Answer:
80 square m
Step-by-step explanation:
We are given that
Mean=150 m
S.D=4 m
We have to find the variance of the total length of the wire in the coils.
Let X1, X2,X3,X4 and X5 are random variable of sample space of coil are choosing.
Var for all i=1 to 5
Let X be the total length of coils
Hence, the variance of the total length of the wire in the coils=80 square m
I’m thinking it’s the third option but not 100% sure, sowy
Answer:
C
Step-by-step explanation:
y=mx+b
m(slope)=rise/run=1
b(y intercept)=2
y=x+2
F(10) = (10)^2 + 1
= 100 + 1
= 101
101 is the answer
Let checkers be x and checker boards be y
x = 24 * y or
y = x/24
