Susana=s
maria=m
m= 3s/5
s+m=56
s+(3s/5)=56
(5s+3s)/5=56
8s=56*5
8s=280
s=280/8
s=35
35 --->5/5
x ---> 3/5
x= (3/5)*35 / (5/5)
x=21
edad de maria= 21 años

Answer:
Step-by-step explanation:
<u>Given</u>
- Total applicants = 431
- Applicants with graduate degree and over 5 years of experience = 103
Probability = favorable outcomes/total outcomes
<u>Required probability </u>
- 103/431 = 0.2390 rounded to 4 decimal places
Answer:
d. The equation has one solution and there is not enough information to determine the direction of the parabola.
Step-by-step explanation:
For a general quadratic equation
y = ax² +bx +c
the solution is

The discriminant (D) is the part of the quadratic formula underneath the radical: b² - 4ac.
D tells us whether there are
- two different real solutions
- two identical real solutions ("one solution")
- two complex solutions.
If D= 0,

and there are two identical solutions ("one solution").
The direction of the parabola depends on the sign of a.
That information is not given, so we cannot determine the direction of the parabola.
