How many solutions can be found for the equation 4z + 2(z - 4) = 3z + 11
Gnom [1K]
4z+2(z-4)=3z+11  perform indicated multiplication on left side

4z+2z-8=3z+11  combine like terms on left side

6z/-8=3z+11  add 8 to both sides

6z=3z+19  subtract 3z from both sides

3z=19  divide both sides by 3

z=19/3 

z=6 1/3

So there is only one solution when z=6 1/3

The mean life of a particular brand of light bulb is 1200 hours. if you know that at about 95% of this brand of bulbs will last
Snowcat [4.5K]
<span>204
   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>
