Answer:
19, 29, 29, 37, 41
Explanation:
1. What we know: x y 29 z 41
(x+y+29+z+41)/5 =31
x y and z each >9 and prime
Possibile numbers: 11, 13, 17, 19, 23, 29, 31, 37, 41
2. (x+y+29+z+41)/5 =31
x+y+29+z+41 = (31×5)
x+y+z = (31×5) -29 -41
x+y+z = 85
z>=29
x<=29
y<=29
x and y can be 11, 13, 17, 19, 23, 29
z could be 29, 31, 37, 41
At least one if them must equal 29 because it's the mode.
So two of them must equal 56
11+29=40 so both numbers cannot be less than or equal to 40
This means y is 29 because x + z has to equal 56 and that wouldn't be possible if x equals 29.
Now we know x+z=56
Possible numbers: 19+37
I found these by doing 56- each possible number for x and seeing if that equaled a possible number for z. For example 56-11=45 but z cannot be 45 therefore x cannot be 11 and so on.
Then you just plug in the numbers!
19, 29, 29, 37, 41
This was so much fun to solve! I hope this is helpful, let me know if you have any questions! You got this :)
