Conditional frequency:A two-way table (also called a contingency table) is used to examine relationships between categorical variables. ;-;
Basically, this problem wants you to solve the area of the trapezoid given those dimensions, then multiply this to the unit cost to determine the total cost. The formula for the area of trapezoid is written below:
A = (a+b)h/2, where a and b are the lengths of the two bases
A = (15+9)(10)/2 = 120 cm²
Total Cost = 120 cm² * $0.80/cm² = <em>$96</em>
Answer:
65, 123.79
Step-by-step explanation:
Since point Z is where the perpendicular bisector of the three sides of triangle GHJ intersect, point Z is the circumcenter. Circumcenters are equidistant from all three vertices, so GZ, JZ, and HZ all have equal length. Therefore ZJ is 65.
Next, look at triangle ZLJ and notice that it is a right triangle with legs 16 and x long and the hypotenuse 65 long. Using the Pythagorean Theorem, 16^2 + x^2 = 65^2, we learn that x, the length of LJ, is approximately 60.79. Add this with 63 to get 123.79.
