1. There
are 10, 000 combinations, you have 10 choices for the four digit and there are
10 x 10 x 10 x 10 which is 4-digit combination from 1-9. This is called combinations;
the calculation comes out to 10^4.
Answer:
Radius = 10 cm
Circumference = 20*pi cm
Step-by-step explanation:
Area of a circle = pi * r^2
100 = r^2
10 = r
Circumference = 2*pi*r
2*pi*10
20*pi
On Friday because if she danced 11 - negative 4 = 15. and 19 - negative 8=27. the closest would be Friday because on that day she danced for 2.6 hours.
Hope it helps.
solution
Mean of two smallest number (3+5 =8/2) =4
Mean of all the three (3+5+19 =27) 27/3 = 9
so the mean of two largest number is 19+5 = 24 /2 = 12
Final Answer
The mean of two largest Number is 12
