Answer:

Step-by-step explanation:

marcus : deposits 25 + 15 each week(w)

25 + 15w

Philip : deposits 40 + 10 each week(w)

40 + 10w

when will they be equal.....set them equal and solve for w, the number of weeks

25 + 15w = 40 + 10w

15w - 10w = 40 - 25

5w = 15

w = 15/5

w = 3 <==== they will be equal at 3 weeks

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
