15*18= 270 so 270 feet of carpet
Answer:
y = −7x + 17
Step-by-step explanation:
y + 4 = -7 (x - 3)
add -4 to both sides
y + 4 + -4 = -7x + 21 + -4
y = -7x + 17
Answer:
(60.382 ; 83.998)
Step-by-step explanation:
The confidence interval is given as :
Mean ± Margin of error
Mean = 72.19
The margin of error is : Tcritical * s/√n
n = 13 ; s = 15.88
Tcritical at 98%, df = 13-1 = 12 = 2.681
Margin of Error = 2.681 * 15.88/√13 = 11.808
Confidence interval = 72.19 ± 11.808
(60.382 ; 83.998)
Answer:
d
Step-by-step explanation:
P(A and B) = P(A) x P(B)
0.6 = 0.8 x P(B)
0.6/0.8 = P(B)
P(B) = 0.75
The correct answer for the given mathematical question above would be option A. The statement that shows two polynomials 4x + 6 and 2x^2-8x demonstrating the closure property when multiplied is that, 8x^3-20x^2-48x is a polynomial. The answer is option A for the given reason: <span>(4x+6)(2x^2 -8x)= 8x^3 -20x^2 -48x</span>
