Jack invested 57
Sam invested 38
57 over 38 minus 1,00
Answer:
Step-by-step explanation:
standard deviation σ =5000
Mean μ = 36500
X = 30000
Probability that tire fails to reach 30000 miles
P(< 30000) = P( z < (30000-36500) / 5000 )
= P ( z < - 1.3 )
= .0968 ( from z table )
refund per mile = .01
refund for 30000 mile = .01 x 30000 = 300
expected cost of promotion
= 300 x .0968
= 29.04
b )
refund of $50 is equivalent to shortage of milage by 50 / .01 = 5000 miles
Probability of miles less than 30000 - 5000 = 25000
P ( X < 25000 ) = P ( z < (25000 - 36500) / 5000 )
P ( z < - 2.3 )
= 0.0107 Answer .
The answer is pq^2, for it can be taken out of both monomials.
The missing height is 5 inches
Answer: $20.
Step-by-step explanation: The price of onions was $32 per kg, this price decreased by $12, so you need to subtract 12 from 32. 32 - 12 is $20.
