Answer:
Step-by-step explanation:
If the value of y is same for both then we have equal right sides of equations
Solve this for x
- 50x - 30x = 70 - 10
- 20x = 60
- x = 60/20
- x = 3
Find the value of y
- y = 50*3 + 10 = 150 + 10 = 160
Correct choice is A
Discriminant = b^2 - 4ac; where a = 1, b = 9 and c = 14
d = (9)^2 - 4(1)(14)
d = 81 - 56
d = 25
the discriminant is greater than zero, so there are two real roots
I know the first 3 are c. I'm pretty sure the last one is a or d
Answer:
A
12x^4 + 10x^3-22x^2 - 15x
Step-by-step explanation:
Answer:
You should perform x trials until you observe a success.
Step-by-step explanation:
By process of elimination:
A binomial experiment is a statistical experiment that must meet certain requirements:
Each outcome is either a success (P) or a failure (Q).
All trials are independent.
There are a fixed number of "n" trials.
The probability of success, p, is the same for each trial.
