The length in standard notation is 2.17 + 8 = 10.17 ft
<h3>How to write in standard notation? </h3>
A standard notation is a form of writing a given number, an equation, or an expression in a form that follows certain rules.
For example 9.5 billions years can be represented as follows;
9,500,000,000 years.
Therefore, let's write 8 ft and 26 inches in standard form.
12 inches = 1 ft
26 inches = ?
cross multiply
length(ft) = 26 / 12
length(ft) = 2.16666666667
length(ft) = 2.17 ft
Therefore, the length in standard notation is 2.17 + 8 = 10.17 ft

Answer:
24.8 mins
Step-by-step explanation:
Time > timemark > frequency
0 – 10 > 10/2 = 5 > 5
10 – 20 > (10+20)/2 = 15 > 15
20 – 30 > (20+30)/2 = 25 > 13
30 – 40 > (30+40)/2 = 35 > 10
40 – 50 > (40+50)/2 = 45 > 7
The mean time for the 50 people is given by:
Mean = summation (mid time x frequency) / total frequency
Mean = [5x5 + 15x15 + 25x13 + 35x10 + 45x7] / 50
Mean = [25 + 225 + 325 + 350 + 315] / 50
Mean = 1240 / 50
Mean = 24.8 mins
2=10
3 =15
7=35
1=5
Constant of 1 is 5
