I really need help! Mr Garcia has 15 boys and 10 girls in his math class. He selects two students at random to demonstrate how they solved the day’s challenge assignment. What is the probability that both students are girls? (Leave the answer in simplified fraction form.)

In the figure shown below, m < 40 and ab =8. which equation could be used to find x?

The means and mean absolute deviations of the individual times of members on two 4x400-meter relay track teams are shown in the table below. means and mean absolute deviations of individual times of members of 4x400-meter relay track teams team a team b mean 59.32 s 59.1 s mean absolute deviation 1.5 s 245 what percent of team b's mean absolute deviation is the difference in the means? 9% 15% 25% 65%

What is the solution to the system of equation graphed belowa.(0,-4)b.(2,5),1),-3)
