4s : 5g 

How many shovels of gravel are needed for 64 shovels of sand?
64s : Xg 

We need to calculate the value of X
4s : 5g

</span><span>64s : Xg 

4s.Xg = 5g.64s
X = (5g*64s)/4sg 

= 5*64/4

Viktor [21]

Answer:

Sample mean for solution 1:  19.27; sample mean for solution 2:  10.32

Step-by-step explanation:

To find the sample mean, find the sum of the data values and divide by the sample size.

For solution 1, the sum is given by:

9.7+10.5+9.4+10.6+9.3+10.7+9.6+10.4+10.2+10.5 = 192.7

The sample size is 10; this gives us

192.7/10 = 19.27

For solution 2, the sum is given by:

10.6+10.3+10.3+10.2+10.0+10.7+10.3+10.4+10.1+10.3 = 103.2

The sample size is 10, this gives us

103.2/10 = 10.32
