Suppose our data set is:
2,4,6,8
the mean of the above data is:
(2+4+6+8)/4=20/4=5
Increasing the above value by 8
10,12,14,16
the mean will be:
(10+12+14+16)/4
=52/4
=13
The difference in the two mean values i
13-5=8
Thus we conclude that if we increase our values by 8, the mean increases by 8
Answer:
Logarithm
Step-by-step explanation:
Log is short for logarithm. Related terms include natural log or ln. There are many properties and equations that utilize the two and how to use them together to simplify and solve equations.
Answer:
-4.5
Step-by-step explanation:
this the work, -4.5-4.5-4.5-4.5
The lateral area is pi*r*s where s is the slant height of the cone. So in this case pi*r*s=12pi so the slant height s = 12pi / 2pi = 6. The height of the cone will be h = sqrt(6^2 - 2^2) by Pythagoras or h=sqrt(32) = 4*sqrt(2). Now for the volume: for a cone V = (1/3)*pi*r^2*h so here V = (1/3)*pi*2^2*4*sqrt(2) which gives us V = (16/3)*pi*sqrt(2) or answer A.<span>
