not lead to causation. If two variables are linked, then they may affect one another or there may be another set of factors involved. There isn't enough info to know for sure. The fact that r = -0.7 is fairly close to r = -1 indicates there's moderately strong negative correlation, but I don't think it's strong enough in my opinion. More research is needed.
In short, the keyword "caused" as part of the claim is what makes it unreasonable. There is no way to know that not eating vegetables leads to high blood pressure. It may be true but again, more info is needed.
Blank hundredths equals 80 hundredths
It's the first one because the other three go pasted -6 which would make the problem not true.
Answer:
10.92
Step-by-step explanation:
1. Find all side lengths of this tetrahedron.
A to B is 2 units
A to C is 2 units
A to D is 2 units
B to C is square root of 8
B to D is square root of 8
C to D is square root of 8
See 3D distance formula attached below to get the answers above.
2. Find the area of the triangles
Triangle ACD can be calculated using Heron’s formula, which is also attached below.
Area of Triangle ACD is 2 units squared.
Area of Triangle ABD is congruent to the previous one so it is also 2 units squared.
Area of Triangle CBD is roughly 3.46 units squared.
Area of Triangle ABC is congruent to Triangle CBD so it is also 3.46 units squared.
Adding them altogether is 2 + 2 + 3.46 + 3.46 = 10.92
In this question, it is given that two of the dimensions are 3 cm and 9 cm . Let the other dimension be x cm .
And the surface area of the rectangular prism is given. Now we use the formula of surface area of prism, which is
Subtracting 27 to both sides,
Dividing both sides by 12
So the length of the remaining dimension is 6 cm .
