Answer:
4.9%
Step-by-step explanation:
To find the percentage you first find the decrease in price, divide it by the original price then multiply it by 100.
(14. 44-13. 72)
= -------------------- ×100
14. 44
0. 72
= -------- × 100
14. 44
= 0. 72× 6. 925207759
= 4. 986149584
~ 4. 9
Given that the mean is 55 inches and Dave is 57 inches, he would have increased the mean of the height in the stem-and-leaf plot that the students were making. This is however is also dependent upon the central tendency that was used, in this case the central tendency is mean or average.
Answer:

Step-by-step explanation:
<u><em>The complete question is</em></u>
Given the quadrilateral is a rectangle, if LO = 15x+19 and QN = 10x+2 find PN
see the attached figure to better understand the problem
we know that
The diagonals of a rectangle are congruent and bisect each other
so

substitute the given values

solve for x

Find the length of PN
Remember that
----> diagonals of rectangle are congruent

substitute the value of x

therefore

Check the picture below.
so notice, their perimeter is the same, because the perimeter is just one rod anyway, and all rods are the same length, thus
