Which of the following statements regarding the expansion of (x + y)^n are
correct?
O A. The coefficients of x and y? both equal 1
B. For any term x^ay^b in the expansion, a - b = n.
C. The coefficients of x^n and y^n both equal 1.
D. The coefficients of x^ay^b and x^by^a are equal.

answer: the value of x is 7cm

step-by-step explanation:

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i

they go with it happens or they mite give a chance?

step-by-step explanation:

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
