Answer:3 and 1/8
Step-by-step explanation:by adding
To move it 1 to the left, we make x into (x+1), so we have (x+1)². Conversely, if we wanted to move it to the right, we'd subtract 1 from x. Next, we have to vertically stretch by a factor of 3, meaning that we have to multiply the whole thing (at the current point) by 3, turning our equation into 3(x+1)². Lastly, we must reflect over the x axis, which is the line g(x)=0. If we want to reflect over g(x), we essentially multiply g(x) by -1, making -g(x)=3(x+1)². However, we want to solve for g(x), not -g(x), so we multiply both sides by -1 to end up with -3(x+1)²
Procedure:
1) calculate the number of diferent teams of four members that can be formed (with the ten persons)
2) calculate the number of teams tha meet the specification (two girls and two boys)
3) Divide the positive events by the total number of events: this is the result of 2) by the result in 1)
Solution
1) the number of teams of four members that can be formed are:
10*9*8*7 / (4*3*2*1) = 210
2) Number of different teams with 2 boys and 2 girls = ways of chosing 2 boys * ways of chosing 2 girls
Ways of chosing 2 boys = 6*5/2 = 15
Ways of chosing 2 girls = 4*3/2 = 6
Number of different teams with 2 boys and 2 girls = 15 * 6 = 90
3) probability of choosing one of the 90 teams formed by 2 boys and 2 girls:
90/210 = 3/7
