Answer:
hyperbola
Step-by-step explanation:
A graphing calculator shows the equation is that of a hyperbola.
__
Multiplying by the denominator gives ...
r(2 -3sin(x)) = 1
2r -3y = 1 . . . . . . . . substituting y=r·sin(x)
2r = 1 +3y . . . . . . . .isolating r
4r² = 1 +6y +9y² . . squaring both sides
4(x² +y²) = 1 +6y +9y² . . . . . substituting x²+y² = r²
4x² -5y² -6y -1 = 0 . . . . . . . . general form equation of a hyperbola
Answer:
c. 0.6
Step-by-step explanation:
A student cannot receive an A or a B simultaneously, so .
Grade of A equals .30 and the probability of receiving a grade of B equals .30.
This means that
The probability that a randomly selected student from this class will receive either an A or a B equals:
This is:
So the probability is 0.6, and the correct answer is given by option c.
