Ascientist wants to create 120 ml of a solution that is 30% acidic. to create this solution, she has access to a 20% solution and a 45% solution. how many millimeters of each solution should she combine to create the 30% solution? solve this problem using a system of two equations in two variables.

Which is a true statement comparing the graphs of x^2/6^2-y^2/8^2 = 1 and x^2/8^2-y^2/6^2 the foci of both graphs are the same points. the lengths of both transverse axes are the same. the directrices of = 1 are horizontal while the directrices of = 1 are vertical. the vertices of = 1 are on the y-axis while the vertices of = 1 are on the x-axis.

The random variable x is the number of occurrences of an event over an interval of ten minutes. it can be assumed that the probability of an occurrence is the same in any two-time periods of an equal length. it is known that the mean number of occurrences in ten minutes is 5.3. the appropriate probability distribution for the random variable

Which number line represents the solution set for the inequality - x 24?
