Answer:
Margin of error =z-score value for chosen confidence level×population standard deviation
Assuming a 95% confidence level , then
z=1.96
standard deviation=5.75
Margin of error= 1.96×5.75=11.27
Answer:
About 3.67
Step-by-step explanation:
1 - 1/3 = 3.66666666667

Hope this helps! :)
Answer:
40
Step-by-step explanation:
210-x=50×2
or, 210-x=100
or, x=210-100
or, x=110
so,
z = 360-210-110
or, z = 40
This equation<span> has x terms on both the left and the right. To solve an </span>equation<span> like this, you must first get the variables on the same side of the </span>equal<span> sign. You can subtract 5x on each side of the </span>equal<span> sign, which gives a new </span>equation<span>: x + </span>5<span> = 10. hope this helps</span>
