The standard deviation is the square root of the variance
so if the variance is 256, then the standard deviation is : sqrt 256 = 16 <==
Answer:
Step-by-step explanation:
Answer:
x = 7.5
Step-by-step explanation:
Since DF bisects ∠CDE then
∠EDF = ∠CDF, hence
8x = 4x + 30 ( subtract 4x from both sides )
4x = 30 ( divide both sides by 4 )
x = 7.5
Answer:2 weeks
Step-by-step explanation: if you subtract 1800 by 150 for the two weeks you will get 1500 and if you add 1100 by 200 every week you will get a hundred and fifty
The actual block is 1800 feet long and 1260 feet wide. We know that 1 foot is equivalent to 12 inches.
Luke is now using the Feet scale measurement.
Solving for the area in square inches is shown below:
Area = L * W
Area = (1800 feet *12 inches/1 foot) * (1260 feet *12 inches/1 foot)
Area = 326.592 x10^6 inches²
