The solution for the problem is as follows:
((12x + 15y)/228) = 13
x + y =228
x = kentucky bluegrass
<span>y = chewings fescue
</span>
By systems of linear equations, the answers would be:
x = 152
y = 76
Therefore, there should be 152 pounds of Kentucky bluegrass to be used and 76 pounds of chewings fescue.

Answer:
Step-by-step explanation:
- The Z-score allows you to decide if your sample is different from the population mean. In order to use z, you must know four things:
- The population mean.
- The population standard deviation.
- The sample mean.
- The sample size.
- Usually in stats, you don’t know anything about a population, so instead of a Z score you use a T-Test with a T Statistic.
- The major difference between using a Z score and a T statistic is that you have to estimate the population standard deviation. The T test is also used if you have a small sample size (less than 30).
