Answer:
See below
Step-by-step explanation:
B) The correlation coefficient is
, which can be determined by plugging the data into a TI-84 calculator.
C) A correlation coefficient of
indicates that the correlation between the independent and dependent variable (x and y in this case) is moderately strong with a positive correlation. The closer
is to 1, the stronger the positive correlation. The closer
is to -1, the stronger the negative correlation. If
is closer to 0, then there's no correlation.
Quadrant 3 will have a negative x and a negative y........so ur answers are :
A and C
If 4 lbs of potatoes cost 6.78...then 1 lbs of potatoes cost 6.78/4 = 1.695...rounds to 1.70 per lb
Answer:

Step-by-step explanation:
y = 4 is a horizontal line which would be parallel to the x axis
Answer:
46.2 square inches
Step-by-step explanation:
A parallelogram is a quadrilateral (4 sided closed figure) with 2 pair of parallel sides.
The diagram shown is a parallelogram.
Top and Bottom are parallel lines,
both sides are parallel lines (left and right).
The area for a parallelogram is given by:
Area = Base * Height
In the given figure, the base is clearly given as 4.2 inches
The height (perpendicular distance from base) is given as 11 inches.
<em><u /></em>
<em><u>So, basically we do not need the 11.7 inches length of side given.</u></em>
<em><u /></em>
Now, lets compute the area:
Area = base * height = 4.2 * 11 = 46.2 square inches
