Answer:

Step-by-step explanation:
If the initial number is n, one less than n is n - 1, and one more than n is n + 1. so we have:

At first I thought this answer was too easy, so I tried for n is 6.

This is really cool! Hope this helps!
Answer:
f(x) = cos(x)
Step-by-step explanation:
tanx cscx = (sinx/cosx) * (1/sinx) = 1/cosx
1/f(x) = 1/cosx
f(x) = cos(x)
Third Period: 4, 5, 3, 4, 2, 3, 4, 1, 8,
2, 3, 1, 0, 2, 1, 3
Measures of central tendency are methods
to which an investigator can locate the most central value, or the reoccurring or
frequent most value in the set of parameter or statistic. There are three:
Mean. Is the average of the data values
Median. The middlemost value or digit in
the data set
Mode. The determining the most frequent
parameter
To identify which of these three suits
the given, arranging them first is a must. Ascending to descending.
Third Period: 0,1,1,1,2,2,2,3,3,3,3
4,4,4,5,8,
The best is mode, why? Because if you
observe there is a number most frequent in the data value and it is the fastest
way.
Mode = 3
V=pi (r^2) h/3
=pi (10^2)(4)/3
=(400/3) pi
or
=(400 pi)/3
Ratio of Nickel to Zinc:
( 2/7 ) = ( Nickel /4.9)
Nickel = 1.4 lbs.
Ratio of Copper to Zinc:
( 9/7 ) = ( Copper /4.9)
Copper = 6.3 lbs.
Alloy = Zinc + Nickel +
Copper
Alloy = 4.9 lbs. + 1.4 lbs.
+ 6.3 lbs.
Alloy = 12.6 lbs.

this answer will be a good h<span>elp for you.</span>
