The two line plots below shoe scores on a math quiz and an English quiz for a group of 30 seventh grade students. Based on the distribution of data, which observation is correct. (See attached image)

Achemist has 200 ml of a 10% sucrose solution. she adds x ml of a 40% sucrose solution. the percent concentration, y, of the final mixture is given by the rational function: the chemist needs the concentration of the final mixture to be 30%. how many milliliters of the 40% solution should she add to the 10% solution to get this concentration?

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 - 4x - 5 = 0

What is the value of the discrimination for the quadratic equation 0=×2+2+×2
