Answer: The square root of 81/49 is the answer
Step-by-step explanation:
B-(-7)= -1
First negative multiply by negative is POSITIVE.
So: B+7= -1
Subtract 7 from both sides
B= -7-1
B= -8.
Answer: -8.
To Check Answer: Plug in the variable of B in the original equation.
So: -8-(-7)= -1
-8+7= -1
-1= -1
If the Solution works out the answer is right.

Answer:
The probability that students will passing at least on course=0.80.
Step-by-step explanation:
We are given that a student is taking two courses, history and math.
The probability the student will pass the history course =P(A)=0.60
The probability that the student will pass the math course=P(B)=0.70
The probability that the students will pass the both course=
We have to find the probability that student passing at least one course.It means we have to find the probability of
We know that formula
Using the formula we get
The probability that students will passing at least on course=0.80.
