Find the unit rate:
-1.2 tons
------------- = -0.15 ton/day, or -3/20 ton/day
8 days
Answer:
2
Step-by-step explanation:
12x+6=20-10 (subtract 6 to -10)
12x=20x+-16 (subtract 20)
-8=-16 (divide -16 by -8)
x=2
The vertex to the equation is, (4,2)
The z-score of the data can be calculated by the formula expressed as follows:
z = ( score - mean ) / standard deviation
z = (126 - 150 ) / 11 = <span>-2.18
</span>
A z-Score<span> is a statistical </span>measurement<span> of a </span>score's<span> relationship to the mean in a group of </span>scores<span>. A </span>Z-score<span> of 0 means the </span>score<span> is the same as the mean.</span><span>
</span>
