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

Answer:
The height h it will travel in t minutes
Height h = 6 + 20(t)
Oh=20t + 6
Step-by-step explanation:
A hot air balloon starts at a height of 6 feet above the ground and then rises at a rate of 20 feet each minute.
Initial height h0 = 6 feet
Then it travel 29 feet each minute
Rate = 20 feet/ minute
The height h it will travel in t minutes
Height h = 6 + 20(t)
