How do you evaluate p6 if p equals 3?
When two characters are next to each other (like p6) this means multiplication. Therefore it can be written as p x 6. If you substitute p for 3 you have 3 x 6 which equals 18.
What is 4 fifths of 60 p?
4/5 of 60 p = 48 p
What is the probability that a machine with 7 components that function independently with a failure rate of 2 what is the probability that at least 4 failed?
probability of a machine component failing = 2/7 P(at least 4 failed) = P( 4 failed)+P(5 failed) +P(6 failed)+P(7 failed) Using binomial probability: P(4 failed ) =7C4 (2/7)^4 ((5/7)^3 = 0.084987 P(5 failed) = 7C5 (2/7)^5 (5/7)^2 = 0.020395 P(6 failed ) = 7C6 (2/7)^6 (5/7) = 0.002719 P(7 failed) = (2/7)^7 = 0.000155 Adding, P(at least 4 failures) = 0.108257
What is the variable value for -5 equals 7-p-2p?
p = 4
The quantity p minus five eighths times the quantity one fourth plus p?
The equation is as follows: p - 5/8 (1/4 + p). This equation expands to (1/4)p + p^2 - 5/32 - (5/8)p, which simplifies to p^2 - (3/8)p - 5/32. Now either solve for p using the quadratic formula or solve by factoring.
