Answer:
$18.90 + $6.30 = $25.20
Step-by-step explanation:
200,000 because every decimal adds on
The number of ways to select 4 digits from 10 digits is
₁₀C₄ = 10!/(4!*6!)
= (10*9*8*7*6!)/(4*3*2*1*6!)
= (10*9*8*7)/(4*3*2)
= 210
If order is not important, the number of arrangements of 6,7,8,9 in any order is
4! = 4*3*2*1
= 24
The probability that these 4 digits are assigned is
24/210 = 0.1143
$54.29
This is because 5% of $51.70 is $2.59. The sum of the tax and bill would become $54.29.
Answer:
Step-by-step explanation:
18w⁴x⁹ /14w⁵x⁵ = 2*9*x⁹⁻⁵/ 2*7*w⁵⁻⁴
= 9x⁴/7w¹
a^m/a^n = a^m-n ; when m>n
a^m/a^n = 1/a^m-n ; when m<n
