what is the median age of the presidents at their death?
a.
69
c.
68
b.
67.5
d.
70

Option a is right

Step-by-step explanation:

The given data is already in ascending order as

46

58

64

68

Since they are 38 entries we take the middle entries as 19 and 20 and find the average of them.

Median =(68+70)/2 =69

Hence option a is right.

the median age of the presidents at their death is

a.  69

Step-by-step explanation:

age at which 38 U.S. Presidents died.

46 ,58 ,64 ,68 ,73 ,80 ,90 ,49 ,60 ,65 ,70 ,74 ,81 ,93 ,53 ,60 ,66 ,71 ,77 ,83 ,56 ,63 ,67 ,71 ,78 ,85 ,56 ,63 ,67 ,71 ,78 ,88 ,57 ,64 ,67 ,72 ,79, 90

we arrange the data set in ascending order

46,49,53,56,56,57,58,60,60,63,63,64,64,65,66,67,67,67,68,70,71,71,71,72,73,74,77,78,78,79,80,81,83,85,88,90,90,93

median is the central tendency of the data sets

hence, median lies between 68 and 70

hence, median= (68+70)/2

                        = 69

hence,the median age of the presidents at their death is

a.

69

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
