The Geometric mean of these two numbers is 8.94(I didn't know if you had to round the nearest tenth or hundredth). Hope this helps!
How I got this answer:
M=<span>√(a1*a2)
M=</span><span>√(2*40)
M=</span><span>√(80)
M=8.94</span>
Answer: 11
Step-by-step explanation:
Let the 5 numbers be x,x+1,x+2,x+3 and x+4.
Therefore,
x + x+1 + x+2 + x+3 + x+4 = 65
5x + 10 = 65
5x = 65 - 10
5x = 55
x = 55/5
x = 11
Therefore, the 5 numbers are 11, 12, 13, 14 and 15.
The first number is 11

Answer:
Step-by-step explanation:
1.)1,2,3,4,5
mean=sum of all values/number of values
=1+2+3+4+5/5
=15/5
mean=3
Mode :
In the given data, no observation occurs more than once.
Hence the mode of the observations does not exist, means mode=0.
Median
1,2,3,4,5
Middle value is 3 so the median is 3.
2.)2,3,4,5,6,6
mean=sum of all values/number of values
=2+3+4+5+6+6/6
=26/6
mean =4.33
Mode
is that value of the observation which occurs maximum number of times so here mode is 6.
Median
2,3,4,5,6,6
4+5/2
9/2
median=4.5
3.)6,7,5,4,5,6,2,5
mean=sum of all values/number of values
=6+7+5+4+5+6+2+5/8
=40/8
mean =5
Mode
is that value of the observation which occurs maximum number of times so here mode is 5
Median
2,4,5,5,5,6,6,7
5+5/2
10/2
median=5
Answer:3
