Median is the middle number in a sorted list of values.18 20 37 49 56Median = 37
To find the mean you add all the numbers together then divide by how many there are. Ex. 5+10+6+6+5+12+5=49 49/7=7 Mean=7 To find the median you put the numbers from least to greatest the find the number in the middle. (note: if there are two numbers in the middle add hem and divide by two.) Ex. 5,5,5,6,6,10,12 Median:6 To find the mode you look for the number that appears the most. (note: There can be more than one mode or there can be no mode) Ex. 5,5,5,6,6,10,12 Mode:5
P( at least one card is a heart) = 1 - P( 0 hearts) P(0 hearts) = (39/52)(38/51)(37/50)(36/49)(35/48) P( at least 1 heart) = 1- (39/52)(38/51)(37/50)(36/49)(35/48) =0.778466
It is 1 - prob(none of the four is a heart) = 1 - (39/52)*(38/51)*(37/50)*(36/49) = 1 - 1974024/6497400 = 0.6962
I am now going to list the square numbers with their roots, just to be helpful. 1=1 2= 4 3= 9 4= 16 5= 25 6= 36 7= 49 8= 64 9= 81 10= 100 11= 121 12= 144 13= 169 14= 196 15= 225 16= 256 17= 289 18= 324 19 = 361 20 = 400 21 = 441 22 = 484 23 = 529 24 = 576 25 = 625 26 = 676 27 = 729 28 = 784 29 = 841 30 = 900 31 = 961 32 = 1024 33 = 1089 34 = 1156 35 = 1225 36 = 1296 37 = 1369 38 = 1444 39 = 1521 40 = 1600 41 = 1681 42 = 1764 43 = 1849 44 = 1936 45 = 2025 46 = 2116 47 = 2209 48 = 2304 49 = 2401 50 = 2500
It is 36, the number halfway between the two middle numbers, 34 and 38.
34
The median is 67.
35 is the median. It is the middle value when they are arranged in order.
The median is 49.
