Answer:
0.15%, or 15/100 of 1%, or 3/20 of 1%
Step-by-step explanation:
68% of the data lies within 1 standard deviation of the mean (23.3 oz), or between 23.1 oz and 23.5 oz.
95% of the data lies within 2 std. dev. of the mean, or between 22.9 oz and 23.3 oz.
99.7% of the data lies within 3 std. dev of the mean, or between 22.7 oz. and 23.1 oz.
The remaining area under the curve is 100% - 99.7%, or 0.3%, Only half of this, or 0.15%, is to the left of 22.7 oz.
D = √(x2 - x1)^2 + (y2 - y1)^2) =
= √(6 + 1)^2 + (-2 - 4)^2) =
= √ (7^2 + 6^2) =
= √(49 + 36) =
= √85
Answer:
i believe C does not belong because it is the only one without x
Notice that you have a difference of cubes:
which can be factored using the rule,
So,
and just to make things look nicer, we can pull out 1/6 from the first factor and 1/36 from the second to get
R(r+r^2)=(r)(r^2)
R^2+r^3=r^3
R^2=0
R=0
