Answer
4+(-x),-x+4
Step-by-step explanation:
Answer:
2 (real) solutions.
Step-by-step explanation:
A quadratic always has two solutions, whether they are real or complex.
Sometimes the solution is complex, involving complex numbers (2 complex), sometimes they are real and distinct (2 real), and sometimes they are real and coincident (still two real, but they are the same).
In the case of
x^2+3x = 3, or
x² + 3x -3 = 0
we apply the quadratic formula to get
x = (-3 +/- sqrt(3^2+4(1)(3))/2
to give the two solutions
{(sqrt(21)-3)/2, -(sqrt(21)+3)/2,}
both of which are real.
9y-8y-y= 9-8-1 = 0y =0
subtract all like terms
0.63x12= 7.5 so the answer is 7.5
Answer:
25% of deliveries
Step-by-step explanation:
This is a uniform distribution with parameters a = 1.00 and b =5.00. With these conditions, the following probability distribution functions can be applied:
Therefore, the probability that X ≥ 4:00 p.m. is given by
Thus, 25% of deliveries are made after 4:00 p/m.
