Find the pattern
z,Y,x,W,v,U
The letter from the end of the alphabet are skipped every letter
a,B,c,D,e,F
The pattern is the same as the end of the alphabet
Therefore, the next letter would be S as we have to skip one from U, this being T.
Answer:
45n
Step-by-step explanation:
We have
mean=mu=170
standard deviation=sigma=5
can now calculate the Zmin and Zmax using Z=(X-mean)/standard deviation
Zmin=(165-170)/5=-1
Zmax=(175-170)/5=+1
From normal probability tables,
P(z<Zmin)=P(z<-1)=0.15866
P(z<Zmax)=P(z<+1)=0.84134
P(165<x<175)=P(Zmin<z<Zmax)=0.84134-0.15866= 0.68269
Answer:
Length = 65 m
Width = 23 m
Step-by-step explanation:
Width = w
Length = 3w - 4
Perimeter of rectangle = 176 m
2*(length + width) = 176
2*( 3w - 4 + w ) = 176
2* ( 4w - 4) = 176
2*4w - 2*4 = 176
8w - 8 = 176 { add 8 to both sides}
8w = 176 +8
8w = 184
8w/8 = 184/8
w = 23 m
Length = 3w - 4
= 3*23 - 4
= 69 - 4
Length = 65 m

Just plug numbers into it. Make this a table.
n 0 1 2 3
y 1 6 11 16
