Answer: 84
Step-by-step explanation: 7 Times 12 because each foot is 12 inches
Answer:
Probability of a sample that contains exactly two defective parts is .0037 or .37%
Step-by-step explanation:
As we know if P is the probability of achieving k results in n trials then probability formula is P = 
In this formula n = number of trials
k = number of success
(n-k) = number of failures
p = probability of success in one trial
q = (1-p) = probability of failure in one trial
In this sum n = 5
k = 2
number failures (n-k) = (5-2) = 3
p = 2% which can be written as .02
q = 98% Which can be written as .98
Now putting these values in the formula
P = 
P = 
= 5×4×3×2×1/3×2×1×2×1
= 5×2 =10
P = 10×(.02)²×(.98)³
= .0037 or .37%
So first you have to multiply 21 by .1 to figure out ten percent
you then get 2.1
you add 21 and 2.1 together and get 23.1
then since you have 3 people you divide by 3 and get 7.7
therefor 7.7 is your answer
It should be 75×3=115 then 115×4=160 so 160 should be the answer!
Since they gave you the boxes you need the first number to be zero therefore having the quotient starting with zero. Then you may divide normally
