To select a committee of 3 people from 10, you can use the combination formula ( C(n, k) = \frac{n!}{k!(n-k)!} ). Here, ( n = 10 ) and ( k = 3 ). This gives ( C(10, 3) = \frac{10!}{3!(10-3)!} = \frac{10 \times 9 \times 8}{3 \times 2 \times 1} = 120 ). Therefore, there are 120 ways to select a committee of 3 people from 10.

The number of combinations of 7 items taken from a set of 10 can be calculated using the formula for combinations, which is ( C(n, r) = \frac{n!}{r!(n-r)!} ). For 7 in 10, this is ( C(10, 7) = \frac{10!}{7!(10-7)!} = \frac{10!}{7!3!} = \frac{10 \times 9 \times 8}{3 \times 2 \times 1} = 120 ). Thus, there are 120 combinations of 7 in 10.
To find the number of different seating arrangements of 10 people in 5 chairs, we can use the permutation formula ( P(n, r) = \frac{n!}{(n - r)!} ), where ( n ) is the total number of people and ( r ) is the number of chairs. Here, ( n = 10 ) and ( r = 5 ). Thus, the calculation is ( P(10, 5) = \frac{10!}{(10 - 5)!} = \frac{10!}{5!} = 10 \times 9 \times 8 \times 7 \times 6 = 30,240 ). Therefore, there are 30,240 different seating arrangements.
The interior angle of a regular decagon can be calculated using the formula ((n-2) \times 180^\circ / n), where (n) is the number of sides. For a decagon, (n = 10), so the calculation is ((10-2) \times 180^\circ / 10 = 8 \times 180^\circ / 10 = 144^\circ). Thus, each interior angle of a regular decagon measures 144 degrees.
