Answer:
The probability that a student is selected ta random is a man or received an A in the exam is 0.5714.
Step-by-step explanation:
In a class of 35 students there are 20 women and 15 men.
Compute the probability of selecting a men as follows:
![P(M)=\frac{15}{35}](https://tex.z-dn.net/?f=P%28M%29%3D%5Cfrac%7B15%7D%7B35%7D)
Compute the probability of selecting a women as follows:
![P(W)=\frac{20}{35}](https://tex.z-dn.net/?f=P%28W%29%3D%5Cfrac%7B20%7D%7B35%7D)
It is provided that 5 women and 4 men received A’s in the first exam.
Compute the probability of a a student getting an A and the student being a man as follows:
Compute the probability of a a student getting an A and the student being a woman as follows:
Compute the probability of a student receiving an A as follows:
![P(A)=P(M\ca A)+P(W|cap A)=\frac{4}{35}+\frac{5}{35} =\frac{9}{35}](https://tex.z-dn.net/?f=P%28A%29%3DP%28M%5Cca%20A%29%2BP%28W%7Ccap%20A%29%3D%5Cfrac%7B4%7D%7B35%7D%2B%5Cfrac%7B5%7D%7B35%7D%20%3D%5Cfrac%7B9%7D%7B35%7D)
Compute the probability that a student is selected ta random is a man or received an A in the exam as follows:
![P(M\cap A) = P(M) + P(A) - P (M\cap A)\\=\frac{15}{35}+\frac{9}{35}-\frac{4}{35}\\ =\frac{15+9-4}{35}\\ =\frac{20}{35}\\=0.571429\\\approx0.5714](https://tex.z-dn.net/?f=P%28M%5Ccap%20A%29%20%3D%20P%28M%29%20%2B%20P%28A%29%20-%20P%20%28M%5Ccap%20A%29%5C%5C%3D%5Cfrac%7B15%7D%7B35%7D%2B%5Cfrac%7B9%7D%7B35%7D-%5Cfrac%7B4%7D%7B35%7D%5C%5C%20%20%3D%5Cfrac%7B15%2B9-4%7D%7B35%7D%5C%5C%20%3D%5Cfrac%7B20%7D%7B35%7D%5C%5C%3D0.571429%5C%5C%5Capprox0.5714)
Thus, the probability that a student is selected ta random is a man or received an A in the exam is 0.5714.
It’s 7. take the equation given to you y=kx and then take each of the coordinates given and plug them in for x and y (3,21) 21=k(3) then divide the number being multiplied with k and divide it on both sides 7=k. then do that for the rest of them. you get 7 for all three
