Answer: I'll give you both the percentage and dollar amount. 75% = $144

Step-by-step explanation: first, I added up all the percentages to total 75%. then I took the total sales, and divided that by .75 (75% in decimal form), so:

1940 x .75 = 1455

1940 - 1455 = 144

In the expansion of

Mumz [18]

By the binomial theorem, the $x^2$ term in the expansion of $\left(1-\frac x4\right)^n$ is

$\dbinom n21^{n-2}\left(-\dfracx4\right)^2=\dfrac{n!}{2!(n-2)!}\dfrac{x^2}{16}$

which suggests that the contribution of the binomial coefficient should make up the remaining factor of 21. That is,

$\dfrac{n!}{2!(n-2)!}=\dfrac{n(n-1)}2=21\implies n=7$

That would a set of 5 numbers in ascending order with 4 being the middle one and the other 4 being the highest possible So it is

2, 3, 4, 9, 10

Mean is 28/5 = 5.6 answer

Answer:

x = 20

Step-by-step explanation:

Traingle ABC = Traingle DEC

4x-1×4×5 = x+2×4×5

80x-1 = 2×20x

80x-20x = 2+1

60x = 3

60÷3 = x

x = 20
