P = (2xy)/3c - 5y Make Y the subject of the formula

  P = (2xy)/3c - 5y Make Y the subject of the formula 2xy = P(3c - 5y) 2xy = 3Pc - 5Py 2xy + 5Py = 3Pc Y(2x + 5P) = 3pc Ans:Y = 3Pc/2x + 5p Follow Fiero Academy On IG

In an athletic competition, the probability that an athlete wins a 100m race is 1/8 and the probability that an athlete wins a 100m race is 1/8 and the probability that he wins in high jump is 1/4. What is the probability that he wins only one of the events?

 In an athletic competition, the probability that an athlete wins a 100m race is 1/8 and the probability that an athlete wins a 100m race is 1/8 and the probability that he wins in high jump is 1/4. What is the probability that he wins only one of the events? The Pr. Of winning only one event means it's either he win the 100m race OR the high jump. Rem. OR in probability means addition. 1/8 * (1 - 1/4) + 1/4 * (1 - 1/8) = 1/8 * 3/4 + 1/4 * 7/8 = 3/32 + 7/32 = 10/32 To the Lowest term: Ans = 5/16 Submit a question or another method of solving the above question in the comment section Visit myschool for more solutions Follow Fiero Academy on Instagram

The Probability that Musa passes English, Mathematics and Geography are 1/3, 2/5, and 3/4 respectively. What is the probability of passing all?

  The Probability that Musa passes English, Mathematics and Geography are 1/3, 2/5, and 3/4 respectively. What is the probability of passing all? Probability of passing all = Pr(Eng) and Pr(Maths) and Pr(Geog) Remember "and" means multiplication Therefore Pr(all) = 1/3 * 2/5 * 3/4 Ans = 1/10

A basket contains 50 eggs, 15 of them are bad. If the egg is taken out, find the probability that it is good.

  A basket contains 50 eggs, 15 of them are bad. If the egg is taken out, find the probability that it is good. Good eggs = 50 - 15/50  = 35/50  Breaking it down we have: Ans: 7/10

If x varies inversely as y and y varies directly as z, what is the relationship between x and z?

  If x varies inversely as y and y varies directly as z, what is the relationship between x and z?   X = k/y  And Y = kz Rel. = X = k/Z Therefore x varies inversely as z. Any better explanation? Drop it in the comments  Follow Fiero Academy On Instagram

Solve for x and y if x + y = 3 and 3x - y = 1

  Solve for x and y if x + y = 3 and 3x - y = 1 Solution    x + y = 3 +(3x - y = 1) We have; 4x = 4 Dividing both side we have  X = 1 What's your own way of solving it? Drop it in the comment.

If Y = (2x + 1)³, find dy/dx

  If Y = (2x + 1)³, find dy/dx Solution Y = (2x + 1)³ Let 2x + 1 = v therefore dv/dx = 2 Y = v³ (Remember 2x + 1 has been replaced with v) dy/dx = 3v² Applying the chain rule formula dy/dx = dy/dx *  dv/dx We have: 3v² * 2 3(2x + 1)² * 2 Ans: 6(2x + 1)² Helpful?  Let's know what you feel in the comment below    See how mytutor solved  thesame question Follow Fiero on Instagram

Given that Y = (X + 1)² , find dy/dx

  Given that y = (x + 1)² find dy/dx Solution Expanding our question: Y = (x + 1)² = y (x + 1)(x + 2) Multiplying our expanded question we have: X² + 2x + 1 Now differentiating: X² + 2x + 1 dy/dx = 2x + 2 Is this answer helpful?
