Remove parentheses and combine like terms...
then subtract constants from both sides
isolate variables and constants
use the division property and solve for x
Answer:
True
Step-by-step explanation:
The sum of cubes a^ 3 + b^ 3 = (a + b) (a ^2 − a b + b^ 2 )
We need to determine if 216x^3 is a cube and 64 is a cube
216 = 6*6*6
216 x^3 = (6x) ^3
and 64 = 4*4*4 = 4^3
So 216x^3 +64 = (6x)^3 + 4^3
Answer: 139
Step-by-step explanation:
As per given , we have
The amount of caffeine per cup is ranging from 60-180 mg.
Range = Maximum - Minimum = 180 -60 =12
According to Range -rule ,
Standard deviation =
Formula for sample size : , where z* is critical z value and E is margin of error.
By z-table , the critical z-value for 95% confidence interval = 1.96
E= 5
Put all values in formula , we get
Hence, 139 cups of coffee would have be included in the sample.
