Explanation
We are asked to compute the correlation coefficient using a graphing calculator
To do so, we have the following:
From the data plot above, we have the correlation coefficient as:
So the answer is 0.87 (to 2 decimal places)
Answer:
c. perpendicular line
Step-by-step explanation:
40/3 = 13.33 pounds per bag
160/13.33 = 12.00
they donated 12 bags.
Answer: cube
Step-by-step explanation:
Think of a box .... it has 4 sides, a top, and a bottom = 6 total sides
Which of the following statements are true for a rhombus? It has two pairs of parallel sides. It has two pairs of equal sides. It has only two pairs of equal sides. Two of its angles are at right angles. Its diagonals bisect each other at right angles. Its diagonals are equal and perpendicular. It has all its sides of equal lengths. It is a parallelogram. It is a quadrilateral. It can be a square. It is a square.
It would be 3.14(7)^2
Then 3.14*49
Multiply those two to get your area
