Basically you need to multiply the percent by the number.
If you have a calculator with statistical functions, that's the way to go.
On my TI-83, I typed in invNorm(0.88) and got the result z = 1.17.
88% of the area under the normal curve is to the left of z = 1.17.
Answer:
There is no solution to that equation.
Step-by-step explanation:
First thing to do is to put the second equation in terms of y. To do so the equation becomes y= 2/3x+5. Comparing those two equation you can see that the slopes are the same and thus means that the system has no solution.
Another way to see this is by graphing both of thee equations is a calculator and seeing there are no points of intersection.
5x6=30
6x6=36
You would need 1 more 6
I can't explain this very well, sorry.
Subtract 4 from each side
Divide both sides by 5
Take square root of both sides
Add 3 to both sides
