Step-by-step explanation:
Here is my table of points:
Answer:
(C) x^3+11x^2+34x+24
Step-by-step explanation:
The volume of a rectangular prism is V=lwh
x+4=L
x+1=W
x+6=H
Thus:
(x+4)(x+1)(x+6)
(x^2+5x+4)(x+6)
x^3+5x^2+4x+6x^2+30x+24
x^3+11x^2+34x+24
Therefore, the correct answer is (C) x^3+11x^2+34x+24
Because the triangle is an equilateral triangle, you know that all of the angles are equal to 60°. That means that you can use trigonometry to find the height, which would be sin(60) × 20 = 17.32.
Again, because it is an equilateral triangle, all sides are equal as well, meaning that the base is also 20cm. To find the area of the triangle, we must do (20 × 17.32)/2 = 173.2cm^2, which is the area.
I hope this helps!
I think the group 2 survey is likely to be biased towards people who are not too keen on zoos since all the values are small.
From group 1 and 3 the mean number of visits are
(4 + 10 + 6 + 3 + 8 + 7 + 9 + 3 + 4 + 7) / 10
= 61/10
mean = 6
