First, lookup a standard normal table and see what the z-score is for 0.025 (one half of 100% - 95%) to allow for equal sized tails. You should find that the z-score is 1.96. That means that 95% of the time, the value should be within 1.96 standard deviations of the mean. Now let's calculate the standard deviation.
800 is 800 - 1200 = -400 to the left of the mean of 1200.
1600 is 1600 - 1200 = 400 to the right of the mean of 1200.
So we are an equal distance of 400 on both sides of the mean. And we know from the z-score of 1.96, that we're 1.96 standard deviations from the mean. So a little division will give us the standard deviation. Which is:
400 / 1.96 = 204.0816327
So the standard deviation of the light bulbs is 204</span>

<em>To solve for a variable, you just need to isolate the variable to one side.</em>
<h3>7.</h3>
For this, just divide both sides by r and <u>your answer will be </u>
<h3>8.</h3>
For this, divide both sides by nR and <u>your answer will be </u>
<h3>9.</h3>
Firstly, multiply both sides by T:
Next, subtract FV on both sides of the equation:
Lastly, multiply both sides by -1, and <u>your answer will be </u>
<h3>10.</h3>
Firstly, multiply both sides by 1000:
Lastly, divide both sides by tc and <u>your answer will be </u>
