I just figured it out so I’ll answer it on this account lol.
Q1 = 32, Q2 = 45, Q3 = 52
Interquartile range = 52 - 32 = 20
Range = 68 - 21 = 47
Answer:
The correct option is A.
Step-by-step explanation:
Domain:
The expression in the denominator is x^2-2x-3
x² - 2x-3 ≠0
-3 = +1 -4
(x²-2x+1)-4 ≠0
(x²-2x+1)=(x-1)²
(x-1)² - (2)² ≠0
∴a²-b² =(a-b)(a+b)
(x-1-2)(x-1+2) ≠0
(x-3)(x+1) ≠0
x≠3 for all x≠ -1
So there is a hole at x=3 and an asymptote at x= -1, so Option B is wrong
Asymptote:
x-3/x^2-2x-3
We know that denominator is equal to (x-3)(x+1)
x-3/(x-3)(x+1)
x-3 will be cancelled out by x-3
1/x+1
We have asymptote at x=-1 and hole at x=3, therefore the correct option is A....
Your answer would be 288. Also, did you mean 8/9? Hope I helped!
Answer:
The mass of cocoa in chocolate candy is 3 g.
Step-by-step explanation:
30gr chocolate candy, mark on its packaging that it contains 10% cocoa, how many grams of cocoa does this represent?
mass of chocolate candy = 30 g
cocoa contains = 10 %
Now the mass of cocoa = 10 % of 30 g = 0.1 x 30 = 3 g
Mass of cocoa in the candy is 3 g.
Answer:
8 OR -8 OR Both
Step-by-step explanation:
-2 x 4 = -8
-8 x -8 x -8 = -64
Square root = 8 OR -8
1 to the 9th power = 1
-8 / 1 = -8
8/1 = 8
Hope that helps!
