ludmilkaskok [199]

Answer:

5

Step-by-step explanation:

To find the median number of

3 7 5 2 4 2 53 6 9 7 7 3 5 2 7 3 2 2 7

Number them from least to greatest

2 2 2 2 3 3 3 4 5 5 6 7 7 7 7 7 9 53

Since this isn't an even numbered set, all we do is cancel each number out equally on both sides until only one number which should be in the middle is left. This gives you an answer of 5

Hope this helps!

Timothy has a fenced-in garden in the shape of a rhombus. The length of the longer diagonal is 24 feet, and the length of the sh
Rzqust [24]
One property of the diagonals of a rhombus is that they are perpendicular bisectors of each other. So 4 congruent right triangles will be formed when you draw the two diagonals. Considering one right triangle, we can solve for the two sides by dividing them by 2.
24 ft/ 2 = 12 ft
18 ft/ 2 = 9 ft

Using the Pythagorean Theorem, we can now solve for the hypotenuse which is the side of the rhombus.
side = √(12²+9²) = 15 ft

The answer is B.
