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
Answer:
None of them are irrational.
Step-by-step explanation:
An Irrational Number is a real number that cannot be written as a simple fraction.
Therefore:
-4 can be written as -4/1
2/9 is already in fraction
8.26 can be written as 826/100
11 can be written as 11/1
None of them are irrational.
However numbers like are irrational as they can not be represented as fractions.
Answer: x < 11.9
Step-by-step explanation:
Step-by-step explanation:
(-7+1)/(5-1)=-6/4= -3/2 is the slope
answer is C
If you divide you get 0.2201
Which is approximately 0.22
