The weight of oranges growing in an orchard is normally distributed with a mean weight of 5.5 oz. and a standard deviation of 1.5 oz. Using the empirical rule,
determine what interval would represent weights of the middle 95% of all oranges
from this orchard.

Graph red beads cost $1 an ounce and gold beads cost $3 an ounce. juanita wants to purchase a 12-ounce mixture of red and gold beads that she can sell for $2 an ounce. the solution of the system shows the number of beads needed for juanita to break even. x + y = 12, x + 3y = 24 how many ounces of red beads will juanita buy to break even? how many ounces of gold beads will she buy?
