Answer:
2.2 results in a true equation, 2.2 is a solution to the equation.
Step-by-step explanation:
Step 1. Substitute the number for the variable in the equation.
Step 2. Simplify the expressions on both sides of the equation.
Step 3. Determine whether the resulting equation is true.
If so, the number is a solution.
If not, the number is not a solution.
Answer:
0.70
Step-by-step explanation:
According to the given question,
P(A) = 0.60
P(B) = 0.25
P(A and B) = 0.15
And we are asked to find P(A or B) ,
We know,
- P(A or B) = P(A) + P(B)-P(A and B)
Putting the values we get,
- P(A or B) = 0.60 + 0.25 - 0.15
Thus option B is correct one.
The last option:The change in y-values is constant for evenly spaced x-values.
Remember that the change in y divided by the change in x is the slope of a line and it is constant.
Answer:
x=6
Step-by-step explanation:
Simplify
-2/x+4=4/x+3
4=6/x+3
6/x=1
x=6
