4
_ = y
2x
Let's solve for y.<span><span>4<span>2x</span></span>=y</span>Step 1: Multiply both sides by x.<span>2=<span>xy</span></span>Step 2: Flip the equation.<span><span>xy</span>=2</span>Step 3: Divide both sides by x.<span><span><span>xy</span>x</span>=<span>2x</span></span><span>y=<span>2x</span></span>Answer:<span>y=<span>2<span>x</span></span></span>

Answer:
And we want to find this probability:
And we can find this probability:
And using the normal table or excel we got:
Step-by-step explanation:
For this case we have the following info given:
represent the sample size
represent the true proportion
The sample proportion can be approximated with this distribution:
The mean is given by:
And the deviation is given by:
And we want to find this probability:
And we can use the z score formula given by:
And replacing we got:
And we can find this probability:
And using the normal table or excel we got:
