Answer:
first choice
Step-by-step explanation:
It is easier to create a probability table.
FOUND NOT FOUND TOTAL
REGION 1 0.70 0.30 1
REGION 2 0.40 0.60 1
REGION 3 0.30 0.70 1
The probability that during the search, the plane is not found in region 1 is 0.30. (1 - 0.70)
Answer:
2/9 chance or 22% chance
Step-by-step explanation:
You have to add up all the teachers, then turn it into a fraction. The sum of the teachers that you added up will be your denominator, then your numerator will be the probability number.
5+4=9
Answer:
There is no solution to these systems of equations.
Explanation:
To solve the system of equations: 6x−2y=5 and 3x−y=10, let us find the value of y in terms of x using second equation.
It is obvious that
3x=y+10 or y=3x−10
Now putting
y=3x−10 in first equation i.e.
6x−2y=5 , we get 6x−2(3x−10)= 5 or 6x−6x − 20 = 5 or −20 = 5, which is not possible
