Y=2x+7 is already in its simplest form. It can be used to graph.
First combine like terms.
7+9=16
16+p=17
Subtract 16 from both sides of the equation.
16-16+p=17-16
p=1
You can check to see if the solution is true by substituting 1 into the original equation.
7+1+9=17
17=17
Given that an experiment results in one of the sample points E1, E2, E3, E4,
or E5.
Then P(e1) + P(e2) + P(e3) + P(e4) + P(e5) = 1
If P(E1)=0.1, P(E2)=0.1, P(e4)=0.2, and
P(E5)=0.3., then P(E1) = 1 - 0.1 - 0.1 - 0.2 - 0.3 = 0.3
Therefore, P(e3) = 0.3
That should be your final answer.
Hope this helps!
It is -5/8x (the slash represents a fraction sign)
