The probability that Stu buys a sandwich is 0.5. The probability that Stu gets the bus is 0.6.
Assuming the events are independent, what is the probability that Stu buys a sandwich and gets the bus?

P(S+B)=0.5*0.6=0.3

Step-by-step explanation:

Use the multiplication rule if the events are independent.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
