Answer:
9.42
Step-by-step explanation:
C=2πR
because your diameter is 3, your radius is 1.5, so just plug in your number.
C=2π(1.5)
C=9.42
True, this equation is a quadratic equation,.
Answer:
9 inches
Step-by-step explanation:
The population is within 6 standard deviations of the mean with a confidence of 99.7 percent, 3 above and 3 below
The standard deviation of the sample mean is equal to the population standard deviation divided by the square root of the sample size
population standard deviation = 36
sample size = 144
standard deviation of the sample mean = 36/ sqrt(144)
=36/12
=3
The margin of error is the number of standard deviations above the mean * the standard deviations
margin of error = 3 * 3
= 9 inches
-450 + 12x.....this is basically stating that the sewing machine and some fabric cost him $ 450....and he is selling each blanket for $ 12 a piece.
The total amount he earns is 12x....where x is the number of blankets
