Answer:

10.2 cm

Step-by-step explanation:

Data : 10.05 cm, 10.1 cm, 9.741 cm, 10.6 cm, 10.5 cm

We are supposed to find the average

Average = \frac{\text{Sum of all observations}}{\text{No. of observations}}

Average = \frac{10.05+10.1+9.741+ 10.6+10.5}{5}

Average = \frac{50.991}{5}

Average =10.1982

Rounding off gives Average =10.2

Hence the average of the measurements with the correct number of significant figures is 10.2 cm

Natali5045456 [20]

The right system of equations to describe the situation would be on the form:

x1 = 8000 + y1*t

and

x2 = 8000 + y2*t

where x1 and x2 represents the total money of Imogene and her friend respectively at the end of t years.

Now for the value of amount earned, y1 and y2:

y1=8000*0.08

y2=2000*√(t-2)
