Answer:
8 1/4
Step-by-step explanation:
Solution by Formulas
converting mixed numbers to fractions, our initial equation becomes,
−11 -9
3×4
Applying the fractions formula for multiplication,
−11×−9
3×4
=99
12
Simplifying 99/12, the answer is
=814
The answer is (D) or 1728 In³
Answer: a=b , greater than
Step-by-step explanation:
Answer:
a) 25 is 3 standard deviation from the mean
b) Is far away from the mean, only 0,3 % away from the right tail
c) 25 is pretty close to the mean (just a little farther from 1 standard deviation)
Step-by-step explanation:
We have a Normal Distribution with mean 16 in.
Case a) we also have a standard deviation of 3 inches
3* 3 = 9
16 (the mean) plus 3*σ equal 25 in. the evaluated value, then the value is 3 standard deviation from the mean
Case b) 25 is in the range of 99,7 % of all value, we can say that value is far away from the mean, considering that is only 0,3 % away from the right tail
Case c) If the standard deviation is 7 then
mean + 1*σ = 16 + 7 =23
25> 23
25 is pretty close to the mean only something more than 1 standard deviation
