scores on a short quiz in statistics were 0,1,2,3,...,10 points, depending on the number answered correctly out of 10 questions. the mean score was 6.7 and standard deviation was 1.2 assume the scores to be normally distributed, determine the maximum score of the lowest 10% of the class​

Find the number of real number solutions for the equation. x2 + 5x + 7 = 0 0 cannot be determined 1 2

X2 + y 2 = 36 x + y = 6 solve the system of equations.

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y > 2x + 3y is less than negative 3 over 2 times x minus 4part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points)part b: is the point (â’4, 6) included in the solution area for the system? justify your answer mathematically. (4 points)
