Step-by-step explanation:
Answer:
g=41
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(g−7)=2(10+g)
(3)(g)+(3)(−7)=(2)(10)+(2)(g)(Distribute)
3g+−21=20+2g
3g−21=2g+20
Step 2: Subtract 2g from both sides.
3g−21−2g=2g+20−2g
g−21=20
Step 3: Add 21 to both sides.
g−21+21=20+21

Hey, um, I dont know if ur still doing the whole stop the hackers thing, but there's this one user, echo2155, that I've seen post a link (or a bunch, not sure). I don't remember what they said, because their answer got deleted. I just figured I'd tell u, because I want to stop it too. It's really anoying when people do it on my questions becuz they use up a question and other people can't answer. I report as many as I can, but there's so many people that do it. I hope this is what ur looking for, bye!
The formula to calculate the z-score of a certain value is:
z = (x - (mean))/(standard deviation)
In this example, the x-value is 450, the S.D. is 100, and the mean is 500.
So, substitute these values into the formula.
z = (450-(500))/100
z=-50/100
z=-0.5
Therefore, the z-score is -0.5.
