Answer:
wow nice
Step-by-step explanation:
If you're paying attention in your statistics class, you know that about 68% of the data lies within one standard deviation of the mean. That is, between
.. 20.6 -2.2 = 18.4
and
.. 20.6 +2.2 = 22.8
Selection A is appropriate.
Answer:
Step-by-step explanation:
Using the formula
Initial -final/initial =%/100
89-72/89 =%/100
17/89 =%/100
Making %subject of the formula
% =17*100/89
So % =1700/89
%= 19.101
Therefore rounding off the answer we have
X=19%
The expression that gives the number of Jackets that can be made from a fabric of 1634 yards will be found as follows:
let the number of jackets be x.
the total length of material required to make x jackets cannot exceed 1634 yards, it can be equal to or less than 1634. Thus, the expression will be given as follows:
amount required to make one jacket is 378,hence:
378x≤1634
x≤4.32275
approximating the above we get:
x≤4
