Answer:
6x^8y^5
Step-by-step explanation:
(3)(2)= 6
add the exponents for the variables
No, a line of symmetry should cut the shape or object in half and represent a perfect mirror image.
That would be 16.625 pounds and/or 266 pounds
Answer:
Probably unequal ( B )
Step-by-step explanation:
<u>experimental group = 10</u>
using 85% ethanol gasoline
mean = 240 pounds per 100 miles
standard deviation = 20 pounds
<u>control group = 14 vehicles </u>
using regular gasoline
mean = 252 pounds per 100 miles
standard deviation = 15 pounds
comparing the sample variance of each group shows that they are probably unequal using the equation below
Variance for a sample set of data = ∑ ( x - X ) ^2 / n - 1
where n = number of events
X = mean value
x = value of events
