3/4 = 12/x
this is a proportion, so we cross multiply
(3)(x) = (4)(12)
3x = 48
x = 48/3
x = 16
now notice this.....12/16 reduces to 3/4....probability's are nothing but equivalent fractions
Answer:
Step-by-step explanation:
a₂/a₁ = ⅘
This is a geometric sequence with initial term = 5 and common ratio = ⅘
a₇ = a₁(⅘)⁷⁻¹ = 5(⅘)⁶ = 4⁶/5⁵= 4096/3125 ≅ 1.311
C
Because the graph of the line is y = 2x + 2
The graph is shaded above the line, so we want y values above the line and since it is shaded in (red and not dashed), we want the values above and on the line (aka greater than or equal to SIGN)
If x' & x" are the roots (or x intercepts) of a quadratic equation, then it could be written:
y= (x-x')(x-x")
Since -6 & +6 are the roots of the quadratic function, then it could be written
as follows y= (x+6)(x+6) ===> y= x²-36. So the answer is B
