If a factory manufactures office chairs, and the binomial variable has mean of 10 and standard deviation of 3, based of the distribution of D
- The Probability of identifying the defective chair, would be an accurate interpretation of the value 0. 1
Mean of binomial distribution = np = 10
Variance of binomial distribution = npq = 9

Answer:
18 mph
Explanation:
It takes Tiffany 1/4 hours to walk 4.5 miles. In equation form, it is:
x/4=4.5
x=18
Each point should satisfy the equation of the line it belongs to.
This means that:
for the equation of the first line (y=x+b), the point (p,r) satisfies this equation, thus: r = p + b ....................> equation I
for the equation of the second line (y=2x+b), the point (2p,5r) satisfies this equation, thus: 5r = 4p + b ...................> equation II
Subtract equation I from equation II to eliminate the constant b:
5r-r = 4p+b-p-b
4r = 3p
Thus, r/p = 3/4
